Claims

[Scope of Claim for Utility Model Registration] (1) In an anti-freezing device used for equipment in which low-temperature air from outdoors and high-temperature air from indoors flow respectively, the low-temperature air to be supplied to the equipment is supplied from the outdoors. A box body is provided in which a low-temperature flow path is introduced, and a high-temperature flow path is partitioned from the low-temperature flow path by a partition wall and discharges indoor high-temperature air from the equipment to the outdoors. is provided with an opening that communicates the low-temperature flow path and the high-temperature flow path, and the box body is provided with an inlet of the low-temperature flow path and an outlet of the high-temperature flow path, with the opening normally closed and opened when necessary. and a control device that generates heat by energizing a heating element provided between the opening of the partition wall and the outlet of the low temperature flow path when the damper opens the opening of the partition wall. Prevention device. (2) A request for registration of a utility model characterized in that the control device detects the temperature of low-temperature air flowing through a low-temperature flow path, and intermittently energizes a heating element when a predetermined temperature or lower is detected. The antifreeze device according to item 1.
