Title:
METHOD FOR CONTROLLING REFRIGERATOR HAVING PELTIER ELEMENT, AND REFRIGERATOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/010112
Kind Code:
A1
Abstract:
A method for controlling a refrigerator including a Peltier element comprises the steps of: measuring the internal temperature of a refrigerator by using a first temperature sensor; determining whether the internal temperature is greater than a first target control temperature; applying a first voltage to a Peltier element if the internal temperature is greater than or equal to the first target control temperature; and applying a second voltage to the Peltier element if the internal temperature is less than the first target control temperature, wherein, in the step of applying a second voltage to a Peltier element, the second voltage applied to the Peltier element is controlled with PID control by using a cooling sink target temperature and a cooling sink temperature measured with a second temperature sensor provided in a cooling sink of the Peltier element.
