This invention relates to the field of air conditioning and refrigeration room control technology, and more particularly to a high-efficiency intelligent control method for air conditioning and refrigeration rooms based on a DDC module. This invention analyzes the cooling and heat dissipation trends of the monitored air conditioning and refrigeration room using environmental parameters to determine if there is a risk of insufficient heat dissipation margin. It performs time-series coupling analysis on each monitoring optical path to mark characteristic monitoring optical paths. Based on the transmitted light intensity parameters of each characteristic monitoring optical path, it constructs several optical path fluctuation curves to determine the deficiency tendency category of the monitored air conditioning and refrigeration room. Based on the deficiency tendency category, it determines the cooling optimization adjustment method for the monitored air conditioning and refrigeration room. This invention enables rapid identification of whether there is a risk of insufficient heat dissipation in the monitored air conditioning and refrigeration room, and adaptively adjusts the cooling optimization method according to the actual situation of the monitored air conditioning and refrigeration room, improving the reliability of intelligent control of the air conditioning and refrigeration room.
