told me to use an induction system in the guest rooms (I was heavily into Hilton
Hotels at the time). Such a system allowed primary and secondary heating and
cooling coils, and by using the bypass ratio, allowed outside air to
entrain. I don't have time to research the exact bypass ration, or all the stuff
I did (it was in DOE-2.1C version).</SPAN></FONT></DIV>

<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=738571821-10122003>But
that would allow you to use outside air with virtually a fan coil system, either
two or four pipe. Then the corridor air is on it's own loads and
system.</SPAN></FONT></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">I am using eQUEST to model a
high-rise multi-unit residential building (in a cold climate). The
mechanical system most likely for selection will include 2-pipe fan coils
(with a supplementary electric coil) in the suites and a corridor make-up air
unit. The in-suite fan coils under consideration have an outdoor air
intake and an air-to-air heat exchanger to recover heat from the suite
washroom exhaust. This is not how the FC fan coil system is set up in
DOE 2.2 - and there is no provision for heat recovery at the fan-coil
level. I am using the OA-FROM-SYS keyword which moves the entire
ventilation load to the corridor make-up air system where heat recovery can be
applied. Doing this appears to greatly improve the energy performance of
the building. I am wondering if modeling the system in this was is
over-stating performance of the heat recovery.</SPAN></FONT></P>

experience within the group to better model such a system. Any
assistance would be greatly appreciated.</SPAN></FONT></P>
