Difference between Heat Pumps and the Air

1) Function: The main function of the air conditioners is to cool the room and maintain comfort conditions when the atmospheric temperature is high The main function of the heat pumps is to heat the room when the atmospheric temperature is very low 2) Evaporator: In air conditioners the evaporator is also called as the cooling coil because it is the evaporator that produces the
