Abstract

The invention provides a multi-split defrosting method and device, a multi-split air conditioner system and a readable storage medium. The multi-split defrosting method comprises the steps that the state of an indoor unit is judged, and the state comprises shutdown and unmanned startup; the capacity volumes of the indoor unit and an outdoor unit are obtained after the state is judged, the sum of the capacity volume of the indoor unit which is shut down and the capacity volume of the indoor unit which is not started up is calculated, and the ratio of the sum of the capacity volumes to the capacity volume of the outdoor unit is calculated; and the indoor unit is controlled to enter a corresponding defrosting mode according to the ratio. The state of each indoor unit of the multi-split air conditioning system can be analyzed, the actual use condition of the multi-split air conditioning system is represented through the capacity volume ratio related to the state of each indoor unit, 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 conditioning 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. In the traditional defrosting method, the refrigerant in the heat exchangers of all indoor units evaporates and absorbs heat uniformly, and then uses the heat released by the discharged high-temperature and high-pressure gas to melt the frost layer of the outdoor heat exchangers; In the actual use of the syste...
