Abstract

The embodiment of the invention provides an air conditioner for achieving defrosting without the reversing of a four-way valve required. According to the technical scheme of the air conditioner provided by the embodiment of the invention, the air conditioner comprises a compressor, a four-way valve, an outdoor heat exchanger, a first throttling device, an indoor front heat exchanger, a second throttling device and an indoor rear heat exchanger which are in pipeline connection with one another sequentially; the air conditioner further comprises a defrosting solenoid valve; one end of the defrosting solenoid valve is in pipeline connection with the compressor; and the other end of the defrosting solenoid valve is in pipeline connection with the outdoor heat exchanger.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of air conditioning, and in particular to an air conditioner. Background technique [0002] During heating operation in winter, due to the low outdoor ambient temperature, the surface of the outdoor heat exchanger is often below 0°C, so the surface will gradually frost, and the heating capacity of the unit will gradually decrease as the frost thickens. , the temperature of the indoor air outlet gradually decreases, and at this time, defrosting is required. [0003] Traditional household air conditioners or most fluorine system central air conditioner manufacturers use reverse cycle defrosting with four-way reversing valve, that is, defrosting operation is equivalent to cooling operation, and has the following disadvantages: At this time, the indoor unit performs anti-cold wind processing, stop heating, affecting comfort, the heat exchanger of the indoor unit acts as an evaporator to di...
