ABSTRACT:
The present invention provides an air-handling unit that can supply air, to a desired space, which is cold, which is cooler than the set point of the thermostat for that space and hence is referred to as cool air, which is warmer than that set point and hence is referred to as warm air, or which is hot. That unit can operate even when very low pressure air is supplied to it; and hence it is connectable to a conventional low pressure cold air duct. That unit may have a heat source incorporated into it, may utilize air from that space which is cooler than that set point and hence can be referred as cool air, and may utilize air from that space which is warmer than that set point and hence can be referred to as warm air. Dampers in that unit control the amount of cold air and cool air that is supplied to that space, and a blower and the heat source in that unit control the amount of warm air and hot air which is supplied to that space. Backdraft dampers in that unit permit aspiration of cool or warm air, but can substantially prevent the escape of any air from that unit even if a super-atmospheric downstream pressure develops.
