210kW 溴化锂吸收式制冷系统设计摘 要随着国家经济的不断发展，工业生产和生活消费带来的环境污染越来越严重，人们也逐渐意识到环境破坏带来的影响是十分恶劣的，要保护环境的意识也逐渐增强，大家都在寻找可以替代以往对环境不利的物质材料的新型材料和方法。例如人们在制冷方面积极的寻求取代 CFC 制冷剂的对策，而在替代使用 CFC 制冷剂的电动式制冷机组方案中，溴化锂吸收式制冷机组并不需要 CFC 制冷剂，以其可利用各种余热废热、耗电少、运行时无噪音、维护操作方便、对大气臭氧层无破坏等的优势，逐渐成为制冷方面的主流发展方向，减少甚至替代 CFC 制冷机组的生产利用。由此看，研究溴化锂吸收式制冷系统具有重大意义，且溴化锂吸收式制冷有广阔的发展前景。本文主要根据课内所学内容和课程设计操作为基础，以溴化锂吸收式制冷系统的工作原理和特点为依据，设计制冷量为 210kW 的溴化锂吸收式制冷系统，主要设计步骤有热力计算、各个设备的热负荷计算和设计、传热计算等，最后根据溴化锂吸收式制冷的优缺点进行分析，得出其具体的节能措施和主要用途。关键词：溴化锂；吸收式；制冷；设计Design of 210kW lithium bromide absorption refrigeration systemAbstractThe awareness of protecting the environment has gradually increased, people are looking for new materials and methods that can replace the materials that have been harmful to the environment. For example, people actively seek to replace CFC refrigerants in the refrigeration field, and in the alternatives to CFC electric chillers, lithium bromide absorption chillers do not need CFC refrigerants, with its advantages of utilizing various waste heat, low power consumption, no noise during operation, convenient maintenance and operation, and no damage to the ozone layer in the atmosphere, it has gradually become the mainstream development direction in refrigeration, reduce or even replace the production and utilization of CFC refrigeration units. Therefore, the research on LiBr absorption refrigeration system is of great significance, and LiBr absorp...
