The invention provides a multi-split air conditioner defrosting method and device, a multi-split air conditioner system and a readable storage medium. The method comprises the steps: judging the on-off state of indoor units, wherein the on-off state comprises shutdown; obtaining the capacity volumes of the indoor units and an outdoor unit after the state is judged, calculating the sum of the capacity volumes of the shutdown indoor units, and calculating the ratio of the sum of the capacity volumes to the capacity volume of the outdoor unit; and controlling the indoor units to enter corresponding defrosting modes according to the ratio. According to the multi-split air conditioner defrosting method and device, the multi-split air conditioner system and the readable storage medium, the state of each indoor unit of the multi-split air conditioner system can be analyzed, the actual use condition of the multi-split air conditioner system is represented through the capacity volume ratio related to the state of each indoor unit, and defrosting control is carried out according to the actual operation condition so that the defrosting control can be fit with the actual use condition of the multi-split air conditioner system, the indoor temperature is kept stable as much as possible during defrosting, and the thermal comfort experience of a user is guaranteed.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a multi-connection defrosting method and device, a multi-connection air-conditioning system and a readable storage medium. Background technique [0002] The multi-connected air conditioning system is a refrigeration / heating cycle system composed of at least one outdoor unit connected to multiple indoor units. When the multi-connected air-conditioning system is heating at low temperature, the heat exchanger of the outdoor unit is prone to frost, and the heat exchange efficiency drops sharply, which seriously affects the heat exchange effect. frost pattern. The traditional defrosting method is to evaporate and absorb the heat of the refrigerant in the heat exchangers of all indoor units, and then use the heat released by the discharged high-temperature and high-pressure gas to melt the frost layer of the outdoor heat exchangers; According to the actual usage cond...
