Summary

An experimental study is reported on the boiling heat transfer of R134a, R22, R114 and R12 flowing inside a 7.9 mm inside diameter horizontal smooth tube. Using a water-heated, double-tube type evaporator, the local heat transfer coefficients are measured for both counter and parallel flows. The proposed correlation shows that the nucleate boiling is not fully suppressed even in the high-quality region in the case of counter flow, while convective evaporation is dominant in the high-quality region with uniform heat flux condition.
