[Equest-users] window heating and cooling unit

[Gary.Schrader at buildings.schneider-electric.com]

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...

 

While I have not used them, (we are not in 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...

 

Thanks,

Gary

Subject: [Equest-users] window heating and cooling unit

 

I am modeling a small space of 240 sf and want to use window /wall unit
for both heating and cooling . I am analysing the performance of windows
in different climate zones.

So does anyone know which system should be used for that.

I was checking the pacakaged terminal heat pump system with dx coil
cooling and heat pump heating.

other system was dx coil cooling and electric coil heating with packaged
terminal AC.

not very sure how to model these.

any help is highly appreciated.

Regards

Deepika
