Split systems, which were discussed in our previous publication, are, of course, good, but not everyone can spend tens of thousands of rubles on the purchase and installation of such bulky units, and in some cases, such as a rented apartment or architects’ prohibitions, about You can't even dream of such air conditioners.

As always, there is a way out: these are compact table fans, universal floor fans and even column fans, as well as monoblock air conditioners - we’ll talk about these alternatives today.

⇡ Table fans

The most popular means of cooling for those born in the USSR, before and after, is a fan. A propeller on a stand is an invariable attribute of most Soviet apartments, offices, buses, cars, and more.

Traditional Vitek fan on stand: protective cover and three speeds

Table fans, KO suggests, are designed to be installed on a table or on a windowsill. The blades of such fans are small, as is the power - when compared with other types of similar devices. Such fans are designed to create a comfortable zone for at least one person, and their main advantages are their compactness and the ability to quickly move them to another location. There are even ultra-compact USB-powered models.

Most table fans allow you to adjust the force of the air moved using buttons or a rotating knob. And almost all of them are equipped with a protective mesh that completely covers the propeller on all sides. Although, of course, you can find simple models without a protective mesh at all.

Timberk table fan without grille, still stylish

Of the technical characteristics of desktop models, the most important are power and noise level. It is recommended to take a fan with a noise level no higher than 30 dB, although for some models the “permissible” noise level can reach 38 dB, that is, during operation the unit will happily “ride” your ears. It’s better to listen to the selected model before purchasing: often manufacturers indicate in the data sheets only the lower noise limit, which is valid for the slowest fan operating mode.

Many brands sell table fans in Russia, both good and Russian-Chinese: SUPRA, Rolsen, Timberk, Mystery, Vitek, Polaris, Bimatek, Stadler Form, Bork and others.

⇡ Bladeless fans

There are fans without blades at all. Bladeless fans from Dyson, for example, look futuristic, are completely safe, but cost a lot. At first it’s difficult to understand where the air comes from: it seems like it’s coming from nowhere. Here is a room, here is a table, here is a plastic ring - and out of nowhere on the other side of the ring there is a stream of air.

Dyson bladeless fans on a telescopic stand

It's actually quite simple. The Dyson Air Muliplier draws in air and distributes it around the perimeter of the ring, creating a low-pressure zone and drawing air into the ring. Air comes out under strong pressure from a gap around the perimeter of the ring, so thin that at first glance it is not visible.

This fan, which costs around $300, operates almost silently. By the way, this technology allows you to create not only round fans, but also in the form of other closed shapes - for example, a curved oval.

One form of bladeless fans

Why Dyson? Because James Dyson was the first to bring such a design to market. Various clones often look more modest; they are produced by SUPRA, Clever&Clean, Flextron, Orion, VES, Roward, Kitfort and others.

⇡ Floor fans

Advances in this area have gone well beyond the traditional “big screw on a stick with a tripod.”

The Kreolz floor fan is one of many with an old-fashioned look.

Floor fans are much larger than table fans and are also much more efficient. They are equipped (even the nameless Chinese ones) with a fairly powerful motor, and their blades are usually 1.5-3 times larger than those of a tabletop one. Such fans can operate in horizontal and vertical mode (if we talk about modern models) and, in addition, the location of the floor-standing model can be adjusted in height thanks to a telescopic “leg”. You can also adjust the angle of inclination, directing the air flow in the direction you need, and the speed.

Based on the type of blades, floor fans are divided into axial and radial: in the first case, the blade wheel rotates only in one plane, while radial fans have a rotor with curved blades, which allows air flow under pressure.

Stylish floor fan Bork

Both tabletop and floor-standing models have, among their technical characteristics, primarily power - which allows you to understand whether the power of the distilled air is enough to blow the entire room. And if in the case of table fans, which, for the most part, are products for individual use, this parameter cannot be called the most important, then floor-standing models usually blow the entire room, and it is precisely according to the volume of the room that you need to select a fan with the appropriate power. It is quite simple to calculate: you need to double the volume of the room and divide by the number of people in the room. We assign units of m3/h to the result obtained and look at a similar characteristic in the passport of the desired model.

