摘要：Apparatus for supplying treated air to an enclosure, including heat exchanger through which a heat exchange medium flows and a fan arranged to route air to be treated over the heat exchanger in heat transfer relation with the medium. The temperature of the air in the enclosure is sensed and the area of the outlet provided for discharging the treated air into the enclosure is modulated in response to the temperature of the enclosure. A variable control signal, the magnitude thereof being related to the area of the outlet, is generated and is supplied to a control operable to vary the speed of the fan motor to maintain a substantially constant static pressure in the air passage regardless of the area of the outlet, to maintain a substantially constant discharge velocity.
