Abstract
The invention proposes a pressure-reducing module for an air conditioning circuit () through which a supercritical refrigerant flows. The module is connected to the circuit via one inlet and two outlets. The module comprises a pressure-reducing device (), and a distribution valve () connected to the pressure-reducing device and to the two outlets. A dual evaporator circuit using such a pressure-reducing module is also proposed. The two evaporators () are mounted in parallel. The module receives the fluid coming from a gas cooler via its inlet and delivers the fluid to at least one of the two evaporators () via its outlets.
