摘　　要：为精确测量各种遮阳窗口系统的太阳得热系数,搭建一套遮阳窗口系统太阳得热系数测定实验平台。该平台主要由太阳辐射模拟器、环境室、热箱、试件、热计量箱、循环水温度控制及计量系统等组成。实验测试基于稳定传热原理测量2个恒温箱之间建筑围护的净热流值,平台对温度、流量、太阳辐射强度等热物理参数实时监控,能实现系统工况参数的自动检测、监控与存储,从而实现智能控制。接着,重点分析实验测试所需的3个标定测试以及测试方法。最后对典型试件进行测试,并与Windows 7.4的计算值进行对比,研究结果表明测试数据与计算数据具有较好的一致性,测试平台的可靠性较高。In order to measure the solar heat gain coefficient of shading window system accurately,a test platform for determination of the solar heat gain coefficient was set up. Firstly,the construction of the platform was introduced,the platform is mainly composed of solar simulator,environment rooms,hot box,specimen,heat metering box,circulating water temperature control and measurement system,etc. The measurement of the net heat flow between two incubator boxes is based on the principle of steady heat transfer. Thermal physical parameters,such as temperature,flow rate,the intensity of solar radiation can be monitored by the platform real-timely,so these parameters can be automatically detected,monitored and stored,so as to realize the intelligent control. Secondly,three vital calibration tests and test method were discussed in detail. Finally,typical specimens were tested,and the test results were compared with the calculated value of Windows 7.4,results show that the test data and calculated data has good consistency,and the test platform has high reliability.
