太阳能溴化锂吸收制冷系统的优化模拟分析

Solar energy lithium bromide absorption refrigeration system's optimization simulation analysis

基于溴化锂吸收制冷循环的效率受太阳能热源温度较低的影响,文中对太阳能溴化锂吸收制冷系统的循环进行了改进,提出了改进型太阳能溴化锂增压抽气吸收制冷循环,以充分利用太阳能低温热源。新循环不仅克服了传统循环的缺点,降低了驱动热源温度,而且制冷循环相对稳定即使热源温度有波动时,新循环与传统循环的制冷系数也基本相当。

In view of the situation that the efficiency of solar energy lithium bromide absorption refrigeration cycle is limited by the solar energy heat source＇s lower temperature, In this paper, solar energy LiBr absorption refrigeration cycle system has been improved, a modified supercharger exhaust -type solar lithium bromide absorption refrigeration cycle is presented, aiming to take full advantage of its low - temperature heat source. New cycle not only overcomes some shortcomings of the traditional one, lowered the temperature of drive heat source, but even when the heat source temperature is in fluctuation, the COP remained almost the same as the traditional one.
