I.e. for heat pump unit 4 with air energy thermal source 3 equivalent to outdoor machine of air-conditioner, this is conventional design, is no longer repeated with regard to details on border.It is described defeated
Outlet 5 includes the condenser being made of heat exchanger tube, can carry fan, as heating follower, can also be arranged in water, as
Hot water generator.
There is the first water-flow circuit 61, only when in the attemperater 12 between the attemperater 12 and well 21
When water temperature is less than the water temperature in well 21, first water-flow circuit 61 works, and makes attemperater 12 and the water in well 21
Body circulation flows.Specifically, which has an intake pipe and a return pipe, and intake pipe can be by well
Water in 21 is pumped into attemperater 12, and return pipe then makes the water in attemperater be back to well；In order to circulate the first water
Circulation waterway is formed in circuit 61, one-way circulation pump can be concatenated in the intake pipe, and solenoid valve is concatenated in return pipe,
When needing water circulation, while open the circulation pump, solenoid valve, otherwise both close；Certain this kind of water-flow circuit 61
Also there is more design method, it is very easy to implement in HVAC field, and the place of the creation main points of non-invention.
The embodiment one of the finned heat exchanger is as shown in figure 3, heat exchange fin 71, snakelike heat exchange tube including interfixing
72nd, fan（It is not shown）, the snakelike heat exchange tube 72 connects the heat pump unit 4 and output terminal 5.The attemperater 12 and wing
There is the second water-flow circuit 62 between piece heat exchanger, there is one section of heat exchanging segment 621 in second water-flow circuit 62, this is changed
Hot arc 621 is made of heat exchange copper tube, and in the finned heat exchanger, heat exchange fin 71 is fixed on side by side with snakelike heat exchange tube 72
On, heat exchanging segment 621 is obtained heat can be transferred in snakelike heat exchange tube 72 by metal conduction.
Water body in the attemperater 12 can circulate in second water-flow circuit 62, certainly, also by
Circulating pump is realized with solenoid valve；And if only if the output terminal 5 is more than setting value with the circumstance of temperature difference residing for the finned heat exchanger
When, second water-flow circuit 62 works.
In addition, in first water-flow circuit 61, the second water-flow circuit 62, not with the well 21, attemperater
12nd, the part of finned heat exchanger heat exchange is formed by insulating tube, is lost in avoid the midway of heat.
Above-mentioned solar energy, underground heat and air energy integrated using heat pump system in heating, first by heat pump unit 4 from institute
State in the air where finned heat exchanger and extract heat, and be discharged into the output terminal 5；When the output terminal 5 is changed with fin
When circumstance of temperature difference residing for hot device is more than setting value, that is, when heating efficiency is relatively low, make the attemperater of the solar source
Water body in 12 heats finned heat exchanger by the second water-flow circuit 62, so that it is guaranteed that two of heat pump unit 4 are changed
The temperature difference between hot junction is in lower value, to ensure heating efficiency；In addition, when air energy, solar energy are insufficient, cause to protect
When water temperature in reservoir 12 is down to relatively low, then by first water-flow circuit 61, make the water body in well 21 and insulation
Water circulation in water tank 12 neutralizes, so that the heat that underground water is rich in is delivered to attemperater 12, and is finally delivered to
Finned heat exchanger；The system by step by step according to condition draw air energy, solar energy, geothermal energy method, the various energy is all existed
Just it is called when needing most, so that the various energy can obtain the utilization of peak efficiency, largely saves
Natural energy resources.On the other hand, due to only setting one shorter and fixed compressor operating circuit, hardware in the system
Cost is relatively low, and working performance is relatively stablized.
For the embodiment two of the finned heat exchanger, what is different from the first embodiment is that second water-flow circuit 62
In heat exchanging segment 621 be arranged at the finned heat exchanger snakelike heat exchange tube 72 inside, it is coaxial with the snakelike heat exchange tube 72
Extension；So that the heat of heat exchanging segment 621 is directly passed to the refrigerant in snakelike heat exchange tube 72, and avoid in finned heat exchanger
Fan brushing under, largely spill into external environment, this improves the utilization rate of heat to the full extent.Specifically, such as Fig. 4
Shown, the end of the snakelike heat exchange tube 72 connects the first port 81 of a three-way device 8, the second port of the three-way device 8
The 82 connection heat pump units 4, the 3rd port 83 by the heat exchange copper tube of the heat exchanging segment 621 for being pierced by, to realize that water is recycled back to
Road and refrigerant circulation loop it is mutually isolated.The program is simple in structure, easy to assembly, easy to implement.
In addition, for the well 21, one embodiment as shown in Fig. 2, the top of the well 21 be built with it is a piece of
Collect hot-zone；The area of the collection hot-zone is not less than 4 times of well cross-sectional area, equivalent to more than 2 times of a diameter of well diameter；
The collection hot-zone includes submerging soil 24, and surrounds the heat preservation tank 22 of well 21；The notch of the heat preservation tank 22 elevates above the soil, and
Covered with transparent glass 23 on the notch；The heat carrier being made of metallic plate is lined with soil in the heat preservation tank 22
25, the heat carrier 25 extends to the lower part of well.According to the program, the collection hot-zone on 21 top of well can absorb in large area
Solar energy, is allowed to be transferred in well；Due to being isolated between collection hot-zone and the external world by transparent glass 23, extraneous air-flow
Smaller for the heat influence in collection hot-zone, the heat through transparent glass 23 is largely accumulated in the soil in collection hot-zone,
And absorbed via heat carrier 25 by well water, so that in geothermal energy under the situation quickly extracted, the water temperature of well water is unlikely to fast
Speed declines.The lower surface of the transparent glass 23 can also be coated with infrared reflection film, to suppress the heat of soil with infra-red radiation
Form escapes.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification for being made, equivalent substitution, should all be included in the protection scope of the present invention.
