ABSTRACT

The results of an experimental study of heat transfer of R134a refrigerant flow in tubular channels with twisted tape inserts are considered. The flow regime implemented under these conditions is shown. A criterial dependence generalizing experimental data on heat transfer of a boiling refrigerant is presented.
