Abstract
Barometric-pressure data that a barometric pressure sensor outputs, and an air volume data that an air-volume sensor outputs are input into a system control circuit. The system control circuit is provided with a table storing portion. In the table storing portion, a control table is stored. The control table defines a voltage value to be added to a fan power supply set by a barometric-pressure value and an air-volume value. The voltage value to be added is voltage added to a normally set voltage value, and is set within a range from 0 (zero) V (volt) to 6 V, for example. The normally set voltage value is voltage set based on temperature detected by a temperature sensor, for example. In this case, the voltage value to be added is applied to voltage that is determined by the outside temperature and applied to the fan power supply.
