Thermotechnical testbed for detecting heat preservation and sunshading performance of external door-and-window system

Abstract

The invention discloses a thermotechnical testbed for detecting heat preservation and sunshading performance of an external door-and-window system. The thermotechnical testbed for detecting the heat preservation and sunshading performance of the external door-and-window system comprises a first box body simulating outdoor environment of summer, a second box body simulating outdoor environment of winter, a third box body simulating indoor environment and a fourth body used for protection. The first box body is connected with the third box body, the first box body and the third box body are provided with a first shared vertical face, a first test hole is formed in the first shared vertical face, and the first test hole is provided with a first test piece frame on one side of the first box body. The thermotechnical testbed for detecting the heat preservation and sunshading performance of the external door-and-window system has the advantages that the box bodies which simultaneously simulate the outdoor environment of summer and the outdoor environment of winter are arranged, and the detection of the shading coefficient, the solar heat gain coefficient, the heat transfer coefficient and other multiple thermotechnical properties of the door-and-window sunshading system can be met.

Description

technical field [0001] The invention relates to a thermal test bench for testing the thermal insulation and sun-shading performance of a door and window system outside a building, in particular to a thermal test bench that can simultaneously detect heat transfer coefficient and sun-shading coefficient. Background technique [0002] The thermal insulation and shading performance of external doors, windows and shading systems of buildings is an important index to evaluate whether a building is energy-efficient or not. The thermal insulation performance testing technology of external doors and windows is relatively mature, that is, the calibration hot box method is used to simulate indoor and outdoor environmental conditions, and the test piece is placed on the hole between the cold and hot boxes to measure the heat transfer between the two boxes. To judge the insulation performance of the test piece. [0003] For the shading performance of the door and window shading system, ...
