How to turn on the warm air on the air conditioner? Heating activation guide

Features of operation in the winter

To maintain comfortable conditions in the cold season and at the same time not disable the device, you must carefully study the instructions. It indicates the temperature range in which the unit is able to operate with maximum efficiency. Most often it is from -5 to 25 degrees.

However, in summer, the unit also operates at higher ambient temperatures. At the same time, its performance drops, but it does not fail.But in winter, a violation of the operating conditions of the air conditioner can lead to unpleasant consequences. In such a situation, you should understand how to turn on the air conditioner for heat, while maintaining the unit's performance.

To do this, you have to understand what is happening. In most budget models, the compressor and condenser are located in the outdoor unit. If the outdoor temperature drops below the minimum allowable, the oil in the compressor becomes thicker. As a result, it ceases to lubricate the moving parts of the device with high quality, which leads to premature failure of the unit.

When it is necessary for the air conditioner to blow warm air, the refrigerant must take heat energy from the environment and deliver it to the room. At low temperatures, freon is not able to heat up to the desired state, and then the efficiency of the unit is reduced. It should also be remembered that in severe frost, the phase transitions of the refrigerant fail.

Why is the air conditioner not heating?

Air conditioner does not defrost

But what if the heating function in the air conditioner is not available for any reason?

Consider several factors that can affect its operation:

1. Very coldy. An electrical appliance may simply not be designed for space heating under such weather conditions. This is a common reason why the air conditioner does not heat properly. The power of some devices is not designed for such a strong temperature difference, so the device is not able to heat the air in the room by more than 3 degrees. But provided that it is from 0 to +5 ° C outside, the device heats the air with the highest productivity.

1. Heat is not supplied when there is airflow from the indoor unit.The inflow of air into the room has a temperature similar to the street. There is clearly a problem with the compressor. There may be a breakdown in the four-way valve, which is the responsible element for changing the operating mode of the air conditioner. If there is damage, it cannot ensure the switching of the operating modes of the device from summer to winter. In this case, the compressor will need to be replaced or repaired.

1. The "defrost" mode is violated or absent. Under such circumstances, the appliance still operates in normal air cooling mode. Air supply units are in operation. It doesn't work in heating mode.

Other reasons and ways to fix

Some models of air conditioners are equipped with a heat generating coil, which is installed on the indoor unit of the device. A fan blows warm air around the room. When the heating of the atmosphere is poor, it is worth checking the device for problems with the supply of the spiral or with the fan of the indoor unit.

Some problems of this nature can be eliminated by the consumer on their own. The problem may be hiding in the simple freezing of condensate in the internal tubes of the electrical appliance, which leads to their clogging and obstruction.

If it’s already cold outside, then temporarily turning off the device will not help. The frost inside the tube will not melt due to negative temperatures outside. It remains to wait for warming, or you can try to start the heating wire that runs along these tubes. This will help if there are no problems with the external unit.

Possible causes of condensation:

1. Unprofessional installation work that violated the integrity and operation of the air conditioner.
2. The presence of a manufacturing defect in the device.
3. The presence of microcracks through which the liquid enters the device. Here, the possibility of damage to components mechanically or due to improper operating conditions is not ruled out.

Under such circumstances, it is not possible to warm up the circuit. But if you try to switch the modes from heating to cooling, and after a while in the reverse order, the problem may be fixed. It may take several such alternate switching so that the cork melts and slides out of the tube, freeing the passage.

Switching the air conditioner from cooling to heating

Due to the formation of cracks, other damage with the appearance of microscopic gaps, a pressure drop in the freon circuit may occur. This is possible due to the loss of a small amount of refrigerant. Under such circumstances, the air conditioner will not cool and heat well.

The problem with refueling with freon will be eliminated by the service departments involved in maintenance. Actions are performed through the fittings pipe, located in the external block outside the building. Specialists use the collector for nitriding, evacuation and refueling.

But you can determine such a need yourself. To do this, you need to find and examine the scale of the unit, which indicates the actual indicators of the presence of freon. Comparing them with those recommended according to the device passport, they identify the need for refueling.

Masters use special thermometers to measure freon vapor at the entrance to the compressor. And the collector readings will indicate digital data on the state of pressure. The presence of a temperature difference of more than 8°C between these two figures indicates a need for refilling.

Remote control

Each of us knows that a remote control is attached to this device. Setting up the air conditioner with the remote control is quite simple. The instructions describe in detail all the actions that can be performed with the air conditioner by controlling the remote control. You can easily set it up so as not to catch a cold. Using the remote control, you can set exactly the temperature that you want. You can easily make the air warmer or colder. Most importantly, you can do it from the comfort of your couch or office desk.

