Thermal performance test and analysis of curtain-wall form solar heating system
摘要：
结合幕墙式太阳能供暖系统示范工程，进行了系统热性能测试。在2013年1月7—9日测试期间，室外平均气温为-7.7 ℃，太阳能集热系统的平均集热效率约为27.5%，补热系统的热泵平均COP为1.554；在3月13—15日测试期间，室外平均温度为3 ℃，热泵平均COP为1.782；3月13日的测试结果表明，集热系统的有效平均热效率为18.8%，系统的水箱和管路热损失较小，仅占太阳能有效集热量的9.16%。末端风机盘管采用侧面向下送风的气流组织形式时，室内供暖效果较好。
Abstract：
With a demonstration project, tests the thermal performance of the curtain-wall form solar heating system. In the test period from January 7 to 9 in 2013, mean outdoor temperature is -7.7 ℃, the average collecting efficiency of the solar energy collection system is about 27.5%, and the average COP of heat pump as subsidiary heat source is 1.554. In the test period from March 13 to 15, mean outdoor temperature is 3 ℃, and the average COP of heat pump is 1.782. The test result of March 13th shows that the effective mean thermal efficiency of the solar energy collection system is 18.8%, and the heat loss of water tank and pipeline is comparatively less, which only takes 9.16% of effective heat collection of solar energy. When the terminal fan-coil adopts the air distribution mode of air supply downward from side, indoor heating effect is better.
