Patent ID: 8419840

Claim:
An air-conditioning system that supplies a gas to a space to be air-conditioned and/or discharges a gas from the space to be air-conditioned through a permeable membrane; wherein the permeable membrane is an asymmetric membrane made of a polymeric material prepared by polymerizing a monomer composition containing a monomer represented by Formula (1): wherein each R 1 is independently a C 1-12 alkyl group and/or a C 6-10 aryl group, X is a group represented by Formula (i) and/or a group represented by Formula (ii): wherein each R 2 is independently a C 1-12 alkyl group, d is an integer of 1 to 5, and c is an integer of 3 to 5; a is an integer of 1 to 3, and b is an integer of 0 to 2; and wherein the polymeric material is an addition polymer prepared by addition polymerization of a monomer composition containing the monomer represented by Formula (1).
