It connect to form third closed loop with the supporting medium end of heat pump unit evaporator 6-2, the first closed loop goes out refrigeration duty 7-5
Heat transfer give the second closed loop, the second closed loop transfers heat to third closed loop, third closed loop
This heat is being passed into ground heat exchanger 1 by heat pump unit 6, ground heat exchanger 1 by this partial heat store to
In surface soil.
The system is the workflow of earth's surface mine Waste Heat Reuse circuit heat supply: opening the first valve 4 and first circulation pump
5, by the heat transfer absorbed from mine ventilation system 3 to ground heat exchanger 1, ground heat exchanger 1 exists high-low pressure heat exchanger 2
This partial heat is rotated to heat pump unit 6, heat pump unit 6 will pass to hot water heating load 9- after the conversion of this partial heat again
1 and/or thermic load 8-3.
In non-heating season, in fact it could happen that the larger situation of mine cooling load, cooling system heat exhaust is more than earth's surface at this time
The heat storage capacity of soil can open cooling tower 6-5 auxiliary heat dissipation, guarantee the safe and highly efficient operation of heat pump unit 6.At this point, opening
Cooling tower 6-5 auxiliary heat dissipation workflow: the 4th circulating pump 6-6 and the 5th valve 6-7 is opened, makes to open cooling tower 6-5 and heat pump
Unit condensation side carries out heat exchange, reaches cooling effect, and adjust the 5th valve 6-7, the open degree of the 6th valve 1-2 is adjusted
The flow of accumulation of heat and cooling tower 6-5 auxiliary heat dissipation.
In heating season, the workflow of deep downhole system is identical as non-heating season.On ground open second circulation pump 8-1,
Second valve 8-2 and third valve 8-4 forms loop, and the condensation with heat pump unit 6, which is surveyed, to exchange heat, to residential quarter heat supply.It opens
Third circulating pump 9-2 and the 4th valve 9-3 forms loop, exchanges heat, is used to residential quarter heat supply with the condenser side of heat pump unit 6
Water.The 5th circulating pump 1-1, the 6th valve 1-2 and three-way diverter valve 1-3 are opened, so that the evaporation side and underground pipe of heat pump unit 6
The formation loop of heat exchanger 1, for extracting the heat that non-heating season is stored in earth's surface.Remaining valve and pump are closed.So far, non-confession
The heat that warm season is stored in earth's surface passes through above-mentioned loop transfer to residential quarter.
Heating season deep-well refrigeration duty reduces, and heat pump system is mainly satisfied with the domestic hot-water of mining area house at this time and life supplies
It is warm to need.According to the needs that the heating demand of mining area house and hot water load measure, all or part of heat of Deep mine ventilation loop
It is used for ground heating system by heat pump unit, and the heat implementation that non-heating season is stored in earth's surface is extracted by ground heat exchanger
The heat supply heat pump cycle of winter house.
Heat pump unit evaporator refrigerating medium uses glycol water, and condenser side circulatory mediator is water, and heat pump unit is set
It is placed on ground.System can be achieved underground by the switching of valve and cool down throughout the year, ground summer cooling supply, winter heat supply, long-term supplying hot water
Etc. functions.
It is extracted when needing using heat pump techniques by thermal energy storage low-grade under mine in earth's surface.Reduce China
Environmental pollution caused by traditional mining area winter long-term heat supply of north cold area and large-scale non-renewable resources disappear
Consumption, during this system use, the operating cost of system well below the use charge use for using traditional heating equipment and is set
Standby maintenance expense, has greatly saved heat cost, meanwhile, this system can be effectively by the temperature of working surface of deep well
It is down to standard operating temperature, improves working environment, supply hot water system is added, improves quality of the life, has been reduced or remitted because improving miner
Living and working environment and ancillary cost expense, have very big economic benefit.The traditional mining area well of this system enhancement
Lower Climatic regionalization problem and heat recycle problem, take full advantage of geothermal energy, embody sustainable development air-conditioning reason
It reads.