But, despite everything, the “screw on a stick” is, of course, cheap compared to column fans. They are produced by a variety of Rolsen, Polaris, Vitek, Scarlett, Bork, Supra, Mystery, Saturn, Stadler Form and dozens of other brands and not quite brands. The price range for floor-standing models is very wide, from three hundred rubles for a mass-produced, almost nameless box on the shelf of a chain store with a very mediocre design and a completely unpredictable service life, to branded works of art in chrome, LEDs, with a control panel, which, however, they can also unpredictably work for no more than one season.

⇡ Column fans and other air distillation options

Such devices are a relatively new type of safety fan, the principle of which is that an electric motor operating at high speed (about one hundred thousand revolutions per minute) draws in ambient air through a narrow external slot, and then pushes it out at a speed of about 90 km /h. The engine speed usually changes smoothly using a built-in rheostat.

Model from Bork

In addition to the non-standard design, it should be mentioned that instead of conventional carbon brushes, such high-speed engines use brushes made of a magnetic alloy: this eliminates the formation of harmful coal dust.

Mystery column fan looks good too

So far, such ultra-modern devices are not very common, but everything has its time. More popular are wall-mounted fans, which are usually hung in the toilet, combining a small box with a ventilation shaft pipe. This is an exhaust type of fan.

Another type of fans can simply cool the air, but do not participate in the supply and exhaust circulation of the air flow. They can be seen in films and in inexpensive hotels in southern Europe: a fan hangs on the ceiling, usually combined with a chandelier, and looks like a screw without any protection that lazily rotates under the ceiling, scaring off flies and driving away dust. In general, they did not deserve a separate subtitle.

Dospel exhaust fan is suitable for bathrooms and toilets

Today, column fans are produced and sold by such brands as Vitek, Rolsen, Bork, Mystery, AEG, Ricci.

⇡ Modern bells and whistles

Today's fans, both tabletop and floor-standing, have more than just buttons on the body. Modern models are often equipped with remote controls that allow you to change the flow power from any corner of the room. Also, a modern fan can operate in automatic mode if it has a timer: you can set the required time interval, after which the device will turn itself off.

Fan with fumigator Globus

Other bells and whistles include built-in fumigators for protection against insects, or ionizers for air purification; The latter, by the way, are already equipped with everything possible: we recently wrote about humidifiers and air purifiers, which are also massively equipped with built-in “Chizhevsky chandeliers.”

Scarlett floor fan with sophisticated control panel

Some completely optional bells and whistles include an LCD display and a built-in electronic thermometer, the readings of which cannot be said to be very accurate, especially when the fan is running. Another not very necessary bells and whistles can be called “wind mode”: that is, when the fan blows the room not with a light stream of wind, but with “gusts”, simulating normal wind.

⇡ Column fan and split system in one bottle

Today on the market there are very original solutions for cooling rooms, sometimes combining the most unexpected technologies. Like, for example, the new Samsung Q9000, which looks like an ultra-modern gadget in the house, and at the same time functions as a home floor air conditioner, almost a split system.

Column air conditioner from Samsung

Its operating principle is not much different from a conventional column fan: there are three fans, they are located on a stand, similar to a floor-standing speaker, and rotate, providing air flow. Naturally, all this is adjustable: from the quiet operation of one fan at low speeds (at night, for example) to the operation of all three at maximum speed. Even the blades of the Q9000 are “aerodynamically shaped,” not counting the inverter compressor and filter, similar to the electrostatic “dust collectors” that we talked about earlier.

And again he

The ideal picture is spoiled by the presence of an outdoor unit, which is connected to this tower by a corresponding tube - because, despite all the unusualness of the indoor unit (mimicry of a column fan), it is an ordinary split system with filters. Albeit an unconventional one.

