The invention provides an integrated R290 vehicle heat pump air conditioning system and a control method thereof, and relates to the technical field of air conditioners and heat management systems. According to the system, a refrigerant circulation system communicates with a first refrigerating fluid circulation heat system, a second refrigerating fluid circulation heat system and a third refrigerating fluid circulation heat system, and the refrigerating capacity and the heating capacity of a refrigerant can be transmitted among the first refrigerating fluid circulation heat system, the second refrigerating fluid circulation heat system and the third refrigerating fluid circulation heat system; therefore, electric control of a motor and related elements in the refrigerating fluid circulation third heat system are cooled, a battery pack is cooled or heated, and the requirements of various modes of an air conditioner in a cab can be met. The problems that the risk of flammability exists in the using process of an R290 refrigerant, and an existing air conditioner management system is numerous in parts, complex in pipeline and irregular in heat management control function are solved.
本发明提供了一种集成式R290车用热泵空调系统及其控制方法,涉及空调及热管理系统技术领域。系统包括:冷媒循环系统分别连通于冷冻液循环第一热系统、冷冻液循环第二热系统和冷冻液循环第三热系统,冷媒的制冷量和发热量,可在冷冻液循环第一热系统、冷冻液循环第二热系统和冷冻液循环第三热系统间传递,以实现对冷冻液循环第三热系统中电机电控及相关元件进行冷却、并对电池包进行冷却或加热,还可满足驾驶室空调各个模式的需求。本发明解决了R290冷媒使用中存在的易燃风险,并且现有的空调管理系统中的零部件繁多、管路复杂以及热管理控制功能不齐的问题。
