How to escape from the heat without air conditioning? Can a fan replace a ventilation grill Is it worth putting a fan in a bathroom

It is installed in order to organize air exchange. Any residential building / complex is equipped with ventilation shafts, which are rarely serviced by craftsmen and often do not cope with their task. The bathroom differs from the rest in high humidity, the accumulation of various odors and small dimensions. Therefore, to the question “should I put a fan in the bathroom?”, The answer is yes.

This extractor will provide:

• Quality ventilation.
• Eliminates unwanted odors and excess moisture.
• Temperature regulation.

Exhaust air contains dust particles, viruses, harmful vapors, carbon dioxide. In addition, the temperature in the room is always higher. All this negatively affects the well-being, human health and the preservation of a normal microclimate.

Do I need an extractor hood in the bathroom if there is a window

In this case, the answer will also be positive - it is definitely needed. The principle of operation of the ventilation system in any room is the outflow of exhaust air masses and the subsequent inflow of fresh air from outside (i.e. from the street).

With natural ventilation, the inflow is carried out through open windows, doors, through leaks / cracks, and the air exhaust is provided by natural draft (through ventilation shafts). Therefore, if the bathroom has a window, this will not ensure the removal of exhaust air masses in full. In addition, in winter period the air and temperature outside will not allow you to open windows often.

Should I put a fan in the bathroom

If dampness, condensation occurs, and also if there is a toilet in the bathroom, an exhaust fan is a must. Its advantages:

• The device will eliminate unnecessary odors from this room, humid air, therefore, there will be no traces of dampness (mold, fungus, rust).
• A working extractor hood will improve air circulation throughout the home.
• The bathroom will always have fresh and clean air.

Is it possible to put a fan in the bathroom and which one

All air circulation devices are differentiated from each other. Accordingly, there are models of exhaust fans that are designed for installation in bathrooms. They are distinguished by increased protection against water, high performance, noiselessness and the presence of various options, including sensors, timers, cord switches, etc. The shape and design of the device are also variable.

Purchasing a bathroom extractor fan is easy. For this, the necessary technical specifications device:

• Noise level. Most models have a standard noise level. There are devices whose operation is almost silent.
• Performance. How to choose bathroom fans, given this criterion? Everything is very simple: for this you need to calculate the volume of the room and multiply this value by the rate of air change (7-9 for the bathroom). The result is a figure that indicates the desired performance of the device.
• The presence of automatic blinds, a hygrostat, motion and light sensors, a timer - all these options allow you to use the device with increased comfort and economy.

Also, the exhaust fan can operate at several speeds with its smooth regulation.

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

Method 1

There are several most operating methods, which allow you to quickly bring down the temperature in the room to a more comfortable one.

We need a basin cold water, a floor fan, a plastic bottle with frozen water and a flap of gauze.

We take gauze and carefully moisten in cold water. After that, it is necessary to throw the moistened gauze on the fan. To do this, any of the 4 ends of the gauze should be lowered into a bowl of cold water, which will stand next to the fan. Then turn on the fan and room air together with the circulation will begin to cool the room. To achieve maximum effect, put a plastic bottle with ice or very cold water in a basin. Depending on the diameter of the fan and the height of the installation, it will be necessary to select the size of the gauze.

Method 2

We offer you another effective method, which will help answer the question - how to cool yourself and the room without air conditioning? To do this, we need a floor fan and a large water tank. 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 put a container of water in front of it. In the process of intense 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

With the help of a floor fan, you can effectively cool the premises in the evening or at night. To do this, turn the fan in the direction of the window. Thus, hot air will come out of the rooms. In other rooms it will be necessary to open all the windows completely. In this case, a draft is obtained when the influx of fresh air from the street will push hot air out with the help of a fan. Due to this, the temperature in the rooms will be equal to the cooler street.

Method 4

To do this, we need a floor fan and empty plastic bottles for 1.5-2 liters. Pour cold water into plastic bottles and freeze. After that, we arrange bottles of frozen water in each room. In the living room, we install a floor fan that will cool the room more efficiently. When the water has melted, you should put the plastic bottles back into the freezer and repeat the procedure again.

