Claims15
Apparatus for conditioning air comprising;
- a housing forming a pair of parallel passages having a common wall therebetween, means for moving air through said passages, heat exchange means disposed in one of said passages to form a heat exchange passage, the other of said passages forming a bypass passage, a pair of air gates controlling the opening and closing of said pair of passages, respectively, each of said air gates being supported for movement between open and closed positions at walls of said passage spaced from said common wall;
- and means connecting said pair of air gates together for simultaneous movement equal distances and in opposite directions with one of said air gates movable from an open to a closed position while the other of said air gates is moved from a closed toward an open position, said air gates being shaped to maintain a uniform opening therebetween for the passage of air from said pair of passages for all positions of said air gates.
