<p class="MsoNormal">I am wondering if anyone has any experience with the
following type of modeling in equest.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The building I am working on is an apartment building where
they are planning to install a variable refrigerant flow system with rooftop
heatpumps. The refrigerant will be routed from the rooftop to individual
airhandlers in each apartment. I don’t think equest has this as one
of their system types, and I think the closest thing would be a packaged
terminal heat pump. The apartments all meet ASHRAE requirements to use
natural ventilation, but as I understand it equest does not allow natural
ventilation to be used with this system type. Have I passed over a better
option for modeling this system, or does anyone know how I could include
natural ventilation in the model. From what I’ve read it looks like
I’ll have to create another model for natural ventilation and use the
exceptional calculation method.</p>
