Description
Technical field
The utility model relates to ground source heat pump technology heat-insulation system field, mainly is the heat preservation technology to earth-source hot-pump system, is specifically related to a kind of heat-insulation system and heat-insulation system structure of mainly being made by polyurethane heat insulation material.
Background technique
Adopt the ground source heat pump technology heating and refrigerating; The form of utilizing that belongs to renewable energy sources; Can practice thrift a large amount of high-grade energy (electric energy or fire coal etc.), China is carrying out scale energetically and is using, but because the characteristic limitations of current ground source heat pump technology itself; Delivery all has thermal loss to user side or water tank, and air conditioning water or delivery also exist cold and hot loss to user's end.Therefore, earth source heat pump central refrigerating heating system must be paid attention to the insulation of heating power course of conveying, otherwise the heat-energy losses of course of conveying can cause the heating and refrigerating temperature can not satisfy user's life requirement.
At present; The earth source heat pump heat-insulation system has the material of various insulations, and there are weakness such as thermal conductivity is high relatively, heat insulation and preservation effect is poor, water proofing property difference in traditional pipe insulation material (like rubber and plastic, perlite etc.), and has only one deck thermal insulating material to wrap on the interior conduit on traditional heat-insulation system structure; Water absorption rate is again than higher; Waterproof is poor, causes corrosion after long-time, so that influences thermal conductivity and adiabatic intensity.The cold and hot loss of traditional heat-insulation system is bigger, does not have the maximum using renewable energy sources, and energy-saving effect decreases.
The model utility content
The utility model purpose provides a kind of earth source heat pump heat-insulation system; Comprise earth source heat pump unit, air conditioning terminal, domestic hot-water's user side, contain the polyurethane heat-insulation structure hot water storage tank and between the pipeline that contains the polyurethane heat-insulation structure that connects; It is characterized in that: between geothermal heat pump air-conditioner unit and the air conditioner user end, between earth source heat pump hot water unit and the hot water storage tank and the pipeline that is connected between hot water storage tank and the domestic hot-water's user side be the pipeline heat insulation structure that contains polyurethane; With the hot water storage tank that heat pump unit is connected with pipeline is the hot water storage tank insulating structure that contains polyurethane; Its thermal insulation property is excellent, can effectively reduce the cold and hot loss in the cold and hot amount course of conveying of earth-source hot-pump system.
In order to solve the above problems, the technological scheme that the utility model adopts is:
The pipeline heat insulation structure is divided into three layers from the inside to the outside, is respectively interior pipe, polyurethane insulation coating, outer tube; The hot water storage tank insulating structure is divided into three layers from the inside to the outside, is respectively hot water storage tank internal layer, polyurethane insulation coating and external protection.
During the field fabrication heat-insulation system, outer tube or water tank external protection have material hole and relief opening.
The material of interior pipe and hot water storage tank internal layer can be metal, plastics or other material, has the transudation that has completely cut off empty G&W; Disposable injection polyurethane stock solution foaming in the polyurethane insulation coating cavity that to be foaming machine form between the internal layer of the interior pipe of pipeline and outer tube or hot water storage tank and outer protective layer and the thermal insulation layer that forms; Polyurethane insulation coating and pipeline inner and outer pipes, water tank internal and external layer adhesion driving fit; Have that thermal conductivity is little, intensity is high, adiabatic, sound insulation, performance such as fire-retardant, cold-resistant, anticorrosion, can effectively reduce cold and hot loss; The material of outer tube or water tank external protection can be metal, plastics or other material; During the field fabrication heat-insulation system; Pipe or water tank internal layer in outer tube or water tank external protection are positioned; And boring material hole and relief opening, outer tube or water tank external protection effect one are that the protection polyurethane insulation coating exempts from the hard thing destruction of machinery, the 2nd, anticorrosion waterproof.
Above insulating structure is applied to the use side heat exchanger of ground source hot pump cold-warm air-conditioning or water heating system and connecting pipeline and the hot water storage tank between the connecting pipeline between air conditioner user end or the hot water storage tank and hot water storage tank and the domestic hot-water's user side.
The utility model has the advantages that: utilized the high-quality thermal insulation property of polyurethane, it is extremely low that cold and hot loss is reduced to, and has the characteristics of maximum using renewable energy sources.That outer field protective layer has reached is anticorrosion, waterproof, effect such as tamper-proof.In a word, polyurethane thermal insulation system not only has advanced technology, the practicability that traditional heat-insulation system hardly matches, but also has remarkable social benefit and economic benefit, also is the effective measure of heating and refrigerating energy saving of system.
