A method for improving the thermodynamic performance of a heat pump, the pump comprising a closed fluid circuit, the fluid circuit comprising a compressor (1), a condenser (2), an expander (3), an evaporator (4), a first pipe and a compressor return pipe, the compressor, the condenser, the expander, the evaporator, the first pipe and the return pipe being disposed in series in the fluid circuit, the first pipe connecting the compressor to the condenser, the return pipe comprising a second pipe linking the condenser to the expander, a third pipe connecting the expander to the evaporator and a fourth pipe connecting the evaporator to the compressor, the first pipe comprising a first pipe bulge (5), said first bulge (5) extending, on the first pipe, between a first end and a second end, said first bulge (5) containing internal tubes (50), said internal tubes (50) being disposed in parallel in the fluid circuit, the method comprising a step consisting of transporting a mixture of a refrigerant fluid and a lubricant miscible with the fluid, in the fluid circuit, without an increase in the temperature of the mixture between said first end and said second end. |
