In ripple outer tube.
In the use of the present invention, can be used alone ground water circulation pipeline or freon circulation line, only use underground water
Or electric energy carries out air conditioning.Underground water is used alone and carries out circularly cooling heating operation, i.e., it is former with the work of traditional water air-conditioning
It manages identical.Freon circulation is used alone and carries out cooling and warming operation, then it is identical as the working principle of conventional air-conditioning.
In the case where very hot, extremely cold or needs are efficiently adjusted, it can star two kinds of power of water power, i.e. realization workshop is dedicated
The most efficient operation mode of water power air-conditioning.
When refrigeration operation, ground water circulation pump enables the cold water in underground water source enter underground water by ground water circulation pipeline
Surface air cooler, fan drive air-flow to pass through underground water meter cooler, cold air are released and reaches refrigeration effect, then underground water is suitable again
Inner tube in heat exchanger is entered by ground water circulation pipeline, then returns to underground water source, completes the operation of water circulation system.
At the same time, high pressure gaseous freon is discharged in freon compressore, is entered by freon circulation line and is changed
In the outer tube of hot device, the underground water in freon and inner tube is enabled to carry out heat exchange, i.e., takes away room air using underground water and exchange
Generated heat, loses in underground water source.Refrigerant becomes high-pressure liquid after completing heat dissipation, is subtracted by capillary-compensated
Pressure makes refrigerant become low-pressure liquid, flows into freon surface air cooler, by fan, absorbs the heat in indoor air, finally
Back in freon compressore, achieve the purpose that refrigeration in cycles.
It is similar when carrying out principle when heating operation and process to refrigeration, unlike freon under the valve action that commutates,
It is opposite when flow direction is with refrigeration.Freon is compressed into high pressure gaseous under low-pressure gaseous state, by freon compressore, is sent into
In freon surface air cooler, radiated in room by fan, freon becomes liquid after heat dissipation, then by through capillary-compensated
Decompression, returns in the outer tube of heat exchanger, when freon circulates in outer tube, carries out hot friendship with the underground water in inner tube of heat exchanger
It changes, takes away the cooling capacity of indoor discharge, be then discharged in underground water source.Last freon back in freon compressore, week and
It renews and achievees the purpose that heating.
The above described is only a preferred embodiment of the present invention, being not that the invention has other forms of limitations, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.Without departing from the technical solutions of the present invention, to the above embodiments according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within the protection scope of technical solution of the present invention.
