Problems solved by technology

During this process, the suction temperature fluctuates violently, which is caused by the incomplete evaporation of the refrigerant in the evaporator. Fluctuations in the suction temperature make the performance of the entire system unstable, and the reliability of the compressor will decrease.

Abstract

The application relates to an air conditioner with automatic control of suction temperature, which belongs to the technical field of air conditioners. This application includes: an auxiliary electric heating device, which is arranged in the return air channel of the indoor unit of the air conditioner. After the auxiliary electric heating device heats the return air of the indoor unit of the air conditioner during cooling, the heated return air flows through the evaporator to pass through the air conditioner. Increase the evaporation load of the evaporator to reduce the suction temperature fluctuation. Through this application, it is helpful to ensure the stability of the suction temperature while ensuring the refrigeration, thereby ensuring the stability of the system performance and improving the operation reliability of the air conditioner.

Description

technical field [0001] The application belongs to the technical field of air conditioners, and in particular relates to an air conditioner with automatic control of suction temperature. Background technique [0002] Most of the existing household and commercial air conditioners are based on the working principle of the vapor compression refrigeration cycle, and the refrigeration is performed through the interaction of the evaporator, compressor, condenser and throttling structure. In the actual design process, the factors to be considered are not only the selection of these four components, but also the matching of performance. When performing performance matching, factors to be considered include cooling capacity within a reasonable range, superheat within a reasonable range, and so on. During this process, the suction temperature fluctuates sharply, which is caused by the incomplete evaporation of the refrigerant in the evaporator. The fluctuation of the suction temperatu...
