Abstract

The invention relates to a defrosting control method and device of an air conditioner system. The defrosting control method of the air conditioner system comprises the steps that when the air conditioner system needs defrosting, alternately controlling a part of condensers of an outdoor unit to be in the defrosting state and the other part of condensers to be in the normal work state at the same time is conducted; when it is determined that all the condensers complete defrosting, defrosting is ended, wherein the outdoor unit comprises at least two condensers. According to the defrosting control method of the air conditioner system, the air conditioner system adopts at least two condensers to alternately conduct defrosting, in this way, during defrosting, it is always guaranteed that at least one condenser is in the normal work state, the operation mode of an evaporator of a heating indoor unit keeps constant, an indoor draught fan does not stop, the indoor environment temperature is prevented from being lowered, and therefore the heating comfort and system reliability of the air conditioner system are effectively improved; and the situation that a user mistakes that an air conditioner breaks down can be avoided.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to a defrosting control method and device for an air conditioning system. Background technique [0002] When the temperature is low, when the air conditioning system is running for heating, the condenser of the outdoor unit of the air conditioner is prone to frost. If defrosting control is not adopted, it will seriously affect the heating effect of the air conditioner, resulting in a substantial attenuation of the heating capacity; and as time goes on, the frost will become thicker and thicker, which may damage the fan and cause the air conditioner to The damage will bring economic losses to users. [0003] In related technologies, when the air conditioner unit needs to defrost, the method used is to use the four-way valve to reverse the direction, the refrigeration internal unit continues to cool, the heating internal unit evaporator switches to cooling mode, an...
