Problems solved by technology

[0006] Second, non-economic
However, no matter which method is used, the pipeline system is complicated and the pipeline investment is huge. In such a scheme, the pipeline investment cost will account for more than half of the entire refrigeration system. Although the ground centralized type is easy to discharge condensation heat, the pipeline system is too long and Complex, secondly, difficult hydraulic balance
Both the downhole type and the upper and lower combined type have difficulties in discharging condensation heat and high discharge costs
For example, the patent number is 200420002464.8 "Low-temperature gushing water cooling device for mine air-conditioning", which is difficult to operate

Embodiment 1

[0034] Such as figure 1 As shown, the temperature difference type mine air-conditioning cold and heat source energy system provided by the present invention includes a fluid medium, a refrigerator device (10), a heat pump central hot water device (1), a low-temperature liquid storage device (6), an evaporator device (7 ), an evaporation-condensation low-temperature heat exchange device (2) and pipeline systems (3), (9) connected to the above-mentioned devices in a closed cycle in sequence, wherein (3) is a high-pressure heat preservation pipeline.

[0035] During operation, open the valve of the low-temperature liquid storage tank (6), and the liquid ammonia enters the evaporator device (7) along the pipeline, and after exchanging cold and heat with the brine from the mine working face after absorbing heat, the liquid ammonia Ammonia is converted into gaseous ammonia; at the same time, the brine in the brine pipeline (8) is transported to the high-temperature working face aft...

Embodiment 2

[0037] Such as figure 2 As shown, on the basis of the cycle flow diagram provided in Example 1, the heat pump central hot water device is removed, which simplifies the system flow; when the high-temperature heat in the downhole is transferred to the evaporation-condensation low-temperature heat exchange device (2) In the process, the heat is transferred to the condenser device in the refrigerator by the refrigerator (10), and the heat is directly discharged into the atmosphere by the condensation device of the refrigerator (10), so that the heat in the well can be guaranteed to be absorbed It is continuously discharged from the underground to achieve the goal of eliminating heat damage in high-temperature mines.

Embodiment 3

[0039] Such as image 3 As shown, on the basis of the cycle flow diagram provided in Example 1, the refrigerator is removed, and a single cycle process of thermopump heat pump is directly formed by the heat pump central hot water device and the fluid medium ammonia cycle system. When the high temperature heat in the well is is transferred to the evaporation-condensation low-temperature heat exchange device (2), and the heat is directly transferred from the evaporator in the heat pump central heating device (1') to the water storage tank in the heat pump central heating device; if the water storage tank When the hot water is full, the heat from the downhole is directly discharged into the atmosphere by the standby condenser device in the heat pump central hot water device (1'), so that the heat from the downhole can be continuously discharged from the downhole. Achieve the goal of eliminating heat damage in high-temperature mines. In such a cycle, the underground high-temperatu...

Abstract

The invention relates to a temperature differential mine air conditioner system, which comprises a fluid medium, a refrigerator, a compressor device, a heat pump central water heater, a low-temperature liquid storage device, an evaporation heat exchanger device, an evaporation-condensation heat exchange device, a condensation heat exchange device and a pipeline system for tightly and circularly connecting the devices in sequence. The temperature differential mine air conditioner system is characterized in that the evaporator heat exchange device is arranged underground; the condensation heat exchange device is arranged at the position on the ground and/or underground, which is economic and easy to discharge condensation heat, preferably the position on the ground; and the fluid medium circularly flows in the pipeline system. The system solves the problems of difficult delivery, complicated pipeline, high investment and insusceptible discharge of the condensation heat of a secondary refrigerant of the mine air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and in particular relates to a mine air-conditioning and refrigeration technology. Background technique [0002] With the increase of mine mining depth and the continuous improvement of mechanization, high temperature heat damage in deep mines has become one of the major problems restricting coal mine safety production. The limit mining depth of mines in the future will depend on the development level of mine cooling technology and equipment. my country's coal mines have been extending downward at a rate of about 10 meters per year. [0003] The high-temperature and high-humidity underground working environment will make people feel uncomfortable, thereby reducing labor production concerns, increasing the accident rate, and affecting the safe production of the mine. When people are engaged in heavy physical labor under high temperature conditions, the cooling capacity ...
