PROBLEM TO BE SOLVED: To provide a method for heat transfer, with which in a method for heat transfer using water as a heat transfer medium, a flow friction resistance is reduced without lowering heat transfer characteristics, the length of a piping capable of transporting the heat transfer medium can be extended without increasing power of a flow transportation pump, the diameter of a piping capable of transporting the heat transfer medium at a fixed flow rate is lessened and the application cost of the piping can be decreased. SOLUTION: This method for heat transfer, having low flow friction resistance is characterized in that an aqueous solution containing an anionic surfactant represented by general formula (1) A-B (A is an aliphatic hydrocarbon group or an aromatic hydrocarbon group or alicyclic hydrocarbon group containing an aliphatic hydrocarbon group in the side chain; B is a hydrophilic group) as the heat transfer medium. |
