Abstract

The invention discloses an air conditioning defrosting control method, which comprises the steps of detecting whether an outdoor heat exchanger (2) reaches a defrosting condition or not; if detecting that the outdoor heat exchanger (2) reaches the defrosting condition, controlling an air conditioner system to run and refrigerate, controlling a second throttle valve (8) to close, assisting a throttle device (4) in opening and defrosting the throttle device (4); controlling one part of refrigerant to sequentially pas through a bypass pipe (3) and a second indoor heat exchanger (6) and one part of refrigerant to sequentially pas through the outdoor heat exchanger (2), a first throttle valve (7) and a first indoor heat exchanger (5), converging the refrigerant flowing out of the second indoor heat exchanger (6) and the refrigerant flowing out of the first indoor heat exchanger (5) and then enabling the converted refrigerant to flow back to a compressor. According to the air conditioner defrosting control method, the problems of indoor temperature reduction and relatively large temperature fluctuation caused by an air conditioning system in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method. Background technique [0002] During low-temperature heating operation in winter, the longer the air conditioner runs, the more frost will form on the outdoor unit, which will seriously affect the heat exchange of the outdoor unit and reduce the indoor heating effect. At present, all products have automatic defrosting function, but the defect is that the defrosting During the process, the indoor unit is in the cooling mode and the fan is turned off. If the defrosting time is long or the defrosting is frequent, the indoor temperature will drop and the temperature will fluctuate greatly, affecting indoor comfort. Contents of the invention [0003] The object of the present invention is to propose a defrosting control method for an air conditioner to solve the problems in the prior art that the indoor temperature decre...
