Vapor Compression-Cycle Systems

I he basic vapor compression refrigeration cycle JL consists of the four processes discussed in Chapter 33 — expansion, evaporation, compression, and condensing. The ideal vapor compression refrigeration cycle is the reverse Rankine cycle (see Chapter 11). Whereas, in the Rankine cycle, vapor expansion produces work output, in the reverse Rankine cycle, vapor compression work produces refrigeration effect. This vapor compression work is done by refrigerant compressors that are driven by electric motors and fuel- or steam-powered prime movers.

This chapter describes the vapor compression cycle and types of equipment commonly used for its application, as well as applicable compressor types, refrigerants, system performance, and capacity control. It also includes a detailed discussion on vapor compressor drivers.
