ABSTRACT:
An apparatus for supplying conditioned air at a substantially constant temperature and humidity. The apparatus includes a supply duct coupled to a source of supply air for carrying the supply air therethrough. A return duct is coupled to the supply duct for carrying return conditioned air therethrough. A temperature reducing device is coupled to the supply duct for decreasing the temperature of the supply and return conditioned air. A by-pass duct is coupled to the supply duct for selectively directing portions of the supply and return conditioned air around the temperature reducing device. Another by-pass duct is coupled to the return duct for selectively directing portions of the return conditioned air around the supply duct and the temperature reducing device. Controller devices selectively control the flow and amount of mixing of the supply and return conditioned air flowing through the temperature reducing device and within the supply duct, the return duct, the by-pass duct and the another by-pass duct whereby the temperature and humidity of the conditioned air is maintained substantially constant. A circulating mechanism moves the supply air, the return conditioned air, and the conditioned air through the supply duct, the return duct, the by-pass duct, and the another by-pass duct.
