| 摘 要： | 采用改进的温频法进行负荷计算,针对夏热冬冷地区某居住建筑的冷热源方案进行全寿命周期经济性分析。结果表明,采用地源热泵方案经济性最好,比空气源热泵节省费用约7.5%,比冷水机组加燃气锅炉方案节省费用约21.2%。同时,输配能耗占总能耗比重约20%,应优化设计输配系统,降低输配能耗。采用地源热泵方案时,如能采用与冷却塔的复合运行模式,其运行能耗将进一步降低。

| Abstract: | Adopts the improved BIN method to calculate cooling and heating load.Makes economic analysis in all life of cold and heat sources for residential buildings in hot summer and cold winter area.The results show that adopting ground source heat pump is the most economic choice.The total cost including initial investment and operating cost is approximately less 7.5% than air source heat pump,less 21.2% than water chiller and gas-fired boiler.As the same time,the energy consumption of transmission and distribution system is approximately 20% of total energy consumption.It demonstrates that the transmission and distribution system needs optimization so as to diminish energy consumption.Applying the combined system with cooling tower in ground source heat pump will decrease the energy consumption further. |
