Abstract: The dehumidifier uses an all-plastic air-to-air heat exchanger together with an integral chiller to cool the incoming air to remove water vapor, and then exchange heat with incoming air to cool the incoming air and re-heat the outgoing air. The degree of dehumidification and the temperature of the outgoing air can be controlled by varying the speed of a variable speed fan so as to provide varying degrees of cooling as well as dehumidification. A programmable controller can be used to operate the dehumidifier automatically, either together with a humidistat and thermostat, or in accordance with a predetermined time profile for the conditioned space.
