Description

Technical Field

[0001] This utility model relates to the field of experimental chamber technology, specifically a photovoltaic curtain wall performance testing experimental chamber. Background Technology

[0002] A photovoltaic (PV) curtain wall is a structure attached to glass and embedded between two panes of glass, using solar cells to convert sunlight into electrical energy. It uses photovoltaic cells and panels to convert sunlight into electricity. The key technology is the solar photovoltaic cell technology. After the PV curtain wall panels are manufactured, a testing chamber is used to perform performance tests on the panels.

[0003] Existing test chambers typically simulate the impact of windy weather on photovoltaic curtain wall panels when conducting performance tests. However, these chambers cannot simulate the impact of wind and rain on photovoltaic curtain wall panels, resulting in a reduced testing range and failing to meet the testing requirements for photovoltaic curtain wall panels under windy and rainy conditions.

[0004] According to announcement number CN203786062U, a photovoltaic curtain wall performance testing experimental box includes a steel plate platform and an experimental box body fixed on the steel plate platform. The box body is characterized by having two independent experimental rooms, A and B, separated by a corridor. An external door connecting to the outside is located on the left side of the experimental box body, and internal doors are located on the inner walls of experimental rooms A and B. A double-layered window connecting experimental rooms A and B to the outside is located on the front of the experimental box body, with detachable ventilation openings at the upper and lower ends of the double-layered window. The technical effect of this invention is that the entire experimental box can simulate the combined effects of solar radiation, outdoor temperature and humidity changes, and wind speed and direction on a building curtain wall. It provides a full-scale testing device for testing the dynamic thermal and electrical performance of building photovoltaic curtain wall components, providing accurate experimental data support for theoretical calculations or research.

Therefore, we need to propose a photovoltaic curtain wall performance testing experimental chamber. Utility Model Content
