This utility model discloses a combined wet and dry indirect cooling tower, belonging to the field of cooling tower technology. Specifically, it relates to a combined wet and dry indirect cooling tower, including: a tower body, a baffle assembly, a fan, a water tank, a water collector, spray heads, a first heat exchange assembly, water distribution packing, and a second heat exchange assembly. This utility model can provide two cooling methods depending on the seasonal temperature. In summer, the first baffle is closed and the second baffle is opened, which can reduce the amount of wet-bulb air entering the coil and the indirect heat exchanger, thereby improving heat exchange and lowering the outlet water temperature. In winter and spring, the second baffle is closed and the first baffle is opened, so that the water and air do not come into contact, there is no evaporation, and water consumption is greatly reduced. Thus, this utility model can improve the applicability and practicality of the cooling tower, thereby solving problems such as high approach temperature, high water consumption, and white mist in cooling towers.

The application discloses an artificial cooling equipment parameter automatic optimization method and system based on soil data analysis, and relates to the technical field of artificial cooling. The method comprises the following steps: building a regional soil cooling simulation space according to three-dimensional soil structure information, water injection well distribution information and extraction well distribution information; obtaining three-dimensional soil temperature distribution through distributed optical fiber temperature measurement equipment monitoring, and calculating three-dimensional soil temperature difference distribution in combination with a preset cooling target; constructing a regional soil cooling prediction model based on a soil flow mechanism and the regional soil cooling simulation space; using the regional soil cooling prediction model to perform iterative optimization of cooling equipment parameters, and outputting adaptive equipment parameters; and controlling the cooling device and the heat energy recovery device to perform soil cooling work in a target region according to the adaptive equipment parameters. The technical problems of low cooling efficiency, excessive resource consumption and local hot area residue caused by the fact that the artificial cooling equipment parameters cannot be dynamically changed and optimized in real time according to soil data in the prior art are solved.
