Example Embodiment

[0011] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] like figure 1 As shown, the present invention mainly includes a compressor 1, an outdoor heat exchanger 2, a throttling device 3, an indoor heat exchanger 4, an outdoor machine fan 5, and an outdoor machine casing 6. When the air conditioner is running in summer, the exhaust pipe of compressor 1 is connected to the inlet of outdoor heat exchanger 2, the outlet of outdoor heat exchanger 2 is connected to the inlet of throttling device 3, and the outlet of throttling device 3 is connected to indoor heat exchanger 4 The inlet of the indoor heat exchanger 4 is connected to the suction pipe of the compressor 1; when the air conditioner is running in winter, the exhaust pipe of the compressor 1 is connected to the inlet of the indoor heat exchanger 4, and the outlet of the indoor heat exchanger 4 is connected to The inlet of the throttling d...

Abstract

The heat pump type air-cooled air conditioner utilizing the afterheat of compressor includes mainly refrigerant loop comprising compressor, outdoor heat exchanger, throttle unit and indoor heat exchanger; and outdoor blower capable of changing its rotation direction in winter. In winter and while the room is heated, the outdoor blower rotates in reverse direction, so that air from outdoor flows first through the compressor to exchange heat with the compressor casing to raise temperature and then through outdoor heat exchanger to exchange heat with refrigerant. The present invention recoversthe heat of compressor to raise the air intake temperature, improve the low temperature working performance of the air conditioner and the winter operation performance of the air conditioner.

Description

Technical field: [0001] The invention relates to a heat pump type air-cooled air conditioner, in particular to a heat pump type air-cooled air conditioner which utilizes waste heat of a compressor to improve heating capacity under low temperature conditions, and belongs to the technical field of refrigeration and air conditioning. Background technique: [0002] Heat pump air conditioners are used for cooling in summer and heating in winter, which is an energy-saving heating method. However, when the ambient temperature is lower than 5°C, the outdoor evaporator of the air-cooled air conditioner is prone to frost, resulting in deterioration of heat transfer performance. Therefore, when the air conditioner operates in the heating mode for a period of time, it must switch to the cooling mode through the four-way reversing valve for defrosting. After reversing, the original outdoor heat exchanger is changed from an evaporator to a condenser, and the high-temperature refrigerant ...
