Abstract

The embodiment of the invention relates to the technical field of air conditioners and discloses an electric automobile heat pump air conditioning system. The system comprises a first vehicle external heat exchanger, a first air supply compressor, a first four-way valve, a first vehicle interior heat exchanger, an air supply evaporator and a temperature control module, wherein the air supply evaporator is communicated with the first external heat exchanger, the first external heat exchanger is communicated with the first air supply compressor through the first four-way valve, and the first air supply compressor is communicated with the air supply evaporator; the air supply evaporator, the first interior heat exchanger, the first four-way valve and the first air supply compressor are sequentially communicated, and the temperature control module and the air supply evaporator form a cooling loop. According to the heat pump air conditioning system of the electric automobile, switching between the refrigerating mode and the heating mode can be achieved; waste heat generated by parts such as a battery and a motor can be effectively recycled, and refrigeration energy efficiency of the system and the heating performance at the low environment temperature are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an electric vehicle heat pump air conditioning system. Background technique [0002] Electric vehicles refer to vehicles that use electric energy as a power source and are driven by electric motors. They belong to new energy vehicles, including pure electric vehicles, hybrid electric vehicles and fuel cell electric vehicles. Because electric vehicles have less impact on the environment than traditional vehicles, their development prospects are widely optimistic. [0003] During the operation of electric vehicles, batteries and motors will generate a lot of heat, especially in summer when the ambient temperature is high. If the heat is not dissipated in time, it will not only affect the working efficiency of batteries and motors, but also shorten their use. life. In the prior art, this part of heat is often wasted. If it can be effectively recycled, the overall energy e...
