溴化锂吸收式冷水机在客船上的运用

Application of LiBr Absorption Chiller on Passenger Ship

在"双碳"的目标背景下,客船设计越来越注重节能性。客船上的空调系统是保障船员和旅客舒适度的重要系统,现在船舶上大都使用压缩机驱动氟利昂来制冷,需要消耗大量的电能,而溴化锂吸收式冷水机是利用船舶上主机产生的废热来驱动制冷循环,可大大节省电能消耗。同时,溴化锂吸收式冷水机以水为制冷剂,溴化锂溶液为吸收剂,ODP和GWP均为0,对生态环境无破坏作用。文章首先介绍了溴化锂吸收式冷水机的特点,然后结合实际项目研究了吸收式冷水机在船舶上如何运用,包括空调水系统的设计和吸收式冷水机在的辅助系统的设计,最后通过与电制冷水机对比说明吸收式冷水机的节能特点。研究表明,客船上具备运用溴化锂吸收式冷水机的优良条件,相对于传统的冷水机,溴化锂吸收式机组的节能效果可以达到70%以上,具有很大的应用前景。

Under the background of"double carbon",passenger ship design pays more and more attention to energy saving.HVAC is an important system to ensure the comfort of crew and passengers.At present,refrigerant driven by compressor is mostly used on ships,which consumes a lot of electric energy.The Li Br absorption chiller uses the waste heat generated by the main engine of the ship to drive the refrigeration cycle,which can greatly save the consumption of electric energy.At the same time,LiBr absorption chiller uses water as the refrigerant,Li Br solution as the absorbent,and ODP and GWP are both 0,which has no damage to ecological environment.Firstly,the characteristics of LiBr absorption chiller are introduced,then how to use the absorption chiller on ships is introduced,including the design of air conditioning water system and the design of auxiliary system of absorption chiller.Finally,the energy saving characteristics of absorption chiller are illustrated by comparing with electric chiller.Through the research of this paper,the passenger ship has the excellent conditions to use LiBr absorption chiller.Results show that compared with the traditional chiller,the energy saving effect of LiBr absorption chiller can reach more than 70%,which has a great application prospect.
