Abstract
Abstract The switchover valves are actuated in a predetermined timelag sequence so that the storeroom air can first push out residual desorption gas from the container and outflow conduits before being recycled after washing to the storeroom. In the same manner, during a regeneration period, the incoming fresh air initially pushes the residual storeroom air into the storeroom before being vented to the atmosphere.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
20 words
A process as set forth in claim 1 wherein said adsorption period and said regeneration period are repeated in sequence.
Claim 2
Dependent Claim
29 words
A process as set forth in claim 1 which further comprises the step of at least intermittently heating the desorption medium prior to passing into the solid adsorption medium.
Claim 3
Dependent Claim
34 words
A process as set forth in claim 1 wherein the gaseous component is carbon dioxide, the gas mixture is air from a storeroom containing fruit and vegetation, and the desorption medium is fresh air.
Claim 4
Independent Claim
231 words
An apparatus for adsorbing at least one gaseous component from a gas mixture in an enclosed room comprising at least one adsorption means having an absorption medium for adsorbing the gaseous component from the gas mixture; a first inflow conduit connected to said means for passing the gas mixture from an enclosed room into said means; a second inflow conduit connected to said means for passing a gaseous desorption medium into said means; a first switchover valve connected to said first and second inflow conduits and to said means for selectively communicating one of said conduits to said means; a first outflow conduit connected to said means for returning the gas mixture into the enclosed room; a second outflow conduit connected to said means for passing the gaseous desorption medium from said means to atmosphere outside the enclosed room; a second switchover valve connected to said first and second outflow conduits and to said means for selectively communicating one of said outflow conduits to said means; at least one blower for forcing the gas mixture and desorption medium through said means; and retardation means connected to said valves to sequentially switchover said second valve from one of said outflow conduits to the other of said outflow conduits with a predetermined timelag after said first valve is switched over from one of said inflow conduits to the other of said inflow conduits.
Claim 5
Dependent Claim
41 words
An apparatus as set forth in claim 5 further comprising a pair of adsorption means connected in parallel between said valves whereby said means alternately adsorb the gaseous component from the gas mixture and regenerate the adsorption medium in alternating sequence.
Claim 6
Dependent Claim
17 words
An apparatus as set forth in claim 5 wherein said retardation means is an electrical retardation means.
Claim 7
Dependent Claim
17 words
An apparatus as set forth in claim 5 wherein said retardation means is a pneumatic retardation means.
Claim 8
Dependent Claim
17 words
An apparatus as set forth in claim 5 wherein said retardation means is a mechanical retardation means.
Claim 9
Dependent Claim
17 words
An apparatus as set forth in claim 5 wherein said retardation means is a hydraulic retardation means.
Claim 10
Dependent Claim
15 words
An apparatus as set forth in claim 5 wherein said adsorption medium is active carbon.
Claim 11
Dependent Claim
14 words
An apparatus as set forth in claim 5 wherein said absorption medium is zeolite.
