Air conditioning system control method and device, storage medium and air conditioning system

Abstract

The invention provides an air conditioning system control method and device, a storage medium and an air conditioning system. The method comprises the steps that the optimal supercooling degree range of operation of the air conditioning system is determined; the current supercooling degree of the air conditioning system is obtained; according to the comparison result of the current supercooling degree and the optimal supercooling degree range, whether the refrigerant circulation amount in the air conditioner system meets the operation requirement or not is determined; and if it is judged that the refrigerant circulation amount in the air conditioning system does not meet the operation requirement, an air supply electromagnetic valve is controlled to be opened, the opening degree of a first electronic expansion valve and the opening degree of a second expansion valve are adjusted, and the refrigerant circulation amount is increased or decreased. According to the air conditioning system control method, the air conditioning system with the refrigerant filling amount according to the maximum connecting pipe length standard can regulate and control the refrigerant circulation amount in the system, so that the refrigerant circulation amount always meets the operation requirement of the system; therefore, the problem that the refrigerant needs to be additionally added into the system according to stages during after-sales debugging of the air conditioning system is avoided.

Description

technical field [0001] The disclosure belongs to the technical field of air conditioning, and in particular relates to an air conditioning system control method, device, storage medium and air conditioning system. Background technique [0002] After the split-type air conditioner is sold to the customer, due to different customer needs or different building installation environments, the length of the connecting pipe of the indoor and outdoor units may be different. The length of the pipe and the additional amount per unit length specified in the installation manual are used to calculate the total additional amount, and then manual operation is performed through external equipment (including refrigerant tanks, electronic scales, and pipelines used to connect refrigerant tanks and unit valves), so that Adding refrigerant, increasing the efficiency of after-sales installation will generate additional after-sales installation costs, causing customer dissatisfaction.

Problems solved by technology

[0002] After the split-type air conditioner is sold to the customer, due to different customer needs or different building installation environments, the length of the connecting pipe of the indoor and outdoor units may be different. The length of the pipe and the additional amount per unit length specified in the installation manual are used to calculate the total additional amount, and then manual operation is performed through external equipment (including refrigerant tanks, electronic scales, and pipelines used to connect refrigerant tanks and unit valves), so that Adding refrigerant, increasing the efficiency of after-sales installation will generate additional after-sales installation costs, causing customer dissatisfaction

At the same time, there will also be inaccurate addition due to improper operation, which will affect the performance of the air conditioner and the reliability of the compressor.
