| 摘要 |
This invention relates to refrigerating or air conditioning system comprising at least one exchanger (2, 3). The system uses a refrigerant fluid according to a thermodynamic cycle comprising at least one liquid-vapor expansion phase. According to the invention, the liquid-vapor expansion phase is created by means of a diphasic turbine (4b) that actuates a ventilator (5b), causing air to circulate on said exchanger (3).
