Thermal barrier for air handler (AHU) cabinet

摘要

A panel for use in an air handling unit that conducts air along an enclosed path of travel. The panel includes a rectangular shaped frame made of a plastic material having a low thermal conductivity. The frame is closed by top and bottom cover plates having skirts that are contained in top and bottom channels that encircle the inside of the frame and thus establish an enclosed cavity within the panel. A curable polyurethane foam is injected into the cavity to fill the cavity. The foam sets to bond the covers to the frame and to provide a thermal barrier that impedes the flow of heat through the panel.
