Abstract (en)
[origin: EP0176149A2] A turbine (6) arranged in the refrigeration circuit of a refrigerator so as to be driven by refrigerant fluid is connected into the circuit at a position such that the enthalpy of the refrigerant fluid driving the turbine is substantially at a maximum. The turbine (6) comprises a rotor (11) which is driven by means of injected refrigerant fluid. The turbine (6) drives a fan impeller (16) which is preferably coupled to the turbine (11) rotor by a magnetic coupling.
