Research on Sensible Heat Treatment Methods for Marine Desiccant Evaporative-cooling Air-conditioning System

研究船用除湿蒸发冷却空调系统的显热处理方式,以降低系统的除湿降温要求。通过对各种冷源及其利用方式的组合,构建多个显热处理方案,计算分析各个方案处理显热的效果。结果表明,采用海水冷却器、室内排风为二次风的间接蒸发冷却器,结合直接蒸发冷却器的显热处理方案能取得最佳的显热处理效果。

The methods of sensible heat treatment for marine desiccant evaporative-cooling air-conditioning system are studied to reduce system＇s dehumidification requirements. Through the optimal combination of possible cooling sources and their possible utilization ways, some sensible heat treatment programs are developed, and their effect of sensible heat treatment are analyzed. The results show that the heat treatment program using sea water cooler, indirect evaporative cooler with indoor exhaust air as secondary air and direct evaporative cooler can achieve the best heat treatment effect.
