Abstract

A heat transmission method using a heat pump system according to the present invention uses a heat transmission medium containing at least one compound represented by general formula (1). In the formula, Ris a CHFgroup, m is an integer of 0 or more and 3 or less, R, Rand Rare each independently a fluorine atom, a chlorine atom, a bromine atom, an iodine atom or a hydrogen atom, and at least one fluorine atom is contained in a molecule. The heat transmission method includes (A) step of gasifying the heat transmission medium; (B) step of compressing the heat transmission medium into a supercritical state; (C) step of causing heat exchange between the heat transmission medium in the supercritical state and a medium to be heated; and (D) step of decreasing the pressure of the heat transmission medium.
