The embodiment of the invention discloses a ventilation and fresh-keeping control system for a marine dry grain depot, which is used for performing ventilation and fresh keeping on the marine dry grain depot, and comprises a combined air-conditioning unit used for correspondingly processing external fresh air and return air of the dry grain depot and then sending the processed air back to the marine dry grain depot, return air of the dry grain depot flows back to the combined air conditioner unit through an air return pipe, a first temperature sensor is arranged on the air return pipe, and a first-stage refrigerating coil, a second temperature sensor, a second-stage refrigerating coil, a water baffle and a heating coil are sequentially arranged between a mixing box and an air feeder of the combined air conditioner unit. And the electric control box is in signal connection with the first temperature sensor and the second temperature sensor and is used for controlling the first-stage refrigerating coil pipe, the second-stage refrigerating coil pipe and the heating coil pipe to work. The air temperature distribution in the dry grain depot can be effectively improved, and the preservation time of articles in the depot is prolonged.
