AI Technical Summary
⚠Technical Problem
Existing storage facilities face issues with the freeze-drying phenomenon, where temperature differences during defrosting operations cause moisture evaporation from stored items, leading to deterioration, and existing solutions do not adequately manage warm air influx post-defrosting.
⚗Method used
A storage facility with a control device that manages compressor and blower rotation speeds post-defrosting, gradually increasing them based on outside air temperature and heat load to minimize temperature differences and reduce moisture evaporation.
🎯Benefits of technology
The solution effectively suppresses item deterioration by gradually adjusting compressor and blower speeds, reducing temperature disparities and maintaining stable storage conditions post-defrosting.

Abstract
This storehouse comprises: a body that includes a storage chamber and a cooler chamber; a door that is provided in the front surface of the storage chamber; a cooler that is disposed in the cooler chamber and generates cold air by exchanging heat with a refrigerant; a blower that feeds cold air to the storage chamber; a compressor that feeds the refrigerant to the cooler; an internal temperature sensor that measures the internal temperature, which is the temperature in the storage chamber; and a control device that controls the compressor and the blower. The control device stops the compressor and the blower, and executes a defrosting operation for defrosting the cooler as well as a first post-defrost operation that is a cooling operation for after the defrosting operation has been completed. In the first post-defrost operation, the control device determines an initial setting rank on the basis of the outside air temperature and a rank indicating the heat load quantity in the storage chamber, activates at least one of the compressor and the blower at the rotation speed set for the initial setting rank, increases the setting rank every time a preset rank-increase period elapses, and gradually increases the rotation speed of at least one of the compressor and the blower.
