[Equest-users] How to model a compressor

[Joe Fleming]

Hi Mike,

 

Not sure if someone already responded for you, but for R744/CO2 you can use
the standard DX performance curves that are internal to eQuest, or you can
create your own.

 

To create your own custom curves (for performance and/or capacity) you will
need to obtain performance data for the R744 compressors at various
operating conditions .  You can input data points using one of several
functions eQuest has available.

See image below on where to navigate and experiment.  Also, search this
site:  http://lists.onebuilding.org/pipermail/equest-users-onebuilding.org/
for performance curve discussions.

 

  

 

Good luck and let us know if you need further assistance!

Hi All,

What is the best way to model a compressor in equest.

Equest has several compressors to chose from, but I'm trying to create one
that runs on CO2 refrigerant.

Thanks a billion,

Mike
