METHOD FOR CONTROLLING FAN OF FREEZING CHAMBER

摘要

PURPOSE: A control method of a fan of a freezing chamber is provided to perform efficient cooling by driving a fan of a freezing chamber at the point of which the temperature of a freezing chamber is over defrosting temperature after driving a compressor. CONSTITUTION: A first temperature detection unit(10) installed in a certain position in a freezing chamber detects the indoor temperature of a freezing chamber by an F sensor and feeds the detected temperature to an A/D(analog to digital) port of a microcomputer(30) detecting a temperature detecting signal of the freezing chamber. A second temperature detection unit(20) feeds the defrosting temperature detected by a D sensor(30) to the A/D. The microcomputer drives an F fan(50) if the temperature of the freezing chamber is over defrosting temperature. A fan driving unit(40) outputs a certain driving signal to the F fan according to the control by the microcomputer using a driving element or a relay. The F fan vents cool air around an evaporator to the freezing chamber and a refrigerating chamber.
