Analysis of Cooling Systems for Offshore Wind Power Booster Station Based on AHP-CRITIC

In this study, three types of cooling systems—varied refrigerant volume (VRV) cooling system, fan coil cooling system with seawater as a cold source, and radiant cooling system with seawater as a cold source—were designed for the electronic equipment cabin of an offshore wind power booster station. We developed an evaluation system to study these three cooling systems from three aspects, namely economy, installation, and energy savings. We assigned the weights of important factors, such as equipment cost, manual installation cost, and operation and maintenance cost, in the analytic hierarchy process–criteria importance through inter-criteria correlation (AHP-CRITIC). Scores of 74.1, 78.3, and 81.4 were obtained for the VRV cooling system, fan coil cooling system with seawater as a cold source, and radiant cooling system with seawater as a cold source, respectively. These findings indicate that the AHP-CRITIC method can be successfully applied to the selection of cooling systems for offshore wind power booster stations. The proposed evaluation method is expected to contribute to the practical application and selection of other cooling systems.