⇡ Monoblock air conditioner

We briefly touched on monoblocks in the previous article about split systems, and today we’ll talk about them in more detail. A monoblock air conditioner is an integrated device in a single housing, often mobile (on wheels), in which all structural elements are placed. The hot air coming out of the monoblock is discharged outside through a rather large 10-15 cm diameter socket. It is usually placed outside the door or window.

It is quite difficult to completely seal such a system; it is not always possible to do this, and in this case some of the hot air will inevitably return back; the efficiency of such a device will be far from ideal.

Monoblock air conditioner with a rigidly fixed heat sink tube

Such air conditioners, like split systems, can filter air, heat and cool it, dry or humidify it (some models have special water tanks for this). There are models with a remote control and various functional additions.

Monoblocks are usually designed for a smaller room area than split systems: the theoretical maximum does not exceed 40 m2. And their cost varies, depending on the power and space served, in the range from 10 to 50 thousand rubles.

The Chinese Hankei mobile air conditioner with remote control is very similar to an “adult” one.

In addition to modern monoblock systems with relative mobility, memories of window monoblock air conditioners have reached us from Soviet times and old films: they liked to be installed in the windows of all kinds of government institutions, and all the elements in them were placed in a single housing. From this point of view, they are convenient, quite affordable and easy to install - and that’s where their advantages end.

Such air conditioners today have more disadvantages than advantages: few people would want to block the window. On the other hand, today's monoblock window units can be integrated directly into the wall. True, in this case it should be no thicker than 30 cm, and a huge hole will have to be made in it, having received permission from the relevant authorities.

Window air conditioner Jax

In a word, all this archaic stuff is more suitable for a dacha, although they are not exactly expensive, especially compared to their more modern counterparts; prices for a few models start from 4 thousand rubles. These models are produced by different brands. Window air conditioners are offered by General Climate, TCL, Daewoo, Hisense, Timberk, Chigo, Gree, and GoldStar (not the ex-LG one). Indoor monoblocks are produced by Electrolux, Ballu, General Climate, Zanussi, Dantex and Carrier.

⇡ Conclusion

Of course, there are also very exotic cooling devices, such as a pillow with self-regenerating cooling crystals, or a shirt with a fan - but this is rather a one-off product for those who like exotic things. We hope that our publication today will help you to some extent navigate your choice and avoid the negativity of the grueling summer heat. Cheers!

When the heat comes, not everyone has enough money or the opportunity to install an air conditioner in their apartment or house.

Moreover, even if you have installed it, as a rule, it only cools one room well. What to do with the rest? Should I buy more and install two or three pieces?

Therefore, most of us begin to look towards a cheaper and more common solution - floor fans. Such devices should be in every apartment, even those who already have a full-fledged split system.

Does the fan cool the air?

Although it’s worth reminding for those who don’t know - fans actually don’t cool the air at all, but simply move it back and forth around the room.

So what causes the cold to be felt? Everything is arranged quite simply. Your body reacts to heat by sweating profusely. Drops of moisture appear on the surface of the skin.

When they evaporate, excess heat is taken away. And an outside breath actually helps speed up this process.

Especially if the air is dry and not humidified by any special devices.

By the way, don’t be surprised, but sometimes it happens that the fan does not cool at all, and even performs the opposite function.

For example, if you place two ice creams on a stick, one of which will melt naturally, and a fan is directed at the other, then, strangely enough, the second one will melt faster.

This is explained by the fact that a layer of cold forms around the sweet delicacy, which in some way inhibits its melting. And when you direct a fan here, this layer is completely blown away. And the ice cream melts more intensely.

What practical conclusion can be drawn from this? Since fans are not sources of cold, it is more difficult to catch a cold from them than from traditional split systems.

Which floor fans should you choose for your apartment or home, and how to avoid the most common mistakes when purchasing so that the device can work for you for a long time and safely?

