Abstract

The invention relates to the technical field of air conditioners, and provides an air conditioner defrosting system, an air conditioner, and an air conditioner defrosting and heat recovery method. The air conditioner defrosting system comprises a heat exchange water pipeline, a water pump, a domestic hot water tank, a heat storage water tank and a controller; the domestic hot water tank is connected with a water inlet of the heat exchange water pipeline through a first switch valve, and the heat storage water tank is connected with a water outlet of the heat exchange water pipeline through a second switch valve; the heat exchange water pipeline, the heat storage water tank, the domestic hot water tank and the water pump are connected to form a first water circulation passage; and the controller is used for monitoring the running state of the air conditioner, controlling the water pump to be started and stopped according to the running state and controlling the first switch valve and the second switch valve to be on and off. According to the air conditioner defrosting system, when the air conditioner carries out low-temperature heating, the system can assist in defrosting, an air conditioner outdoor heat exchanger can rapidly and thoroughly achieve defrosting, and heating performance of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting system, an air conditioner, and an air conditioner defrosting and heat recovery method. Background technique [0002] In a low temperature and humid environment in winter, the heating of the air conditioner will cause frost on the outdoor heat exchanger, which will reduce the heat transfer capacity of the outdoor heat exchanger, and users will experience poor heating effect of the air conditioner. The traditional defrosting method is to control the switching of the four-way valve by detecting the temperature of the outdoor heat exchanger, so that the air conditioner converts heating into cooling, and the temperature of the outdoor heat exchanger rises to melt the frost on the fins of the outdoor heat exchanger. This method may have the problems of unclean defrosting and long defrosting time. Contents of the invention [0003] (1) Technica...
