首先介绍毛细管辐射采暖地面和顶棚构造,并采用试验方法分析热泵机组供热性能,然后采用BIN法计算不同热源方案毛细管采暖系统能耗,分析其节能性;最后分析各热源方案的初投资和运行费用以及其对环境影响.通过研究得出:(1)地源热泵机组提供28～35℃的低温热水时的COP值与制取40～50℃热水相比大大提高,节能效果显著;(2)在冬季采暖总耗煤量方面,地源热泵系统最小,与风冷热泵、天然气燃气炉相比分别节省了32.9%、129%的耗煤量;(3)采用天燃气采暖炉为热源时,污染物排放量最少,对环境破坏最小;(4)从经济方面分析,风冷热泵冷热水机组是最优的热源方案.

The article presented particularly the arrangement form and structure of ceiling and floor of capillary tube mat. The experimental method was employed to study heating performance of heat hump unit. And then, BIN method was adopted to calculate heating energy consumption of radiant heating system of capillary tube with different heat source schemes and analyse its energy efficiency. At same the time, its investment, operating cost, and environmental impact was analysed. Through the analysis, some conclusions could be drawn as follows:(1)coefficient of performance COP of heat pump unit in heating mode was greatly improved when the average supply water temperature was 28~35℃ compared with 40~50℃. So the effect of energy conservation was apparent.(2)when the ground source heat pump compared with air cooled heat pump and the gas furnace with natural gas, its heating coal consumption had saved more 32.9%, 129% respectively.(3)discharging pollutant of gas furnace with natural gas were less than that of other schemes , so it was most environmental friendly in all schemes.(4) on the economy, air cooled heat pump was the best heat source scheme in all schemes.