Fire safety

Let's start with the most important thing - fire and electrical safety. Do not forget that any fan is an electrical device.

One careless move or accidental short circuit, and instead of cooling the apartment, you can burn it down. And not every one of you has special spark-proof devices that can easily prevent such accidents at the initial stage.

If the wiring shorts to the housing from the inside, it may well shock you. Therefore, you should not move the wind blower from place to place while it is on.

Also pay attention to the material of the case. On the one hand, solid metal is b O Greater fire safety, but in terms of electrical safety, plastic looks more advantageous.

It is true that it is desirable that it be non-flammable. Check this in the product passport.

Also, be sure to look in the documentation for an indication that the engine has overheating protection. This could be a miniature thermal relay that breaks the circuit when the temperature of the windings reaches over 145 degrees.

At this point, the impeller stops and the engine will not start again until the temperature drops. Without such protection, this is a real fire hazard.

Expensive or cheap - what's the difference?

If you think that by purchasing the most expensive model you will get the best cooling, then you are deeply mistaken. To do this, it is not at all necessary to choose the fan with the highest price tag.

Often, even inexpensive models cope with their tasks very well. Let's visually compare the efficiency of three wind blowers in different price categories:

Cheap models are usually the flimsiest and most unstable. Their noise level at maximum speed reaches 70 dB.

The blowing speed here is 4.9 m/s

The middle version does everything the same, but the only thing added to it is a timer and remote control.

True, its design is more stable, and the material used is of better quality. This affects the weight of the device.

At the same time, the noise level here is still the same 70 dB.

And don’t be surprised, with more expensive models it is quite possible that the air flow will be less powerful than with their inexpensive counterparts.

As for sophisticated models at inflated prices, on the one hand they seem to be heavier and, accordingly, more stable. And silent mode is really the quietest (less than 50dB).

However, at maximum speed, which is most often used in the heat, the results are still the same as those of cheap competitors. The noise reaches 70db.

Their blowing power is only a few tenths higher - 5.6 m/s.

So it turns out that there isn’t much of a fundamental difference in performance between models for 800 rubles and 5,000 rubles.

All the convenience lies only in additional controls and maintenance.

It's up to you to decide whether it's worth paying extra for it.

Foundation stability

Fan stability is the most important factor. If there are children or pets in the family, they can somehow touch the wind blower stand.

And if it falls, many problems can arise. It all depends on where exactly it will fall.

By the way, even a new fan often fails after the first overturn. Read what breaks and how to fix it yourself in a separate article.

There is a huge variety of base designs on which the stand is mounted. But only three are the most common.

The most common type is a cross-shaped base.

Less common is the round stand.

There are also fans of the monoblock type. They don't have any legs at all.

Which of these bases is the most stable? The cross-shaped base, despite its external reliability, is inferior to everyone else.

One good push is enough and such a fan will calmly fall on its side. But the round leg is the most stable option.

Therefore, if you have a choice, then give preference to the round shape.

Performance

Many people still confuse fan power and performance. Although these quantities have little relationship with each other.

Most home models range from 40 to 60W. This parameter indicates how much electricity your unit consumes per hour. And this only indirectly affects productivity.

The larger the motor, the longer and wider its blades. Their maximum diameter in home floor types reaches 40 cm.

Fan performance directly refers to the volume of air moved per unit of time. How to determine what performance you need?

To do this, calculate the volume of the room being blown, that is, multiply its area by the height of the ceilings.

After this, substitute the exchange coefficient into the formula. Its meanings are as follows:

• for residential premises – 3

• for kitchen and bathroom with toilet – 15

The formula for calculating the required fan performance is L=S*H*k

• S-area

• H-ceiling height

• k-factor

That is, if your bedroom is 18m2 with a ceiling of 3m, then it will require a fan with minimum performance - 18m2*3m*3=162m3/h

For example, models with a power of 20W can easily blow air into rooms with a volume of up to 200 cubic meters.

