Mixing fresh air with air conditioning. The main functions and modes of operation of Split air conditioners with forced ventilation

Often after installing a metal plastic windows there are problems with the ventilation of the room. This leads to an increase in the concentration of carbon dioxide in the room. The level of humidity rises in the apartment. Residents begin to feel unwell, there is a feeling of constant drowsiness and other backfire. What can be done to put everything back on track? There are several basic options, and one of them is air conditioners for an apartment with forced ventilation. They allow you to simultaneously create comfortable living conditions (temperature, humidity) and saturate the room with oxygen.

In addition, you can use the option with the restoration of air flow without the use of equipment. To do this, you will need to use all kinds of valves.

Ways to establish natural ventilation

First, let's check if the hood works in the apartment. During the diagnosis, you should open all the windows in the apartment and bring a piece of paper to the vent. If it sticks to it, then everything is fine with the hood.

Checking traction

Now let's check if fresh air enters the apartment. To do this, you will need to close all windows and entrance doors. Then do the same operation as before. If the sheet did not stick to the vent, then the ventilation was disturbed precisely because of the installation of new sealed windows.

How to restore natural flow?

Direct inlet valve

Cheapest, but less efficient and functional way make an influx fresh air in the apartment, there will be a restoration of natural draft.

There are several main options here:

• Embed in structure plastic windows supply valve. It includes an air filter and a noise absorber. This will block the path of dust and sounds from the street to the apartment.
• Do periodic ventilation. But in this case, in winter, too much heat will escape from the apartment, and noise and dust from the street will freely enter the room.
• The best option to restore the flow is to install a wall inlet valve. He will allow the right amount run clean air into the apartment. Experts recommend installing a valve above the radiator, which guarantees the entry of heated air masses into the apartment.

Window inlet valve

Two in one - air conditioning and ventilation

Nowadays, one of the popular solutions to the issue of ventilation after the installation of metal-plastic windows has become air-conditioned air conditioners. They are able to perform two functions simultaneously: to create optimal conditions for living, that is, they allow you to regulate the air temperature and humidity level, and saturate the room with fresh air, which will significantly improve the well-being of residents.

What are the principles of work?

indoor unit

A split system needs two main blocks:

• Interior;
• Outer.

The first includes an air filter, control panel, fan, and more. AT outdoor unit includes compressor and automation.

Where would be the best place to place the modules?

The indoor unit is often installed on the balcony. It does not take up much space, it works quietly, which has a positive effect on comfort. It is also possible to install a wall-mounted split system for false ceiling. The equipment is made in such a way that it does not harm the interior of the apartment in the slightest. Only decorative ventilation grilles will be visible to the eye.

The outdoor unit is mounted from the side of the street. Using a thin freon tube, it is connected to the inside of the ventilation. A heater is also connected to the indoor unit.

outdoor unit

The work is done in the following way. First, the air is taken from the street, then it passes through the channel into the mixing chamber. In the indoor unit, the air is filtered, heated or cooled and supplied to the room.

microprocessor control

This is a kind of brain of the entire split system with ventilation. Thanks to electronic system control, the operating modes of the air conditioner will change depending on the changing weather conditions.

A smart air conditioner in autumn and spring will not immediately turn on heaters to heat the air. He will use the heat pump", which will save on electricity. A lot of modern equipment is equipped with similar "brains". This leads to a reduction in electricity consumption to a minimum.

System Benefits

There are 5 main advantages in the operation of an air conditioner with ventilation:

1. Fresh air at any time of the year;
2. High-quality air purification;
3. Work in the mode of conditioning and ventilation;
4. Ease of management;
5. Quiet operation of the equipment.

Regardless of the season, you can enjoy clean air in your apartment. Not only that, you won't feel the unpleasant cold in winter that can result from using the natural inflow. Thanks to the installed heaters, the air will warm up before entering the room. Modern technologies allow such a system to work in all weather conditions.

A particularly useful quality is air purification. After all, if you live in a densely populated city, then it is not news to you how much dirt is in the street air. Thanks to filters, dust and bad smell exhaust gases you are no longer afraid. Of course, you will sometimes have to change filters, but what can be more expensive than your health.

split system

Any modern split system with ventilation is designed to supply air not only to one room. If you place a network in the apartment ventilation ducts, it will be possible to create the same conditions for living in all rooms. It is only worth noting that the equipment will not be able to create different climatic conditions for rooms.

