Patent number: 7101414Abstract: A method of reducing the sorbate concentration of a process fluid stream using a sorption bed system includes the following steps. A mass of a sorbent material is rotated so that, in a cycle of operation, a given volume of the sorbent mass sequentially passes through first, second, third, fourth, fifth, and sixth zones, before returning to the first zone. A process fluid stream is passed through the sorbent mass in the first zone, and a regeneration fluid stream is passed through the sorbent mass in the fourth zone. A first isolation fluid stream is recycled in a closed loop, independent of the process fluid stream and the regeneration fluid stream, between the sorbent mass in the second zone and in the sixth zone. A second isolation fluid stream, meanwhile, is recycled in a closed loop, independent of the process fluid stream, the regeneration fluid stream, and the first isolation fluid stream, between the sorbent mass in the third zone and in the fifth zone.Type: GrantFiled: April 27, 2004Date of Patent: September 5, 2006Assignee: Munters CorporationInventors: Paul A.

Patent number: 7047751Abstract: A method for conditioning air for an enclosure in which a supply air stream is cooled with a refrigerant system containing a variable compressor by passing the air over a cooling coil to reduce the temperature thereof; the thus cooled supply air stream is then passed through a segment of a rotating desiccant wheel under conditions which increase its temperature and reduce its moisture content, and then delivered to the enclosure. The desiccant wheel is regenerated by heating a regeneration air stream with the condensing coil of the refrigerant system, and then passing the heated regeneration air stream through another segment of the rotating desiccant wheel. At least one condition of the supply air stream, the regeneration air stream, and/or the refrigerant system is sensed or monitored and the output of the compressor is controlled in response to the sensed condition.Type: GrantFiled: October 25, 2004Date of Patent: May 23, 2006Assignee: Munters CorporationInventors: Paul A.

Patent number: 6622508Abstract: An apparatus and method for heat and humidity exchange between two air streams, one hot and one humid. A first of the air streams is fed from the interior of a building to the ambient air and a second of the air streams is fed from the ambient air to the interior of the building. The first air stream is cooled and transferred through a heat exchanger, to a heater and a dehumidifier before being exhausted to the ambient air. The second air stream is transferred through the dehumidifier and the heat exchanger, whereupon it is cooled in a cooling device before being transferred into the interior to the building. Before being fed to the dehumidifier, the second air stream is caused to exchange heat and humidity with the first air stream before the latter is fed into the heat exchanger.Type: GrantFiled: March 25, 2002Date of Patent: September 23, 2003Assignee: Munters Europe ABInventors: Paul A.

Patent number: 6557365Abstract: A method and apparatus for conditioning air for an enclosure is disclosed in which a supply air stream, preferably from the atmosphere is cooled by the cooling coil of a refrigerant cooling system to reduce the temperature and humidity thereof to first predetermined level. The thus cooled and dehumidified air is then passed through a segment of a rotating desiccant wheel under conditions which reduce moisture content and increase temperature to a second predetermined temperature range. The supply air is then delivered from the desiccant wheel to the enclosure. The desiccant wheel is regenerated by heating a separate regeneration air stream, also preferably from the atmosphere, using the condensing coil of the refrigerant system in order to increase the regeneration air stream temperature to a third predetermined temperature range. The thus heated regeneration air stream is then passed through another segment of the rotating desiccant wheel to regenerate the wheel.Type: GrantFiled: February 28, 2001Date of Patent: May 6, 2003Assignee: Munters CorporationInventors: Paul A.