Tip 1

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

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, it is necessary to spray cold water on the curtains using a conventional sprayer or in another way. In extreme heat, it is best to repeat the procedure as often as possible.

Not everyone today can afford the installation of a full-fledged air conditioner. Meanwhile, the heat in summer reaches such exhausting heights that it is unlikely to survive without specialized equipment.

Buying a fan is optimal solution, which will suit both the price and the quality of work. In addition, you can make an impromptu air conditioner from a household fan!

Fan wear: how to avoid premature failure?

The bottom line is this. The fan rotates thanks to the shaft of the electric motor, on which it is mounted. Therefore, there are only two weak points in this design:

• fan impeller shaft;
• windings of an electric motor.

In the hottest months of summer, the fan operates around the clock and many users are afraid for the equipment - will it withstand such a pace of work? Consideration should also be given to the manufacturer and the materials that were used.

Chinese manufacturers achieve the highest possible cost through the use of disgusting plastics. Over time, they lose their density and become soft, especially if direct sunlight falls on it.

However, if carried out regularly Maintenance fan, it will last a long time without creating any problems?

How is the fan serviced?

The shaft on the fan must be in a rigid hitch. Over time, constant air pressure will be applied to the plastic. Eventually, the shaft in the impeller will begin to slip.

This can be heard by the sound of the fan.

To fix the indicated problem, a few drops of superglue will be enough. With overheating of the windings, everything is much more complicated. When it comes to an air-cooled electric motor, it should be especially efficient in summer.

In general, no one forbids the operation of household fans for several days in a row. But do not forget that they are very "gluttonous consumers" of electricity.

This must be taken into account when creating a comfortable indoor environment.

The specialist will tell you how to choose the right domestic fan:

The presence of high humidity in the kitchen or in the bathroom says only one thing - there are difficulties with ventilation of the premises, the cause of which is poorly functioning natural ventilation. This problem can be solved by installing an exhaust fan.

The principle of operation of natural ventilation, traditionally used in most houses and apartments, is the difference in the density of internal - warm and external - cold air, formed in vertical ventilation ducts. But this scheme comes into action only on the condition that there is access to fresh air in the place taken away, for which additional entrance openings in houses are intended. A decrease or increase in the intensity of ventilation can only be corrected by adjusting the damper of these openings. However, if even in the case of a sufficient opening of the ventilation grill, natural ventilation is clearly not enough (too stuffy and there is nothing to breathe), then only ventilation remains by regularly opening windows.

Of course, ventilation is not always perfect, but the accusations of defectiveness are not always justified. First of all, it is worth making sure that the veterinary ducts are clean and passable, since often, over time, during long-term operation, the web formed and the debris that has got there clog the ventilation passages to a greater or lesser extent, which, accordingly, becomes an obstacle to ventilation of the premises. The second reason for poor natural ventilation is a dirty mesh ventilation grille.

Manufacturers of ventilation grilles supply them with plastic nets that protect the apartment from the penetration of insects from the outside. The absence of an extractor hood in the kitchen or its insufficiently good functionality contributes to the rapid accumulation of fat droplets on the cells of the plastic grid, which, accordingly, leads to their narrowing. The grid gradually turns into a kind of damper, dense and absolutely impenetrable, which is the source of the problem. Usually it is enough to change the old mesh to a new one so that the difficulty with high humidity is eliminated, but the mesh filled with fatty deposits is nothing more than the result of unsatisfactory and weak operation of the hood grease trap, and this problem also needs to be addressed.

As previously stated, the rooms most prone to high humidity in the apartment are the bathroom, bathroom and kitchen. Therefore, structurally, ventilation in houses and apartments is designed so that the ventilation openings are located in these rooms. To get into the vent, the air must pass through several zones through the gaps at the base of the doors or through specially designed grilles.

