Résumé

An experimental study is performed to investigate condensation of superheated R134a inside a vertical tube. Experimental tests have been performed at the normal operating conditions found in a small power vapour compression refrigeration system. The experimental setup is described and the experimental procedure and data reduction method are explained. Experimental results of the condensation heat transfer coefficient are reported and discussed for different pressures, vapor mass flow rates and vapor degrees of superheating. The experimental heat transfer coefficients are also compared with those obtained using different correlations; it is found that the values are well predicted with the Chen correlation.
