Global environmental problems such as global warming and the effect of acid rain are becoming more and more serious in the years to come. One of methodologies for solving this problem is to use harmless energy resources. Ocean energy is also one of such energy resources. From such a viewpoint, we are conducting study on OC-OTEC system, which is one of ocean thermal energy conversion technologies. In this system, steam driving a turbine is generated in an evaporater and condenses in a condneser after going throrgh a turbine. However, Steam evaporating rate in an evaporator is affect-ed by fluctuation of surface sea water temperature and ambient pressure. Therefore, it is necessary to define dynamic characteristics of evaporator to gain constant power output. In this paper, we analyzed how evaporation rate is affect-ed when surface sea water temperature and ambient pressure change, and we make clear that dynamic characteristics of evaporator is affected by fluctuation of ambient pressure than that of surface sea water temperature.
