Summary
The investigation results of environmentally friendly refrigerant R134a condensation in minichannels with internal diameter d = 0.1 ÷ 3.3 mm was shown. The authors appointed local and average pressure drops in whole range of quality (x = 0 ÷ 1). Influence of quality and mass flux on pressure drop was illustrated. The results of experimental investigations were compared to the results of calculation according to correlations proposed by other authors. The authors got many experimental results in this range, with was the essence to made owns correlation.
