Application Of Heat Pumps in The Automotive Industry

Electric vehicle heat pump air conditioning refers to the air conditioning system applied to electric vehicle models. The heat pump air conditioning system uses an electric air conditioning compressor, which utilizes the reversible refrigeration cycle and integrates refrigeration and heating. It has the advantages of good universality, compact structure, high efficiency, energy conservation, and environmental protection, and has become a new trend in automotive air conditioning. Under winter heating conditions, the COP can reach 2-4 times, which is much more efficient than the commonly used PTC heating today and can effectively extend the range by more than 20%. Moreover, there are various solutions to the problem of low-temperature frost formation that limits its use, making it one of the few effective technologies currently applicable to electric vehicle heating.
The core components of heat pump air conditioning include four-way directional valves, electric compressors, electronic expansion valves, heat exchangers, etc. Domestic manufacturers have completed full coverage of components, mainly including Sanhua Intelligent Control, Yinlun Co., Ltd., and Aotejia.
