The performance tests of a plate type condenser for ocean thermal energy conversion (OTEC) plants are carried out under conditions of OTEC. The total plates used in the condenser are 168 in number and the total surface area is 40.7 m2. The dimensions of plate used in this condenser are 1450 mm in length, 235 mm in width and 1.0 mm in thickness. Freon 22 is used as working fluid. The overall heat transfer coefficient is about 2500W/(m2K) at the cold water velocity of 1 m/s and the vapor inlet temperature of 22.8~23.2°C. The empirical correlations are proporsed for predicting the average condensation heat transfer coefficients and water side heat transfer coefficients for a plate type condenser. The water side pressure drop is 1 m at the cold water velocity of 1 m/s. The water side friction factor is about 0.25 at Reynolds number of 4×103.