But what to do if suddenly the remote control was not at hand? Here is a list of the necessary actions when you need to turn on the air conditioner for heat without a remote control:

1. First you need to make sure that the air conditioner is working. Check the wiring to it. If it is in place and the wires are not broken or bitten, then the following instructions can be followed.
2. On the front of this household item, find the plastic cover. It is small and rectangular in shape. It is located mainly a little lower than the so-called air conditioner curtains. This cover must be carefully lifted (grabbing it with your fingers from two opposite sides), slightly pressing on the cover itself.
3. Under this cover is a panel on which there should be a button. Where exactly it is located (left or right) depends on the model of the unit. But often it shines. If the device is in working order, this button will glow greenish (rarely orange) light. Of course, under it is the corresponding inscription in English "on and off".
4. This button should be pressed and held for a while (several seconds). The device should either work or turn off. This is to turn the unit on or off. If you need to change warm air to cold, then you need to press the button without holding it.

It should be noted that you will not be able to change the temperature using such a panel, for this you need a remote control. Therefore, do not delay the search for it. If the remote is broken, you just need to purchase a new one. To do this, it is enough to know the make and model of the device.

Nuances of operation

Modern models of air conditioners are quite complex household appliances, the setting of which requires compliance with basic rules.

1. It is necessary to clearly select the power of the product depending on the volume of the room: in regions with a very hot climate, it is necessary to install systems with more power, with improved characteristics of the cooling mode.
2. Always correlate the operating mode of the product with the weather conditions outside.
3. In order to prevent the occurrence of any colds, it is necessary to fine-tune the equipment in the cold mode.
4. Carry out regular maintenance - these activities will allow you to ensure the normal operation of the product, and the whole family a safe and comfortable microclimate.
5. Installation, maintenance and repair of equipment should only be done by professionals.

Climate systems can be installed in any premises, regardless of their configuration and dimensions, because modern technology copes with the task without any problems. The user must only follow all the rules and recommendations voiced in this article.

Devices with winter mode

It should be understood that installing additional winter parts is not always possible successfully. Further operation of the device depends on the parts themselves, the dimensions of the air conditioner and the installation method, so it is better to immediately purchase an air conditioner that will work in winter for heating and in summer for cooling. There are 2 types of air conditioners that work well in winter.

1. Cooper&Hunter CH-S09FTXLA Arctic Inverter is a suitable option for heating a 25 sq. m. The average engine power is 2.8 kW. Tolerates outdoor temperatures down to -25°C. The device includes a smart part that checks all parameters before starting the engine. The minimum cost of this air conditioner model is 33,800 rubles.
2. GREE GWH12KF-K3DNA5G - this model works well at optimum temperatures down to -18°C. A room with dimensions of 35 sq. m. can be fully heated. The device consists of an electrostatic filter and a smooth start. Anti-freeze protection of the outdoor unit is provided, which consists of particles of crankcase heating and a drain. The starting price of such a device is 32,000 rubles.

The GREE GWH12KF—K3DNA5G air conditioner operates at temperatures up to -18 C

Buttons on the remote control of the air conditioner

Any split system remote control has five main buttons:

1. Power button;
2. Mode switch button;
3. Double temperature adjustment button;
4. Shaft speed adjustment button;
5. Blind direction adjustment button.

More information about the meaning of these buttons can be found in the article cooling settings.

But before picking up the remote control, first turn on the air conditioner (like any electrical appliance). Most often, this is just a plug that needs to be plugged into an outlet.The air conditioner can also be powered through the machine in the electrical panel. In general, depending on the method of connecting the air conditioner, we turn on the machine or plug the plug into the outlet. At the same time, you should hear a beep from the indoor unit. If the unit does not react in any way, then read the article, because of which the air conditioner may not turn on. After a successful power supply, we pick up the remote control and proceed further!

Installation of the air conditioning system

Air conditioners should be operated with strict observance of the most necessary standards - this action will ensure the extension of the service life to the maximum, and also saves the owners of climate equipment from the need for expensive and frequent repairs, which, as a rule, is carried out with the replacement of expensive parts like a compressor or control board.

Before installing the air conditioner, it is required to study in detail the instructions, which indicate how best to perform these actions, as well as how to turn on the air conditioner for heat. Experts advise not to save on such responsible actions as installation, but to trust professionals. But with elementary functions you need to figure it out yourself.

