溴化锂制冷机工作原理、优缺点及保养方法

2017-01-19 

溴化锂制冷机是用溴化锂水溶液为工质,其中水为制冷剂,溴化锂为吸收剂。溴化锂属盐类,为白色结晶,易溶于水和醇,无毒,化学性质稳定,不会变质。溴化锂水溶液中有空气存在时对钢铁有较强的腐蚀性。下面最冷菌就为大家介绍溴化锂制冷机工作原理、优缺点及保养方法,希望对大家有用!


一、溴化锂制冷机工作原理


溴化锂制冷机是利用不同温度下溴化锂水溶液对水蒸汽的吸收与释放来实现制冷的,这种循环要利用外来热源实现制冷,常用热源为蒸汽、热水、燃气、燃油等。由于溴化锂制冷机具有许多独特的优点,近年发展十分迅速,特别是在空调制冷方面占有显著的地位。那么溴化锂制冷机的应用是否有利于提高一次能源的利用率,是否节能,在何种情况下节能,冷热源是否选用吸收式制冷机,一直是人们争论的焦点。溴化锂制冷机在实际中的应用及其使用寿命的长短直接关系到实际工程的经济效益。

二、溴化锂制冷机的优点


1、以热能为动力,勿需耗用大量电能,而且对热能的要求不高。能利用各种低势热能和废气、废热,如高于20kPa(0.2kgf/cm2)(表压)饱和蒸汽,各种排气;高于75℃的热水以及地热、太阳能等,有利于热源的综合利用,因此运转费用低。若利用各种废气、废热来制冷,则几乎不需要花费运转费用,便能获得大量的冷源,具有很好的节电、节能效果,经济性高。

三、溴化锂制冷机的保养方法


为了使溴化锂吸收式制冷机组更好的稳定运行和尽可能的恢复其制冷效果,故日常维护保养十分重要。一般情况下,每台机组在运行3年为了使溴化锂吸收式制冷机组更好的稳定运行和尽可能的恢复其制冷效果,故日常维护保养十分重要。一般情况下,每台机组在运行3年左右,需进行传热管清洗、溴化锂溶液再生等维护保养,否则将会增加耗能降低其制冷量,同时影响机组的使用寿命。需进行传热管清洗、溴化锂溶液再生等维护保养,否则将会增加耗能降低其制冷量,同时影响机组的使用寿命。
