Claims

[Scope of Claim for Utility Model Registration] (1) A box installed outdoors with a low-temperature flow path for introducing outdoor air into equipment that uses outdoor air and indoor air, and the above equipment. A high-temperature flow path for directing indoor air to the outdoors is provided separately, and a damper is installed in the high-temperature flow path and the low-temperature flow path to adjust the cross-sectional area of each. A rainwater cover provided with a heater that is energized with the damper reducing the cross-sectional area of the high-temperature flow path and the low-temperature flow path. (2) The rainwater cover according to claim 1, wherein the damper and the heater are configured to be automatically controlled according to the temperature of outdoor air.
