A kind of twin-well underground heat switch

Technical field

The utility model belongs to heat-exchanger rig field, is specifically related to a kind of twin-well underground heat switch.

Background technology

The traditional direct groundwater abstraction of water air conditioner water circulating pump source is to water evaporation tube, by heat exchange fan by the temperature distribution of water in living environment, because the temperature four seasons of underground water source are constant in the scope of 16-19 degree Celsius, therefore can play the effect that freeze summer, heat winter.But be subject to just the temperature range restriction of underground water, within the temperature regulating power of this air-conditioning aspect heating also only limits to certain scope, to use, make troubles.And, old-fashioned water air-conditioning is after long-time use, near underground water source water air-conditioning underground heat-exchanger device, a large amount of heat or cold air that absorbs air-conditioning discharge, ground water temperature is progressively identical with external environment, the temperature difference diminishes, and air-conditioning regulates the effect of ambient temperature also significantly to weaken by ground water temperature.Meanwhile, at other, utilize the fields such as the water circulation heat exchange that water resource heat pump, industrial products and the equipment of underground water heat exchange cools, also have same problem.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of twin-well underground heat switch, can carry out efficient water circulation heat exchange.

The utility model solves the technical scheme that its technical problem adopts: a kind of twin-well underground heat switch is provided, comprise body, body internal circulation system, water inlet pipe, outlet pipe and underground water source, one end junctor body-internal-circulation system of water inlet pipe, the other end of water inlet pipe is installed water-circulating pump and is inserted in underground water source; One end junctor body-internal-circulation system of outlet pipe, the other end of outlet pipe takes back underground water source and is communicated with water inlet pipe; Connecting downhole heat exchanger between water inlet pipe and outlet pipe, down-hole heat exchanger is positioned at below the dynamic water level of underground water source; Underground water source comprises main shaft and auxiliary shaft, and down-hole heat exchanger is placed in main shaft; Main shaft is connected by pipeline with auxiliary shaft.

Water pump is set in main shaft, and water pump connects auxiliary shaft by pipeline, and the water of main shaft can be injected to auxiliary shaft.

Water pump is arranged in the shallow-layer waters within the scope of the following 0.5-1.5 rice of main shaft horizontal plane.

The beneficial effects of the utility model are:

1, underground water source comprises main shaft and auxiliary shaft, between main shaft and auxiliary shaft, has proportional spacing, and down-hole heat exchanger is placed in main shaft; Water pump is set in main shaft, water pump connects auxiliary shaft by pipeline, and the water of main shaft can be injected to auxiliary shaft, the sealing internal circulation system being formed by water inlet pipe, outlet pipe and body internal circulation system, not affected by external atmosphere pressure, the required drive that makes to circulate reduces, and interior recirculated water can be not contaminated, lossless, more traditional water air-conditioning is more energy-conservation.Down-hole heat exchanger dispels the heat after certain hour in main shaft, and water pump injects auxiliary shaft by the high-temperature water in main shaft, and the underground water that surrounding temperature is lower can refill into main shaft, maintains the constant low temperature of main shaft, makes the heat exchange efficiency of down-hole heat exchanger higher.

2, water pump is arranged in the shallow-layer waters within the scope of the following 0.5-1.5 rice of main shaft horizontal plane, and the moderate variation with horizontal plane in position is adjusted, this makes water pump can absorb all the time the less upper strata hot water of density in main shaft, and in time by these hot water circuit in auxiliary shaft, the steady temperature that has effectively kept main shaft, has guaranteed heat exchange efficiency.

3, the utility model is simple in structure, flexible and convenient to use and energy-efficient, is not only applicable to water air-conditioning, can also be widely used in the fields such as the water circulation heat exchange that water resource heat pump, industrial products and equipment cools, cost of manufacture is low, and Practical Performance is good, suitablely in the industry cycle popularizes.
