基于空气源热泵与新型通水地板的辐射供暖系统应用分析

Application analysis of radiant heating system based on air source heat pump and the new type of water-passing floor

为了研究一种新型通水地板在寒冷地区的实际应用效果,在天津地区某办公楼内搭建了基于空气源热泵与该新型通水地板的辐射供暖系统,并进行了长期的数据监测。研究结果表明,该系统在测试期间季节供热性能系数HSPF为2.19,COP_(sys)平均值为2.20,单位面积供热量平均值为54.6 W/m^(2),有一定的节能效果;在测试最冷日室内温度均在21.0℃以上,具有较好的供暖效果;测试期间典型房间平均温度在23~25℃之间,达到90%以上的满意率,室内人员对室内环境的满意度较高。研究结果为新型通水地板辐射供暖工程的推广应用提供了参考。

In order to study the practical application effect of a new type of water-passing floor in cold area,a radiant heating system based on air source heat pump and the new type of water-passing floor was built in an office building in Tianjin region,and a long-term data monitoring was performed.The results show that the heating seasonal performance factor(HSPF)was 2.19,the average COP_(sys) was 2.20,the average heating amount per unit area was 54.6 W/m^(2) during the test period,which shows a good energy conservation.In the coldest day,the indoor temperature was all above 21.0℃,which still has a good heating effect.The average temperature of a typical room ranged from 23℃to 25℃,reaching the satisfaction rate of over 90%,which shows that the people have high satisfaction with indoor thermal environment.The research results also provide a reference for the popularization and application of the new type water-passing floor heating engineering.
