AI Technical Summary
Existing cooling water systems are ill-suited to the complex and variable operating conditions of ship condensers, leading to unstable condenser vacuum levels, which affects main engine efficiency. Furthermore, the lack of accurate methods for calculating cooling water flow and resistance results in redundant or insufficient system design.
A multi-parameter iterative calculation model is established. By real-time monitoring and database retrieval of physical property parameters, a model of the total heat load of the condenser and the cooling water flow rate is constructed. Combined with iterative algorithms, the cooling water flow rate and resistance are optimized to achieve adaptive adjustment of operating conditions.
It achieves constant condenser vacuum, improves main unit operating efficiency, optimizes cooling system design, reduces energy consumption, and improves adjustment accuracy and response speed.
