Small Scale Expander for Geothermal.
Small Scale Expander for Geothermal.
(OP)
I am designing a third world heat engine. My team is looking at retrofitting a turbine or possibly a scroll compressor into a scroll expander. Has anyone on here had hands on experience with those retrofits? I can't find a manufacture that sells scroll/screw expanders for the size I need. I would rather purchase one or make one myself then hack one together, reliability is important and this is a time critical project.
Also, I am trying to find a pump that will work with pressurized liquid r134a. Any ideas on that?
Thanks
Colin

R-134 is a Freon right? do not think you want to use it or base a unit on it
