Repeatable and quick assembly-disassembly type cooling system and special pipeline connecting device

Abstract

The invention relates to a repeatable and quick assembly-disassembly type cooling system and a special pipeline connecting device. The cooling system comprises a compressor (1), a condenser (2), a reservoir (3), a dry filter (4), an expansion valve (5) and an evaporator (6). The cooling system is characterized in that: a first pipeline connecting device (7) is arranged between the dry filter (4) and the expansion valve (5); a second pipeline connecting device (8) is arranged between the evaporator (6) and the compressor (1); a first solenoid valve (9) is arranged on a pipeline between the first pipeline connecting device (7) and the dry filter (4); the first pipeline connecting device (7) is connected with a connecting position between the second pipeline connecting device (8) and the compressor (1) through a pipeline (11); ports of two pipeline connecting devices are respectively connected with a miniature vacuum pump (12) through a third solenoid valve (14); and control input ends of the two pipeline connecting devices (8) are connected with a miniature hydraulic station (13). The cooling system can be provided with the evaporator under the cooled environment, and can reduce the manufacturing cost and use cost greatly by adopting a direct cooling mode.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a repeatedly and quickly assembled and disassembled refrigeration system, and a special pipe connection device for the refrigeration system. It belongs to the technical field of refrigeration equipment. Background technique [0002] Refrigeration devices in the prior art are generally a closed system composed of compressors, condensers, expansion valves, evaporators, connecting pipes and other components. The refrigerant flows in the system. Due to the strong permeability of the refrigerant, it is easy to leak , so after the refrigeration system is assembled and put into use, the system cannot be disassembled; however, some special processes in the industry require the refrigeration device to combine the high-pressure part composed of the compressor and the condenser with the high-pressure part composed of the expansion valve and the evaporator during the non-working period. The low-pre...
