Heat pump including a closed circuit containing a refrigerant fluid and a lubricant, the closed circuit including a fluid compressor and a return circuit for returning fluid to the compressor, the compressor extending in the closed circuit between a fluid inlet and a fluid outlet, the return circuit extending in the closed circuit between the fluid outlet and the fluid inlet. The return circuit includes a first line extending between the fluid outlet and the condenser, a second line extending between the condenser and the expander, a third line extending between the expander and the evaporator, and a fourth line extending between the evaporator and the fluid inlet. The closed circuit includes a first widening of a line of the return circuit. The fluid includes a mixture of a first Freon, a second Freon and a third Freon, and the lubricant includes a synthetic polyolester oil. |
