Desiccant assisted air conditioner

DETAILED DESCRIPTION I claim: 1.
A desiccant assisted air conditioning system for delivering dehumidified refrigerated supply air into a conditioned space and with return therefrom divided between recirculation air and exhaust - relief air employed to remove heat resulting from dehumification and employing waste heat from refrigeration for desiccant regeneration, and including; a first outside air inlet duct inducting minimum outside air through a dehumidifying section of a desiccant dehumidifying means, a second outside air inlet duct inducting maximum outside air and connected into said first duct for mixing with the air conducted through the dehumidifier means and delivering mixed air through a cooling coil of a refrigeration means, a blower means for circulating the mixed air through the cooling coil and through a third supply air duct opening into the conditioned space, the refrigeration means being comprised of a compressor means delivering liquid refrigerant through a condenser coil for discharge of waste heat and through means for expansion in said cooling coil and return to the compressor means as a gas, a fourth return air duct from the conditioned space and connected into said second outside air inlet duct downstream from a damper and control means therein to regulate volume inlet of maximum outside air and volume recirculation of return air, a fifth relief air duct from the conditioned space and conducting conditioned space air through an evaporative air cooling means and discharging to exhaust through a heat exchanger means passing and cooling heated air from the dehumidifying section of the dehumidifying means upstream of said mixing with air delivery through the cooling coil, a sixth outside air duct and blower means delivering air through the condenser coil of the refrigeration means for the absorption of waste heat and conducting the same through a desiccant regenerating section of the dehumidifying means and to exhaust, and control means coordinating the damper and control means and operation of the dehumidifying means and refrigeration means