Unfortunately, most manufacturers do not list performance parameters in their documentation. How to choose a wind blower without knowing its size?

Focus on those units that have a higher number of speeds. For small kitchen or bedroom spaces, only two airflow modes will be sufficient.

And for huge rooms of more than 20 m2, you will need three or all five. The higher the speed, the more air the unit will move in the same unit of time.

The size and number of blades also influence performance. The most common models are:

What's the difference between them? The larger and wider they are, the further they throw the air flow. Therefore, wide impellers, with the same engine power, should be given preference.

What about the quantity? Of course, for fans of the same power and impeller width, those with a larger number of blades will be more productive.

However, they will still lose out to their wider counterparts. Therefore, when choosing, first of all, focus not on quantity, but on width.

An ideal fan model should operate with a noise level of up to 30 dB. It's like a whisper or the rhythmic ticking of a wall clock. True, this is achieved at the very minimum speed.

So that you understand, for comparison, the refrigerator during operation has a sound within the range of 38-42 dB.

As you know, extraneous noise tends to layer on top of each other. The operating noise of all household appliances in the apartment can reach up to 90 dB. And this is similar to a passing train a hundred meters from your house.

This volume is very harmful to the health of young children. Until 2 years old, they cannot distinguish what is extraneous noise and what is the necessary sounds for learning.

Therefore, over time, such children become irritable and nervous. And your constantly on fan will only contribute to this.

In order to protect the health of children and your nerves, it is very important to have a quietly operating fan. And here again, models with wide plastic blades and a minimum number of them win. Your children will only thank you for choosing such a fan.

They have the lowest performance when actually measured with special instruments.

Protective grille

Today this accessory is a mandatory attribute of any floor fan with moving blades. However, even if it exists, this does not mean good protection.

Little curious children love to stick their fingers anywhere while exploring the world around them. And it can be not only sockets.

Therefore, if we are talking about the complete safety of fans, then your choice should be towards those types that are equipped with grilles with the narrowest and smallest cells.

Right in the store, try to see if your little finger can fit through the bars to make sure your purchase is safe in advance.

Because even models with plastic impellers can break the delicate fingers of small children.

Not so long ago, fans appeared without external blades at all. The so-called Dyson fan.

How does it work and inflate the air? At the base of the device there is a turbine that takes in ambient air and accelerates it.

As a result, it flies out in a certain direction from the slots around the circumference of the frame.

Such devices combine simultaneously:

It would seem that this is the most ideal fan. No external rotating parts, many functions, plus compactness and beautiful appearance.

However, everything is spoiled by the price of the issue. On high-performance models it reaches such a level that it is much more profitable to purchase an air conditioner.

Well, in the end, we’ll look at a few exotic and unusual fan options. For example, the most expensive and gigantic wind turbine built by engineers in Florida.

It is used to check how a building can withstand hurricane winds. It consists of 12 turbines with a power of 700 hp. each.

Such a giant can create an artificial air flow at speeds of up to 250 km/h! The famous Hurricane Katrina had the same power.

There are also completely portable and original options - a baseball cap with a propeller on solar panels.

Or a pocket fan powered by USB and also battery operated.

However, there is no benefit from such gadgets. It's more of a toy accessory for entertainment.

Unless models connected via USB can be conveniently plugged into a laptop and get at least some coolness directly at your workplace.

Errors in selection

To summarize all of the above, we summarize the most common mistakes that should be avoided when going to the store to buy a fan.

One of the pressing problems of humanity is global warming. Every year it gets hotter outside. Many people bought air conditioners a long time ago, while others have to rely on other methods of cooling. In this case, a floor fan with cooling can be a good and budget solution. In the article we will look at what it is, types, method of action and reviews.

What kind of device is this?

A fan with humidifier is a device equipped with This improvement makes the air cooler due to increased humidification.

