Can a Car Airconditioning Compressor be Used as a Pico Steam Turbine?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of using a car air conditioning compressor as a pico steam turbine. Participants explore the potential of repurposing the compressor in a solar thermal application, specifically in conjunction with an induction motor to generate power.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant, Solomon, inquires about the possibility of using a car air conditioning compressor as a pico steam turbine and seeks information and suggestions.
  • Another participant requests clarification on what is meant by a pico steam turbine and expresses curiosity about how a compressor could function as a steam turbine.
  • A participant clarifies that they are referring to a pico/micro/mini turbine setup, intending to use the compressor with an induction motor as a turbine and generator combination.
  • One participant asserts that a compressor is not a reversible machine and is not designed to operate as a turbine.
  • A participant shares their own related project involving a satellite dish to focus sunlight for heating and mentions the need for a boiler and turbine/compressor, suggesting that a scroll compressor might be modified to work as an expander.
  • This participant also discusses their limitations regarding heat input based on solar flux and expresses a goal of generating power during sunny days.

Areas of Agreement / Disagreement

Participants express differing views on the viability of using a compressor as a turbine, with some questioning its functionality while others explore potential modifications and applications. The discussion remains unresolved regarding the practical implementation of such a setup.

Contextual Notes

There are limitations regarding the assumptions about the compressor's functionality and the specific modifications required to adapt it for use as a turbine. The discussion also depends on the definitions of pico steam turbines and the technical specifications of the components involved.

Hi All,
I am a solar thermal enthusiast seeking to try out a few things. I need some info on using car aircondition compressor as a pico steam turbine if it is possible. Links, suggestions and opinions are welcome.

Regards,
Solomon.

what u mean with a pico steam turbine?-make it a little more clear please
and i wonder how a compressor could work as a steam turbine?
 
yes, a pico / micro /mini turbine. Seeking to use the compressor + induction motor combination as a turbine + induction generator.
 
A compressor is not a reversible machine. It is not peformed to act as a turbine.
 
obibask, i have been thinking about a similar setup check out this page for some ideas http://www.redrok.com/engine.htm. I have a large sattelite dish that I will cover with polished aluminum to focus sunlight and generate heat. I still need my "boiler" and turbine/comprssor, I will select an induction motor based on these.

Clausius though i am not familar with a scroll compressor I have heard that they can be run as an expander with some modification.

I will be limited to a maximum heat input of ~4000W with my sattelite dish based on 800W/m^2 solar flux and .8 emisivity for polished aluminum. It would be neat if I could generate a solid 2kW during sunny days.
