Refrigerator or freezer device for domestic use

摘要

The refrigerator or freezer (2) has an evaporator (6) in the storage compartment (4) chilled by a compressor (8). An air temperature sensor (14) in the storage compartment is connected to a microprocessor unit (16) for temperature control, which controls the running of the compressor. The microprocessor memory (18) stores reference and maximum temperatures of the sensor and the relative running and stationary periods of the compressor and operates a defrost cycle within safe limits.
