A ventilation and dehumidification system for ventilating fresh air to a conditioned space. The system is comprised of a unitary heat transfer desiccant wheel for dehumidifying incoming air by exchanging moisture from an inflow current of air with an outflow current of air. The unitary heat recovery wheel is able to transfer heat between the two air currents when the wheel is spun at a faster speed. The unitary heat transfer desiccant wheel is both regenerated and defrosted by a regenerative heater which is placed to heat the outflow current of air before the outflow current passes through the unitary heat transfer desiccant wheel. The unitary heat transfer desiccant wheel is spun at a slow speed to accomplish more dehumidification, and at a fast speed to accomplish more heat recovery. The system includes at least two blowers in order to motivate the inflow and outflow currents of air. The blowers can be arranged so as to create an air pressure differential between the inflow chamber and the outflow chamber so that any leakage of air between the two chambers will occur from the inflow chamber to the outflow chamber.

1. A method of ventilating fresh air to a conditioned space by exchanging heat and moisture with exhaust air, the method comprising the steps of:(a) providing a heat transfer desiccant wheel capable of transferring both heat and moisture between the fresh air and the exhaust air, (b) selecting a preferred speed at which to rotate the heat transfer desiccant wheel to maximize either heat transfer or moisture transfer, (c) rotating the heat transfer desiccant wheel at the preferred speed, (d) introducing both fresh air and exhaust air to the heat transfer desiccant wheel thereby transferring heat and moisture between the fresh and exhaust air, (e) directing the fresh, conditioned air to the conditioned space, and (f) expelling the stale exhaust air; whereby the conditioned space is ventilated with dehumidification and heat recovery accomplished efficiently by the same rotating wheel which is rotated at differing speeds to maximize dehumidification or heat recovery.
