Abstract:
A method for providing cooling air to a passenger cabin of a motorized vehicle, comprising generating cooling air by:(a) directing high temperature air into a desiccant-based moisture collector, the high temperature air having a temperature sufficient to evaporate moisture from desiccant of the moisture collector and into the high temperature air so that humidified air exits the moisture collector;(b) directing the humidified air from the moisture collector into a condensation section of an evaporator/condenser unit to condense moisture from the humidified air onto a surface of the evaporator/condenser unit;(c) directing low temperature air into the moisture collector, the low temperature air having a temperature low enough that the desiccant of the moisture collector collects moisture from the air and dehumidified air exits the moisture collector;(d) directing the dehumidified air through a heat exchanger to cool the dehumidified air;(e) directing the cooled, dehumidified air through an evaporator section of the evaporator/condenser unit to humidify and further cool the air to produce a cold, moist air stream; and(f) directing the cold, moist air stream into the passenger cabin of the motorized vehicle.
