Deep Vacuum Condensers below 3 mbarA
Deep Vacuum Condensers below 3 mbarA
(OP)
On my heat exchanger program it issues a warning and wont calculate below 3mbarA - it states too low. I'm looking to evaluate the feasibility of running a system with deep vacuum at 2 mbarA. And wish to re-design my condenser.
SO.. How is it possible ? and what are the limits of HX design programs ? HTFS limits to 3 mbar.

Practically speaking there isn't much difference.
What is the fluid on the low pressure side?
Do you have good thermodynamic data at these pressures/temperatures?

As stated by Ed Stainless, a lot depends on the fluid you are trying to condense. If you are trying to condsnse steam, say from an ejector system, 3 mb steam is saturated well below the freezing temperature.

If the thermodynamics was measured at suitable temperature conditions can one therefore assume they are valid ? my data records not really say about pressure limits?
