Description

technical field [0001] The invention relates to the field of detection of energy-saving performance of a light-transmitting enclosure structure, in particular to a detection device for the solar heat gain coefficient of a light-transmitting enclosure structure and a control method thereof. Background technique [0002] In southern China, building cooling energy consumption is high due to solar radiation in summer, and it continues to increase with climate warming. In hot summer and cold winter areas, power cuts in summer have become the norm, seriously affecting people's lives and social and economic development. Installing shading facilities on the exterior windows of buildings can effectively reduce the energy consumption of air conditioning in summer, especially the movable shading does not increase the energy consumption of heating in winter. At present, more and more construction projects install exterior windows with shading devices or exterior windows with low shading ...

AI Technical Summary

Problems solved by technology

Although the artificial simulated light source detection method can stably and accurately detect the solar heat gain coefficient of the external window, the cost of the artificial simulated light source is very high. The closer the spectrum of the artificial simulated light is to natural light, the more accurate the detected data will be. Coefficient detection requires the use of artificial simulated light sources whose spectrum is close to natural light. At present, the price of artificial simulated light sources with C-level spectrum on the market is about 500,000 yuan, and the prices of artificial simulated light sources with B-level spectrum and A-level spectrum are more than one million. The cost of testing equipment is too high
