Abstract

The invention proposes a pressure-reducing module for an air conditioning circuit (10) 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 (120), and a distribution valve (16) 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 (131, 132) 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 (131, 132) via its outlets.
