Abstract: A reverse flow dehumidifier system for dehumidifying a conditioned space is provided. The system includes a housing having: a static desiccant block fixedly coupled to the housing and comprising a desiccant media; a fan configured to direct outside air across the desiccant media during a first operating phase and a second operating phase and configured to direct conditioned air across the desiccant media during a third operating phase. The system further includes a control system operatively coupled to at least one of the fan, and which includes a plurality of sensors selectively positioned inside the housing and inside the conditioned space, the plurality of sensors are configured to measure at least one air parameter of the outside air during the first operating phase and configured to measure the at least one air parameter of the conditioned air during the third operating phase.

Abstract: A circuit for turning OFF a thyristor. The circuit includes at least one first circuit element configured to provide a high reverse turn-OFF voltage to the thyristor gate for a predetermined period of time. Immediately following the predetermined period of time, at least one second circuit element provides a normal reverse turn-OFF voltage to the thyristor gate. The normal reverse turn-OFF voltage is substantially lower than the high reverse turn-OFF voltage.

Abstract: An air chamber for the housing of air handling components including an interior shell surrounded by an exterior shell, the shells being separated by materials of relatively low thermal conductivity. The interior shell is peripherally mounted on an interior base. The interior base is disposed within an exterior base that supports the exterior shell. A structural thermal insulation material is disposed interstitially between the interior and exterior bases and the interior base and interior shell are thermally isolated from the exterior base and exterior shell.

Abstract: A two-piece panel molding having an L-shaped base which is attached to a support through a foamed adhesive tape. The base has an upright retaining flange at one side to abut a marginal facing edge on a panel and a slot at an opposite side. The thickness of the base is substantial to comfortably accommodate the slot and to provide rigid support therefor. A plurality of upwardly opening channels are formed in the base. A retainer has a panel retaining means to abut an opposite facing edge of the panel and has a locking flange which fits within the slot of the base. Means, for example, complementary serrated edges in the locking flange and the slot, retain the locking flange adjustably within the slot. The panel engaging retaining means can comprise a single flange to retain a thick panel or a lateral web with one or more depending flanges to retain thinner panels.
