Background technology
At present air-cooled heat pump central air-conditioning, air source hot pump water heater are that when defrosting in the winter time, system commutates by four-way change-over valve, becomes refrigerating state by the state of heating with the defrost of reverse operation mode, remove frost after, turn back to again and normally heat state.
The tower heat-exchanger rig of some that also have in addition is to gather thermal source in air, offer the water cooling heat pump unit, what this type of tower used in the winter time is the tower heat exchanger of large-scale integral formula, when gathering air heat source, its Defrost method: a kind of is constantly to add anti-icing fluid winter in open cooling tower water, to keep heat transferring medium solution to be in all the time liquid flow and heat exchange state, another kind of scheme is outside the metallic recuperator of enclosed tower, frequently spray hot water or anti-icing fluid, to keep the outer surface frost-free of heat exchanger.
But there are following problem in the Defrost method of above source pump or tower and principle:
The energy consumption of the mode of the reverse defrost of tradition cross valve commutation type is high, the solution Defrost mode of the large-scale heat exchange columns that similar cooling is tower or adopt the outer spray mode of large-scale enclosed tower, also because solution is diluted or drifts about volatilization and waste is excessive, the uneconomical also not environmental protection of system's when operation.A system is comprised of 1,2 large-scale enclosed tower, and the bulk metal heat exchanger structure that adopts goes defrost if stop a tower machine operation, can affect to a great extent the continuity that gathers thermal source.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of ground source heat defrosting array heat exchange columns, reduces energy consumption, and the continuity that gathers thermal source is good.
The technical solution of the utility model is, a kind of ground source heat defrosting array heat exchange columns, comprise heat exchange columns main body and Cooling and Heat Source circulation water main, be provided with the heat exchange module that a plurality of one-tenth arrays are arranged in the heat exchange columns main body, described Cooling and Heat Source circulation water main is connected to each heat exchange module by a Cooling and Heat Source circulation minute water water inlet pipe; Heat exchange module comprises the heat exchange module skeleton in shell, the shell, the air duct of cover top portion and the blower fan in the air duct, and at the heat exchange module skeleton a plurality of heat exchange units with import and outlet is installed, and links to each other by tube connector between each heat exchange unit; Also be provided with geothermal source circulation water main in the heat exchange columns main body, and geothermal source circulation water main is connected to heat exchange unit in each heat exchange module by a geothermal source circulation minute water water inlet pipe; Described heat exchange module also comprises the first electric T-shaped valve and the second electric T-shaped valve, connect the Cooling and Heat Source circulation on the first electric T-shaped valve and divide water water inlet pipe, geothermal source circulation minute a water water inlet pipe and the feed liquor pipeline that is connected with the heat exchange unit import, connect the drain pipe that the Cooling and Heat Source circulation divides water outlet pipe, geothermal source to divide the water outlet pipe and be connected with the heat exchange unit outlet on described the second electric T-shaped valve.
The described heat exchange unit outside is provided with a plurality of shower nozzles that coupled together by the nozzle connecting adapter, and is provided with water-accepting basin at outer casing bottom, and the end that described nozzle connecting is taken over is connected with water-accepting basin through water jet pump; Can clean, lower the temperature to the heat exchange unit heat exchanging unit of spraying water, can also when temperature is low, spray anti-icing fluid and prevent that heat exchange unit from freezing.
Described shell is provided with air inlet and the air duct end face is provided with air outlet, and wind enters from the air inlet of heat exchange unit, carries out going out from air duct end face air outlet after the heat exchange through in the heat exchange unit.
Described heat exchange module housing diameter is greater than the air duct diameter, and at the outer air inlet/outlet dividing plate that is arranged with of the air duct of outer casing top surface.
This structure is connected the geothermal source circulating water pipe with ground source heat water, when carrying out normal heat exchange, divide the path of water water inlet pipe to open the Cooling and Heat Source circulation of the first electric T-shaped valve and the second electric T-shaped valve, and with the path blockade of the geothermal source of the first electric T-shaped valve and the second electric T-shaped valve circulation minute water water inlet pipe, cold/heat source liquid circulates in heat exchange unit and carries out the heat conduction, and opens blower fan and accelerate the heat conduction; When the needs defrosting, close the path of the Cooling and Heat Source circulation minute water water inlet pipe of the first electric T-shaped valve of a heat exchange module in the heat exchange columns and the second electric T-shaped valve, and divide the path of water water inlet pipe to open the geothermal source circulation of the first electric T-shaped valve and the second electric T-shaped valve, this heat exchange module is carried out defrosting; After the defrosting of this heat exchange module is finished, close the first electric T-shaped valve of this heat exchange module and the geothermal source circulation of the second electric T-shaped valve and divide the path of water water inlet pipe, and divide the path of water water inlet pipe to open the Cooling and Heat Source circulation of the first electric T-shaped valve and the second electric T-shaped valve; Close again the path of the Cooling and Heat Source circulation minute water water inlet pipe of the first electric T-shaped valve of next heat exchange module and the second electric T-shaped valve, and divide the path of water water inlet pipe to open the geothermal source circulation of the first electric T-shaped valve and the second electric T-shaped valve, and heat exchange module of exchanging successively in the thermal tower according to this order carries out defrosting.
As known from the above, the utlity model has following advantage:
1, monoblock type changes into and disperses little module: a system of array heat exchange columns is comprised of the small modules of a plurality of dispersions, the compactedness of each module is good, and floor space is little, and each module can be distinguished one by one circulating defrosting, little to systematic influence, can satisfy the requirement of system's continuous acquisition thermal source.
2, the anti-icing fluid defrosting becomes the ground source heat defrosting: owing to adopted these cheap geothermal energy resources of ground source heat water, circulating-heating heat exchange unit in each module has reduced the operating cost of system.
3, the defrosting of outer spray solution changes the closed type hot defrosting into: because anti-icing fluid is not used in the outside, avoided spray solution to float loose everywhere and affect surrounding environment, fundamentally solved environmental issue.
4, change many thermals source into by single air heat source: during construction foundation working, to take full advantage of foundation ditch and stake hole and lay thermal source collection heat exchanger tube, gather underground heat, do not need other punching, reduced the geothermal engineering cost, as the outer supplemental heat source of air heat source, improved the quality of thermal source, also improved the efficiency of unit simultaneously:
5, disperse the array layout, discharge air-flow and inlet air flow space out farther, are difficult for short circuit, and heat transfer effect is better.
