10.0pt;font-family:Arial;color:navy'>Using eQuest to model a single 240 sq. ft.
space with a window unit is a bit like using a backhoe to dig a hole for a
plant in your flower garden. From a technical perspective, PTAC is the closest
thing that comes to a window unit, but as to whether or not you use a heat pump
or not is totally dependent upon whether or not you want to analyze your window
performance with a PTHP or a PTAC with strip heat. Unless I’m not fully
understanding what it is you are trying to model…<o:p></o:p></span></font></p>

the residential business) there are some residential energy calculation tools
that probably would be much more appropriate for a micro-scale project like
this. I defer to the other eQuesters who may have more knowledge in this area
than me…<o:p></o:p></span></font></p>
