A central air handling and conditioning apparatus is provided with a by-pass dehumidifier for maintaining the temperature of the air in a plurality of enclosed spaces within a predetermined range and the relative humidity of the air below a predetermined value. The apparatus includes an air conditioner for regulating the temperature of the air, a dehumidification means for regulating the relative humidity of the air and an air handler for circulating the conditioned and dehumidified air through the enclosed spaces. The air conditioner is a conventional forced-air furnace or heater, an air-conditioner, an evaporative cooler, or a fan or blower for heating or cooling the air and returning the air to the enclosed spaces. The dehumidification means is a modified dehumidifier for removing water vapor from the air. The air handler includes a conventional air circulation means which may be, for example, the blower of the air conditioner. A controller automatically controls the operation of the air circulation means and the air conditioner, and the air circulation means and the dehumidification means as required to maintain the temperature of the air within a predetermined range and the relative humidity of the air above a predetermined value.
