Why heat pump air conditioners can be used above -5 ℃?

In order to overcome the problems in the title heat pump air conditioner without automatic defrost caused by the lack of heat pump air conditioners fitted with automatic defrosting device. When the amount of frost accumulated on the outdoor heat exchanger reaches a certain amount, the air conditioner automatically executes a defrost command and a temperature signal is sent from the temperature-sensing bag of the de-icing (frost) device to divert the four-way reversing valve from the heating condition Frost conditions, this condition and the same cooling conditions, but the air volume is small, do not let the cold wind affect the room temperature, the role of the outdoor heat exchanger at this time, the refrigerant from the compressor hot steam to frost melt. After defrosting, will automatically transfer to the heating operation, so go round again, heat pump air conditioners can be -5 ℃ above the normal operation of the environment. Automatic defrost heat pump air conditioner minimum ambient temperature is -5 ℃ design, so it can operate in -5 ℃ above environment. However, if the temperature is lower than -5 ℃, due to the heat from the outside world difficult, the heating effect will decline or poor.
