Abstract

The invention discloses an air conditioning defrost method and device. The air conditioning defrost method comprises the following steps of detecting outdoor environment temperature; detecting heat exchanger temperature at an outdoor side of an air conditioner; selecting a defrost mode of the air conditioner according to the outdoor environment temperature and the heat exchanger temperature, wherein the defrost mode comprises multiple defrost modes preset according to conditions met by the outdoor environment temperature and the heat exchanger temperature; controlling the air conditioner to defrost according to the selected defrost mode. Through the air conditioning defrost method and device provided by the invention, the problem that the defrost mode cannot be adjusted according to the frost condition due to a single air conditioning defrost mode in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of air conditioners, and in particular, to a method and device for defrosting an air conditioner. Background technique [0002] The operation of the air conditioner in a low temperature environment often leads to frost on the outdoor heat exchanger, which requires us to defrost the outdoor heat exchanger under certain circumstances. In the traditional defrosting method, when the outdoor side of the air conditioner meets the defrosting conditions, the refrigerant commutation cycle is usually performed, and the compressor performs work and discharges the high-temperature refrigerant to the outdoor side heat exchanger to transfer heat through the high-temperature refrigerant in the heat exchange tube. Defrost outside the tube. [0003] However, the inventor found that although such a defrosting method has a relatively good defrosting effect, the defrosting method is single, and the defrosting method cannot be ad...
