Abstract
A system and method for providing conditioned air to the interior space of a building includes separate dehumidification and sensible cooling functions. The separate dehumidification allows for much higher supply air temperatures, preferably within about 10.degree. F. to about 15.degree. F. of the air temperature of the building space. Low-velocity air distribution through a ceiling plenum or a vent into the space allows for very low fan static pressures, which greatly reduces fan energy usage compared to conventional ducted systems. The low static pressures and high supply-air temperatures allow the use of existing drop ceiling construction with little modification. Optional return air channels between an inner glazing and an outer glazing of exterior windows can virtually eliminate heating loads at the building perimeter, which virtually eliminates the need for simultaneous heating and cooling. The result is a major improvement in energy efficiency and comfort while reducing installed cost of the system.
