Abstract

A refrigerant storage device proposed by the present invention includes an upper shell, a lower shell, a sealing ring, a sealing piece, a hollow nut, a hollow screw, a cylindrical spring, and a piston device, which can store and adjust the refrigerant and the pressure of the refrigerant. adjust. The refrigeration system with the refrigerant storage device proposed by the present invention is respectively provided with a first refrigerant storage device and a second refrigerant storage device after the compressor and the second heat exchanger, and the first and second refrigerant storage devices Adjust the refrigerant in the system to optimize the efficiency of the system, and this refrigeration system with a refrigerant storage device can expand the refrigeration capacity of the compressor, reduce the start and stop of the compressor, reduce energy consumption, and can also improve the refrigeration system. Cooling accuracy, it can be used in occasions where the fluctuation frequency of heat load is high and the fluctuation frequency and fluctuation range are relatively clear, and has high working efficiency.

Description

technical field [0001] The invention relates to the field of heat exchange devices, in particular to a refrigerant storage device and a refrigeration system with the refrigerant storage device. Background technique [0002] A general refrigeration system consists of a compression device, a condenser (heat exchanger), an expansion device, an evaporator (heat exchanger), a separation device, etc. The compression device converts electrical energy into mechanical energy, and changes the thermodynamic state of the refrigerant through mechanical force , and then the refrigerant creates a low temperature environment inside the evaporator (heat exchanger). In a refrigeration system, the largest power consumer is usually the compressor. The heat load of the cooling target often has certain fluctuations. For the occasions where the heat load has a high fluctuation frequency and a relatively clear fluctuation range, there are mainly two coping strategies for the existing refrigeration...
