Abstract:
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.
