Abstract

A single tube condenser test facility capable of measuring heat transfer coefficient of condensing refrigerants in horizontal tube has been built and implemented at the Air Conditionning and Refrigeration Center at the University of lllinois. Baseline testing with CFC-12 and preliminary testing with HFC-134a has been done. For CFC-12 the experimental data was within ± 20% of the Shah correlation, ±27% of the Traviss correlation and ±25% of the CavaIlini-Zecchin correlation. Due to its higher liquid thermal conductivity the heat transfer coefficient for HFC-134a was higher than that of CFC-12 by as much as 22%.
