A non-cyclic hydrocarbon having at least five hydrocarbons, used at -150 to +120[deg]C is used as a heat carrier. Preferred Features: The heat carrier is 3-methylpentane, 2-methylpentane, 1, 5-hexadiene or 1-hexene. The carrier is used at a pressure of 1-5, preferably 1.5-3.5 bar and at temperatures of -150 to -100[deg]C. |
