The invention provides a novel cooling and heating integrated heat pump air conditioning system. The novel cooling and heating integrated heat pump air conditioning system comprises a compressor, a four-way reversing valve, an indoor heat exchanger, an outdoor heat exchanger and a gas-liquid separator; the four-way reversing valve is provided with four pipe openings, namely the first pipe opening,the second pipe opening, the third pipe opening and the fourth pipe opening; a diameter-variable capillary tube is connected between the indoor heat exchanger and the outdoor heat exchanger; and theinner diameter of the end, connected with the indoor heat exchanger, of the diameter-variable capillary tube is larger than the inner diameter of the end, connected with the outdoor heat exchanger, ofthe diameter-variable capillary tube. According to the novel cooling and heating integrated heat pump air conditioning system, the diameter-variable capillary tube is adopted to replace the design ofa capillary tube and a one-way valve in a traditional heat pump air conditioning system, the structure is simple, the cost is low, and the number of assemblies is reduced compared with the traditional heat pump air conditioning system, so that the occupied space is smaller, the overall size of an outer shell of an air conditioner is smaller, split-type design is not needed, and the novel coolingand heating integrated heat pump air conditioning system is suitable for both household air conditioners and parking air conditioners with smaller spaces.

    本发明提供一种新型冷暖一体的热泵空调系统,包括压缩机、四通换向阀、室内换热器、室外换热器和气液分离器,所述四通换向阀有4个管口,分别为第一管口、第二管口、第三管口和第四管口,所述室内换热器和室外换热器之间连接有变径毛细管,所述变径毛细管与室内换热器连接的一端的内径比与室外换热器连接的一端的内径大。本发明采用变径毛细管代替传统家用热泵空调系统中的毛细管加单向阀设计,不仅结构简单,成本低,而且相对传统家用热泵空调系统减少了组件,使得占用空间减小,空调整体外壳尺寸减小,无需采用分体式设计,家用和空间较小的驻车空调都适用。
