摘要 介绍了毛细管辐射空调的特点,以苏州地区某浅埋型地源热泵与毛细管末端组合空调工程为例,从空调末端能耗、末端效率和系统热经济学指标三个方面对毛细管空调进行了全面经济性分析,并与传统风机盘管末端的地源热泵系统进行对比。结果表明,毛细管空调房间温度波动小,能耗低,末端效率比风机盘管系统高38%,单位冷热成本低,虽然初投资较高,但是全系统多出的投资可在4.8 a通过节约的运行费用回收,经济效益明显。 The paper presents the characteristics of capillary radiation air conditioning.By taking a practical pro鄄ject of the shallow buried ground source heat pump system with capillary radiation air conditioning terminal de鄄vices in Suzhou as an example,the comprehensive analysis of economy was made from the three aspects of ener鄄gy consumption,energy efficiency of air-conditioning terminal and the thermal economics index of system,and the traditional GSHP system with fan coil unit was compared in details.The results show that the temperature fluctuation of capillary air-conditioning room is small,the energy consumption is low;the energy efficiency of air-conditioning terminal is 38%higher than the fan coil system,and the cost of cold(hot)energy is also lower.Although the initial investment of capillary air-conditioning system is high,the excess investment can be recov鄄ered through the operation cost saving in 4.8 years.In conclusion,the capillary air-conditioning system can achieve the most economic benefits.
