DISPOSITIVO ELETTRONICO DI COMANDO TERMOSTATICO PER CONGELATORE-CONSERVATORE

摘要

The electronic control system used for freezing food preserving units automatically connects and disconnects the refrigerator system. Rapid freezing and preserving is carried out automatically without manual intervention. A temperature sensor (1) held in a freezer cell is connected via signal amplifier (2) to thermostat circuit (4) for refrigerator (6) controlling and to a temp. alarm indicator circuit (3). The latter actuates a logic circuit monitoring calibration of the thermostat circuit. This calibration is modified if cell temp. rises.
