Abstract :
The CO2 heat pump system used in automotive air conditioning is analyzed theoretically in this article. The result shows that the temperature of the low-temperature side has a greater influence on the heating performance of the system than the temperature of high-temperature side. The air source heat pump system and the coolant source heat pump system are introduced and compared. By placing a heater core to recover exhaust heat from the engine, the performance and the heating capacity of the system are improved dramatically. Furthermore, through the theoretical analysis, the result that the coolant source heat pump system where the coolant flowed through the heater core first and then the evaporator had a better performance than other systems can be proved.
