Deep sea water, which is abbreviated as DSW, is defined as the seawater in the depth where photosynthesis does not occur. DSW is characterized by its cleanness, nutritiousness and low temperature in small variations in all seasons. Rationalization of DSW utilization provides possibilities of DSW business expansion, moreover energy saving. Since the low-temperature stability of DSW produces large economical merits, the development of the efficient energy utilization system is required. This project to investigate the system has been described focusing on the power plant condenser. By utilizing DSW as the cooling water in the plant circulation systems, the temperature at which heat is rejected from the cycle becomes lower. Therefore, improvement in thermal efficiency is anticipated. Since DSW prevents sea living things, such as shellfish, from clinging to each component of the system by its cleanness, easy maintenance and curtailment of auxiliary facilities are anticipated. Besides, DSW is considered as raw materials of pure water manufactures.
