Building curtain wall door and window thermal insulation and solar heat gain coefficient detection equipment

Abstract

The invention relates to building curtain wall door and window thermal insulation and solar heat gain coefficient detection equipment. The detection equipment comprises a first box body and a second box body which are in sealed butt joint with each other; a curtain wall test piece is installed between the first box body and the second box body, and can be flexibly disassembled and assembled; and afirst flow guide screen and a second flow guide screen are installed in the first box body and the second box body respectively, so that annular air flow is formed inside the first box body and the second box body separately. The second flow guide screen further comprises an orifice plate, wherein the orifice plate is arranged between the top end of the second flow guide screen and the top end ofthe curtain wall test piece; the orifice plate is perpendicular to the second flow guide screen, and through holes are uniformly formed in the surface of the orifice plate; and the orifice plate is used for averaging and adjusting airflow to pass through the surface of the curtain wall test piece. An artificial light source is arranged on one side, facing the curtain wall test piece, of the second flow guide screen, wherein the artificial light source is provided with a square lampshade, so that the artificial light source irradiates a region edge of the surface of the curtain wall test pieceto form a regular shape.

Description

technical field [0001] The invention belongs to the technical field of detection equipment for building curtain walls, in particular to detection equipment for thermal insulation of doors and windows of building curtain walls and solar heat gain coefficient. Background technique [0002] In recent years, the country has paid more and more attention to building energy conservation. The building envelope, especially the building curtain wall, has excellent thermal insulation and heat insulation performance, which is a prerequisite for realizing building energy conservation. An important parameter of building energy consumption. At present, the equipment for testing the solar heat gain coefficient or thermal insulation performance in my country basically uses natural light sources, which has certain restrictions on the experimental process and brings great obstacles to the testing practice. The use of artificial light sources for testing is still in its infancy. At this stage, ...

Problems solved by technology

[0005] The current curtain wall detection equipment has a complex structure and a single detection function, which makes it impossible to make full use of the detection equipment box in a large occupied space, resulting in waste

In addition, for large-scale curtain wall specimens, whether it is thermal insulation performance testing or solar heat gain testing, there are high requirements for the uniformity of heating on the tested surface of the curtain wall, which directly affects the accuracy of testing. problems faced by personnel