The installation of the system must be carried out in accordance with the generally accepted rules for using this device - it is necessary to provide the system with an easy air inflow and outflow.

Switching the air conditioner to heat is carried out using the air conditioner control panel (remote control or wall-mounted).The operating mode of the air conditioner for heat is usually indicated on the control panel with an icon with the image of the Sun. In addition, in order to operate air conditioners before using it, it is necessary to conclude a special contract with the company that is its supplier regarding the service of this system.

Before you start using the air conditioner, you need to find out all the details and features of its operation - how to turn on the air conditioner for heat or cold, how often should you ventilate it, and is it possible to carry out maintenance work yourself? Everyone should know that regular maintenance of this unit will prevent premature failure of the system. This, for example, often happens in the summer - at a time when service companies are fully loaded with orders and simply do not have any opportunity to quickly respond to a call and restore the functionality of your particular system. So, if the climate equipment suddenly failed during a difficult period for repair, and you do not want to ruin it completely, you should not start repairing it yourself. You should disconnect the air conditioner from the mains and wait for a specialist who can carry out a real qualified repair, taking into account his knowledge in this area.

Winter work

The heating mode in air conditioners appeared quite recently, therefore, they are gaining fame only now. The climate of the country does not always please with warmth, and in the intervals between the heating season and summer it is sometimes quite cold indoors.

The instructions for each air conditioner indicate the maximum temperature at which the device can be used. Many devices have a lower limit of 0 C, and some reach up to -25 C.It is impossible to turn on the temperature below the specified indicator on your own.

There is oil inside the circuit, which, during the operation of the device, lubricates the parts of the compressor and the outdoor unit. It must always be in abundance so that the device can work well. When the temperature outside gradually drops, the oil begins to thicken. Because of this, the compressor turns on with all its might, so it wears out, and then completely breaks down.

When it is very cold outside, the liquid that should flow into the drain freezes. Because of this, after a while, the condensate in the indoor unit also freezes.

Therefore, if the instructions indicate at what temperature the device can be turned on, and at what temperature it is forbidden, then it is better not to risk it. If the air conditioner has 1 operating mode (for cooling), then it cannot be used in winter. Such a device is allowed to heat the room in autumn and spring, until the temperature outside drops to 0 ° C.

If the air conditioner has 2 modes (for cooling and heating), then it can be used in winter, but always at the temperature indicated in the instructions. You can also convert the split system from mode 1 to mode 2 using special parts that are sold separately in the kit.

Some models of air conditioners - inverter air conditioners - can heat the room even in winter, at fairly low sub-zero temperatures.

When the heating mode is turned on at the beginning for 3

The fan may operate for 5 minutes to prevent cold air from blowing in while the air conditioner is warming up.Since the air conditioner heats the room by extracting thermal energy from the outdoor air, its heating capacity may decrease if the outdoor temperature is extremely low. Use an additional heater in combination with the air conditioner if you feel that the air conditioner is not heating enough.

In Heat mode, the air conditioner will heat the room. You can set the temperature and fan speed to feel the operation of the heating device in the cold season.

At what temperature to turn on the air conditioner for heating?

The allowable lower ambient temperature barrier for air conditioners operating on R-22 refrigerant is -5 ºС, on R-410A up to -10 ºС for non-inverter models, and up to -15 ºС for inverter models. At lower temperatures, the compressor oil freezes, ceases to dissolve in the refrigerant, which leads to a “dry start” of the air conditioner, which can further lead to compressor failure. To operate air conditioners for heating at lower temperatures, it is necessary to install a “winter set”. We recommend enabling heating air conditioner at ambient temperature up to 0ºС

When starting the split system for heating, pay attention that the outdoor unit is not icy, because. in this case, there is a risk of damage to the fan of the outdoor unit

When the split system is operating for heating below the minimum allowable ambient temperature, be sure to service the air conditioner before starting the air conditioner for cold, as Freon may need to be recharged.

Operation of the air conditioner for heating in winter

Most split systems operate for heating at a temperature of -5 ... 25 ° C.If the indicators are lower or higher, performance is lost. In winter, air conditioners should not work. This is due to the fact that the oil dissolved in the refrigerant performs its function of lubricating the compressor parts only in this temperature range. Therefore, it is forbidden to use the equipment at lower temperatures.

Despite this, some companies claim that air conditioners can heat the room even during severe frosts, and for this it is necessary to install a winter starter. Such statements are not true.

