Abstract
Ultraviolet radiation is directed within an area. The target wavelength ranges and/or target intensity ranges of the ultraviolet radiation sources can correspond to at least one of a plurality of selectable operating configurations including a sterilization operating configuration and a preservation operating configuration.
Claims20
A system comprising:
- at least one ultraviolet radiation source configured to generate ultraviolet radiation directed within a storage area;
- a chamber located within the storage area and configured to store a gas;
- and
- means for monitoring and controlling the at least one ultraviolet radiation source and the storage area, the means including:
- monitoring, using data received from a visual camera and a chemical sensor, a set of current conditions of at least one of:
- the storage area or a set of items located in the storage area, wherein the set of current conditions includes a level of ethylene gas within the storage area and a change in a visual appearance of at least one of:
- the storage area or the set of items located in the storage area;
- reducing the level of ethylene gas within the storage area based on the set of current conditions by circulating air from the storage area to the chamber;
- and
- controlling ultraviolet radiation generated by the at least one ultraviolet radiation source using at least one of a plurality of selectable operating configurations and the set of current conditions including the level of ethylene gas within the storage area, the selectable operating configurations including:
- a sterilization operating configuration, a preservation operating configuration, and a condition monitoring operating configuration, wherein the sterilization operating configuration is configured to disinfect the storage area, the preservation operating configuration is configured to provide a particular level of repression for microorganism growth, and the condition monitoring operating configuration is configured to detect microorganisms within the storage area,
- wherein the controlling includes adjusting at least one of:
- a location within the storage area to which the ultraviolet radiation is directed, a direction of the ultraviolet radiation emitted by the at least one ultraviolet radiation source, or a time scheduling of the ultraviolet radiation emitted by the at least one ultraviolet radiation source.
