Abstract

The invention discloses a refrigerant storage device, a refrigeration circulation system and a control method thereof. The refrigerant storage device comprises a body used for containing the refrigerant, a refrigerant inlet is formed in the top of the body, a refrigerant outlet is formed in the bottom of the body; a refrigerating circulation system comprises a condenser and a throttling device, arefrigerant storage device is arranged between the condenser and the throttling device, the condenser is connected with the refrigerant inlet at the top of the body, the throttling device is connectedwith the refrigerant outlet at the bottom of the body; the refrigeration circulation system further comprises a compressor, an evaporator and an adjusting device used for adjusting the amount of refrigerant in the refrigerant storage device, the throttling device is arranged between the evaporator and the condenser, and the throttling device is connected with the refrigerant outlet at the bottomof the body through the adjusting device. According to the refrigerant storage device, the refrigerant flowing out of the refrigerant storage device is a liquid refrigerant, so that the gaseous refrigerant is remained in the liquid storage tank.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically relates to a refrigerant storage device, a refrigeration cycle system and a control method thereof. Background technique [0002] Due to the non-adjustable frequency of the existing fixed-frequency air conditioners, when the environmental load is low, the unit can easily reach the temperature set by the user and frequently start and stop, which not only wastes power, but also affects the life of the compressor and causes poor user experience. [0003] In the prior art, the capacity output is adjusted by adjusting the electronic expansion valve. When the temperature is close to the set temperature, the opening of the electronic expansion valve is increased to reduce the capacity output, so as to avoid frequent start-up and shutdown. However, this method It is easy to cause too much refrigerant to flow into the evaporator, resulting in incomplete evaporation, resultin...
