引言蒸汽两效溴化锂吸收式制冷机,是溴化锂吸收式制冷机中一个重要的机型,在国外的应用已越来越广泛,国内也正在推广使用。型式与结构,是为其热力循环服务的,最终以其热力指标来评价与衡量一种型式或结构的优劣。其次,还要考虑到加工条件、起重运输以及一些特殊的使用场合。型式与结构的确定,主要要考虑制冷循环中各热力过程的完善度。借助于样机的试验、传质、传热的试验,并考虑与之有关的众多因素,综合论证,予以确定。蒸汽两效机型的型式与结构,是基于单效机型的基础之上。单效机型的型式与结构已有 Introduction Steam two-effect lithium bromide absorption chiller is an important type of lithium bromide absorption chiller. It has been applied more and more widely in foreign countries and is being promoted domestically. Type and structure, for its thermal cycle services, and ultimately its thermal indicators to evaluate and measure the advantages and disadvantages of a type or structure. Second, we must also consider the processing conditions, lifting and transport and some special occasions. Determination of the type and structure, mainly to consider the refrigeration cycle of the thermal process of improvement. With the prototype test, mass transfer, heat transfer test, and consider the many factors related to the comprehensive argument to be determined. The type and structure of the steam two-effect model is based on the single-effect model. Single-effect models of the type and structure of existing
