Abstract
The invention discloses a direct refrigerant evaporating type buried pipe heat exchange system. The direct refrigerant evaporating type buried pipe heat exchange system comprises a buried pipe cluster, a heat pump unit and a user side air conditioning water system, wherein the buried pipe cluster formed by connecting a plurality of direct refrigerant evaporating type vertical spiral s through pipelines is buried in the soil. The buried pipe cluster and the heat pump unit utilize the same refrigerant and form a closed loop. The user side air conditioning water system is connected to a user side heat exchanger so as to form heat exchange. Heat exchange efficiency can be improved, drilling depth and occupation area are reduced, and investment cost can be reduced.
Description
Technical field
The present invention relates to geothermal system, more particularly, relate to refrigerant direct-evaporation-type buried pipe heat exchange system.
Background technology
Earth source heat pump is rapidly developed application in recent years as a kind of regenerative resource application technology of energy-conserving and environment-protective, has huge market potential.
At present, buried pipe 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 larger the Immersed tube degree of 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 by heat exchanger, therefore not only the initial cost cost is high, and the operation pump energy consumption is larger, also has certain loss in efficiency.
Summary of the invention
For the above-mentioned shortcoming that exists in the prior art, the purpose of this invention is to provide a kind of refrigerant direct-evaporation-type buried pipe 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 achieving the above object, the present invention adopts following technical scheme:
This refrigerant direct-evaporation-type buried pipe heat exchange system comprises:
Be located at the buried nest of tubes in the soil, being linked to each other by pipeline by the perpendicular pipe laying of a plurality of refrigerant direct-evaporation-type spirals consists of;
Source pump comprises compressor, user's side heat exchanger and commutation expansion valve, links to each other successively and connects and composes closed circuit with buried nest of tubes by pipeline, and be set to the same refrigerant in the pipeline of source pump with in the buried nest of tubes;
User's side air-conditioner water system is connected to user's side heat exchanger to form heat exchange.
Described commutation expansion valve is reversible commutation expansion valve.
In technique scheme, refrigerant direct-evaporation-type buried pipe heat exchange system of the present invention comprises is located at buried nest of tubes, source pump and user's side air-conditioner water system in the soil and that linked to each other and consist of by pipeline by the perpendicular pipe laying of a plurality of refrigerant direct-evaporation-type spirals, buried nest of tubes and source pump adopt the same refrigerant, and be linked to be closed circuit with it, user's side air-conditioner water system is connected to user's side heat exchanger to form heat exchange.Adopt this heat-exchange system not only can improve heat exchange efficiency, with minimizing drilling depth and floor space, but also can reduce cost of investment.
Description of drawings
Fig. 1 is the use view of refrigerant direct-evaporation-type buried pipe heat exchange system of the present invention.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with drawings and Examples.
See also shown in Figure 1, refrigerant direct-evaporation-type buried pipe heat exchange system of the present invention comprises buried nest of tubes 1, source pump and the user's side air-conditioner water system 5 of being located in the soil, and buried nest of tubes 1 is to be linked to each other by pipeline by the perpendicular pipe laying 6 of a plurality of refrigerant direct-evaporation-type spirals to consist of; Source pump then comprises compressor 2, user's side heat exchanger 3 and commutation expansion valve 4, links to each other successively and connects and composes closed circuit with buried nest of tubes 1 by pipeline, and be set to the same refrigerant in the pipeline of source pump with in the buried nest of tubes 1; User's side air-conditioner water system 5 is connected to user's side heat exchanger 3 to form heat exchange, is used for providing air conditioner cold and hot water to user's end.Described commutation expansion valve 4 is reversible commutation expansion valve 4, in order to realize the cold and hot conversion of winter heating, heat supply in summer.
Because one aspect of the present invention has adopted spiral to erect pipe laying 6, and the mode that adopts refrigerant directly to evaporate, can increase heat exchange area, the Effective Raise heat exchange efficiency, thereby can reduce pipe laying drilling depth and floor space, by with the heat exchange of source, ground after refrigerant input to user's side heat exchanger 3 by compressor 2, carry out heat exchange with the water of user's side air-conditioner water system 5, thereby provide air conditioner cold and hot water to user's end; On the other hand, owing to need not cooling water indirect heat exchange system, reduced cost of investment and the operation energy consumption of this circuits system.
In sum, compared with prior art, the present invention can overcome the shortcoming that the indirect buried pipe heat exchange system of existing aqueous medium needs larger 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, greatly improved heat exchange efficiency, effect is very remarkable.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
