摘　　要：搭建了室外太阳辐射得热量的测量装置,通过测量电加热量、风机功率,计算风机盘管换热量、围护结构传热量得到室内太阳辐射得热量。测试结果表明:室内太阳辐射得热量和实际情况一致,并且当太阳辐射强度有波动时,装置也能很好的跟踪测量透过玻璃的室内太阳辐射得热量。依据太阳辐射理论及当地地理气象条件进行数值模拟,将测试值与模拟值进行比较,两者吻合度很好。The solar heat gain has a great influence on the energy consumption of the buildings. Especially in summer, the solar heat gain through the glass windows takes a big part in the cooling load. An outdoor test facility which is used to measure the solar heat gain through glass windows is presented in this paper. The solar heat gain is gotten by measuring electric heater power and fan power, calculating the heat exchange of fan-coil unit and the heat flux through the envelopes. The experimental data show that the measured solar heat gain through glass windows coincides with that of the practical situation, and the solar heat gain can also be measured accurately using the test facility even when the exterior solar radiation fluctuates. In addition, based on the solar radiation theory and local weather conditions, the exterior solar radiation and solar heat gain are numerically simulated by the computer. The experimental results have relative good agreement with the simulation results.
