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. |

1. A heat pump comprising:
a closed circuit containing a refrigerant fluid and a lubricant, the closed circuit comprising 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, complimentarily to the compressor, between the fluid outlet and the fluid inlet, the return circuit comprising a condenser, an expander and an evaporator, said return circuit comprising 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, wherein said closed circuit comprises a first widening of a line of the return circuit containing pipes, in that the fluid comprises a mixture of an R32 first Freon (difluoromethane), an R125 second Freon (pentafluoroethane) and an R134a third Freon (1,1,1,2-tetrafluoroethane), and in that the lubricant comprises a synthetic polyolester oil. |
