Abstract (en)

[origin: FR2815397A1] The expansion device (4) of the refrigerating fluid loop is controlled to set the internal heat exchanger efficiency (nu), represented by the equation: nu=(Tec Tse)/(Tsr Tse), where Tec, Tse and Tsr are respectively, temperatures at the compressor input (1), and at the evaporator output (5) and at the fluid cooler output (2), at a reference value such that the fluid leaves the evaporator in a completely gaseous state without overheating.
