Here is a simplified description of the system, which should clarify the need for a very low temperature compressor.
The system is for a liqN2 powered engine with vaporization of the liqN2 in an economizer by a secondary gas(N2 or air). The compressor is to pressurize the cooled secondary gas...
David,
1. compression is from 1 atm. to 4 atm, Outlet of -92 C is acceptable.
2. oil should be tolerable downstream but probably not good to discharge to atmosphere.
3. not sure what you mean by compression volume. Volume flow is about 6 cfm at outlet conditions.
Thanks for your help,
Steve...
Thanks muleshoe.
The system is for a liqN2 powered engine with vaporization of the liqN2 by a secondary gas(N2 or air).
The compressor is to pressurize the cooled secondary gas from 1 atm. to 4 atm., thus economizing the liqN2 and using minimal compression work.
Hope this makes sense
I have searched the web to no avail to locate a small
(1 to 2 hp) compressor for compressing nitrogen at -150 C(-240F) with a compression ratio of about 4.
I would appreciate any information on compressor design limitations at very low temperatures.
Thanks for your help
Thanks cryotechnic,
I e-mailed Rix . They can provide a compressor to handle only -100F.They did not say anything about specials, or if - 240 F is even possible.
I am trying to design a system with minimal compression work while economizing the liq N2.
I will e-mail a few more suppliers...
