ABSTRACT
In this chapter, design rules are developed which, within a given set of components, allow the finding of all competing cycles. Multistage vapor-compression systems are used predominantly for refrigeration purposes when high temperature lifts are required. To facilitate the search for new cycles, a more systematic approach is introduced. The main components of absorption machines and heat engine cycles can, in principle be connected arbitrarily by tubing for working fluid or for solution in the same way that electronic components can be connected to circuits and networks. Cascades can be created by combining single as well as multistage configurations. For the chapter, the convention is used that the compression/expansion machine is always located towards the right of the exchange unit supplying or receiving the vapor. The vapor generated in the generator acts as a heat transfer medium and flows directly to the absorber to produce heat.
