Abstract: A control system for ambient air exchange with a machine room or similar enclosure controls an exchange rate of the ambient air based on a temperature differential between the inside (machine room) and outside temperatures, rather than absolute thermostatic controls based solely on the interior temperature. A larger temperature difference between the inside and outside air means a greater cooling potential for the exchanged air. Ambient air exchange is performed by dampers/louvers/vents and a fan speed driving the air exchange. Control of the fan speed based on the temperature differential allows lower fan speeds for controlling the temperature when the temperature differential indicates ample cooling. Higher fan speeds, incurring additional electrical consumption and fan noise, are only needed when a relatively small differential limits the cooling ability of the exchanged air.
