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。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.
