Interesting little design question.
Say I have a bottle of refrigerant (closed) and I put a thermal input to it. Will the pressure rise and thus the boiling point rise as the liquid evaporates?
Flipside of that as it cools, the condensing pressure will drop as the bottle is cooled?
I have a...
We are looking at building or retrofitting a turbine for use with r134a. I can't find a book or reference material to correctly design the turbine to operate at low rpm and under given operating parameters. Heat is not a problem in our case but packaging is. We need torque over power. Any...
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...
I need a pump that can pump pressurized liquid R134a or equivalent with a a low possibility of a two phase mixture around a closed loop. The pressure on the inlet side may be as high as 50 psi and the outlet may need to be as high as 200 psi. I need a flow rate of around 1 gpm. Bigger is better...
