HEAT TRANSMISSION METHOD AND HIGH-TEMPERATURE HEAT PUMP DEVICE |
| 摘要 |
A heat transmission method using a high-temperature heat pump system accommodating a heat transmission composition includes the step of evaporating the heat transmission composition, the step of compressing the heat transmission composition, the step of condensing the heat transmission composition, and the step of decreasing the pressure of the heat transmission composition at a temperature of 70° C. or higher, which are performed sequentially. The heat transmission composition contains cis-1,3,3,3-tetrafluoropropene at a mass ratio of 95.0% by mass or more and 99.9% by mass or less, and contains trans-1,3,3,3-tetrafluoropropene or 2,3,3,3-tetrafluoropropene at a mass ratio of 0.1% by mass or more and 5.0% by mass or less; and the heat transmission composition has a condensation temperature of 70° C. or higher. |

1. A heat transmission method using a high-temperature heat pump system accommodating a heat transmission composition, the heat transmission method including the step of gasifying the heat transmission composition, the step of compressing the heat transmission composition, the step of condensing the heat transmission composition, and the step of decreasing the pressure of the heat transmission composition, the steps are performed sequentially;
wherein the heat transmission composition contains cis-1,3,3,3-tetrafluoropropene at a mass ratio of 95.0% by mass or more and 99.9% by mass or less, and contains trans-1,3,3,3-tetrafluoropropene or 2,3,3,3-tetrafluoropropene at a mass ratio of 0.1% by mass or more and 5.0% by mass or less; and the heat transmission composition has a condensation temperature of 70° C. or higher. |
