Abstract : Performance of direct-fired lithium-bromide (LiBr) absorption chiller and air-cooled heat pump
were briefly introduced. Hourly heating/cooling demand of several typical buildings in Shanghai were calculated. Annual gas consumption for LiBr absorber and electricity-driven heat pump were determined based upon hourly demand and corresponding performance data, respectively The economic benefits of direct-fired LiBr absorption chiller versus air-cooled heat pump was analyzed for existing gas and electricity prices. The seasonal pricing for direct-fired LiBr absorber applications was proposed

1前言
随着对生活和居住环境要求的不断提高，中央空调的使用日益增多，导致城市电网尖峰负荷问题凸出。同时，天然气出现了供需不平衡间题。直燃型溴

化锂机组（下简称漠冷机）是利用天然气为热源，以水和溴化锂为工质（高沸点的溴化锂为吸收剂、低沸点的水为制冷剂），整个制冷循环主要由蒸发器、吸收器、发生器、冷凝器、溶液泵等组成，其工作原理如图1所示()。
