Abstract
A refrigerated unit is well suited for storing fruits and vegetables. A household-sized refrigerated unit includes a storage space for retaining fruits and vegetables. The temperature within the storage space is controllable within a range of approximately 40-65 degrees Fahrenheit. The humidity level within the storage space is regulated to prevent unnecessary desiccation of the fruit and vegetables, and to prevent excessive condensation. The unit is provided with a mechanism for regulating the level of ethylene gas within the storage space to either retard or accelerate ripening, as desired.
