- Electric vehicles are equipped with heat pump system as an alternative to existing engine heat source for heating.
- The heat exchanger, which absorbs the high heat source of the refrigerant in the heat pump system and applies it to heating, The chiller is a type in which a pin is applied inside the heat exchanger (for low pressure) and a chevron shape of the plate itself (For high pressure). The chiller is operated by the pressure of the refrigerant in the system. It is divided into two types for high pressure and low pressure.
