Title:
CONTROLLER FOR FREEZING REFRIGERATOR
Document Type and Number:
Japanese Patent JPH06307753
Kind Code:
A
Abstract:
PURPOSE: To maintain capacity of a cooling system for a long period by reducing an operation of a compressor when an operating load the compressor is increased irrespective of a decrease in cooling capacity in a freezing refrigerator for cooling and storing food.
CONSTITUTION: When an operating efficiency of a compressor 17 calculated by operating efficiency calculating means 23 is raised or a change rate calculated by change rate calculating means 25 is lowered, reference temperature correcting means A25, B28 raise a reference temperature for operating the compressor 17 thereby to reduce the efficiency of the compressor 17 to alleviate an operating load of a cooling system.
