DEVICE FOR DECREASING NOISE OF DIFFUSION REFRIGERATOR

摘要

PURPOSE: A noise reduction apparatus for a diffusion refrigerator is provided to remove mechanical noise by controlling power supplied to an electric heater depending on the internal temperature of a storage room. CONSTITUTION: A noise reduction apparatus for a diffusion refrigerator comprises a temperature comparing and detecting unit(30) and an output voltage control unit(40). The temperature comparing and detecting unit senses the internal temperature of a storage room and compares the sensed temperature with set temperature. The output voltage control unit controls output voltage required for operating an electric heater depending on the signal outputted from the temperature comparing and detecting unit.
