在大、中型中央空调工程中，制冷机组的能耗一直是人们关心的问题．不少媒介宣称吸收式冷水机组比蒸气压缩式冷水机组节能，是中央空调发展的方向．本文通过对各种制冷机组的矿物能源能效比进行比较，并进行计算列表分析，结果表明溴化锂吸收式冷水机组比蒸气压缩式冷水机组节电不节能．图３，表１，参６． In large and medium-sized central air conditioning project, the energy consumption of refrigeration units has always been a concern. Many media claim absorption chillers than vapor compression chillers energy saving is the direction of the development of central air conditioning. In this paper, the comparison of mineral energy energy efficiency of various refrigeration units and the calculation list analysis show that the lithium bromide absorption chillers are less energy-efficient than the vapor compression chillers.
