本实用新型提供一种热泵空调系统，包括室内换热器、室外换热器、压缩机、四通阀、蓄热器和蓄热回路，所述四通阀分别与压缩机、室内换热器和室外换热器的吸气端和排气端连通;所述四通阀通过第一管道与压缩机的吸气端连接，所述蓄热器包裹在压缩机的外壁上，所述蓄热器与蓄热回路串联，蓄热回路与第一管道并联。本发明充分利用了室外换热器中的热量，大大提高了压缩机吸气端的吸气温度和制冷剂的焓值，从而大大提高了压缩机排气端的制冷剂温度，提高了热泵空调系统的制冷效率。
The utility model provides a heat-pump air-conditioning system, which comprises an indoor heat exchanger, an outdoor heat exchanger, a compressor, a four-way valve, a heat accumulator and a heat accumulation loop, wherein the four-way valve is respectively communicated with the air suction end and the air exhaust end of the compressor, the indoor heat exchanger and the outdoor heat exchanger; the four-way valve is connected with the air suction end of the compressor through a first pipeline; the heat accumulator is wrapped on the outer wall of the compressor; and the heat accumulator is connected to the heat accumulation loop in series, and the heat accumulation loop is connected with the first pipeline in parallel. The heat-pump air-conditioning system makes full use of heat in the outdoor heat exchanger and greatly increases the air suction superheat degree and the enthalpy value of the refrigerant at the air suction end of the compressor, thereby greatly improving the temperature of the refrigerant at the air exhaust end of the compressor and improving the defrosting efficiency of the heat-pump air-conditioning system.
