Energy conservation in A/C and refrigeration plants by application of electronically controlled pumps

摘要

The application of controlled pumps in the A/C and refrigeration technology is still at the beginning. Preferred for the application first the chilled water circuit can be regarded, but in the back cooling circuit substantial technical pre-working has to be carried out. The controlled pumps used today in the field do not show function problems in principle. In the lab test energy savings up to 70 % are proven. In the field test the experimental proof will be carried out until the end of next year.
