The invention discloses an electric automobile air conditioner heat pump system. The system is characterized in that the system has two working modes of a heating mode and a refrigerating mode, and the system comprises a heating loop, a refrigerating loop and a four-way reversing valve. The four-way reversing valve is used for controlling the working mode of the air conditioner heat pump system and switching the current working loop into any one of the refrigerating loop and the heating loop. The invention further provides a method for conducting temperature control through the electric automobile air conditioner heat pump system. Compared with the prior art, the electric automobile air conditioner heat pump system has the advantages that when the same heating capacity is achieved, energy consumed by the heat pump system is only about half of that consumed by a PTC electric heater; and meanwhile, compared with an existing heat pump system, the four-way reversing valve is used for reversing and controlling system loop switching, the design of system pipeline loops is simplified, the number of used stop valves is reduced, and the production and manufacturing cost of whole parts of the system is reduced.
本发明公开了一种电动汽车空调热泵系统,其特征在于,具备制热模式和制冷模式两种工作模式,系统包含制热回路,制冷回路和四通换向阀。四通换向阀用于控制空调热泵系统的工作模式,切换当前工作回路为制冷回路或者制热回路中的任意一个。本发明还包含利用电动汽车空调热泵系统进行温度控制的方法。本发明涉及的电动汽车空调热泵系统,与现有技术相比具有的优势效果是:在达到同样的制热量时,热泵系统消耗的能源仅为PTC电加热器的一半左右;同时与现有热泵系统相比,使用四通换向阀换向控制系统回路切换,使系统管路回路实现了简化设计,减少了截止阀的使用数量,降低了系统整体零部件的生产制造成本。
