3.4 Function Control panel Liquid refrigerant is evaporated (evaporator), the ener- gy for this process is environmental heat and comes from the outside air. The gaseous refrigerant is com- pressed (compressor), this causes the pressure to rise and therefore the temperature too. The gaseous refrig- erant with high temperature is liquefied (condenser). -
