[Bldg-sim] eQuest VRF Modeling

[Carol Gardner]

Hi Chris,

Yes it is possible to do. I am just finishing a peer review of a project
that uses one. There has been a lot of discussion about the BSUG
presentation by Dana Troy that you will find in the archives. There is also
a lot of information available from the manufacturers - Mitsubishi and
Daikin - so you can create and enter curve data that reflects the actual
heat pump you are trying to model. Creating curves is not difficult but it
is pretty time consuming. If you are moving heat/cool around the building
then there is post-processing since you can't model it directly in eQUEST.
There can be some problems with using OA-FROM-SYSTEMS to model your DOAS,
too, but nothing that can't be overcome that I've seen.
