An air dehumidifying and conditioning system (20) draws incoming air (32) through a fan (40) and uses heat from the fan (40) and fan motor (48) to heat air discharged from the fan. The system then divides air discharged from the fan into a supply stream (50) and a scavenge stream (52). The supply st

An air dehumidifying and conditioning system (20) draws incoming air (32) through a fan (40) and uses heat from the fan (40) and fan motor (48) to heat air discharged from the fan. The system then divides air discharged from the fan into a supply stream (50) and a scavenge stream (52). The supply stream is passed through a pre-cooler (60A) and an air cooler (60) for cooling and dehumidification. If necessary, the scavenge stream is heated with a pre-heater (62A) and a supplemental heater (62). The dehumidified air of the supply stream (50) is then heated by passing through a heat exchanger (80), with the heating by the heat exchanger being accomplished using the scavenge stream (52). Should no heating, cooling, or dehumidifying be required, a bypass stream (54) formed from the scavenge stream (52) is transmitted to the conditioned space.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] A method of dehumidifying and heating air for supply to a conditioned space, the method comprising:dividing an input stream of warm and moist air at atmospheric pressure obtained externally to the conditioned space into a scavenge stream and a supply stream and insuring that the scavenge stream and supply stream are not subsequently mixed, the warm and moist air obtained externally having a greater moisture content than a desired moisture content of air in the conditioned space;controlling volume of the scavenge stream in dependence upon temperature of the input stream;cooling and dehumidifying the supply stream;using enthalpy of the scavenge stream to reheat the supply stream without adding moisture from the scavenge stream to the supply stream, and thendirecting the reheated supply stream to the conditioned space.
