2. Click on the heating. The heating mode is contrary to the principle of air conditioning refrigeration. The refrigerant filled in the air conditioning system has the characteristics of condensation, liquefaction, exothermic evaporation and gasification and heat absorption. When the air conditioner is heating, the compressor will pressurize the gas condensate to make it become high temperature and high pressure gas, and then it will condense and liquefy through the heat exchanger of the indoor unit, releasing a lot of heat and raising the indoor air temperature. However, if the outdoor temperature is lower than 7℃, the heat exchange efficiency will begin to decline, and the heating function of fixed-frequency air conditioners will basically lose when they reach -5℃, and some inverter air conditioners can work normally at-15℃.
This answer is applicable to Skyworth KFR-35GW/V3HA1B-N1,? Skyworth KFR-35GW/F2BB 1A-3 brand air conditioner model.