What could be easier than setting up the operation of ventilation with air conditioning with just a couple of clicks on the remote control buttons. The air conditioner will independently adjust all the equipment thanks to the sensors. You just need to set the desired temperature and set the required amount of incoming air.

The silent operation of the air conditioner is achieved thanks to carefully selected materials that absorb all sounds. Also, during installation, materials should be used that will absorb vibration and sounds from the operation of the equipment.

What should not be forgotten

Extractor fan in the kitchen

Ventilation requires supply and exhaust. You took care of the first one, but is the hood strong enough to remove air? In order not to ask yourself this question in the future, install a hood in the kitchen and a fan in the bathroom. Thus, you can once and for all forget about problems with ventilation and enjoy only fresh air.

When choosing bathroom equipment, it is important to choose the right equipment. It must be safe and sufficiently productive.

Fan in the bathroom

It is better to install a fan in the bathroom during repairs, so that you can hide all traces of repair work under the lining.

Supply air conditioning complex

The air conditioner is not designed for air exchange, it cleans and cools the environment in a closed space. But the ventilation shafts that have fallen into disrepair apartment buildings, the installation of sealed plastic windows deprived the apartments of natural ventilation. The air in the room becomes unhealthy, there is not enough oxygen, the proportion of carbon dioxide increases. Can an apartment air conditioner be a supply air conditioner?

It is not yet possible to combine the two functions of air preparation in a full-fledged mode. Most best systems can only use the air supply from the street for 30% of the total capacity. At the same time, the air conditioner becomes much more complicated and the price rises.

For houses and apartments, only single-block air conditioners, various modifications, split systems can be used. They serve to ensure the regime on an area not exceeding 100 m 2. We will not consider cassette and column air conditioners.

Duct air conditioner with fresh air supply

The device of the channel system is two-module. One block, compressor-condenser, is outside the perimeter, evaporator is located inside the room. They are connected to each other copper pipes with freon and electrical wiring. The evaporation unit can be hidden in the lining of the room. Air conditioners with the function of fresh air inflow from the street produce air exchange into the room for 2-3 hours. Physiologically, the air becomes healthy, saturated with oxygen. These air conditioners include systems from Daikin "Ururu Sarara". Hitachi and Haier created their own models with an influx of fresh air.

The technology for cleaning and mixing air flows is complex. In a special block outside the perimeter, the air taken from the street passes through a manganese catalyst, adsorption of impurities, including odors, occurs. There is a filter at the inlet to the air conditioning system, on which small debris, insects and other external dirt remain. After the gas flows are mixed and passed through a photocatalytic filter, where they are biologically disinfected. Clean air is enriched with vitamins and hyaluronic acid. healing product supplied to the room.

Duct air conditioner with fresh air admixture

The apartments use multi-split systems. They represent an installation with one unit placed outside, there can be 2-4 indoor modules. The system is equipped with an additional device for preparing air from the street. In such air conditioners, fresh air intake does not exceed 10% of the total volume in the circulation system. A specialist can install and correctly calculate a multisystem. At all exit points, the air parameters will be the same. This is the main disadvantage of a multi-point split system. More than 4 sampling points are not provided, because it is difficult to balance such a system in terms of performance.

Using the admixture of air from the street, a split system with a wall-mounted indoor unit operates. But at the same time, the external unit of the air conditioner is modified, a fan and a mixing chamber are used. Next to the perimeter, an air preparation unit is installed, providing for winter heating and a rough cleaning grid from debris and living creatures.

Air conditioner that takes air from outside

The channel split system uses supply schemes most competently. Does this air conditioner take air from outside? One remote unit is located outside the circuit, the evaporators are connected to it by piping, mounted in a suspended ceiling or false wall. An outdoor air preparation unit is used, which is supplied to the system in several places. Condition - a place behind the wall or under the floor, sufficient to accommodate the equipment. The system is programmable, the regulation is carried out by an electronic unit. The installation for preparing the air supply from the street and the ducted air conditioner have different control panels. The admixture of fresh air can be 30%. As a result of renewal, the balance of carbon dioxide and oxygen content changes.

