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.
Claims21
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
- a monitoring and control system configured to:
- monitor a set of current conditions of at least one of:
- the storage area or a set of items located in the storage area;
- calibrate exposure of at least one of:
- the storage area or the set of items, to the gas based on the set of current conditions by circulating air from the storage area to the chamber;
- and
- control 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, 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.

- a storage area configured to store at least one refrigerated item;
- a component configured to control at least one environmental condition of the storage area, wherein the at least one environmental condition includes at least one of:
- a temperature, a humidity, a gas convection, or a fluid convection;
- at least one ultraviolet radiation source configured to generate ultraviolet radiation directed within the storage area;
- a chamber located within the storage area and configured to store a gas;
- and
- a monitoring and control system configured to:
- monitor a set of current conditions of at least one of:
- the storage area or a set of items located in the storage area;
- calibrate exposure of at least one of:
- the storage area or the set of items, to the gas based on the set of current conditions by circulating air from the storage area to the chamber;
- and
- control 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, 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.
