<p>PURPOSE:To save energy and to reduce running cost by furnishing an oxygen adsorption/desorption material to a revolving body and providing an air cooling means and a heating means. CONSTITUTION:An opening is formed in the wall 1 partitioning the inside of a chamber from the outdoor, and a revolving body 2 driven by a motor M is provided so as to close the opening of the wall 1, and the main part of the revolving body 2 is made of the oxygen adsorption/desorption material 2a. The part of the oxygen adsorption/desorption material 2a facing the space X of the outdoor is cooled with the natural air to such a temp. that it is allowed to adsorb oxygen, and the part facing the space Y of the inside of the chamber is heated with an electric heater 3 to such a high temp. that it is allowed to desorb the oxygen, so that the oxygen adsorbed from the outdoor atmosphere by the action of the adsorption/desorption material 2a is desorbed in the space Y of the inside of the chamber as the revolving body 2 is driven, which prevents the concn. of oxygen in the camber from being lowered. By this method, the energy efficiency is improved.</p> |
