Title:
OPERATION CONTROL DEVICE OF REFRIGERATOR
Document Type and Number:
Japanese Patent JP3908801
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform highly efficient operation control by a method wherein the number of revolutions of a compressor is controlled by the temperature of a cooler.
SOLUTION: The temperature of a refrigerating chamber is detected by a refrigerating chamber temperature detecting means 21, a set temperature is detected by a refrigerating chamber temperature setting means and the number of revolutions of a compressor 17 is decided by a number of revolutions computing means 25 according to a temperature difference between a refrigerating chamber temperature and a set temperature. The temperature oft a cooler 13 is detected by a cooler temperature detecting means 42, and when a cooler temperature is reduced to a value lower than a specified value, the number of revolutions is corrected by a number of revolutions correcting means 41, and the number of revolutions of a compressor is controlled by an inverter circuit 26.
