Document Type and Number:
Japanese Patent JP2949228
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for heat exchanging by reducing a frictional resistance at a part except a heat exchanger of a pipeline decreasing an energy required for transporting a heat medium and avoiding a decrease in the heat transfer rate at the exchanger at the same time. SOLUTION: In the method for heat exchanging in a heat exchanger 1X of a pipeline 1 by transporting a heating medium via the pipeline 1; a surfactant is added to the medium, a Reynolds number area for converging a frictional resistance increasing as the number is increased at the exchanger 1X is selected, a Reynolds number area except the above area in a part 1Y except the exchanger is selected, and the resistance and the heat transfer rate of the exchanger 1X are set larger than those of the part 1Y except the exchanger.
