The performance characteristics of a small-size screw expander for energy conversion of hot springs are described in this report. Instead of lubrication oil, the test machine is fed high temperature oily working medium liquid for the lubricant. This idea is proposed in order to omit lubrication of pump. By feeding of the oily working medium liquid lubricant, the working fluids must be of low quality(dryness fraction). For the calculation of the wet expantion, we introduce the actual adiabatic expansion with thermophysical properties of the actual working medium. This expansion is the isentropic expansion in which the adiabatic exponent K is variable. The calculated values of this method gives fairly good agreement with the experimental results. In this paper, as the result of the calculation and experimentation, we report the performance characteristics of a small-size screw expander operated with a low (x = 0.6～1.0) quality actual working medium.
