Abstract
The purpose of this study is to know the effects of mass flow rate, inlet temperature and type of flow against overall heat transfer coefficient (U). Heat Exchanger used in this study was plate and frame type of CARBAMATE CONDENSER. Mass flow rate of hot fluida was variated into 4055857,171 and 5075536,533 kg/s; mass flow rate of cold fluida was variated into 0.276 and 0.22 kg/s; inlet temperature of hot fluida was variated into 142,4oC; type of flow was variated into counter current. The results showed that mas flow rate of hot and cld fluid influenced overall heat transfer coefficient. Also, the higher inlet temperature, the bigger overall heat transfer coefficient obtained. In this study, the biggest of U value was obtained in variable of inlet temperature 187,6oC, mass flow rate of cold fluid 0,276 kg/s, mass flow rate of hot fluid 0,3 kg/s, which were 140.6532 W/m2oC using type of counter-current flow and 135.4576 W/m20C using type of co-current flow. Type of counter-current flow gave more satisfactory result of U value than type of co-current.
Keywords: plate and frame, heat transfer, heat exchanger, overall heat transfer coefficient.