Fresh air conditioners for apartment

Another type of split system is the supply and exhaust air conditioner in the Hitachi product line, they are not very powerful, air exchange reaches only 8 m 3 per hour, but this amount is enough for a bedroom. An example of a supply and exhaust split system is the Hitachi RAS-10JH2 air conditioner. The model has an inverter compressor, 2 pipes are used - supply and exhaust. Air is removed forcibly, fresh air from the street can be heated. The remote control has separate options for supplying air from the street and removing exhaust. One mode is chosen, then the system is tuned to an equilibrium state.

Haier offers 2 models of premium fresh air conditioners: Aqua Super Match AS09QS2ERA and LIGHTERA HSU-09HNF03/R2(DB). In these settings supply system air is an optional extra. But having bought the equipment, it is possible to provide air renewal with a flow rate of 25 m 3 / hour. Both models of conditioners have the built-in function of an admixture of air from the street. To do this, the external unit has a pressure fan and a chamber for mixing two gas streams. flexible hose with outdoor air can be introduced directly into the room in one way or another.

Rules for placement of block air conditioners with air supply from the street

When installing evaporators on the ceiling, it is important that the flow of cool air does not reach the location of people. Therefore, narrow slotted blinds are used. The higher the ceiling, the better the oncoming gas flows are averaged. In a channel split system, the distance between the normal and suspended ceilings is at least 25 cm. The same applies to the false walls behind which the channels pass.

Anyway duct air conditioners or split systems with an influx of fresh air at a price will cost more, it is more difficult to operate than a separate supply and exhaust system and an air conditioner. Devices 2 in 1, naturally, have somewhat truncated capabilities.

Air conditioner with forced ventilation

Supply ventilation provides fresh air to the building, and at the same time cleans it from dust and heats it. characteristic feature of this whole system is the injection of air into the building, while the displaced air is removed through special ducts and outlets. The advantage of such a device is the ability to thoroughly clean the air, the humidity and temperature of which can be controlled.

Conventional ventilation systems are air ducts, which are mainly located in bathrooms and kitchens. Through them natural way polluted air leaves, and the cracks in the windows and doors act as a pump, supplying fresh air from the street. This simple scheme is called forced natural ventilation.

But such ventilation has certain disadvantages - its capacity depends on wind speed, temperature and other factors. And with the advent of plastic windows, it became ineffective.

Supply ventilation characteristic

To increase air exchange, they began to use a special supply ventilation device. These devices come in a variety of configurations. by the most simple method is to install the supply fan in a hole in the wall or window. The disadvantage of this method is the entry of very cold air in winter.

The supplied air must be at least +16 ºС. Otherwise, a temperature drop can contribute to people getting sick or damaging furniture and peeling wallpaper. Based on this, a normal system for such ventilation should include a multi-level overheating protection system and a heater. In addition, there must be an air filter so that a lot of dust does not get in with the air, and good sound insulation.

The supply ventilation system has three modes of operation:

• winter mode, air heating using a water heater;
• summer mode, cooling it with a water cooler;
• standby mode, there is a control against freezing of the water heater and air temperature when the mode is off.

Supply ventilation modes

Summer ventilation mode It can be with or without heating. Heating occurs when the fresh air temperature is 5 degrees lower than the set temperature. This device works in ventilation mode, but when the temperature drops relative to the limit, heating is turned on to the set temperature. After the required temperature has been reached, the regulation ends after 30 minutes.

Summer mode without air heating is presented as follows. The system also operates in ventilation mode. If the temperature drops below +5 ºС, then the device switches to standby mode.

By the way, if the operating mode of the system does not correspond to the season, that is, the air temperature outside, the device will emit sound signals.

Winter mode has a heating function. Supply ventilation with heating heats the outside air up to set temperature. It can be set within +15 ºС to +30 ºС. If you turn on this mode at a temperature of more than +5 ºС, then the system will beep and switch to summer mode.

In addition, there is also a mode of operation in high humidity, for example, during rain. The supply air is warmed up to the set temperature from +15 ºС to +30 ºС, and the fan speed remains minimal and does not change.

One of the popular devices is a split system with forced ventilation. This is an excellent replacement for air conditioning and ventilation, so it successfully solves the problem of ventilation.

