Title: Defrosting system for refrigerator evaporator with heater - compares reference temp. curves with evaporator temp. variation for heater switching
Inventor: BUERGEL JOACHIM
IPC: F25D21/00
Filed: 1976-07-01
Abstract: The evaporator of a refrigerator and deep freeze arrangement uses a heating system for defrosting. The heating performance is controlled during the stationary period of the refrigeration unit in relation to the environment temp. The analogue control circuit of the system can be readily converted into digital form. The temp. of the evaporator is sensed and digitised by an analogue to digital converter. The digital temp. curve, used as a reference curve is stored and compared by a comparator with the temp. variation curve of the evaporator. A timing generator is used for the synchronisation of this comparison process. This generator starts only when the compressor is stationary. The digital outlet signal of the comparator is used for switching the heating resistor on the evaporator on or off.
