我国空气源热泵地板辐射系统分区研究
Zoning application of air-source heat pump floor radiant heating systems in China
摘要：
近年来，空气源热泵地板辐射供暖技术不断发展，其气候适应性不断扩大，但我国缺乏对不同地区空气源热泵地板辐射供暖的性能评估，限制了其在我国的应用。基于EnergyPlus，采用实际供暖季节性能系数AHSPF和供暖保障率J 2个指标对我国41个城市的空气源热泵地板辐射供暖进行了综合性能评价。空气源热泵地板辐射供暖性能评估通过选址、建筑负荷计算、系统模拟和评估等过程进行。结果表明：空气源热泵地板辐射系统供暖在夏热冬冷地区表现优异，多层居住建筑实际供暖季节性能系数AHSPF在3.03~3.88之间变化，高层居住建筑AHSPF在3.96~4.83之间变化;寒冷地区AHSPF虽然偏低，但能较好地提高室内温度，具有推广意义。用彩色图谱给出了AHSPF和J 2个指标的分布，并通过分析供暖期内COP频次分布，指出了空气源热泵地板辐射供暖系统的不足。
Abstract：
In recent years, air-source heat pump floor radiant heating technology is developing continuously, and its climate adaptability is expanding. However, the lack of performance evaluation of air-source heat pump floor radiant heating in different regions limits its application in China. Evaluates the comprehensive performance of air-source heat pump floor radiant heating systems in 41 cities of China using two indexes of actual heating seasonal performance factor AHSPF and temperature protection rate J based on EnergyPlus. Carries out air-source heat pump floor radiant heating systems performance evaluation through the process of site selection, building load calculation, system simulation and evaluation. The results show that the air-source heat pump floor radiant heating systems perform well in hot summer and cold winter zone, and the AHSPF of multi-storey residential building varies from 3.03 to 3.88, while that of high-rise residential building varies from 3.96 to 4.83. Although the AHSPF is lower in cold zone, it can increase the indoor temperature, which has the significance of popularization. Presents the distribution of AHSPF and J by color map, and points out the shortage of air-source heat pump floor radiant heating system by analysing COP frequency distribution during heating period.
