Design calculator for Condensers, evaporators, heat pumps

AI Thread Summary
A discussion on finding effective design calculators for condensers, evaporators, and heat pumps highlights several options. Users recommend a calculator from RAE Corp, which is available under their "downloads" section, but note that it requires a password for access. Carrier also offers a reliable calculator, though a sales engineer must be contacted for a trial version. Another user mentions discovering a program called Evap-Cond, which they plan to test against proven designs. Overall, the conversation emphasizes the importance of reliable tools for HVAC design calculations.

Hey guys

Anyone knows a good calculator for condenser, evaporator, or heat pump design? common unknown parameters would be number of passes, or length of columns, depth or rows...

Thnks
 
Engineering news on Phys.org
These guys have one that works pretty well (under "downloads" it's the "total package" : https://www.rae-corp.com

Carrier makes one that is pretty good as well, though you'll have to contact a sales engineer/rep for a trial version.

thnx man

very helpfull
 
i just finished downloading the package from rae-corp. they are asking for a password ! damn
 
Hmm... It has been a while since I used it and I guess I forgot about that... Sorry. Depending on your situation, though, they may be inclined to give you one.
 
ahh..thnx
besides today i found another program something called evap-cond. i just have to test it with proven designs. definitely not going to test it on CFD software :)
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
