Abstract:
1. A control system for use in a gastight storage facility containing a bulk perishable commodities comprising: a test enclosure disposed within the gastight storage facility defining an interior space of sufficient size to hold a representative sample of the commodities; an atmosphere valve selectively movable between an open position in which said interior space is in atmospheric communication with the gastight storage facility, whereby the representative sample of commodities in the interior space and the bulk of commodities in the gastight storage facility are subject to common atmospheric conditions, and a closed position in which said interior space is isolated from the gastight storage facility, whereby the representative sample of the commodities can be subjected to different atmospheric conditions than the bulk of the commodities in the gastight storage facility; and a controller for dynamically controlling the atmosphere in the gastight storage facility, said controller configured to control said atmosphere valve to selectively isolate said interior space from the gastight storage facility, said controller configured to determine a dynamic control value by analyzing atmosphere within said interior space while said enclosure is in isolation from said gastight storage facility, said dynamic control value derived from a response of the representative sample of commodities to changes in atmosphere within said interior space, said controller configured to control the atmosphere in the gastight storage facility as a function of said determined dynamic control value.
