The invention relates to a method for operating a system with a heat transfer fluid, the branched siloxanes of the general formula I. (R 3 SiO 1/2 ) w (R 2 SiO 2/2 ) x (RSiO 3/2 ) y (SiO 4/2 ) z , (I) in the w, x, y and z are each integer values from 0 to 30, w + x + y + z values from 4 to 100, w + y + z> 5x, R is methyl, includes. |
