Abstract

The invention provides a multi-split air conditioning system, a defrosting control method and system, and a computer readable storage medium. The multi-split air conditioning system comprises an innerair duct communicated with the indoor, an outer air duct communicated with the outdoor, an air outlet branch part provided with two air outlets which are communicated with the inner air duct and theouter air duct respectively, and electric heating equipment arranged at the air outlet communicated with the inner air duct. When the multi-split system enters a defrosting mode, an indoor unit fan operates at a set rotating speed, cold air passing through an indoor side heat exchanger is divided into two parts at the air outlet branch part, one part of the cold air enters the outer air duct and flows to the outdoor, and the other part of the cold air enters the inner air duct and flows to the indoor after being heated by the electric heating equipment. In the defrosting process, the indoor unit fan operates, and the defrosting time is shortened; and meanwhile, hot air can be blown to the indoor side, and the use comfort and experience of a user are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a multi-connected system, a defrosting control method, a system, and a computer-readable storage medium. Background technique [0002] The multi-line system is a refrigeration cycle system composed of one or more outdoor units connected to multiple indoor units. When the multi-split system operates in heating mode in winter, due to the low outdoor temperature and the heat exchanger of the outdoor unit acts as an evaporator to release cooling capacity, the surface of the heat exchanger of the outdoor unit gradually forms frost, and the heat exchange effect on the outside will deteriorate. As the running time increases, the frost layer accumulates thicker and thicker, which leads to worsening heat exchange effect of the outdoor unit, and correspondingly worse heating effect of the indoor unit, which seriously affects the performance of the unit. Therefore, it is n...
