Abstract
The method comprises an initial cooling step (E0) during which the temperature (T_ECH) of the heat exchanger (30) is lowered and, at the same time, the flow rate of the said first flow (FLS) is set to an initial flow rate. Following the initial cooling step (E0), an operation of circulating the first flow (FLS) is initiated (E1) and during this the said first flow (FLS) passes through a heat exchange (30) at a first flow rate which is higher than the initial flow rate. The initial flow rate of the first flow may be set to zero or to a value set so that the pressure inside the said circuit is greater than or equal to the pressure outside the said circuit.