In cottages and private houses, the ventilation system may include exhaust openings, including in saunas, indoor pools, boiler rooms, dressing rooms and storerooms. Due to the direction of air to the premises - the sources of the greatest humidity and odors, the air in residential areas almost always remains fresh and clean.

Unfortunately, natural ventilation is not always able to cope with its task. Its functioning is affected not only by the size of the inlets, but also by the direction of the wind, its strength, the placement of adjacent high-rise buildings and other equally important factors. The most undesirable and unpleasant consequence of poorly functioning ventilation is too much humidity, which is the cause of mold and mildew on walls and ceilings. Many try fungicides in this case, which in itself does not eliminate the causes of the phenomenon and does not stop the process.

Experts advise not to hesitate to identify the source of poor ventilation when high humidity and a characteristic smell of dampness appear. If the complication is caused by insufficient draft in the ventilation ducts, in this situation they will come to the rescue wall fans small size, which are installed to replace the ventilation grille. It does not take long for them to eliminate a significant amount of used air, ensuring sufficient room air exchange.

How to choose and install an exhaust fan

Before buying a fan, you need to measure the ventilation holes. Often they are squares with a side of 14 cm, although sometimes rounded holes with a diameter of 15 cm come across. It is extremely important that the fan has a cover that covers the vent, while the diameter of the impeller should be slightly smaller. The performance of exhaust fans, sometimes found on sale, which can be mounted in ventilation holes with a diameter of only 10 cm, is clearly insufficient for high-quality air exchange either in the bathroom or in the kitchen.

The productivity of exhaust fans should correspond to 100 m3/h. There is a certain pattern: the increase in productivity leads to a faster removal of polluted air, which, accordingly, increases the noise level and leads to more energy consumption.

As for the noise. Absolutely any working fan is a source of characteristic sounds, which are also transmitted through veterinary channels. In addition, the turned on fan at the same time becomes a source of vibration transmitted along the walls. Therefore, if there is an assumption that the neighbors will be unhappy with the presence of a source of annoying sounds and vibrations installed in the kitchen or in the bathroom, it is better to look at its quietest model in advance, although such modifications are somewhat more expensive than usual ones. Often, the design provides for the presence of a ventilation hole directly next to the shower. Here, the solution to the problem will be the choice of a waterproof model that does not work from 220v, but only from 12v. It is important to remember that the installation of an exhaust fan reduces natural ventilation to almost nothing, since the outlet is almost completely blocked by the impeller, and this, accordingly, is an indicator of the need for periodic operation of the fan.

Usually it is connected together with the lighting of the bathroom, which is very convenient and uncomplicated: the air is removed directly at the moment of pollution. The lighting goes out - it stops working. This method, which is appropriate for the bathroom, is not suitable, for example, in the version with a kitchen where there is no need for constant lighting. But here, too, there is a way to solve this problem - the operation of the fan will help to extend the relay with a delayed shutdown.

The only thing that is not very pleasant when installing an exhaust fan is damage to the wall or ceiling finish, since it is necessary to lead the wire to the vent. The option of decorating it in a special plastic box will not be very successful - not too aesthetically pleasing and unattractive. In order to avoid these difficulties, you can purchase a fan with built-in photocells that are sensitive to the inclusion of light. During installation, they do not need to be combined with lighting switches. The cost of these models ranges from 1,500 to 2,000 rubles.

In rooms where there are windows, the relationship between the fan and the light does not make sense, so each has its own switch. Another version of the model with a built-in switch on the cord is also possible, which is not very convenient, since it becomes necessary to remember to start it. In any case, whatever modification is chosen, it will become an obstacle to the occurrence of high humidity and, as a result, mold and mildew.

As an alternative, a motion sensor can be used, which gives a signal to start work if there are people in the room. It will be more convenient to purchase an air humidity sensor, although it is very expensive (2,700 rubles), but in this case, manual control is not needed.

It is not enough to choose a fan model, besides this, you need to determine exactly how it will be connected. It must be taken into account that fans on photocells, with humidity and motion sensors and cord switches are autonomous from other switches and only need to be connected to a junction box, which is their great advantage.

