Embodiment Construction

[0017] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0018] Such as figure 1 , image 3 As shown, generally the depth H of the mine 01 from the ground is about 1000 meters, and the ambient temperature under the mine 01 is too high, so the vapor compression refrigeration system 02 is required for cooling during underground operations. The fresh air introduced through the fresh air pipe 05 exchanges heat with the evaporator 4 of the refrigeration system; the cooling water drawn from the ground 03 through the water pipe 04 cools and exchanges heat with the condenser 2, and the temperature of the water after heat exchange rises to hot water. Due to the limited space in the well, it is usually impossible to store a large amount of water, and the temperature in the well is high, so the heat of the hot water is not easy to dissipate, so this part of hot water often needs to be pumped back to the ground by t...

Abstract

The invention discloses a hydraulically-driven refrigerating system. The hydraulically-driven refrigerating system comprises an evaporator, a condenser and a hydraulically-driven compressor. A water inlet of a hydraulic drive pump in the hydraulic drive compressor is communicated with high-energy water flow, and a water outlet of the hydraulic drive pump is communicated with a water inlet of the condenser. The water power of the cooling water is used for driving the compressor of the refrigerating system to work, and meanwhile the cooling water is used for cooling the condenser. In other words, the compressor of the refrigerating system does not need to consume power, an electric cabinet does not need to be arranged, and the electrical safety problem of the compressor is solved. And at night, the hot water after heat exchange can be sent back to the ground to be used as domestic hot water and geothermal heating hot water. The low electricity price at night is utilized, water is recycled, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to fluid conveying equipment, in particular to a cooling system used in underground mines which does not need electricity but is only driven by water power. Background technique [0002] The application of local refrigeration equipment in mines can improve the management level of mine heat hazards, improve the working environment, protect the health of employees, and improve labor production efficiency, which is of great significance to the realization of safe and efficient production in mines. Such as figure 1 As shown, the condenser of the vapor compression refrigeration system 02 in the mining face of the mine 01 needs to be cooled from the ground 03 through the water pipe 04 for cooling. Down, it has a higher water pressure. In addition to the cooling effect, this top-down cooling water from the ground can also be used to drive the motor of the compressor in the vapor compression refrigeration system 02, instead of electrici...
