1. A HVAC system, comprising:
(a) a plurality of air suppliers for creating a first air stream, a second air stream, and a third air stream;
(b) a cooling means positioned within the first air stream;
(c) a heating means positioned within the third air stream;
(d) an energy recovery wheel defining a regeneration side and a process side, wherein the process side is positioned in the first air stream at a position upstream of the cooling means, and wherein the regeneration side is positioned in the second air stream;
(e) a desiccant wheel defining a regeneration side and a process side, wherein the process side is positioned in the first air stream at a position downstream of the cooling means, and wherein the regeneration side is positioned partially within the second air stream and partially within the third air stream at a position downstream of the heating means;
(f) a first connecting passageway fluidly connecting the second air stream and the first air stream.
