Abstract
To control operating parameters of the compressor and ensure stable operation of the air conditioning system, a cooling medium control method for a multi-connected air conditioning system includes: acquiring current operating values of target parameters of the compressor during the operation of the compressor; calculating deviation degrees of the target parameters of the compressor according to the current operating values of the target parameters of the compressor and standard operating ranges of the target parameters of the compressor; and selectively adjusting an opening degree of the outdoor expansion valve or the indoor expansion valve based on the deviation degrees; where the standard operating ranges of the target parameters are operating ranges of the target parameters specified by a normal operating state of the compressor. Here the opening degree of the indoor expansion valve or the outdoor expansion valve is adjusted in real time according to parameters of the compressor.
