Abstract

The invention provides a refrigerant control unit which comprises a system liquid inlet pipe, an upper volume tank, a lower volume tank, a middle interlayer and a control valve, wherein the system liquid inlet pipe is educed from the lower volume tank; the upper volume tank and the lower volume tank are connected together through the middle interlayer; the upper volume tank is provided with an upper volume tank pipeline which is communicated with an inner cavity of the upper volume tank; the lower volume tank is provided with a lower volume tank pipeline which is communicated with an inner cavity of the lower volume tank; and the control valve comprises a refrigerant storage control valve and a refrigerant release control valve. The invention also provides an air conditioner refrigeration system which comprises the refrigerant control unit. The invention also provides two refrigerant cycle control methods. By using the refrigerant control unit, the air conditioner refrigeration system and the refrigerant cycle control methods provided by the invention, the problems that the system refrigerant cycle amount of the traditional air conditioner is difficult to control and the like can be solved.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a refrigerant control component, an air-conditioning and refrigeration system, and a refrigerant cycle control method. Background technique [0002] At present, air conditioners are widely used in various occasions of our work and life, providing us with a comfortable working and living environment. Ordinary air-conditioning and refrigeration systems include compressors, high-temperature heat source heat exchangers, throttling components, low-temperature heat source heat exchangers and piping systems. Under good working conditions, the system can guarantee stable and effective operation. The requirements for the operating range of the air conditioning system are increasing day by day, and the traditional air conditioner can no longer meet the market demand, especially for the air-cooled direct-cooling air-conditioning system, due to the limited ability to adjust the amount of circulatin...
