Coolant fluid circuit comprising a compressor (1), a condenser (2), a pressure reducer (3) and an evaporator (4). According to the invention, a heat exchanger (9) is provided in order to transfer heat from the conduit (6) arriving at the pressure reducer to the conduit (8) arriving at the compressor, so as to condense the residual vapour and/or to vaporise the residual liquid which may respectively be found in these conduits. The fluid reaching the pressure reducer and that reaching the compressor are thus practically free of vapour phase and liquid phase, respectively, which improves the operation of the device. Application to air conditioning of the passenger compartment of motor vehicles. <IMAGE> |
