<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The term packaged refers to a unit where
all of the components: fan, compressor, coils, controls, etc., are in one
enclosure, or “package.” The typical example would be a rooftop
unit where all of these components are contained in one cabinet. A different
type is a “split” system where the condensing unit and compressor
is separate from the air handling unit which contains the fan, filters and
coils and the two are connected by refrigerant lines. These are most common in
residential and small commercial systems (i.e. 5 tons or less).<o:p></o:p></span></font></p>

everyone:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>This
is a question puzzled me for a long time, what's the meaning of
"packaged" in the air condition system?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>ASHRAE
90.1 appendix G shows 8 types of the different HVAC systems in the table G
3.1.1 B(see the illustration below), but I can’t make the difference
between the 8<sup>th</sup> form others.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Calibri><span style='font-size:11.0pt'>What
should I do in the simulation if a HVAC system is “packaged”? And
what about the “unpackaged” ? You can see that this is the
only different between item 7 & 8 .<o:p></o:p></span></font></p>
