The invention provides a vehicle air conditioner and a control method thereof.The vehicle air conditioner comprises a compressor, an exterior heat exchanger, an interior heat exchanger, a first throttling device, a water receiving part and a heat exchange terminal, and the compressor, the exterior heat exchanger, the first throttling device and the interior heat exchanger can be connected to form a main refrigerant circulation loop; the vehicle air conditioner further comprises a first pipeline, one end of the first pipeline is communicated with the interior of the water receiving part, the other end of the first pipeline is communicated with the heat exchange terminal so as to refrigerate or heat a user, the water receiving part is a closed container which is closed relative to the exterior of the vehicle, and water in the water receiving part is not communicated with the environment outside the vehicle. Heat exchange between outside air and condensate water is effectively isolated, heat exchange influence on inlet air or outlet air of the heat exchanger in the vehicle is avoided, invalid heat exchange with the environment outside the vehicle is reduced, load in the vehicle is not increased, and performance and energy efficiency are effectively improved.
本发明提供一种车辆空调及其控制方法,车辆空调包括:压缩机、车外换热器、车内换热器、第一节流装置、接水部和换热终端,压缩机、车外换热器、第一节流装置和车内换热器能够连接形成主制冷剂循环回路,接水部能够承接车内换热器产生的冷凝水,车辆空调还包括第一管路,第一管路的一端与接水部的内部连通、另一端连通换热终端以能对用户制冷或制热,接水部为与车外相对封闭的封闭容器,接水部内部的水不与车外环境连通。通过本发明有效隔绝外部空气与冷凝水之间的换热,不会对车内换热器的进风空气或出风空气产生换热影响,减少与车外环境无效换热,不会增加车内负荷,有效提高性能及能效。
