Why does the air conditioner frost

Why does the air conditioner frost Q: Why does frost occur when the air conditioner is running? Answer: When the air conditioner is performing heat pump heating operation, the surface temperature of the heat exchanger of the outdoor unit will be very low. When it is lower than 0 ℃, the moisture in the air will form frost on its surface, and the relative humidity of the air The higher, the lower the surface temperature of the outdoor unit heat exchanger, the more serious the frost. The frost phenomenon will not hinder the circulation of air and will not affect the heat exchange efficiency of the heat exchanger. Mitsubishi Electric adopts intelligent defrosting mode, the temperature is more stable.
