Abstract (en)

[origin: WO2019145550A1] The invention relates to a heat-exchange circuit (1) comprising: a circuit of pipes (2) through which a liquid (8) circulates for transporting calories for temperature control; and a degassing vessel (3) connected to the circuit of pipes (2) and designed to reserve an expansion volume in which said liquid is surmounted by a volume of gas (9). The degassing vessel (3) is advantageously provided with a heating element (5, 6), said heating element being positioned so as to remain outside the liquid (8) in the planned conditions of use and being designed so as to allow the gas (9) surmounting the liquid (8) to be heated directly.
