Closed refrigeration display cabinet control method and device and closed refrigeration display cabinet

The invention relates to a closed refrigeration display cabinet control method and device and a closed refrigeration display cabinet, and belongs to the technical field of closed refrigeration display cabinets.The method comprises the steps: obtaining the opening and closing state of each cabinet door of the closed refrigeration display cabinet; when part of the cabinet doors are in the open state, controlling evaporation fans corresponding to the cabinet doors in the open state to be closed, controlling evaporation fans corresponding to the cabinet doors in the closed state to operate at a reduced speed, and controlling operation of a compressor of the closed refrigeration display cabinet based on the detected temperature in the closed refrigeration display cabinet. By means of the method and device, the disturbance capacity of cold air flow at the outlet can be effectively weakened, heat entering the closed refrigeration display cabinet is reduced, and therefore the non-uniformity of cold distribution in th
