Summary

The thermal and fluid dynamic characteristics of an air-to-air R134a refrigerant charged two-phased closed thermosyphon heat exchanger were determined. The evaporation and condensation heat transfer coefficients and the pressure drop across the heat exchanger were determined. The basic heat transfer theory is given and experimentally determined correlations are presented. These correlations were shown to be reasonably accurate and it was thus concluded that they can be reliably applied when designing and rating air-to-air thermosyphon heat exchangers.
