Abstract The seawater source heat pump (SWHP) has attracted significant attention as a renewable energy utilization system. The beach well infiltration intake system (BWIS) effectively improves the stability, reliability, and energy-efficiency of SWHP systems in cold climate areas. A seepage and heat transfer model is established for scientific BWIS applications. MATLAB is used to analyze solutions for the seepage model, as well as to obtain a numerical solution for the heat transfer model. The analytical solution for the seepage model is a fast-solving method compared with the numerical solution. The method explicitly analyzes the qualitative and quantitative relationships among influencing factors of the system. In the heat transfer model, the advection term dominates the heat transfer, while the conduction term can be ignored. A BWIS for SWHP systems is tested and the simulation results agree with the measured data. The simulation model is used to analyze BWIS performance. All system influencing factors are identified and classed according the model. The results demonstrate the usefulness of the simulation model, thereby validating the method as a potential engineering tool for BWIS design.