The process of installing an exhaust fan will not cause any particular difficulties, however, in the absence of experience in working with electricity, it is better to leave the connection to a professional. The fan can be installed in the hood hole by dismantling the ventilation grille and fixing the fan in the way provided by its model. An electric drill with a hammer drill is the maximum that is required.

And the last one is very important point- an exhaust fan cannot be installed in apartments where the ventilation system provides for common ventilation ducts. This is due to the fact that the fan, creating excess pressure in the ventilation passage, forcing the air to move upwards, in the event of several passages being connected, will also drive it to neighboring apartments.

Summer is characterized not only by the season holidays, trips to the sea or other bodies of water and summer holidays. This time of year is also accompanied by very warm, and sometimes unbearably hot weather. Many publications have been written about how harmful high air temperatures are for humans, so the desire of most people to make the microclimate in their home more or less comfortable in summer is understandable. Certainly, ideal option in this case, it is the installation of an air conditioner, but it is quite expensive and not everyone can afford it. Therefore, other methods of cooling the air in the house are quite in demand in the summer.

First, let's look at how cools down our body in hot weather. There are four methods of heat transfer from the skin to the environment - convection (transfer of heat to moving air), conduction (transfer of heat to still, cool air), evaporation (cooling by evaporation of sweat), and radiation (radiation by the body of infrared radiation). In everyday life, it is possible to use two methods - you can cool the air (which is the work of the air conditioner) or make it move and take heat from the body. Of course, you can also use evaporation, for example, douse yourself with water or take a cool shower, but these are temporary measures and do not affect the microclimate in the house. Therefore, in the absence of an air conditioner, it is necessary to increase the ventilation in the house, which will cause the air movement we need. However, it also needs to be done right.

by the most common household appliance, which is applied to create movement , is the fan. However, no matter how pleasant it is to sit under a stream of air from it in the summer heat, you still shouldn’t do it - such “blowing” is fraught with the occurrence of colds and a drop in immunity. It is better to place the fan in such a way that it causes a slight movement of air throughout the room, for example, put it in a corner and direct the airflow diagonally across the room. Of course, you can hardly achieve a quick feeling of coolness with this method, but in any case it will be more comfortable than on the street.

To move air were more tangible, you can use two fans - one blows air out into the street through the window, the second stands near the door or opposite the first at the other end of the room and drives the air in the same direction. This direction of ventilation is used in the daytime, when the outdoor temperature is much higher than the room temperature. In the evening or morning coolness, you can change direction or simply turn off the fans - cool air will enter the room itself. Moreover, even in the absence of fans, according to the same principle, it is worth airing the rooms in the summer - open the windows in the morning and evening or at night and close them tightly during the day - a sluggish draft from the window will not save you from the heat, but will only additionally heat the air in the room.

Main open windows at least at some time of the day for ventilation - in the hot time of the day in apartment buildings practically does not work, which leads to poor air exchange and the accumulation of respiratory products in the apartment. The use of special small fans that are installed in the vent, or at least the inclusion of a conventional kitchen hood for a couple of hours a day, will help to partially correct this situation.

Use fan can be done more efficiently even with the windows closed, forcing it to "drive" cooled air. To do this, behind the fan blades, you can install or put several containers of refrigerant, which are placed in cooler bags and are widely available. If these are not available, bottles of frozen water can be used to cool the air. Hanging wet towels around the house or apartment, contrary to popular belief, is ineffective - for at least a little noticeable cooling of the air, it is necessary to hang them all over the room. The same can be attributed to the recommendations to spray cold water from a spray bottle - this will give a temporary, very short effect. In addition, with the windows completely closed, this will cause a significant increase in humidity in the house, which can negatively affect furniture and coatings, and can also be a provoking factor for diseases such as bronchial asthma.

Of course, all these methods will not create the same comfort in the apartment as using air conditioner, however, proper ventilation of the house when high temperature air will create the necessary movement, which will greatly contribute to the removal of heat from the human body and will make it possible to more or less painlessly survive the hot season.
