Refrigeration Compressors

Order Number: TRG-TRC004-EN
Price: $16

Introduction of the common compressor types used in air-conditioning applications, including reciprocating, scroll, helical-rotary (screw), and centrifugal. (2000)

Topics include:

  • Review of the basic refrigeration cycle
  • Open, semi-hermetic, and hermetic compressors
  • Types of compressors (reciprocating, scroll, helical-rotary, centrifugal)
  • Principles of compressor operation
  • Methods of compressor capacity control (cylinder unloaders, cycling, slide valve, inlet vanes, variable-speed)
  • Methods of system-level control (direct expansion versus chilled water, constant volume versus VAV)
  • Preventing evaporator freeze-up (sensing suction temperature, hot gas bypass)
