Abstract: A filter cooling construction includes a mass of filtration material held in a filter body and a cooling member extending in the mass of filtration material. A manifold communicates with the cooling member for channeling a cooling fluid to the cooling member. In another embodiment, a heat transfer construction is provided so that a temperature control fluid can flow to the heat transfer member thereby selectively heating and cooling the mass of filtration material. Once use for such constructions is in air filters.

Abstract: An air filtering system for an enclosure that additionally heats and/or cools one or more regenerative beds of a regenerative thermal swing absorption (TSA) component of the system includes a closed loop indoor temperature adjusting circuit having a compressor, an outdoor heat exchanger, an indoor heat exchanger, and an expansion valve disposed therealong for conditioning air of the enclosure. At least one diversion line of the temperature adjusting circuit passes through the one or more regenerative beds for at least one of heating or cooling the one or more regenerative beds.
