Problems solved by technology

[0004] At present, the regenerator is usually installed separately. On the one hand, the structure of the vapor compression refrigeration system becomes complicated, and additional space is required to arrange the regenerator. On the other hand, the use of the regenerator as a separate component also increases the cost.

Abstract

The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration compressor shell, a refrigeration compressor and a refrigeration system. The refrigeration compressor shell comprises a shell body, wherein a compression cavity is defined by the shell body; the shell body is provided with a first inlet, a first outlet and a heat exchange runner, and the heat exchange runner and the compression cavity are located on the outer side and the inner side of the inner surface of the shell body correspondingly; the heat exchange runner is provided with a first end and a second end, the first end communicates with the first inlet, and the second end extends to communicate with the first outlet along a preset path relative to the first end. The refrigeration compressor comprises the refrigeration compressor shell. The refrigeration system comprises the refrigeration compressor. According to the refrigeration compressor shell, the refrigeration compressor and the refrigeration system, the heat exchange medium exchanges heat with the shell body and the refrigeration medium, so that the refrigeration medium can be at least subjected to heat regeneration, and the refrigeration compressor shell can also be used for cooling the refrigeration medium and a motor.

Description

technical field [0001] The present application relates to the technical field of refrigeration equipment, and in particular, to a refrigeration compressor housing, a refrigeration compressor and a refrigeration system. Background technique [0002] In the vapor compression refrigeration system, the refrigeration compressor lifts the refrigerant from low pressure to high pressure, and makes the refrigerant circulate continuously, so that the system continuously discharges the internal heat to the environment higher than the system temperature. [0003] In vapor compression refrigeration systems, regenerators are usually used to increase the temperature of the refrigerant, such as figure 1 As shown, the regenerator superheats the refrigerant flowing back to the refrigeration compressor, so as to improve the circulation efficiency and refrigeration capacity of the vapor compression refrigeration system where the refrigeration compressor is located. [0004] At present, the reg...
