Abstract

The invention provides a multi-split air conditioner, a control method and device of the multi-split air conditioner and a storage medium. The method comprises the steps that after the air conditioneris started, for each of indoor units of the air conditioner, whether operation parameters of the indoor unit meet preset judgment conditions or not is judged; and if the operation parameters of the indoor unit meet the preset conditions, the opening degree of a throttling device of the indoor unit is adjusted according to the pipe temperature of the indoor unit and the constant humidity dew pointtemperature corresponding to the environment temperature of a room where the indoor unit is located. According to the scheme, the environment humidity of rooms where the different indoor units are located can be kept within the humidity range where people feel comfortable, and the comfort of the rooms where the indoor units are located during refrigeration of the multi-split air conditioner is improved.

Description

technical field [0001] The invention relates to the field of control, in particular to a multi-connected air conditioner and its control method, device and storage medium. Background technique [0002] Due to the different sizes of the internal units of the multi-connected air conditioner unit, the refrigerant flow control mainly depends on the capacity demand. At present, the capacity requirement generally only judges the cooling capacity requirement of the environment where the indoor unit is located, and the capacity requirement can only control the change of the compressor speed, and cannot effectively identify the actual output of the indoor unit in different rooms, which is equivalent to only controlling the total refrigerant Flow, cannot effectively control the split flow of each indoor unit, the flow ratio is different, and the capacity output is different, which will lead to a large difference in the outlet air temperature of different indoor units, and the humidity...
