Summary

In the paper, results of an experimental research on heat exchange are presented at condensation of coolant R-407C inside a smooth horizontal pipe. For change of regime parameters of process: heat transfer from 2000 to 19 000 W/m2, temperature of saturation vapour from 26.1 to 40.1°C and speeds of vapour from 0.013 to 0.26 m/s average on perimeter of cross-section section, the heat transfer coefficient has a constant value of 1250 W/(m2K).
