Variable-speed operation of refrigeration compressors with intelligent frequency inverters - design considerations and experience

摘要

The control of suction pressure by varying the speed o f refrigeration compressors providers many advantages, It the installation is designed correctly then import an considerations such improved quality of stored goods, energy saving, improved performance at light refrigeration loads and increased working life can be easily achieved. This part contribution deals mainly with the wing contribution will deal with important refrigeration aspects of the design of the refrigeration installation.
