Abstract
The utility model discloses a refrigerant directly vaporizing type ground heat exchanger system. The ground heat exchanger system includes a ground pipe group, a heat pump unit and a user-side air-condition water system together formed by connecting a plurality of refrigerant directly vaporizing type spiral vertical ground pipes through pipelines. The refrigerant directly vaporizing type spiral vertical ground pipes are arranged in the soil. The ground pipe group and the heat pump unit adopt the same refrigerant and connect with the refrigerant to form a closed loop. The user-side air-condition water system is connected to a user-side heat exchanger for heat exchange. By adopting the refrigerant directly vaporizing type ground heat exchanger system in the utility model, the heat exchange efficiency is improved, thereby reducing the well drilling depth and floor space. The investment cost can also be reduced.
Description
Technical field
The utility model relates to geothermal system, more particularly, relates to the direct vaporation-type of refrigerant ground pipe laying heat-exchange system.
Background technology
Earth source heat pump obtains fast-developing the application in recent years as a kind of regenerative resource application technology of energy-conserving and environment-protective, has huge market potential.
At present, ground pipe laying heat-exchange system medium commonly used generally is water (or being added with anti-icing fluid), because the coefficient of heat transfer of water is less, therefore needs bigger drilling well pipe laying depth and floor space; And need jacket water systems such as cold water water pump, cooling water pipeline and valve fittings; In order to source pump in the refrigeration (heat) circulation refrigerant carry out heat exchange through heat exchanger; Therefore not only the initial cost cost is high, and the operation pump energy consumption is bigger, also has certain loss in efficiency.
The utility model content
To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides the direct vaporation-type of a kind of refrigerant ground pipe laying heat-exchange system, not only can improve heat exchange efficiency, with minimizing drilling depth and floor space, but also can reduce cost of investment.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The direct vaporation-type of this refrigerant ground pipe laying heat-exchange system comprises:
Be located at the buried nest of tubes in the soil, being linked to each other through pipeline by the perpendicular pipe laying of the direct vaporation-type spiral of a plurality of refrigerants constitutes;
Source pump comprises compressor, user side heat exchanger and switching-over expansion valve, links to each other successively and connects and composes closed circuit with buried nest of tubes through pipeline, and be set to a kind of refrigerant in the pipeline of source pump with in the buried nest of tubes;
The user side air-conditioner water system is connected to the user side heat exchanger to form heat exchange.
Described switching-over expansion valve is reversible switching-over expansion valve.
In technique scheme; The direct vaporation-type of the refrigerant of the utility model ground pipe laying heat-exchange system comprises to be located in the soil and buried nest of tubes, source pump and user side air-conditioner water system that linked to each other and constitute through pipeline by the perpendicular pipe laying of the direct vaporation-type spiral of a plurality of refrigerants; Buried nest of tubes and source pump adopt with a kind of refrigerant; And be linked to be closed circuit with it, the user side air-conditioner water system is connected to the user side heat exchanger to form heat exchange.Adopt this heat-exchange system not only can improve heat exchange efficiency,, but also can reduce cost of investment with minimizing drilling depth and floor space.
Description of drawings
Fig. 1 is the user mode sketch map of the direct vaporation-type of the refrigerant of the utility model ground pipe laying heat-exchange system.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also shown in Figure 1; The direct vaporation-type of the refrigerant of the utility model ground pipe laying heat-exchange system comprises buried nest of tubes 1, source pump and the user side air-conditioner water system of being located in the soil 5, and buried nest of tubes 1 is to be linked to each other through pipeline by the perpendicular pipe laying 6 of the direct vaporation-type spiral of a plurality of refrigerants to constitute; Source pump then comprises compressor 2, user side heat exchanger 3 and switching-over expansion valve 4, links to each other successively and connects and composes closed circuit with buried nest of tubes 1 through pipeline, and be set to a kind of refrigerant in the pipeline of source pump with in the buried nest of tubes 1; User side air-conditioner water system 5 is connected to user side heat exchanger 3 to form heat exchange, is used for to user's end air conditioner cold and hot water being provided.Described switching-over expansion valve 4 is reversible switching-over expansion valve 4, in order to realize the cold and hot conversion of winter heating, heat supply in summer.
Because the utility model has adopted spiral to erect pipe laying 6 on the one hand; And the mode that adopts refrigerant directly to evaporate, can increase heat exchange area, effectively improve heat exchange efficiency; Thereby can reduce pipe laying drilling depth and floor space; Through with the heat exchange of source, ground after refrigerant input to user side heat exchanger 3 by compressor 2, carry out heat exchange with the water of user side air-conditioner water system 5, thereby air conditioner cold and hot water be provided user's end; On the other hand, owing to need not cooling water indirect heat exchange system, reduced the cost of investment and the operation energy consumption of this circuits system.
In sum; Compared with prior art; The utility model can overcome existing aqueous medium indirectly the pipe laying heat-exchange system need the shortcoming of big heat-exchange system area and a whole set of cooling water medium pipeline system, thereby reduce pipe laying drilling depth and floor space, reduce water circuit system facility and energy consumption; Improved heat exchange efficiency greatly, effect very significantly.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
