Abstract
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).
Claims19
System comprising at least one exchanger-evaporator comprising an evaporator;
- the system using a cooling fluid circulating in a circuit following a thermodynamic cycle comprising at least one liquid-vapor expansion phase;
- the system being characterized in that the liquid-vapor expansion phase is achieved using a two-phase turbine operating as a pressure reducer, activating a fan driving air circulation over the exchanger-evaporator;
- the two-phase turbine being located on the part of the circuit in which the cooling fluid liquid phase circulates.
Process for production of cold or heat using a cooling fluid, circulating in a cooling circuit comprising a condenser according to a thermodynamic cycle comprising at least a liquid-vapor expansion phase, the characteristic step consisting of performing the liquid-vapor expansion using a two-phase turbine activating a fan driving an air circulation over an air exchanger—evaporator;
- the two-phase turbine being located in the part of the circuit in which the liquid phase of the cooling fluid outlet from the condenser circulates.
