Abstract

The invention belongs to the technical field of intelligent household appliances, and in particular relates to a refrigerant flow control method, device, electronic equipment and an air conditioner. The present invention aims to solve the problem of inconsistent supply air temperature of existing air conditioners with multiple evaporators. The present invention determines the valve opening information by acquiring the temperature information and according to the temperature information. The valve opening information is used to represent the opening degree of each branch valve in the branch system connected to each evaporator, and according to the valve opening information, the valve opening degree information is used to control the opening degree of each branch valve in the branch system. The opening degree of the diverter valve so that the temperature difference of each evaporator is less than the preset temperature threshold. Since the valve opening information representing the opening degree of the diverter valve corresponding to each evaporator is determined by the temperature information of each evaporator, according to the valve The opening information adjusts the diverter valve, which can reduce the temperature difference between the evaporators, thereby improving the consistency of the air supply temperature corresponding to each evaporator, solving the problem of inconsistent air supply temperature in different zones, and improving the cooling / control of the air conditioner. Thermal efficiency.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a refrigerant flow control method, device, electronic equipment and an air conditioner. Background technique [0002] At present, with the continuous advancement of technology, air conditioners with multiple evaporators are more and more popular due to their rapid cooling / heating advantages. The air conditioner with multiple evaporators can drive the refrigerant to circulate between the condenser and multiple evaporators through the refrigerant pipeline under the action of the compressor, and release and absorb heat with the change of the refrigerant state to realize air conditioning. for cooling or heating purposes. [0003] However, in actual use, when an air conditioner with multiple evaporators is supplying air in zones, due to the different air volume of each air supply zone, the temperature between multiple evaporators will also be different, resulting...
