Abstract (en)
[origin: EP2514933A1] The method involves supplying working medium i.e. fluorinated hydrocarbon, from a feed pump (50) to a lubricant separator (10), and separating portion of lubricant from the medium. The separated portion is supplied from the separator to an expansion machine (30). The medium is supplied from the separator to an evaporator (20) for evaporating the medium, and the evaporated medium is supplied to the machine. The medium is supplied from the machine to a condenser (60), and the medium is liquefied with the condenser, where the liquefied medium is supplied from the condenser to the pump. An independent claim is also included for a thermodynamic cyclic process device comprising an expansion machine.
