MCBW-1821门窗保温性能检测设备 建筑门窗保温性能检测设备 建筑门窗保温性能试验机
一、设备简介:建筑门窗保温性能检测设备是我公司最新研制开发的全自动检测系统。依照GB/T 8484-2020《建筑外门窗保温性能检测方法》,该方法的理论依据为GB/T 13475-2008 《绝热 稳态传热性质的测定 标定和防护热箱法》中的标定热箱法。它是基于稳态传热原理,采用标定热箱法检测建筑外门窗传热系数。试件一侧为热箱,模拟供暖建筑冬季室内气温条件;另一侧为冷箱,模拟冬季室外气温和气流速度。在对试件缝隙进行密封处理,试件两侧各自保持稳定的空气温度、气流速度和热辐射条件下,测量热箱中加热装置单位时间内的发热量,减去通过热箱壁、试件框、填充板、试件和填充板边缘的热损失,除以试件面积与两侧空气温差的乘积,即可得到试件的传执系数K值。

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.
