According to GB/T 8484-2020 "Test Method for Thermal Insulation Perbance of Building External Doors and Windows", the theoretical basis of this b is the calibration hot box b in GB/T 13475-2008 "Determination of Thermal Insulation Steady State Heat Transfer Properties - Calibration and Protection Hot Box Method". It is based on the principle of steady-state heat transfer and uses the calibrated hot box b to detect the heat transfer coefficient of building exterior doors and bs. One side of the test piece is a hot box, simulating the indoor temperature conditions of a heating building in winter; The other side is a cold box that simulates outdoor temperature and airflow velocity in winter. After sealing the gaps of the specimen and maintaining stable air temperature, airflow velocity, and thermal radiation conditions on both sides of the specimen, measure the heat generation per unit time of the heating device in the hot box. Subtract the heat loss passing through the hot box wall, specimen frame, filling plate, specimen, and filling plate edge, and divide by the product of the specimen area and the temperature difference between the air on both sides to obtain the K value of the specimen's adhesion coefficient.
