ABSTRACT:
A dehumidification and energy recovery device includes a casing defining an interior that is divided into two vertically stacked sections, a channel extending vertically between the sections and forming upper and lower openings, absorption devices arranged inside the channel corresponding to the sections respectively, and a tank arranged below the lower opening of the channel and containing a liquid that is driven by a pump to a position above the upper opening of the channel to drop onto and flow through the absorption devices. Intake airflow and exhaust airflow respectively pass through the sections, contacting the liquid flowing through the channel in a cross-flow fashion, whereby exchange of humidity and heat is performed between the airflows and the liquid to effect dehumidification and energy recovery with a simple structure and low costs.
