The present invention relates to a device for controlling deodorization and sterilization of a cold warehouse to maintain an optimal product storage state by sterilizing stored food in a cold warehouse through plasma-based radical generation and removing odor generated therefrom. The deodorization and sterilization control device for low temperature warehouses using the radicals of the present invention for achieving the above object is a door sensor and a human body sensor installed inside and outside the door of the low temperature warehouse, and input values and settings of the door sensor and the human body sensor. A controller that outputs a plasma generation control signal that has been processed according to the input value of the value input unit to a driver, a plasma generator that generates plasma by the driver, and wavelengths of light generated by the plasma generator are TiO 2 , Rh, Ag , Ni, Cu, and a radical generator that generates radicals according to the 5-photocatalytic oxidation reaction, and a cyclone generator that collects and filters the radicals generated by the radical generator and then sends them remotely.
