EXPERIMENTAL EXPERIENCES WITH EVAPORATOR DEFROSTING OF HEAT PUMPS CORRESPONDING TO DIN 8900.

Author(s) : REICHELT J.

Summary

IN THOSE COUNTRIES WHERE HEAT PUMPS ARE USED BOTH FOR HEATING AND COOLING ONLY REVERSE CYCLE DEFROSTING IS REQUIRED. IN MIDDLE EUROPE COOLING IS NOT NECESSARY, THEREFORE HOT GAS DEFROSTING CAN BE USED INSTEAD OF REVERSE CYCLE. HOWEVER, DEFROSTING TIME OF LARGER HEAT PUMPS (MORE THAN 10-20 KILOW) INCREASES, SO THAT DIN-TEST CANNOT BE APPLIED. A MORE EFFECTIVE DEFROSTING SYSTEM IS SUGGESTED. MEASUREMENTS WITH THIS SYSTEM HAVE BEEN MADE AND THE RESULTS COMPARED WITH OTHER SYSTEMS.
