  • Sheet for total heat exchanger
    Patent number: 8383526
    Abstract: A liquid containing a hydrophilic polymer is applied by spreading or impregnation to a porous sheet comprising paper or a nonwoven fabric containing not less than 30% by weight and not more than 100% by weight of hydrophilic fiber to provide a hydrophilic polymer-processed sheet of which the surface and/or the interior of the porous sheet is filled with the hydrophilic polymer, which is made insoluble to water. This sheet is used as a sheet for a total heat exchanger which has higher conductivity of sensible heat and latent heat than conventional sheet for a total heat exchanger that uses a moisture permeable membrane.
    Type: Grant
    Filed: June 4, 2007
    Date of Patent: February 26, 2013
    Assignees: Rengo Co., Ltd., Frontier Industrial Co., Ltd.

  • Air filter
    Patent number: 6916363
    Abstract: An air filter in which a thick sheet of textile of three-dimensionally knitted synthetic fiber thread is sliced at a middle position in a thickness direction and separated into a front face and a rear face. The front face or the rear face is one face side, and many short fibers are protruding from another face side. Further, the air filter is electrified as a whole.