In addition, it is better to use filters for supply ventilation with any device. They purify the air that enters the building. They also carry out medium and fine cleaning, their use guarantees a longer life of ventilation and no need to repair it.

Air conditioners appeared on the specialized appliance market relatively recently, but a short time they managed to gain great popularity. Today, this device can be found in almost every home.

Manufacturers present to the attention of buyers various models of air conditioners with forced ventilation. Devices with a wall and channel arrangement of the indoor unit are very popular.

The structure of standard and modern models of air conditioners, with additional elements, is almost identical, the difference is only in the presence of an additional special air duct.

Channel models of air conditioners are additionally equipped with a special device, the action of which is aimed at heating the air flow coming from the street in the cool season to a certain temperature.

Varieties of devices with forced ventilation

As mentioned earlier, the difference between standard designs and devices with forced ventilation is the presence additional element- a special air duct. Therefore, the difference between different models from each other lies in the principle of the device of the duct channel.

Membrane

The device of air conditioners of this type includes a special membrane, with the help of which the working processes of the channel are adjusted. characteristic feature The functioning of the membrane is in a special passage of air flows, in which oxygen penetrates into the room much better than other gases. Thanks to this feature, the unit is able to perfectly maintain the appropriate level of oxygen in the building. Similar models of air conditioners equipped with membranes are quite difficult to find on the specialized instrument market, the cost of such structures is quite high. In addition, it should be noted that the installation of such a device will cost the owner a rather large amount.

Modular system

This device basically plays the role of an additional element of the air conditioner. The design includes special components that ensure the smooth operation of the device. In addition, the design of the module includes small air duct tubes through which the main air flows pass. To put it simply, the module is an ordinary small-sized hood. The disadvantage of such a device is its size. The large-sized box is fixed on the wall, in close proximity to the external unit of the air conditioner. The second significant drawback of such models is the limited volume of air exchange, which is not enough for the full breathing of even one person. At present, there are almost no such modular systems left on the Russian specialized market of devices. This is due to poor technical and operational characteristics of modular systems. Many manufacturers of these devices are withdrawing them from production and from retail outlets.

Conversion of some air conditioning devices

the most optimal and the right option in this case is the transformation of the outdoor unit of the air conditioner. This is quite feasible, it is enough just to correctly combine the ventilation and special cooling unit of the device with the help of an air duct. Air flows in this case will flow precisely through the duct channel.

This method of converting some air conditioner devices will help to significantly increase the volume of air masses supplied to the room and provide the optimal amount clean air for breathing. The price for such models of air conditioning systems is quite high, the installation will also require a decent financial investment.

Other types of fresh air conditioners are modifications of the models described above. Thus, all models of such air conditioners have one common feature– low level of air exchange. The level of clean, oxygenated air is about 10 percent, and the air flow is about 20 cubic meters per hour, which is about 50 percent of the required rate. The highest scores among various kinds air conditioners belong to devices with a duct arrangement of the indoor unit, they provide about 25 percent of clean air enriched with oxygen. Such systems have one, but very significant drawback - complex and time-consuming installation.

From all of the above, it follows that the most correct and appropriate solution to this issue is to install an air conditioner in the dwelling, equipped with forced ventilation, sometimes it is enough to do this in one room of the apartment. A high-quality air conditioner, additionally equipped with forced ventilation, is able to provide the necessary amount of air directly from the street, while purifying it from various impurities and contaminants harmful to the human body.

