DEVICE AND METHOD FOR DYNAMICALLY TESTING THERMAL PERFORMANCE OF BUILDING WALL

摘要

A device and a method for dynamically testing thermal performance of a building wall. The device comprises a test box (1); a wall (2) to be tested is provided within the test box (1), and the wall (2) to be tested divides an inner cavity of the test box (1) into a hot chamber (3) and a cold chamber (4); a fixed device (5) is provided at two side edges of the wall (2) to be tested; a protection box (6) is provided outside the test box (1); and a temperature adjustment device (7) and a temperature measurement device are provided between the hot chamber (3), the cold chamber (4), the protection box (6) and the test box (1). The device has a simple and reasonable structure, can achieve the testing of the dynamic heat transfer process of the wall under different weather conditions and air conditioner operation modes, and can achieve the analysis and evaluation of the thermal performance of the wall under different thermal environment conditions.
