DEVICE PROVIDED WITH MOISTURE-ABSORBING/RELEASING MEMBRANE, WATER VAPOR SEPARATOR PROVIDED WITH DEVICE HAVING MOISTURE-ABSORBING/RELEASING MEMBRANE, AND HEAT EXCHANGER

摘要

[Problem] To provide a technique for high-efficiency exchange of water vapor and heat (ventilation) without any incidence of air admixing in a highly sealed/heat-insulated residence, office, factory, etc., liable to cause adverse effects on health, as in sick house syndrome, etc. [Solution] Heat is exchanged using a device (10) provided with a moisture-absorbing/releasing membrane in which is formed a membrane portion (13) that includes a water-vapor permselective moisture absorbing/releasing agent (14) in the openings (12) of a plate member (11) used as a carrier. Using this structure, heat exchange is performed allowing the movement of moisture between air from inside and air from outside even while toxic substances such as carbon dioxide or ammonia are blocked.
