Abstract

PURPOSE: To directly detect frosted and defrosted conditions as resistance change by using a frost sensor as a frost detector having a negative property of resistance change against relative humidity change.
CONSTITUTION: A defrostor device comprises a frost detector 1 consisting of a frost sensor which detects frost, having a negative property for resistance change against relative humidity change provided on an indoor heat exchanger, a resistance voltage conversion circuit 2, the first comparison circuit 3, the first timer 6, the second compariston circuit 8, the second timer 10, the first AND circuit 11, the second AND circuit 12 and a reset holding circuit 13 which commands to stop defrosting operation receiving a defrost operation stop signal of the second AND circuit 12 and also commands start of defrosting operation receiving a defrost starting signal of the first AND circuit 11.
