Abstract

Several different system balance methods and programmes have been developed and used for decades in the refrigeration industry to design refrigeration circuits and components. One of the oldest methods is the graphical—analytical method, developed and used long before computers and even calculators became standard engineering tools. The method is relatively easy and it helps to design and choose proper components. It can be successfully used today in the computer age for a better understanding of the refrigeration system behaviour, enabling the designer to see and evaluate major components, system characteristics, and system trends.

This article will introduce the graphical—analytical method for the simplest refrigeration systems and later extend it to more complex refrigeration systems.
