<p>PROBLEM TO BE SOLVED: To reduce the cost and to miniaturize the device, while oxygen-rich air is smoothly generated by an air quality activation device provided with an adsorbent enabling adsorbing and desorbing nitrogen. SOLUTION: This device generates the oxygen-rich air by forcibly feeding air to the adsorbent 54 enabling to adsorb and desorb the nitrogen, and is provided with at least two adsorption tanks 21, 22 respectively sealed the adsorbents 54, an air pump 13 for forcibly feeding sucked air to respective adsorption tanks 21, 22, a cooling coil 16 for cooling the air discharged from the air pump 13, a heat exchange fin 16F attached to the cooling coil 16, and a flow path control means for alternately switching respective adsorption tanks 21, 22 to an adsorption process or a desorption process by switching a flow path of the air discharged from the cooling coil 16 and also making one of the adsorption tanks 22, 21 to the desorption process in the case that either one of the adsorption tanks 21, 22 is made to the adsorption process. The flow pass control means feeds one portion of the oxygen-rich air generated at the adsorption tanks 21, 22 during the adsorption process to the adsorption tanks 22, 21 during the desorption process.</p> |