The low temperature kit consists of three devices. The compressor crankcase heater warms up the settling oil and prevents it from thickening. An electric cable heater is installed inside the outside of the drain pipe, preventing ice blockage. The outdoor unit fan speed retarder is a controller that prevents the condenser from overcooling and freezing. These devices help to extend the operating temperature range only for using the air conditioner in cooling mode.

Attention! Operation of the device at lower temperatures, as indicated by the manufacturer's instruction manual, leads to premature failure of the device. Only some air conditioners are able to heat the room at an outside temperature of -15 ° C

These include inverter devices Daikin, Mitsubishi Electric.

Inverter air conditioners are power-controlled systems.This means that when the air temperature set by the user is reached, the mechanism does not turn off and continues to work. But he does it at reduced power and constantly maintains the set parameters. The inverter extends the service life by at least 30%. This is due to the fact that starting loads are reduced. In addition, it is possible to achieve energy savings.

Advantages of air conditioning heating:

Energy saving

Heating with an electric heater

A classic electric heater in order to heat a room of 15 sq.m consumes approximately 1.5 kW to 2 kW. The heating will not be uniform and the air temperature next to the heater will be much higher than in the rest of the room, and therefore the heater will be set to a higher temperature than required. The time during which the electric heater is able to bring the room temperature to a comfortable level for a person can exceed 1 hour.

Air conditioning heating

Electricity consumption of the air conditioner in heating mode for a room of 15 sq.m. not higher than 0.7 kW. Ch., that is, more than 2 times lower. Such low energy consumption seems impossible if you do not know the principle of operation of the air conditioner for heating. The air conditioner itself does not produce heat, it only delivers it to the room by heat exchange. The same principle as for cooling, only in reverse. Heat is taken into the premises from the street, and the cold is brought out. Electricity is consumed only for the operation of the compressor and fans.

Heating of the apartment in the off-season.

In the off-season, when the central heating is still turned on, and the temperature outside is already below 10 degrees, you have to turn on the heaters.Although this time does not exceed one month in autumn and is possible with early frosts in spring, but in combination with summer cooling, this is an additional important argument in favor of the need to install an air conditioner in your apartment. In addition to high energy efficiency, such a functional ability of the air conditioner as automatic operation of maintaining the set temperature in Auto mode is very pleasant. You just need to turn on the air conditioner for heat or cold, set the temperature that is comfortable for you and maintaining the temperature will no longer require your participation.

Difficulties heating in the country

A country house is a place where living is seasonal and expensive capital heating is rarely required. In addition, the lack of gasification in garden associations makes heating not a cheap pleasure. The high price of heating is subject to a limit in electricity consumption due to lack of capacity, which makes heating with electric heaters impossible. Voltage drops are also superimposed on loaded networks.

Country heating with air conditioning

In country houses, where most often the walls consist of lightweight structures insulated inside and finished with decorative trim inside and out. Such walls work well to contain the temperature, but they do not accumulate temperature in any way. For this reason, a constant source of heat is required. This makes off-season heating of the entire house at the same time costly, and unnecessary due to non-permanent residence. Installing air conditioners in different rooms makes it possible to set different temperatures, which provides an additional opportunity to save energy.Along with the low cost of heating with air conditioning, the speed of bringing the temperature to a comfortable level is also important. Due to the ability to run a large volume of air through the heat exchanger, the air in the room heats up quickly

Some air conditioners have a surge protection function, which is also important in holiday villages with unstable power supply.

Cons of heating a room with air conditioning

A significant disadvantage of heating a room with an air conditioner is that prolonged operation of the air conditioner in this mode at outdoor temperatures below 0 degrees is not desirable. Even if you read in the instructions that the air conditioner works, for example, up to - 10, then this is not entirely true. Operation at negative temperatures involves heating the condensate drain. This is due for the most part to the fact that condensate forms in the outdoor unit during the “heating” mode and freezes when draining in the drainage outlet, forming a plug. After that, ice freezes inside the outdoor unit. Freezing ice can damage the fan. In addition, at low temperatures, the energy efficiency of the air conditioner drops. If your air conditioner is not specifically designed by the manufacturer for low temperatures, then prolonged operation in heating mode, at outdoor temperatures below -7ºC, will inevitably lead to its breakdown.

Heat pump - air conditioning for heating

Heat pumps are essentially the same split systems, but specially adapted to operate at very low temperatures. There are heat pumps on the market for operation at -25°C, -30°C, and even down to -40°C. More about heat pumps.
