Thermoregulation device and method, in particular for a motor vehicle

Abstract

The invention relates to a thermoregulation device comprising a refrigerant circuit (1) which is configured to perform a thermodynamic cycle, the circuit (1) comprising an ejector (22), a first heat exchanger (12), an accumulator (24) and a second heat exchanger (14), the ejector (22) having a primary inlet (22a), a secondary inlet (22b) and an outlet (22c) for the refrigerant, the first heat exchanger (12) being intended for exchanging heat with a first fluid to be thermoregulated, the second exchanger (14) being intended for exchanging heat with another fluid to be thermoregulated, the device being configured so that the refrigerant circulates, in a first loop, between the outlet (22c) and the secondary inlet (22b) of the ejector (22), passing successively in series into the first exchanger (12), the accumulator (24) and the second exchanger (14), an inlet of the second exchanger (14) being connected to a first outlet (24b) of the accumulator (24), which is capable of delivering the refrigerant in liquid phase.
