Abstract

This paper presents experimental research and analysis of energy efficiency for direct radiant floor heating system with ASHP (air source heat pump). An experimental platform was built, and the performance of ASHP, heating effect and energy consumption of heating system were studied. The results show that the indoor heat load can be well met when the output capacity of ASHP runs at 30%, in which the floor surface temperature and indoor air temperature were reached at 26 °C, 22 °C, respectively. Vertical temperature field can well met the requirements of indoor thermal comfort. Besides, the paper examines heating performance for different envelope, the results indicate that as the condensing coil spacing decreases, the indoor heating effect gets better, but the consumption of energy and tubes increase. Finally, testing the hourly energy efficiency ratio of heating system, and comparing energy efficiency of different technologies, the results point out that radiant floor heating system with ASHP has the best energy efficiency and the obvious advantage of energy saving compared with other heating technologies.

空气源热泵地板直接辐射采暖系统能效的实验研究与分析

本文对空气源热泵地板直接辐射采暖系统的能效进行了实验研究和分析。搭建了实验平台，对空气源热泵的性能、供热效果和供热系统能耗进行了研究。结果表明:当空气源热泵输出容量为30%时，地板表面温度为26℃，室内空气温度为22℃，可以很好地满足室内热负荷。垂直温度场能很好地满足室内热舒适的要求。此外，本文还对不同围护结构的采暖性能进行了测试，结果表明，随着冷凝盘管间距的减小，室内采暖效果越来越好，但能耗和管材消耗增加。最后，对采暖系统的小时能效比进行了测试，并对不同技术的能效比进行了比较，结果表明，与其他采暖技术相比，采用空气源热泵的地板辐射采暖系统的能效比最好，节能优势明显。
