The invention relates to a water temperature consumption acquisition method and device, equipment and a medium. The method comprises the following steps: acquiring an available cooling data sequence of water; detecting the available cooling data sequence by adopting a density-based anomaly detection algorithm to obtain abnormal cooling data in the available cooling data sequence; removing the abnormal cooling data from the available cooling data sequence to obtain a normal cooling sequence of the water; and counting the normal cooling sequence according to a preset duration to obtain a total temperature consumption amount in each duration, wherein the available cooling data sequence is used for representing time-based density distribution of the temperature drop amount of the water. Through adoption of the method, the accuracy of the determined total temperature consumption can be greatly improved.
