型式结构溴化锂吸收式制冷机的型式结构要根据机器的容量、使用场合、加工条件和运输方便等方面来综合考虑。使用较为普遍的可分为:单筒、双筒、三筒等型式。还有在特殊场合下采用的多筒及立式结构型式,由于使用较少,本文从略。关于为了充分地利用热能,获得更高的经济效果,而采用两级发生(国外称为二效或二重效)的结构型式,将在以后另作专门介绍。1.单筒型式所谓单筒,就是将发生器、冷凝器、蒸发器和吸收器等四部分都置放在同一筒体之内(见图1所示)。这种型式为壳管式结构,各换
Type structure Lithium bromide absorption chiller type structure according to the capacity of the machine, the use of occasions, processing conditions and ease of transport to consider. The more common use can be divided into: single cylinder, double cylinder, three cylinders and other types. There are special occasions used in the multi-tube and vertical structure type, due to the use of less, this article omitted. For the sake of making full use of heat energy and obtaining higher economic effects, the structure type adopted in two stages (known as second-effect or second-effect in foreign countries) will be specially introduced later. 1. Single-cylinder type The so-called single-cylinder, is to place the generator, condenser, evaporator and absorber four parts are placed in the same cylinder (see Figure 1). This type of shell and tube structure, each change
