Description
Technical field
The utility model relates to a kind of roof, in particular, relates to one and harvests heat and the bifunctional novel energy-conserving roof of reflection.
Background technology
1/3rd of whole society's total energy consumption are accounted at China's building energy consumption, along with the development of economy, improving constantly of living standards of the people, the proportion of building energy consumption will constantly increase, in all kinds of building, the energy consumption of heating ventilation air-conditioning system is maximum, and therefore the emphasis of building energy conservation is the energy-conservation of HVAC.And solar radiation affects Indoor environment a home from home and energy consumption largely.In summer, the heat that sun intense radiation produces causes building roof and exterior wall surface temperature to raise, and heat conducts to indoor by space enclosing structure, can increase the energy consumption of air-conditioning system.For the building of non-air-conditioning, the heat radiation of the rising generation of building internal surface temperature also can worsen the hot comfort of indoor environment.Therefore, adopting effective method to reduce temperature rise caused by solar radiation, reach energy conservation, make the life better, the object of working environment, is an important research topic.
After 20 century 70 oil crisises occur, for reducing the energy consumption of civilian, industrial construction and facility to greatest extent, ETIC (outer thermal insulating compound) outer wall heat preservation system progressively grows up, and China's building energy conservation heat insulation mostly is this system.But because the construction of its system is loaded down with trivial details, cost is high, is not suitable for the construction of abnormal complex structure, and in whole system, there is a large amount of EPS plate seams, define many heat bridges, be difficult to the energy-saving effect of further raising system.And at present conventional external wall outer insulation and interior wall inside holding technology due to the heat capacity of material own limited, roofing is too high easily aging due to temperature, can not give full play to energy-conserving action.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and provide a kind of structure simple, energy-saving effect is obvious, and practical harvests heat and the bifunctional novel energy-conserving roof of reflection.
The purpose of this utility model is achieved through the following technical solutions.
Of the present utility model harvest heat with reflection bifunctional novel energy-conserving roof, comprise the roofing underlay, waterproofing course and the anticracking grout layer that set gradually from the inside to the outside, be provided with the phase-change material layers be made up of the PE-RT pipe close-packed arrays being packaged with phase-change material between described waterproofing course and anticracking grout layer, described anticracking grout layer is provided with reflective coating layer.
Described PE-RT pipe one end is connected with PE-RT pipe cap, and the other end is connected with PE-RT elbow in turn, manages with the PE-RT of steam vent, PE-RT pipe cap.
The Structure composing that described anticracking grout layer is high by centre, periphery is low.
Reflective coating layer thickness is at least 0.5mm.
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
(1) in the utility model, phase-change material layers is made up of the PE-RT pipe uniform close arrangement being packaged with phase-change material, and adopt hot-melt adhesive paste between PE-RT pipe, have connection easy, cost is low, and service life is long, high temperature resistant, the advantages such as good airproof performance.
(2) in the utility model, phase-change material is organic phase change material, phase transition temperature and outdoor roofing temperature close, daytime can effectively store roofing heat, night can effectively outwardly release heat, reduce room conditioning load, material phase transformation latent heat can up to 180KJ/Kg, and less phase-change material can be satisfied the demand.
(3) in the utility model, the sun of reflective coating layer reflects when hemispherical emissivity and is all not less than 0.8, high reverse--bias can be carried out to the solar infrared of 400nm--2500nm scope and ultraviolet, namely before roof absorbs heat, heat reflection is gone out, simultaneously, the hot major part entering reflective coating layer is radiated in air, reflective coating, by reducing roofing temperature, effectively can extend roofing application life.
(4) in the utility model, phase-change material layers is combined with reflective coating layer, can reduce building energy consumption to greatest extent, increases indoor thermal comfort.Roofing cooling capacity limited (situation that outside temperature is higher can not be met) when can make up on the one hand single use reflective coating layer, the shortcoming that fluctuations in indoor temperature is larger; Roofing phase-change material large usage quantity when can make up on the other hand single use phase-change material layers, the shortcoming that roofing is easily aging.
(5) the utility model is passive type energy-saving scheme, and have easy to implement, reliability is high, and life cycle is long, low cost and other advantages.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As depicted in figs. 1 and 2, of the present utility model harvest heat with reflection bifunctional novel energy-conserving roof, comprise the roofing underlay 1, waterproofing course 2 and the anticracking grout layer 4 that set gradually from the inside to the outside, described waterproofing course 2 can be made up of the high polymer waterproof material of 2mm thickness, described anticracking grout layer 4 thickness can be 20mm, can, Structure composing that periphery low high by centre, ensure that rainy day, roofing did not have rainwater to remain; Phase-change material layers 3 is provided with between described waterproofing course 2 and anticracking grout layer 4, described anticracking grout layer 4 is provided with reflective coating layer 5, described reflective coating layer 5 thickness is at least 0.5mm, and the reflective heat-insulation paint that reflective coating layer 5 adopts is made up of high performance resin, high reverse--bias and high radiation particle and filler; Described phase-change material layers 3 is arranged by PE-RT pipe 6 uniform close being packaged with phase-change material and forms, all hot-melt adhesive paste can be adopted between described PE-RT pipe 6, described PE-RT pipe 6 one end is connected with PE-RT pipe cap 8, the PE-RT pipe 9 that the other end is connected with PE-RT elbow 7 in turn, centre position is provided with steam vent, PE-RT pipe cap 8, described steam vent diameter can be 2mm, prevent PE-RT overpressure excessive, described PE-RT pipe 9 length can be 50mm.
Described phase-change material can be organic phase change material, described phase-change material can be organic phase change material, by aliphatic acid, higher alcohols or 46.4 ~ 97.5% aliphatic acid and 2.5 ~ 53.6% higher alcohols eutectic mixture wherein one form, as the eutectic mixture of phase-change material by 71.84% aliphatic acid and 28.16% higher alcohols is made, described aliphatic acid can be n-capric acid, laurate, myristic acid, palmitic acid or stearic acid; Described higher alcohols can be lauryl alcohol, tetradecyl alchohol, hexadecanol or octadecyl alcolol, and phase transition temperature and summer, outdoor roofing temperature was close, setting temperature between 27-30 DEG C, fusion temperature between 32-36 DEG C, latent heat of phase change 140-180KJ/Kg.
Operating principle of the present utility model: daytime, solar radiation acts on reflective coating layer 5, the solar infrared of 400nm--2500nm scope and ultraviolet are carried out high reverse--bias by reflective coating layer 5, the heat weakening the sun carries out accumulation at body surface and heats up, automatically heat radiation radiating and cooling is carried out again, the heat radiation of body surface in space, reduce the temperature of object, the cenosphere that the coefficient of thermal conductivity in reflective heat-insulation paint is extremely low can completely cut off the transmission of heat energy.The heat entered by anticracking grout layer 4 is stored by phase transformation by phase-change material layers 3, and then reduces daytime is entered indoor heat by roof, reduces indoor heat load, increases indoor thermal comfort.