In the summer, the indoor atmosphere becomes especially dry. For people whose blood pressure rises and the mucous membranes of their eyes and nose dry out, such a floor fan with cooling is simply a lifesaver.

It is possible and even necessary to use such devices in children's rooms, clinics, warehouses, agricultural areas, exhibition halls, discos and gyms.

Advantages of the device

Each person chooses for himself which fan is better and more suitable for the intended purposes.

A household appliance with a humidifier has characteristics similar to conventional fans:

• built-in automatic timer;
• adjustable tilt level;
• presence of a remote control;
• economical energy consumption.
• small size, easy to move, equipped with a stand with wheels.

And also unique advantages:

• large and convenient water tank;
• the presence of a self-shutdown function if the water in the tank runs out;
• easy installation and use;
• gentle temperature control while maintaining the required humidity;
• can serve as a good alternative to an aroma lamp, you just need to add essential oil to a container of water;
• low cost;
• Possibility of use in open areas;
• The device is mobile and lightweight, which allows you to move it to any place.

Types of devices

Floor-mounted household cooling fans can be divided into several types, depending on the humidification method:

1. Traditional fan. The device is equipped with a paper filter that can be replaced if necessary. Air particles pass through it, are filled with water and then enter the room. This type of fan effectively removes smoke and odors through filtration.
2. Steam fan. The device humidifies the air by heating the water to the maximum for its further evaporation. This fan can raise the humidity in a room to 60%.
3. Ultrasonic fan. It is based on a plate that vibrates at a high frequency. As soon as the water touches it, it breaks into small particles and becomes a cloud of cool water vapor.

Each type of fan has its own advantages and disadvantages. They must be carefully studied before purchasing.

What to look for when choosing?

When deciding to purchase a floor fan with cooling and humidification, you should pay attention to the following characteristics:

• Device power. For a room of about 20 m2, a fan with a power of up to 100 W is suitable, and for use in large areas (with an area of ​​more than 35 m2), devices with a power of more than
• The size of the blades and the presence of a protective grille. You also need to pay attention to these parameters. The blades provide speed and therefore cooling rate. If there are children or animals in the room, the grille will protect the games.
• The size of the water tank. The more liquid that fits in the container, the longer the device can work.
• The number of modes, the presence of a timer and control panel, the angle of inclination and the ability to rotate the fan. Additional characteristics also require attention. They will ensure more comfortable use of the device.
• Do not forget about the noise of the device during operation. The higher the power, the louder it will run.

When purchasing a device, you should also take into account that this is a floor-standing device, and therefore you should choose it taking into account the availability of free space and the area of ​​the room.

To use a cooling floor fan effectively, it pays to listen to the advice of experts. They recommend:

1. To quickly lower the room temperature, you can add ice to the water.
2. Filling the tank with purified or distilled water will extend the life of the fan. Regular tap liquid will quickly contaminate the filter and leave a residue on the device.
3. It is allowed to add aromatic oils to the tank, but if the fan does not have an ionization function. This action will provide a pleasant smell in the room throughout the day.
4. A fan with an air humidifier can be used to combat midges, mosquitoes and other unpleasant creatures. You just need to add a little repellent to the water tank.

Such floor fans can successfully replace expensive air conditioners. They have become a salvation for people who cannot tolerate heat and dry air in the house.

Devices with fan power up to 65 W

The most popular floor cooling fans are the multifunctional air conditioners SeaBreeze SB-535, UFO ATSFI-01 and RICCI HYD-006.

These are floor-standing paddle devices with the following characteristics (see table below):

SeaBreeze has a stylish design, stepped speed switching, backlit keys, electronic controls and an LCD display.

The RICCI HYD-006 radial fan can add two cooling batteries to make the space cooler. There is filtration and purification of incoming air.

Air humidification in a ventilated room reaches sixty-five percent, which is the optimal indicator for the human body.

