The XCO Flow Controller

Traditional heating and cooling systems operate by supplying and returning air at fixed locations from overhead. Thermal stratification develops due to the buoyancy of warm air, especially in spaces with tall ceilings. In cooling, the traditional system will lead to higher return air temperatures than necessary. In heating, the traditional system will lead to overheating the unoccupied upper portion of the space. The traditional system, therefore, has limitations and consumes more energy to meet building needs.

The XCo Flow Controller easily integrates with traditional, overhead systems by introducing flexibility for where air is supplied and returned. In cooling, air is supplied low in the occupied zone and returned at a middle level. The goal in cooling is to only condition the occupied space, letting the upper zone stratify thereby reducing the overall cooling demand. In heating, air is supplied near the ceiling and returned near the floor. The goal in heating is to create a well-mixed space by drawing down warm air from the ceiling and removing cold air from the occupant level.
