Abstract

The invention discloses an air conditioner. The air conditioner comprises a compressor, a first heat exchanger, a coolant pump and a second heat exchanger, wherein the compressor, the first heat exchanger, the coolant pump and the second heat exchanger communicate with one another in sequence to form a coolant circulation loop; the air conditioner further comprises a flash evaporation bypass one-way valve; one end of the flash evaporation bypass one-way valve communicates with the outlet of the coolant pump; the other end of the flash evaporation bypass one-way valve communicates with the inlet of the first heat exchanger; when the flash evaporation bypass one-way valve is opened, the compressor is shut down; and the coolant pump, the flash evaporation bypass one-way valve and the first heat exchanger form an internal loop. The invention further discloses a control method of the air conditioner, and a computer readable storage medium. The air conditioner disclosed by the invention caneliminate the phenomenon of flash evaporation, caused by sudden reduction of the pressure of a coolant, of the air conditioner after the compressor is shut down and the coolant pump runs.

Description

technical field [0001] The present invention relates to the technical field of air conditioner manufacturing, in particular to an air conditioner, a control method thereof, and a computer-readable storage medium. Background technique [0002] The trend of moving data center plants to the north poses an important challenge to the stable operation of precision air conditioners in low temperature environments. Currently, the outdoor temperature of data centers established in Europe and Northeast China can reach below -40°C. Precision air conditioners mainly solve the problem of low-temperature refrigeration through the way that the refrigerant pump and the compressor work in turn. When the outdoor temperature is higher than the set temperature, the compressor is used to run; when the outdoor temperature is lower than the set temperature, the refrigerant pump is used for cooling. The key to this refrigeration method is that when the compressor is switched to the operation of t...
