OXYGEN ENRICHMENT DEVICE, CONTROL METHOD, AND CONTROL PROGRAM

Title:

OXYGEN ENRICHMENT DEVICE, CONTROL METHOD, AND CONTROL PROGRAM

Document Type and Number:

WIPO Patent Application WO/2022/186174

Kind Code:

A1

Abstract:

Provided are: an oxygen enrichment device that can inhibit a reduction in the internal pressure of an enriched oxygen gas tank in order to discharge enriched oxygen gas at a set flow rate; a control method; and a control program. Provided is an oxygen enrichment device that can, before a pressure equalization step, preliminarily start increasing the pressure of adsorption cylinders in which pressure has been reduced, thereby inhibiting a reduction in the pressure of both cylinders during the pressure equalization step and as a result inhibiting a reduction in the internal pressure of an enriched oxygen gas tank.
