Source, ground and water source heat pump system are mainly connected to form by pipeline by ground heat exchanger, source pump and three parts of end system.Wherein source pump and end system are quite ripe, and underground heat-exchanger device absorbs energy from underground by the mode of heat exchange.Because underground situation is ever-changing, extremely complicated, it is maximum in the world uneven plastid, therefore, how underground heat-exchanger device can suit measures to local conditions, steady in a long-term from the underground required energy of heat pump that obtains, simultaneously not influencing environment again as much as possible, is the key problem in technology that water source, earth-source hot-pump system are installed.In winter, the liquid working substance in the pipeline of earth source heat pump is taken underground heat out of, imports in the building by system then, simultaneously at the underground cold that stored, in order to summer grade; In summer, earth source heat pump is derived heat in building, is conducted into undergroundly by heat exchanger, stores heat simultaneously, uses in order to the winter.Earth source heat pump all can provide high-quality cold and heat air throughout the year reliably, for we build an indoor environment as snug as a bug in a rug.
Not all earth-source hot-pump system all is economical rationality, because drilling cost may account for more than 50% of whole system initial cost, the mounting cost of earth-source hot-pump system is higher at present, compare with 500～800 yuan/standard ton of electricity refrigeration, natural gas heating system, 600～1000 yuan/standard ton of earth source heat pump (1 standard ton 1=3.516KW) obviously is high, and be 5～8 years its payoff period; And the maintenance of earth-source hot-pump system is comparatively difficult, and this can influence its use to a certain extent.
Summary of the invention
The purpose of this utility model is to provide a kind of earth source heat pump that utilizes civil air defense constructions and installations to do low-temperature receiver or thermal source, and higher with the mounting cost that the solution prior art exists, payoff period is long, safeguards the comparatively problem of difficulty.
The technical solution of the utility model is: comprise the ground heat exchanger, circulating pump unit and the user's heat exchanger that are connected to closed circuit successively by pipeline, in this closed circuit system, be filled with liquid thermal conductivity media, it is characterized in that: described ground heat exchanger is laid in the space in bomb shelter of civil air defense constructions and installations or is embedded in the underground of this bomb shelter, this ground heat exchanger is made up of the heat exchange pipeline serial or parallel connection, and its input and output interface is connected with user's heat exchanger with described circulating pump unit by pipeline.
Described heat exchange pipeline is by two parallel compositions, and this heat exchange pipeline interconnects the location by radiating fin or connector; Be provided with the heat exchange pipeline ring flange at the two ends of each this heat exchange pipeline, end at two these heat exchange pipelines is equipped with and two ring flange butted U shape tube connector, is provided with the tube connector ring flange corresponding with described heat exchange pipeline ring flange at the two ends of this U-shaped tube connector.
Described heat exchange pipeline adopts the high tubing of heat exchange efficiency, and these tubing comprise steel-plastics composite pipe, cylinder concrete pipe, glass reinforced plastic pipe, stainless steel tube, ductile iron pipe, plastic tube, pvc pipe, PE pipe, PPR pipe or PB pipe.
Described liquid thermal conductivity media comprises water, calcium chloride water, sodium-chloride water solution, glycol water and alcohol water blend.
The syndeton of described heat exchange pipeline serial or parallel connection is that mantle fiber connects, flange connects, socket joint connects, collude groove connections, loose joint connection, welding, hot melt connection or be connected.
The utility model has the advantages that: utilize cold (heat) source, existing urban human preventing engineering bomb shelter as earth source heat pump, in the hole, lay heat exchange pipeline, in pipeline, feed heat transferring medium and absorb the fixed geothermal energy resources of relative weighing apparatus cool in summer and warm in winter in the civil air defense constructions and installations bomb shelter, offer the circulating pump unit, realize the normal operation of earth-source hot-pump system.Because bomb shelter normal temperature is bigger again and length, avoid earth source heat pump to get the technology of underground heat and the restriction of economized form by well-digging, reduce the financial cost and the technical difficulty of earth source heat pump greatly, repair and replacement at any time.