Devices with a fan power of 70 W or more

The most popular models of this power are the Vitta GX-31G, VES MS 402 and Mist Fan LB-FS-A fans .

These devices can be compared according to the following parameters, as indicated in the table in the photo below:

The VES device can be adjusted in height and has an ambient air ionization function. In addition, if you disconnect the tube, this device can be used as a simple humidifier without venting.

All models are safe to use and can automatically turn off if overheated or tilted (if dropped).

Axial fans are what are popularly called “daisies”. The motor drives the blades, which are fixed to an axis and hidden under a mesh for safety purposes. The more powerful the motor, the longer and wider the blades themselves, and the higher the fan’s performance - the volume of air it can move in an hour.

The design of a radial fan is a pipe or cylinder with many blades that drive air in a circle (radius) inside the cylinder, and it is pushed outward under the influence of centrifugal force. If an axial fan simply moves air, then a radial fan creates pressure and directed flow. Radial fans are usually column-type, and the column can be either tall or very small - there are also portable fans with handles.

Column type fan

Tabletop or floor-standing?

Floor fans with a leg have more options in terms of blowing direction: as a rule, they rotate the “daisy” with blades to the right and left, and the user can adjust its inclination and the height of the leg. Table and floor axial fans often cannot turn, especially retro-style designer models, when a ring with blades is enclosed between decorative supports. Table fans sometimes have mounts for wall mounting. Judging by the reviews, this often comes as a surprise to buyers: it blows great, but only in one direction. Column fans, as a rule, are able to rotate the housing in different directions.

Retro Table Fans

Or maybe ceiling?

Ceiling axial fans are more likely associated with government premises - dining rooms, foyers in a holiday home somewhere in Kislovodsk. But in principle, they belong to household fans and can easily be installed in any room in the house. The advantage of a ceiling fan is the uniformity of airflow and the absence of danger that as a result of its operation you will be blown out. Ceiling fans have longer blades and powerful motors, they are more efficient, and, by the way, they are not cheap. Ceiling fan manufacturers claim that they are a true alternative to air conditioning, but with no refrigerant, no filters to replace, and use much less electricity. Let me doubt it: air conditioners cool the air, but they can also work to heat the air; an air conditioner can lower the air temperature by 10, 15 and even 20 degrees, and fans create the feeling of a lower temperature.

Innovation of the last decade: bladeless fans

The “pioneer” here was the Dyson company, which made a turbine built into the body, which pumps air from the room and releases it outside through an oval frame, multiplying its speed. The main advantage is that a child or animal will not reach the blades. These fans are also easier to care for - dust does not stick to the grilles and blades. But the pleasure is very expensive.

There are no other bladeless fans on the Russian market yet, but they are made in the world; you can buy such a craft (or fake) much cheaper, but no one will give a guarantee of quality.

Power and Performance

Table fans have a low power - 20–30 W, floor fans - 40–100 W. In addition, the maximum power consumption may depend on the presence of additional functions (heating, humidification).

When buying a fan, performance indicators (so many liters of air per hour) will not tell you anything: it is difficult to imagine these liters of air. Therefore, it is better to look at the area of ​​the room for which the device is designed.

Floor axial fan

Noise level

The noise level is important for comfort. For comparison: the noise level of a refrigerator with the compressor on is 38–42 dBa, and you will hardly hear 38–39, 41–42 can interfere with sleep. The maximum noise level of 45–50 dBa is not terrible; if the fan has low operating speeds, it will make less noise at them. Ideally, you need to listen, otherwise, when installing it in the bedroom, you may be in for an unpleasant surprise.

Control

The simplest models have mechanical control and two or three operating speeds. For the more advanced, it is electronic, often touch. It is convenient when the fan has a remote control, which can be used to enable or disable the housing rotation function, select the speed and direction of the blowing.

