A method and system is provided which receives a desired humidity level from a user for the refrigeration compartment of a refrigerator, determines the current humidity level, and then activates an atomizer in the refrigeration compartment to increase the humidity level if needed. The humidity in the refrigeration compartment may be determined based at least in part on the temperature of the refrigeration compartment, the defrost timer, the door opening times, and the compressor timer.

1. A method for actuating a humidifier to provide humidification to the interior of a refrigeration compartment, said method including: storing a predetermined desired humidity level for the interior of the refrigeration compartment;measuring the temperature in the interior of said refrigeration compartment;determining the length of time since the last defrost operation in said refrigeration compartment;determining the length of time since door to said refrigeration compartment was last opened;determining a compressor time by performing at least one of: determining the length of time a compressor has been operating, wherein said compressor operates to provide refrigeration for the interior of said refrigeration compartment;determining the length of time since said compressor ended operation;calculating an estimated humidity level for the interior of said refrigeration compartment based at least in part on said temperature in the interior of said refrigeration compartment, said length of time since the last defrost operation, the length of time since the door to said refrigeration compartment was last opened, and said compressor time; andactuating said humidifier when said estimated humidity level is less than said predetermined desired humidity level. 2. The method of claim 1 wherein said predetermined humidity level is set by a user. 3. The method of claim 2 wherein said predetermined humidity level is adjustable. 4. The method of claim 1 wherein actuating said humidifier includes operating said humidifier for a calculated amount of time based on the comparison of said estimated humidity level to said predetermined desired humidity level. 5. The method of claim 1 wherein said humidifier is an atomizer. 6. The method of claim 5 wherein said atomizer is ultrasound-based. 7. The method of claim 6 wherein said atomizer is a microfilm ultrasound water atomizer. 8. A control system for actuating a humidifier providing humidification to the interior of a refrigeration compartment, said system including: a humidification setting memory for storing a predetermined desired humidity level for the interior of the refrigeration compartment;a thermometer for measuring the interior temperature of said refrigeration compartment;a defrost timer for measuring the time since last defrost operation in said refrigeration compartmenta door timer for determining the length of time since door to said refrigeration compartment was last opened;a compressor timer determining the length of time a compressor has been operating and determining the length of time since said compressor ended operation, wherein said compressor operates to provide refrigeration for the interior of said refrigeration compartment;a humidity estimator, wherein said humidity estimator calculates an estimated humidity level for the interior of said refrigeration compartment based at least in part on said temperature in the interior of said refrigeration compartment, said length of time since the last defrost operation, the length of time since the door to said refrigeration compartment was last opened, and said compressor time;a humidity comparator, wherein said humidity comparator retrieves said predetermined desired humidity level from said humidification setting memory and compares it to said estimated humidity level, wherein said humidity comparator generates a humidifier actuation command when said estimated humidity level is less than said predetermined desired humidity level; anda humidifier actuator for actuating said humidifier in response to said humidifier actuation command. 9. The system of claim 8 wherein said predetermined humidity level is set by a user. 10. The system of claim 9 wherein said predetermined humidity level is adjustable. 11. The system of claim 8 wherein said humidity comparator also determines an amount of time for said humidifier to be actuated and operating said humidifier for that amount of time. 12. The system of claim 8 wherein said humidifier is an atomizer. 13. The system of claim 12 wherein said atomizer is ultrasound-based. 14. The system of claim 13 wherein said atomizer is a microfilm ultrasound water atomizer. 15. A humidification system providing humidification to the interior of a refrigeration compartment, said system including: a humidifier receiving a humidifier actuation command and providing humidification to the interior of a refrigeration compartment in response to said humidifier actuation command,wherein said humidifier actuation command is determined based on a comparison of a predetermined desired humidity level for the interior of said refrigeration compartment to an estimated humidity level,wherein said estimated humidity level is determined based at least in part on the temperature in the interior of said refrigeration compartment, the length of time since the last defrost operation, the length of time since a door to said refrigeration compartment was last opened, and a compressor time,wherein said compressor time is based on the length of time a compressor has been operating, andthe length of time since said compressor ended operation. 16. The system of claim 15 wherein said predetermined humidity level is set by a user. 17. The system of claim 16 wherein said predetermined humidity level is adjustable. 18. The system of claim 15 wherein said humidifier is an atomizer. 19. The system of claim 18 wherein said atomizer is ultrasound-based. 20. The system of claim 19 wherein said atomizer is a microfilm ultrasound water atomizer.
