Abstract
A method for controlling a thermal regulation circuit of a vehicle. The circuit includes first and second heat exchangers situated in series in a direction in which an air flow is intended to pass through each heat exchanger. The circuit also includes an additional heat exchanger situated upstream of the first heat exchanger with respect to the air flow. The circuit is configured to allow a refrigerant fluid to circulate through the first exchanger and also configured to allow a heat-transfer fluid to circulate through the second exchanger and through the additional exchanger. The method includes generating or increasing a flow rate of the heat transfer fluid in the additional exchanger depending on operating modes of the circuit.
