TEMPERATURE CONTROL DEVICE FOR REFRIGERATOR

摘要

PURPOSE: A temperature control device for a refrigerator is provided to improve the temperature control efficiency of a refrigerator by minimizing the change of the temperature inside a refrigerator and by quickly coping with the change of a load. CONSTITUTION: The temperature control device has:a temperature detecting sensor(10) to detect the temperature inside a refrigerator; a fan motor(50) to drive a fan of the refrigerator; a micomputer(20) to output a control signal by calculating the speed of the fan motor(50); a calculating unit(30) to calculate the change rate of the temperature detected from the temperature detecting sensor(10); a fan motor driving unit(40) to output a certain driving signal to the fan motor(50) by using a driving element and the relay according to the control signal of the micomputer(20).
