Problems solved by technology
[0003] As people's requirements for the operation effect of air-conditioning systems are increasing day by day, traditional air conditioners can no longer meet market demand, especially for multi-connected air-conditioning units, due to their relatively large amount of refrigerant and the relatively large variability of indoor operating loads. The requirements for the control of the amount of refrigerant in the system are even higher
When the indoor operating load varies greatly, the control of the refrigerant volume of the multi-connected system cannot meet the requirements, and the operation effect of the multi-connected air conditioner unit will be affected, thereby affecting the user's comfortable experience

The invention discloses a multi-connected refrigerant control method, device, air conditioner and storage medium. The method includes: obtaining the coil temperature, the temperature of the refrigerant cooling plate and the temperature of the power module board; when the temperature of the refrigerant cooling plate and the temperature of the coil When the temperature difference is smaller than the first preset temperature threshold, the multi-connected refrigerant is controlled according to the temperature of the refrigerant cooling plate and the temperature of the power module board. The present invention realizes obtaining the current operation state of the multi-connected system according to the temperature of the coil tube, the temperature of the refrigerant cooling plate and the temperature of the power module board, and then effectively adjusts the multi-connected system, so that the control of the amount of refrigerant in the multi-connected system meets the requirements and ensures the multi-connected air conditioner unit The running effect improves the user experience.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a multi-connected refrigerant control method and device, an air conditioner and a storage medium. Background technique [0002] The multi-connected air conditioner unit is an annular pipe network system composed of a compressor, an electronic expansion valve, other valve bodies and a series of pipelines. Since the multi-split unit can intelligently adjust the temperature and precisely control the temperature, and each indoor function can be adjusted independently, it can meet the needs of different spaces and different air-conditioning loads. In addition, the multi-line also has the advantages of energy saving and convenient installation. Therefore, the use of multi-line is more and more widely used. [0003] As people's requirements for the operation effect of air-conditioning systems are increasing day by day, traditional air conditioners can no longer meet m...
