摘要
对新型分布式供能系统(简称新型系统)的特性进行了分析,并将其与土壤源热泵机组和直燃式溴化锂冷热水机组进行比较,得出新型系统设计工况和变工况性能均较好,其中负荷在0.5～1之间时效率较高。通过对北京地区某建筑物冬夏季的能耗分析,得到新型系统分别比土壤源热泵机组和直燃式溴化锂冷热水机组节能23.1%和37.1%,其节能性相当可观,是一个值得推广的系统。
The characteristic analysis of new distributed energy resources（NDER） was done. The NDER has a better ondesign and off-design performance compared to the performances of ground source heat pump and direct-fired lithium bromide water chiller/heater, especially in 50%-100% load. Through the energy consumption analysis of some building alloperation heating and cooling demands in Beijing, the energy saving ratios of NDER are 23.1% and 37.1% compared to ground source heat pump and direct-fired lithium bromide water chiller/heater, respectively. Consequently, NDER is a worthy and remarkable energy saving system.