Electronically controlled fan with remote control

As a rule, such models also have a display that displays all operating parameters and sometimes the room temperature. The most modern models allow you not only to regulate the speed of operation, but also to program the operation of the device at different times of the day or by day of the week, and use a timer. There are fans with remote control via a smartphone application. If you buy a model with electronic control, then look for an auto-shut-off function or a shutdown timer: this is useful; people often forget to turn off the fan.

Fan with remote control REDMOND SkyFan 5005S

overheat protection

It makes sense to read the user manual for the model you like, fortunately, now you can find almost anything on the Internet. There will definitely be information about whether the motor is protected from overheating: after all, in hot weather the fan works almost around the clock, and it is important that the motor can be switched off (so that the electrical circuit opens at temperatures above a critical level). Otherwise, the motor may simply burn out.

Additional functions

The most common “bun” is operation in fan heater mode. If you need a “2-in-1” device, then it makes sense to buy a fan heater that can operate without heating, in the mode of a regular fan.

Some models can humidify the air - in fact, these are ultrasonic humidifiers connected to blades: water “mist” is generated by ultrasonic vibrations, then rises through a hose to a block with blades and spreads throughout the room using a fan. The downside is that they require the use of softened water, otherwise a white coating from salts, which are contained in tiny drops of water blown by a fan, will form on surfaces and furniture over time.

Many residents of apartment buildings faced the problem of cooling their homes in the hot summer. As a rule, residents who can afford it install expensive air conditioners that effectively cool the apartment. However, there are other equally effective ways to cool rooms using affordable fans. In this article we will take a closer look at how you can cool your apartment and your room using a fan without significant costs and create a favorable microclimate in your house or apartment during the hot season.

Method 1

There are several most effective methods that allow you to quickly reduce the room temperature to a more comfortable one.

We need a bowl of cold water, a floor fan, a plastic bottle of frozen water and a piece of gauze.

Take gauze and thoroughly wet it in cold water. After this, you need to throw moistened gauze over the fan. To do this, lower any of the 4 ends of the gauze into a bowl of cold water, which will stand next to the fan. After this, turn on the fan, and the room air, together with circulation, will begin to cool the room. To achieve maximum effect, place a plastic bottle with ice or very cold water in a basin. Depending on the fan diameter and installation height, you will need to select the gauze size.

Method 2

We offer you another effective method that will help answer the question - how to cool yourself and a room without air conditioning? For this we need a floor fan and a large container for water. It is best to use cool water, and the larger the container for it, the faster the room will cool. We install the fan in the required position and place a container of water in front of it. In the process of intensive blowing of warm air into the room, the water will begin to evaporate. And thus the temperature in the room will drop by 2-5 degrees.

Method 3

Using a floor fan, you can effectively cool rooms in the evening or at night. To do this, you need to turn the fan in the direction of the window. This will allow hot air to escape from the rooms. In other rooms, all windows will need to be opened completely. In this case, a draft results when the influx of fresh air from the street pushes hot air out with the help of a fan. Thanks to this, the indoor temperature will be equal to the cooler outdoor temperature.

Method 4

For this we need a floor fan and empty 1.5-2 liter plastic bottles. Pour cool water into plastic bottles and freeze. After that, we place bottles of frozen water in each room. We install a floor fan in the living room, which will cool the room more efficiently. When the water has melted, you should put the plastic bottles back in the freezer and repeat the procedure again.

Tip 1

To keep your rooms cool and fresh, you should wet clean all rooms as often as possible. As a rule, it is best to perform wet cleaning with cold water in the early morning, when the rooms have not yet warmed up.

Tip 2

Curtains in rooms can be wetted with clean, cool water. This equally effective method allows you to reduce the temperature in the premises. To do this, you need to use a regular sprayer or otherwise spray cold water on the curtains. In extreme heat, it is best to repeat the procedure as often as possible.

Tip 3

Cover the windows with reflective film. In sunny rooms, it is necessary to stick reflective films on all windows, which will protect the rooms from direct sunlight. Thus, the temperature in the rooms will remain favorable for a long time.
