Can I include air conditioning or winter heating operation rules

Can I include air conditioning in the winter

By purchasing a home split system, you suddenly think aboutwhether it is possible to include air conditioning in the winter? The question is quite reasonable, because even in the instructions and technical documentation for purchased equipment climatic states that operating temperature range of reversible air-conditioning (as they are often bought and sold) is from -5 to +25 degrees. It turns out that if -5 outside, the split-system can easily cope with the space heating function. And what if there is not -5 and -30? Let's find out how real the air conditioner winter.

What conditioners are suitable for heating?

Pay attention to the instructions in yourair conditioning. For sure you will see there is already articulated above parameters, well, or very close to them. If the temperature of the board is less than -5, the air conditioner simply lose as stated in the technical documentation of heat output. Sooner or later, she did drop to zero. But all the same, whether it is possible to use the air conditioner in the winter?

Domestic air conditioners generally not beoperate in winter. The fact that dissolved in the refrigerant oil is effectively "operates" only when the parameters specified in the instructions. Breaking it (instructions), you run the risk of "losing" his friend forever, because the friction parts will be almost dry running because of thickened oil, and this will inevitably lead to rapid wear of the compressor and its ultimate failure. That's why you can not include air conditioning in the winter!

"Winter" temperature for efficient operation of reversible air conditioners should not be lower than -5 degrees

But then there is another question: "Why do some companies impose purchase of a special" winter kit ", which allegedly enables the air conditioner to work in sub-zero temperatures with no loss of thermal performance?" The answer is banal: "In order to cash in on those who will believe this bike." In fact, the low-temperature kit consists of three units: crankcase heater, preventing oil thickening, drainage, heating, prevents the formation of ice crust on the outdoor unit and the external moderator fan speed. These measures are aimed at expanding the range of split system operating temperature, so you had the opportunity to use your winter conditioning to cool the room, not for its heating.

Due device start winter winter air conditioning operation is possible, and not in the range specified in the instruction, and at much lower temperatures.

It turns out that the work of the air conditioner for heating in winter- A myth? Not really! Some models are split systems, such as MitsubishiElectric and Daikin, can be used for heating rooms, even under the condition that the temperature outside is -25 degrees, that you will agree, a good achievement.

Conditioners brands Mitsubishi Electric and Daikin can operate even at a temperature of -25 degrees

Possible problems with the misuse

It is worth knowing that the air conditioning in the winter can cause several troubles, and their character depends on which mode you are being exploited and which at the same time the temperature was in the street.

Mode "Heating", the temperature is below -5 degrees

  • external power emitted from the condensate during air conditioner begins to be covered with ice;
  • deteriorating heat, reduced heat output;
  • liquid refrigerant can enter the compressor, causing it to break.

"Cooling" mode, the temperature is below 5 degrees, and

  • freeze the outdoor unit and drain pipe;
  • reduced compressor performance;
  • It increases the risk of damage to the compressor when the air conditioner is turned on.

Preparation of domestic air-conditioner for the winter

If air conditioning is not included in the winter, or rather, its operation is not planned, it is worth it to prepare for the cold. To do this:

  1. include split-system "ventilation" mode for 2-2.5 hours to remove the moisture from the indoor heat exchanger;
  2. clean filters (can be on their own);
  3. close the outdoor unit waterproof material.

Check the air conditioner in the winter

Another relevant for many issues remain"A snack", "How to check the air conditioning in the winter?" Check it could be only if the outdoor temperature rises to the minimum specified in the instructions or if you have a "winter kit." No other way!

So if you bought and decided to installsplit-system in winter, when outside -25-30 degrees, you should either wait for warming and then deal with the installation, or to trust the company that sold you the HVAC equipment, and turn on the system in the spring. Yes! And do not forget! Before you check the air conditioner in the winter, make sure that the street really is the temperature that corresponds to the parameters in the statement.
