To address the problems of the high energy consumption and the heavy pollution of the air-conditioning system in marine ships,a numerical model of regenerative indirect evaporative cooler(RIEC)for heat and mass transfer using seawater as the natural cooling media is established.The influence of five environmental parameters and two structural parameters on the primary air outlet temperature and the wet bulb efficiency is analyzed,and compared with a pure water RIEC.The results show that under the same geometric and working conditions,the cooling performance of the seawater RIEC slightly decreases compared with that of the pure water RIEC,the primary air outlet temperature on average increases by about 0.28 ℃,and the wet bulb efficiency on average decreases by about 6.73％.Therefore,from the perspective of thermal performance,the application of the seawater RIEC in ship air-conditioning is feasible.
