Will it be warm to turn on the air conditioner when it is very cold?

Principle of air conditioning heating Air conditioning heating is realized by the reverse flow of Freon, and it is the phase change of Freon liquid and gas that absorbs heat from the environment and then releases heat to realize heating. Therefore, the lower the heat in the outdoor environment, the lower the heating capacity of the air conditioner. Therefore, the colder the weather, the less it seems that the air conditioner will "generate heat".

Measuring the heating performance of an air conditioner mainly depends on its heating capacity. According to the national standard, the calculation of heating capacity is based on the heating effect of this type of air conditioner at 7℃ (dry bulb temperature). If the temperature drops below zero, the heating effect of the air conditioner will be greatly reduced, and some brands of air conditioners can't even be turned on to zero. Therefore, in the sales of air conditioners, it can be found that many brands promote "normal start at minus 15℃" as an important selling point, which is actually a bit of commercial speculation flavor, because the national standard only measures the minimum starting temperatures of minus 7℃ and minus 15℃, and the engine will bear a great load, causing great damage to the machine. In the domestic sales of heating and cooling air conditioners, the cooling effect is basically up to standard, but the heating is greatly affected by the temperature, so the rated machine power can not adapt to the low temperature environment and can not "generate" more heat. The birth of inverter air conditioner solved this embarrassment to a great extent. Inverter air conditioner is the new favorite of the market. Using frequency conversion technology, it can quickly reach the set temperature after starting and then enter low frequency operation, which is more energy-saving. But also can adapt to large temperature difference, accelerate the low-temperature operation of the compressor, and promote the increase of freon flow to generate more heat. The advantage of inverter air conditioner, in a popular phrase, is that "it is overqualified for refrigeration alone, and it is really valuable for heating." When the temperature exceeds 35℃, there is little difference between variable frequency refrigeration and non-variable frequency refrigeration. When the temperature is below zero in winter, the effect of variable frequency heating is obviously better than that of non-variable frequency heating.
