COUNTER-FLOW ENERGY RECOVERY VENTILATOR (ERV) CORE

摘要

A heat and humidity exchanger has example application in exchanging heat and water vapour between fresh air entering a building and air being vented from the building. The heat and humidity exchanger has a self-supporting core formed from layered sheets (710, 720) of a moisture-permeable material. Plenums (750) are arranged to direct fluid streams into and out of the core. The plenums (750) may be on opposing sides of the core to permit counterflow exchange of heat and water vapour. The plenums (750) are attached to the core along opposite edges of the sheets (710, 720).

主权项

1. A heat and humidity exchanger comprising:
a core comprising a plurality of water vapor-permeable sheets, the sheets layered and at least some of the sheets pleated to provide a plurality of groups of channels extending through the core, each of the plurality of groups of channels comprising channels defined between two adjacent ones of the sheets and extending along the pleats of at least one of the pleated sheets, a plurality of plenums formed on opposed sides of the core, the plenums on each of the opposed sides of the core configured such that the channels of groups of channels on opposing sides of the same one of the sheets are fluidly connected to different ones of the plenums; wherein the plenums are defined at least in part by manifold members attached along opposite edges of the sheets, at least one of the manifold members comprising a sheet that is connected to and follows an edge of one of the pleated water vapor-permeable sheets.
