Design, Selection and Operation of Refrigerator and Heat Pump Compressors - IMechE Seminar
Wiley, Mar 6, 1998 - Technology & Engineering - 101 pages
There have been several recent developments that have affected the design and operation of refrigerator compressors. The most significant changes have been brought about through legislation concerning the use of CFCs and those relating to the close control of chilled food storage cabinets.
Topics covered in the Design, Selection, and Operation of Refrigerator and Heat Pump Compressors include: compressors and energy efficiency, influence of capacity control on the working process of a refrigeration screw compressor, increasing the efficiency of the compression process, influence of refrigerant properties on standard compressor rating figures, and simulation and control of multi-compressor refrigeration systems.
Highlighting recent advances in compressor technology, with particular emphasis on energy efficiency in selection and operation, this volume will be of great interest and value to all those concerned in this area of the power industries.
