[BLDG-SIM] Heating and Cooling ventilation system

[Aulbach, John]

Chris:

Can you use the single zone reheat system (SZRH), which CAN accomodate an
economizer? This could be Done in either 2.1E or 2.2. Just jury rig it so
that the cooling and heating coils don't operate simultaneously.

By the way, this IS a chilled water/hot water system, correct?

Realize these systems are just statistical Btu generators within the
program, so you can call a system something, but yet make it act like
something else.

I am looking to simulate a four-pipe fan coil with economiser 
control.  This is not possible with DOE2.1E and when I scan the DOE2.2 
documentation it looks like it also lacks the capability to simulate a
fan 
coil system with economiser control.  The system I want to simulate is a

unit-ventilator with heating and cooling coils, an outdoor air damper
with 
economiser control.  This type of system is being used in schools - new
and 
retrofit.  An example of a configuration is discussed in "TPFC for
Schools 
(Esource).pdf" an Esource article.  My client is interested in
converting 
from hot water convectors to a two or four pipe unit ventilator.

Thanks for any insight into simulating this configuration.
