Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.
The recirculation of liquid from the liquid reservoir to the condenser inlet is being proposed as a new method to reduce and control the condensing pressure in compression refrigeration systems. In this work the condensation process of different refrigerants with liquid recirculation in an air cooled condenser has been analyzed. The analysis is based on a mathematical model implemented in a computer program. The influence of the liquid recirculation ratio on the condensing pressure (condensing temperature) has been studied. Results of the operating conditions established in the condenser for different liquid recirculation ratios, such as, heat transfer coefficients, heat transfer rate, pressure drop, etc are shown and discussed in the paper.
