随着能源价格的变化以及制冷技术水平的提高,需要重新考虑燃气驱动的直燃型溴化锂机组的应用可行性。本文通过不同类型冷热源机组一次能源利用率比较,某酒店直燃型溴化锂机组改造方案的比选以及某厂区直燃型溴化锂机组的能效检测,对该种机组与电制冷机组进行了对比分析,得出结论:从经济性和节能性角度出发,上海地区当前宜将电制冷方式作为首选,老旧直燃型溴化锂机组可改造为电制冷机组。
With the changes in energy prices and the improvement of refrigeration technology, the feasibility of gas-driven direct-fired lithium bromide units needs to be reconsidered. In this paper, through comparing the primary energy utilization rate of different types of cold and heat source units, the comparison and selection of the conversion schemes of direct-fired lithium bromide units in a hotel, and the energy efficiency testing of a direct-fired lithium bromide unit in a certain plant, the comparative analysis of such units and electric refrigeration units , Come to the conclusion: from the economic and energy-saving point of view, Shanghai should be the current preferred electric cooling mode as the first choice, the old direct-fired lithium bromide units can be transformed into electrical refrigeration units.
