Problems solved by technology

[0007] When the refrigeration unit is installed underground, it is necessary to excavate a special large-scale equipment chamber. The refrigeration equipment must meet the requirements of underground explosion-proof standards, compact equipment, and high reliability. However, ordinary refrigeration units with mature technology cannot meet these requirements. In addition, refrigeration The key problem when the unit is placed underground is that the condensation heat i

Embodiment Construction

[0032] The refrigerating system provided by the present invention can simultaneously realize surface refrigerating and efficiently transport cooling underground.

[0033] The technical scheme that the present invention takes and its working principle:

[0034] A refrigeration system for mine cooling, the main equipment (except the evaporator) is placed on the well, and a chamber is set near the shaft of the return air shaft to place the evaporator and underground chilled water preparation and circulation equipment; the refrigeration adopts a vapor compression refrigeration cycle system, and the refrigeration Agent R717, evaporator and condenser all adopt plate heat exchanger, the compressor adopts screw type, and the throttling element is a slender tube; mine drainage is used to cool the cooling water.

[0035] Its working principle is: Refrigerant R717 is compressed in the Inoue compressor to become a high-temperature and high-pressure gaseous refrigerant, enters the Inoue co...

Abstract

The invention discloses a refrigeration system for mine cooling. A compressor (1) is connected with a condenser (2) and mounted on a mine; the compressor (1) and the condenser (2) are connected with an evaporator (4) mounted underground through a restricting element (3), so that a refrigeration cycling system is formed; the refrigeration cycling system is filled with a refrigerating agent; the condenser (2) is connected with a closed heat exchanger (5) through a cooling water circulating pump (6) and by pipelines, so that a cooling water circulation system is formed; the cooling water circulation system is filled with cooling water; and the evaporator (4) is connected with an air cooler through a frozen water circulating pump (7), so that a frozen water circulation system is formed, and the frozen water circulation system is filled with frozen water.

Description

technical field [0001] The invention relates to a refrigeration system for mine cooling, in particular, the evaporator of the refrigeration system is placed underground in the mine, and other refrigeration components such as compressors, condensers, and cooling equipment are located on the ground of the mine, and the expansion valve is replaced by a slender tube. system. Background technique [0002] With the increase of mining depth in mines (coal mines, metallurgical mines) and the continuous improvement of mining mechanization, high-temperature heat damage in mines has become one of the major problems restricting underground safety mining. Relevant experts believe that the limit mining depth of mines in the future will depend on mines. The development level of cooling technology and equipment. The high temperature and high humidity environment not only seriously endangers the health of the human body, but also threatens the normal production. Because the human body is i...
