Method for operating a cooler

摘要

The method involves determining thermal performance of refrigerating machine (1) and required speed of compressor (3). An allowable rotational speed range of the compressor is determined for each operating point of refrigeration machine. A speed of the compressor is regulated to lower and upper speed limit, when required speed of compressor is below or above the permissible speed range respectively. An independent claim is included for a refrigerating machine.
