| 摘 要： | 针对区域供冷系统存在的能耗问题,通过对日本两个典型区域供冷项目具体案例的深入分析,指出其能耗水平,结合国内典型公共建筑分散供冷供暖系统的能耗数据,指出区域供冷高能耗的根源所在.在分析了国外一些成功区域供冷案例的成功之处后,进一步指出区域供冷遇到的各种问题,认为区域供冷系统节能的前提条件是具备高密度的冷负荷用户和足够量的廉价天然冷源.

| Abstract: | In order to clarify energy consumption problems with district cooling systems, sets out energy consumption level by a detailed analysis of two classic district cooling system case studies in Japan. Comparing with the cooling and heating energy consumption data of Chinese typical public buildings, points out the ultimate causes for the high energy consumption of district cooling systems. Based on an analysis of some successful district cooling projects in developed countries, discusses the problems encountered in district cooling systems. Considers that the energy saving preconditions for district cooling systems are sufficient concentration of cooling users and enough low-cost natural cold sources. |