Positive properties of air conditioners equipped with supply ventilation

1. Perhaps the most basic and important advantage of air conditioners and ventilation systems can be called the timely provision of premises with clean, fresh air, desired temperature cool in summer and warm in winter. This became possible due to the equipment of the devices with special modern heaters, with a digital control system, the action of which is aimed at heating the air masses before entering the room. This unique and practical development of engineers significantly increases the efficiency of the devices at low negative temperatures.
2. Air conditioners equipped with supply ventilation perfectly clean the air masses entering the building directly from the street. This is especially true for buildings located in the city center or in close proximity to a busy highway. For owners of such living space, the problem of air purification is especially acute. Modern models of air conditioners are equipped with efficient filters, reusable, which qualitatively purify the air entering the room from the street, are easy and quick to clean and serve for a long time.
3. An important quality modern air conditioners is the possibility of processing and supplying fresh air to several rooms at the same time. When selecting and installing an air conditioning system, it is necessary to seek qualified help from specialists, in this case, long-term operation of the device is guaranteed, as well as the most effective cleaning and supply required amount air into the room.
4. For many owners of air conditioners, control of the device is a rather serious problem, which cannot be said about similar models. They are equipped with modern devices and special software which greatly simplifies the management of the air conditioning system. It is only necessary to set the optimal temperature level on the control panel of the device, the rest will be done by the system itself and the air conditioner.
5. Modern models of air conditioners operate almost silently. This is due to the use of special materials that provide reliable insulation. various sounds and vibration.

The choice of a suitable air conditioner model depends on the wishes and financial capabilities of the client, while it is important to take into account the technical and performance characteristics device.

Modern climatic conditions force mankind to look for new sources of air purification. Apartment buildings are practically airtight and do not have effective ventilation. In this regard, the concentration of oxygen in the room decreases and, accordingly, the mental and physical activity of the inhabitants decreases.

The only solution for today is the creation of forced ventilation. The premises are equipped with special devices with supply air valves. Such air conditioners with air flow from the street usually deliver no more than 40% of the air into the room.

Need for fresh air

It's no secret that fresh air is vital to maintaining health. Therefore, manufacturers in the area climate technology increased attention to ventilation issues. Every living being needs oxygen, but because of the pace modern life people forget to take care of themselves, which leads to poor health and illness. Purchasing an air conditioner with a fresh air intake mode will make it possible to work effectively throughout the day in a closed room.

Why you need constant micro-ventilation:

• Constant air changes increase the level of oxygen in the room.
• Oxygen has a positive effect on metabolism and the functioning of the respiratory and immune systems.
• There is a stabilization of pressure and the work of the heart improves.
• Thanks to oxygen, stress levels are reduced and the brain works more efficiently.

Consequences of lack of oxygen:

• General well-being worsens, malaise appears.
• The pressure rises and the headache increases.
• There is irritability and constant fatigue.

A modern air conditioner performs not only a function. It simultaneously serves as a cleaning system, a heating device, and can supply air to the room.

The main task of a split system is to provide comfortable conditions life.

Types of split systems with admixture

The air conditioner with air flow from the street differs from the classic split system by the presence of a separate air duct. Models of this type differ from each other in the structure of this channel.

Consider the types of air conditioners:

1. With membrane. Such an air conditioner is equipped with a membrane, it is she who is responsible for the operation of the channel. Feature: uneven throughput. The membrane is designed so that oxygen passes through it better than other gases. Such devices are quite expensive and rarely found on the market.
2. Modular system. This is an addition to existing system in the form of a heat exchanger with an air duct. It is equipped with an outdoor unit and is installed outside the room next to the air conditioner. The module has two tubes through which air exchange and thermoregulation take place. Minus: overall outdoor unit and low air exchange. Modern market almost does not sell such designs, since they are significantly inferior to their counterparts.
3. Modified outdoor unit. This solution is the most logical and is a combination of cooling and ventilation units. Between the outer and inner parts of the air conditioner, an air duct channel is installed for supplying oxygen. Minus: high cost and average air exchange (the amount of ventilated oxygen is calculated for the presence of only one person in the room).

The price of air conditioners with air flow from the street starts from 30 thousand rubles. and depends on the required functionality.

Also on sale you can find modifications of these types of systems. But all of them have a drawback - a low rate of air exchange. Channel systems give a better result, but their installation is difficult for an ordinary apartment.

Duct split systems

Hitachi outdoor air conditioner

The most popular among the products of this manufacturer is the Air Exchanger series. These air conditioners are also distinguished by the presence of a modern Nano Titanium filter, which is able to capture, in addition to dust, formaldehyde and bacteria, as well as purify the air from odors.

When the night mode is on, the air conditioner independently regulates the temperature and humidity in the room. The system has a built-in pollution analyzer that provides information about the freshness and purity of the air.

Principle of operation: when laying a freon route, a hose is additionally installed to supply air masses. External and indoor blocks equipped with fans for oxygen supply. Because of this design, extra noise in room.
