Adsorption / desorption element, carbon dioxide concentration adjusting device using the same, carbon dioxide concentration adjusting system, and carbon dioxide concentration adjusting method.

摘要

PPROBLEM TO BE SOLVED: To provide an adsorption-desorption element, and a carbon dioxide concentration control device, system, and a method which enables the control of the concentration of carbon dioxide in room air while reducing thermal energy loss with a simple structure without necessarily requiring heating. PSOLUTION: The adsorption-desorption element is used for adsorbing and desorbing carbon dioxide in air by ventilating air containing carbon dioxide. The adsorption-desorption element contains a material having the function of adsorbing and desorbing carbon dioxide. In the case where air containing carbon dioxide is ventilated to the adsorption-desorption element, the adsorption-desorption element adsorbs carbon dioxide when the concentration of carbon dioxide in the ventilated air increases at an air temperature within a range of -10 to 50C, and desorbs carbon dioxide when it decreases. The carbon dioxide concentration control device, system, and method use the adsorption-desorption element. PCOPYRIGHT: (C)2009,JPO&INPIT
