Embodiment 1

[0026] Embodiment 1: each of the condenser 1 and the evaporator 11 of this embodiment is one, which is a system for one supply; The equipment 13 for environmental heat exchange constitutes the heat exchange subsystem of the evaporator, which continuously provides heat for the evaporation of the liquid working medium in the evaporator, and at the same time completes the task of cooling the position of the evaporator; the condenser 1, the liquid receiver 20. Regulating valve 19, liquid working medium main pipe 18, n (1≤n≤50) gravity potential energy recovery compressors 6, step-down gas-liquid separator 17, expansion valve 16, liquid separator 15, liquid equalizing pipe 14. Evaporator 11, evaporator gas collection main pipe 9, gas working medium transport main pipe 10, gas compressor 4, condenser gas distribution main pipe 3 and gas equalization pipe 2 constitute the heat pump (or heat pipe) working medium internal circulation sub-pipe The system continuously transports the heat...

Embodiment 2

[0028] Embodiment 2: The evaporator heat exchange subsystem and the condenser heat exchange subsystem of this embodiment are the same as in Embodiment 1, and the composition and working process of the heat pump (or heat pipe) working medium internal circulation subsystem are also basically the same as in Embodiment 1. , but a small circulation system of liquid working medium composed of a liquid reservoir 24, a solution pump 25, and a liquid working medium supply pipe 26 is installed on the side of the evaporator. This small circulation system can improve the phase change heat process in the evaporator , improve heat transfer efficiency.

[0029] In this embodiment, each component is first attached figure 2 As shown in the installation, vacuumize the internal circulation subsystem of the heat pump (or heat pipe) and fill it with an appropriate amount of circulating fluid, then adjust the regulating valve to an appropriate opening, and start the heat exchange subsystem of the ...

Embodiment 3

[0030] Embodiment 3: The heat exchange subsystem of the evaporator and the heat exchange subsystem of the condenser in this embodiment are the same as in Embodiment 1, and the basic composition of the internal circulation subsystem of the heat pipe is similar to that of Embodiment 1, except that there is no gas compressor. Therefore, only the heat pipe circulation process can be realized.

[0031] In this embodiment, each component is first attached image 3 As shown in the installation, vacuumize the internal circulation subsystem of the heat pipe working medium and fill it with an appropriate amount of circulating working medium, then adjust the regulating valve to an appropriate opening, start the evaporator heat exchange subsystem and the condenser heat exchange subsystem, and then Start operation; after a certain period of time, the heat exchange subsystem of the evaporator, the internal circulation subsystem of the heat pipe and the heat exchange subsystem of the condens...

Abstract

The invention belongs to the technical field of energy source engineering and relates to a vertical remote cold and hot energy transporting system device combining heat pipe circulation and heat pump circulation. A gaseous working medium positioned in a condenser on the uppermost part of the system transmits heat energy to ambient air of a position at which a refrigerating equipment or a condenser is connected with the gaseous working medium, and then the ambient air generates phase change and flows into a liquid accumulator after being converted into a liquid working medium; after the flow rate of the liquid working medium in the liquid accumulator is adjusted by an adjusting valve, the liquid working medium flows towards the direction of an evaporator along a vertical pipeline, falls to enter a gravitational potential energy recycling gas compressor and converts a pressure produced by the gravitational potential energy into rotation mechanical energy serving as a power source and enables a gas in a gas working medium main pipe to flow upwards after being pressurized; and vertical remote cold and hot energy transporting is sequentially and circularly completed. The vertical remote cold and hot energy transporting system device has the advantages of large energy transporting distance, high heat efficiency, safe and stable transmission process, reliable equipment and device principles, novel structure, convenient operation and the like, and is suitable for transporting cold and hot energy in the vertical direction.

Description

Technical field: [0001] The invention belongs to the technical field of energy engineering, and relates to a high-efficiency energy-saving system device in which a heat pipe cycle and a heat pump cycle are combined for long-distance cold and heat energy transportation in the vertical direction. Background technique: [0002] With the increase of mining depth, the rock temperature gradually increases, and the heat damage problem of the mining and tunneling working face environment becomes more and more serious. The temperature of many working faces exceeds 28°C, and some are as high as 34°C, and the humidity is as high as 90%. At present, the deepest mine in the world is the deep horizontal gold mine in western South Africa, with a depth of 3,618 meters, the depth of the Kola Gold Mine in India, which is 3,231 meters, the depth of No. 2060 meters, and there are more than 60 mines in South Africa alone that are more than 1,000 meters long. Deep wells of nearly a kilometer suc...
