Background technology

At present, " the low temperature underground heat " of advantages such as the warming installation of cold district is comfortable by having, attractive in appearance gradually, saving space replaces, and the air conditioning type floor with function cool in summer and warm in winter also more and more is subjected to people's popular welcome.In this case, also more and more receive publicity, and the research of air conditioning type floor is to carry out on the basis of transforming underground heat form of structure equally, so the structure of modification of underground heat is particularly important for the research and design of geothermal heating, air conditioning type floor.

In recent years, geothermal heating mainly contains following several form: dish water pipe+cement, dish cable+floor, Electric radiant Heating Film+cement, promotion and application are accepted and obtained to the geothermal heating mode of these several forms by users to a certain extent, but still there is following problems: first, coil water pipe or cable and all a spacer segment need be arranged, about 150-250mm is for face of land heat radiation and evenly necessary certain thickness cement layer, the 50mm at least of covering of temperature.Yet cement layer has approached and has very easily made cement surface cracking, and the cement bed thickness can influence radiating effect, main is to waste energy, and has increased the height of the interior space simultaneously again, the load-bearing in building increases again to some extent; The second, in case find the not hot or leakage in floor, the shaver ground maintenance has not only increased maintenance cost, has also destroyed user's finishing; The 3rd, can only heating can not lower the temperature, function singleness requires the heating water temperature more than 50 ℃, and heating duration is long, otherwise does not come on the surface temperature; The 4th, the construction works amount is big, and it is fully loaded to increase the building body, and also must construct under the environment temperature conditions of higher winter, otherwise causes cement loose easily; The 5th, cause incrustation scale to need periodic cleaning in the dish water pipe, the scale removal process complexity.

In sum, present underground heat form of structure still needs to improve.

Summary of the invention

The objective of the invention is for provide a kind of structure design more rationally, the channelling water heating and cooling underground heat of energy-conserving and environment-protective, fundamentally solve the problem that function singleness, heat utilization ratio are low, construction is subjected to season, weather effect, long construction period, maintenance inconvenience that existing geothermal heating exists, possess advantage cool in summer and warm in winter, as to reduce operating cost simultaneously.

Technical scheme of the present invention is: this channelling water heating, cooling underground heat, comprise and be layed in ground extruded sheet as insulation layer, its technical essential is: described extruded sheet upper surface is offered some matrix grooves that are parallel to each other, all divide into modified PVC water flowing square tube in every described matrix groove, described modified PVC water flowing square tube soffit closely contacts with described matrix groove bottom surface on the described extruded sheet, and every described modified PVC water flowing square tube two ends are carried out thermal capacitance welding back respectively and fed water knockout drum.

Advantage of the present invention and positive technique effect are: owing to adopted modified PVC water flowing square tube as the water flowing passage, modified PVC water flowing rhs-structure is simple, the matrix groove of offering on its soffit and the extruded sheet closely contacts, no matter this underground heat top is provided with the last deck panels of which kind of form, which kind of material, its heat conduction directly effectively, heat insulation effect is fabulous, and the cold water cooling-down effect is effective too.By extruded sheet--the ground heat structure that modified PVC water flowing square tube forms is very simple, and the construction maintenance is all very convenient, need not consider factors such as weather temperature during construction, and construction sequence is few, has saved the most engineering time, has reduced construction costs.In addition, according to interior space size, can independently select every modified PVC water flowing square tube length, its two ends carry out respectively can directly feeding water knockout drum after the thermal capacitance welding, it need not be provided with syndeton, need not consider that the elongated design heat utilization ratio of sealing device is high, circulates in water service pipe with 30-40 Celsius ° water winter to reach as snug as a bug in a rug heating effect.Be equally applicable to cold water, generally use 17-20 ℃ of cold water to get final product when cooling in summer, energy-conservation nature can be realized winter heating, cooling in summer efficiently.To sum up, the present invention has fundamentally solved the problem that function singleness, heat utilization ratio are low, construction is subjected to season, weather effect, long construction period, maintenance inconvenience that existing geothermal heating exists, have energy-conservation, material-saving, utilize the advantage of heat, low-temperature receiver efficiently, doubly than traditional high 2-4 of the wooden floor thermal efficiency.
