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 characteristics of the new distributed energy supply system (referred to as the new system) are analyzed and compared with the ground-source heat pump units and direct-fired lithium-bromide water chiller units, and the new system design conditions and variable performance conditions Are better, of which the load is higher when the efficiency between 0.5 ~ 1. Through the energy consumption analysis of a building in Beijing in winter and summer, the new system is 23.4% energy saving and 37.1% energy saving than the ground-source heat pump unit and direct-fired lithium-bromide water heater unit, respectively. system.
