摘　　要：本文论述了我国地热资源的分布，并建立了以地热水为补偿的溴化锂吸收式制冷的数学模型，给出了放气范围Δｘ＝４％时的蒸发温度ｔ０、冷凝温度ｔｃ和热水温度ｔｈ之间的关系式，还给出了制冷循环的热力系数ξ和稀溶液的循环倍率ｒ随热水温度的变化曲线．In this paper the distribution of geothermal in China is presented, in LiBr-H 2O absorptive refrigeration system by geothermal, a mathematical model of refrigeration is set up. The relation of hot water temperature (t h ) with evaporator temperature (t 0) and condenser temperature (t c ) is given, where the concentration difference of LiBr-H 2O solution is 4%. The curves of ξ (coefficient of performance) to t h r(circulation ration) to t h , on various conditions are also constructed.
