户式空气源热泵供暖系统不同末端形式分析
Analysis on different terminal forms of household air-source heat pump heating systems
摘要：
选取北京农村地区2016年改造为户式空气源热泵供暖的9户典型案例进行了为期60 d的性能测试。9户典型案例中，末端形式有旧散热器、新散热器、地板辐射盘管。测试期间各案例的室内日平均温度为16.0~22.1 ℃，系统平均COP为2.05~2.79。利用测试数据，对比了采用不同末端形式的典型案例的经济性。结果发现，末端形式为旧散热器、新散热器、地板辐射盘管用户的费用年值分别为24.17，21.11，17.00元/m2。
Abstract：
Conducts a 60-day performance test for nine typical cases of household air-source heat pump heating systems in Beijing rural area which were reformed in 2016. The terminal forms of nine typical cases include the outdated radiator, the new radiator and the floor radiant coil. During the test period, the indoor mean daily temperatures of these cases are between 16.0 ℃ and 22.1 ℃ and the system COPs are between 2.05 and 2.79. Compares the economical efficiency of the typical cases with different terminal forms by test data. The results show that the annual cost of the outdated radiator, the new radiator and the floor radiant coil are 24.17, 21.11, 17.00 yuan/m2, respectively.
