I'm working on a project right now to create a human powered (hand/pedal powered) miniature refrigeration system running on the vapor-compression cycle. We have already built a "proof of concept" version that uses an A/C compressor that we ripped out of a car in a junkyard! Now, we are moving to the prototyping phase, and we have reached a large hiccup. It's surprisingly difficult to find a small open drive refrigeration compressor, and I was wondering if anyone here had any leads on where one could be found.
Some details for ya:
Our refrigeration system will only need in the neighborhood of 15 W of cooling.
We are working under the assumption that a human can provide around 40 W of input power.
The compressor needs to be small: at least half as small as a car's A/C compressor.
The compressor needs to be open type: mechanically driven (gears or belt- not electric like a household refrigerator).
The compressor needs to handle a pressure ratio of at least 1:5.
Thanks!
