Overview

Many efforts have been made to reduce the energy consumption of centralized systems by employing advanced refrigeration systems to increase their energy efficiency. Some practical examples include reduced head pressure and mechanical subcooling. This chapter deals with technical and thermodynamic aspects of advanced versions of conventional refrigeration systems, but unconventional systems as well as innovative refrigeration methods and systems. Thermodynamic analyses of advanced refrigeration systems are presented through energy and exergy analyses, and exergetic and exergetic coefficient of performances (COPs). For some industrial applications which require moderately low temperatures (with a large temperature and pressure difference), single vapor‐compression refrigeration cycles become impractical. One of the solutions for such cases is to perform the refrigeration in two or more stages which operate in series. These refrigeration cycles are called cascade refrigeration cycles. The most important advantage of these cascade systems is that refrigerants can be chosen with the appropriate properties, avoiding large dimensions for system components.
