As shown in Fig. 2, heat-collection well 11 and inverted well 13 of the invention opens up the underground around wind and rain playground at a certain distance,
Heat-collection well 11 passes through fine sand layer and grit layer reaches boulder bed, and the temperature in stratum changes less throughout the year.Water body is in heat-collection well 11
During permeating in soil between inverted well 13, heat exchange is carried out, the filtering of five through filter 111 layer filter structure
Afterwards, it is stored into heat-collection well 11, water resource heat pump 2 can be directly entered and carry out heat exchange, reduce heat exchange link together, the heat in water body
Energy utilization rate is higher.
Winter air temperature is lower, and water body draws the heat in the stable soil of temperature during flowing into heat-collection well 11,
Water temperature rises.At this point, opening A control valve 14, B control valve 15, C control valve 33 and D control valve 34, E control valve 16, F control are closed
Valve 17, G control valve 35 and H control valve 36 processed.High temperature water body after filtering in heat-collection well 11 through filter 111, is followed by first
Ring pump 12 extracts, and after flowing through 211 heat release of the first heating coil pipe, into inverted well 13, heat-collection well 11 and inverted well 13 are utilized for recharge
The height of water accelerates the infiltration and heat exchange of water body, realizes the circulation of water body.Thermal energy coupled in evaporator 21 first for hot plate
First time heat exchange is completed between pipe 211 and evaporation coil 213；Water resource heat pump 2 is done work by compressor 22, will be in evaporator 21
It is transmitted to condenser 23 after having absorbed the heat-conducting medium heating pressurization of heat, passes through the first heat absorption coil pipe coupled in condenser 23
231 complete second of heat exchange with the ring disk 233 is condensed, after the heat-conducting medium after heat transfer cooling passes through the decompression of expansion valve 24, again
It flows into evaporator 21 to absorb heat again, forms heat pump heat supply circulation.Air conditioning terminal 3 will be inhaled by the first heat absorption 231 heat exchange of coil pipe
Recirculated water after taking heat is transported to the heat release into wind and rain playground of fan coil 31, circulating water cooling by second circulation pump 32
Condenser 23 is returned afterwards to absorb heat again, forms the heating cycle of air conditioning terminal 3.Air in wind and rain playground absorbs fan coil 31
Bring heat, reaches temperature rise effect.
Summer air themperature is higher, and heat is received by the stable soil of temperature during water body flows into heat-collection well 11, water temperature
Decline.At this point, closing A control valve 14, B control valve 15, C control valve 33 and D control valve 34, E control valve 16, F control valve are opened
17, G control valve 35 and H control valve 36.Low temperature water body after filtering in heat-collection well 11 through filter 111, is pumped by first circulation
12 extract, and after flowing through the heat absorption of the second heat absorption coil pipe 232, into inverted well 13, heat-collection well 11 and inverted well 13 utilize water level for recharge
Drop accelerates the infiltration and heat exchange of water body, realizes the circulation of water body.The second heat absorption coil pipe 232 that thermal energy couples in condenser 23
First time heat exchange is completed between condenser coil 233；Water resource heat pump 2 does work, and exothermic low temperature will be completed in condenser 23
The expanded valve 24 of heat-conducting medium passes to evaporator 21 after being depressured, and passes through 212 He of the second coil pipe of coupling in evaporator 21
Second of heat exchange is completed between evaporation coil 213, the heat-conducting medium after heat absorption heating back flows back into after the pressurization of compressor 23
The heat release again of condenser 23 forms heat pump refrigeration cycle.Air conditioning terminal 3 will be dropped by the 212 heat exchange heat release of the second heating coil pipe
Recirculated water after temperature is transported to the heat in the classification absorption of coil pipe 31 wind and rain playground by second circulation pump 32, returns after heating
The heat release again of evaporator 21 forms the refrigeration cycle of air conditioning terminal 3.Heat in wind and rain playground in air is inhaled by fan coil 31
Take-up is walked, and achievees the effect that cooling.
According to the above technical scheme, the present invention is water source heat by the heat that thermal energy acquisition device absorbs water body in heat-collection well
Pump stablizes energy supply, and the sufficient water source collected between multiple heat-collection wells and inverted well carries out heat exchange by stratum, through heat-collection well
Filter filtering after enter in heat-collection well after, be directly entered water resource heat pump exchange heat, then pass through fan unit in air conditioning terminal
Pipe everywhere in heat input to wind and rain playground, will be realized to be exchanged with cold and hot inside wind and rain playground, meets the confession on wind and rain playground
Heat and refrigeration demand, while heat exchange efficiency is high, cheap.
It should be noted that preferred embodiment above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, those skilled in the art should understand that: it is still
Can modify to technical solution documented by previous embodiment, or some or all of the technical features are carried out etc.
With replacement；And these are modified or replaceed, technical solution of the embodiment of the present invention that it does not separate the essence of the corresponding technical solution
Range should all cover within the scope of the claims and the description of the invention.
