ABSTRACT:
Cooling air to be provided to a passenger cabin of a motorized vehicle is generated using a desiccant-based moisture collector, a heat exchanger, and an evaporator/condenser unit, such as a rotating evaporator/condenser wheel. High temperature air that has a temperature sufficient to evaporate moisture from desiccant of the moisture collector and into the air is directed into the moisture collector so that humidified air exits the moisture collector. The humidified air is directed into a condensation section of the evaporator/condenser unit so that moisture condenses from the humidified air onto a surface of the evaporator/condenser unit. 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 is directed into the moisture collector. The dehumidified air is directed through a heat exchanger to cool the dehumidified air, and the cooled, dehumidified air is directed through an evaporator section of the evaporator/condenser unit to humidify and further cool the air to produce a cold, moist air stream that is directed into the passenger cabin of the motorized vehicle.
