Abstract
Experimental research on performance of the plate type condenser is presented in case of using the heat pump system. HFC134a is used as working fluid. The plate number of this plate type condenser is 28 plates and the total heat transfer area is 2.66m^2. Heat transfer coefficient of cold water side and condensation are obtained for the region of saturation in heat transfer area of the plate. The overall heat transfer coefficient of plate type condenser is about 2250〜3300(W/m^2K) when the velocity of the cold water is 0.18〜0.41m/s. The empirical correlation are proposed for predicting heat transfer coefficients of the average condensation and cold water side and composed with the result of the commercial plate the condenser.
