社会的发展,对能源的需求越来越高,节能减排已经成为当今世界的一大趋势.社会需求,民众所需,政策所指,必将促进节能产品的发展.溴化锂吸收式制冷机以热能为动力,电能耗用较少,且对热源要求不高.能利用各种低势热能和废汽、废热、热水以及地热、太阳能等,有利于热源的综合利用.具有很好的节电、节能效果,经济性好.溴化锂吸收式制冷机的特性注定其有着更宽广的发展前景.
此设计机组为600Kw蒸汽型双效溴化锂吸收式冷水机组.以蒸汽为加热源,可利用热电厂废气,商场自备锅炉所产蒸汽等.根据已知工况,冷媒水进水12℃,出水7℃,冷却水进水32℃,加热蒸汽压0.6MPa,确定机组为蒸汽型串联形式,然后对结构进行总体规划和布局,蒸发器、冷凝器、高低压发生器、吸收器均采用壳管式换热；高低温换热器、凝水换热器采用板式换热器.机组设计合理,结构紧凑.

Social development has an increasing demand of energy,energy-saving and emission-reduction have become a huge trend all over the world.Demand of society,people and policy must improve the development of energy-conserving product.lithium bromide absorbed type refrigerating machine uses heat as power,needs less electricity and has a low quality demand of source of heat.it can use a variety of low potential energy and waste gas, waste heat, hot water and geothermal, solar, etc,which is conducive to the comprehensive utilization of heat.
it has a good quality of energy-saving, energy efficiency, economy. The feature of lithium bromide absorbed type refrigerating machine must have a wider development perspectives.
this design of Unit is 600KW steam double effect lithium bromide absorbed type water chillingunit.it use steam as source of heat,and the waste gas from heat plant and shopping owned boiler can be used.According to the known conditions,water coolant is 12℃ in and 7℃ out.cooling water is 32℃ in.Heat pressure of steam is 0.6MPa,fixed unit is steam taye cascade form,then make a overall plan and design towards
constructure.Evaporator,condensator,high-low pressure generator ,absorber use shell and tube to exchange heat . High-low temperature heat exchanger,condenser heat exchanger use plate type of heat exchanger.Unit is designed reasonably,and has a compact constructure.
