Description
Technical field
The present invention relates to construction wall, roof heat insulation technology, particularly a kind of body of wall, roofing installing thermal reflecting coating.
Body of wall is installed insulation layer and becomes energy-saving wall, along with insulation layer thicken, thermal resistance is multiplied.Thermal transmittance is the inverse of thermal resistance, and 200mm concrete wall, 200mm concrete wall install 100mmEPS plate, and during 200mm concrete wall installation 200mmEPS plate, wall heat transfer coefficient is shown in contrast table (containing inner air and outer air layer thermal resistance) below.
Wall heat transfer coefficient value and minimizing absolute value contrast table:
| 200mm concrete wall | The thick EPS plate of 200mm concrete wall+100 | The thick EPS plate of 200mm concrete wall+200 |
| 3.5 | 0.44 | 0.23 |
| Thermal transmittance reduced value | 3.5-0.44＝3.06 | 0.44-0.23＝0.21 |
From contrast table, concrete wall are installed 100mmEPS plate than the 200mm concrete wall not installing EPS plate and reduce thermal transmittance 3.06w/m
2.k, concrete wall are installed 200mmEPS plate than concrete wall being installed 100mmEPS plate and only reduce thermal transmittance 0.21w/m
2.k, not only but also increase the heat-transfer effect much less that stack pile EPS plate reduces.
Also have the warmhouse booth too many problem of heat that to run off winter in severe cold area to be difficult to all the time solve, although the wall thermal insulating in greenhouse, winter fuel consumption still too many, cost is high.Severe cold area fresh vegetables in winter is all transport from south (mainly from Shandong), and increase transport energy consumption, vegetable price is high.
We have known that thermal reflecting coating can reflecting heat, are applied in part life and engineering.Thermal reflecting coating (the 3M film of import and domestic film) is such as installed on vehicle glass; Also as aluminium foil thermal reflectance coating is installed on concrete roof top in south, then keel are installed, keel install roof tile, between roof tile and thermal reflecting coating, has Stilt layer, solar heat can be reduced and penetrate concrete roof and enter indoor; South also installation aluminium foil composite plastic film or the sunshade ceiling blind of aluminium foil cloth glass roof below in summer, not only sunshade, but also to go out the reflect heat of the sun.But also do not install thermal reflecting coating at the body of wall of heating districts, roofing now, for reducing heating districts body of wall, roofing to conduct heat heat waste winter.
Low-energy building is the direction that we develop, and as why not expended a lot of insulation layer, does not increase or reduces and add thickness of wall body, and with comparatively low cost, significantly can also reduce the heat transfer heat waste of body of wall, roofing, be the problem to be solved in the present invention.
For this reason, the present invention proposes a kind of body of wall, the roofing of installing thermal reflecting coating.
Summary of the invention
The object of the invention is to provide a kind of body of wall, the roofing of installing thermal reflecting coating, to solve the problem described in background technology.
A kind of body of wall, roof structure one installing thermal reflecting coating of the present invention, the present invention is inner side thermal reflecting coating being arranged on construction wall, roofing; Described thermal reflecting coating is aluminum foil composite or composite material of aluminizing, and inside the aluminium top foil of thermal reflecting coating or surface layer faced chamber of aluminizing, forms a kind of body of wall, the roofing of installing thermal reflecting coating.
A kind of body of wall, roof structure two installing thermal reflecting coating of the present invention, thermal reflecting coating is arranged on below greenhouse ceiling steelframe by the present invention, or be arranged on below greenhouse ceiling plastic foil, ceiling glass, or the bottom of ceiling cotton-wadded quilt is thermal reflecting coating, described thermal reflecting coating is aluminum foil composite or composite material of aluminizing, inside the aluminium top foil of thermal reflecting coating or surface layer faced chamber of aluminizing, form a kind of body of wall, roofing that thermal reflecting coating is installed.
The key difference technical characteristic of the present invention and public technology is:
