Multi-layer panels, partitions for heat exchangers, heat exchangers and ventilation equipment including heat exchangers

Abstract

The proposed design features multi-layered panels with low air permeability and excellent moisture permeability; partitions for the main heat exchanger unit include multi-layered panels; the main heat exchanger unit is provided with multiple partitions for the main heat exchanger unit; and the ventilation equipment is supplied with the main heat exchanger unit. The multilayered sheet according to the design is supplied with a porous substrate and a moisture-permeable membrane is placed on one side of the interlayer, the moisture-permeable membrane is supplied with a porous substrate and the moisture-permeable membrane is placed on at least one side of the porous substrate, and the moisture-permeable membrane is made of a thermoplastic copolymer with stable chains containing hydrophilic groups as functional groups.
