Patent number: 9033030Abstract: An apparatus and method for minimizing cold spots on plates of a plate-type fluid-to-fluid heat exchanger averages the plate temperature at a hot-fluid exit plane of the heat exchanger. The heat exchanger matrix is constructed to internally vary the flow patterns of opposing hot and cold fluid streams so that the heat transfer coefficient values of one or both fluid streams, designated as h, are optimized so the hot fluid value is a greater value than that of a cold fluid value. Plate variable flow structures are arranged in a manner that allows higher velocity hot fluid flow and possible lower velocity cold fluid flow in areas where the plate temperatures are coolest and the opposite configuration where plate temperatures are hottest.Type: GrantFiled: August 26, 2009Date of Patent: May 19, 2015Assignee: MUNTERS CORPORATIONInventor: Nicholas H. Des Champs

Patent number: 8631661Abstract: A method and apparatus for conditioning ambient air for use in an enclosure is disclosed which cools the ambient supply air stream in sensible energy recovery device or cools and dehumidifies the ambient supply air stream in an enthalpy energy recovery device. The thus cooled air is then cooled by a cooling coil of a refrigerant cooling system to reduce its temperature and humidity. The thus cooled and dehumidified air is then passed through a segment of a rotating desiccant wheel or through a different type of desiccant dehumidification device under conditions which reduce its moisture content and increases its temperature. 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, provided by the exhaust air from the space and using the condensing coil of the refrigerant system to increase the regeneration air stream temperature.Type: GrantFiled: February 13, 2009Date of Patent: January 21, 2014Assignee: Munters CorporationInventors: Peter Teige, Michael Hayes
