Three performance indicators are taken into account: the expander shaft power, the expander isentropic effectiveness, and the cycle efficiency.

The expander isentropic effectiveness is defined by: & =

Mir * (hr, su, exp hr, ex, exp, s)

W - W

And the cycle efficiency by: T]cycie = shexp —

Qevap

A shaft power ranging from 0.38 to 1.82 kW is obtained, corresponding to a mechanical isentropic effectiveness ranging from 43 to 68% and a maximum cycle efficiency of 7.4%. The pressure ratio over the expander varied from 2.7 to 5.4.
