【英文篇名】 Energy consumption analysis of air conditioning refrigeration and cogeneration systems 【作者中文名】 严德隆; 张维君; 【作者英文名】 By Yan Delong and Zhang Weijun; 【作者单位】 中国电子工程设计院; 【文献出处】 暖通空调, Hv 压缩式制冷; 溴化锂吸收式制冷; 热电冷三联产; 等效燃料利用系数对比; 【英文关键词】 energy efficiency; compression refrigeration; lithium bromide absorption refrigeration; cogeneration; equivalent fuel consumption factor; comparison; 【摘要】 针对溴化锂制冷尤其是在热电冷三联产时是否比压缩式制冷节能的争论，提出了以煤为对象的等效燃料利用系数Ｋｓ的概念和计算公式，用以对比分析了三者的Ｋｓ值，得出在目前发电效率水平下热电冷三联产在采用高压机组时一般才是节能的，在其他情况下是否节能是有条件的。 【英文摘要】 In view of the debate over whether the lithium bromide absorption refrigeration, especially in cogeneration combining heating, cooling and power supply, is more energy efficient than compression refrigeration, provides the equivalent fuel consumption factor K s and its calculation formula, by means of which compares the K s values for the three system and concludes that the cogeneration system can be energy efficient only when the high pressure generator unit is involved, otherwise the energy effi...
