[EnergyPlus_Support] Re: about the window air conditioner
The window air conditioner model in EnergyPlus is "cooling only". In
the example file WindAC.idf, the window air conditioner
is coupled with a hot water baseboard heating system.
A packaged terminal heat pump model (providing both heating and
cooling) is scheduled to be added to EnergyPlus by the Fall 2005
release.
EnergyPlus contains a model that can be used for residential
heating/cooling, which involves an air distribution system (common in
the U.S.). See object "Furnace:Blowthru:HeatCool" in the IO Reference
and the Engineering Doc. An example file is also provided:
FurnaceWithDXSystem.idf
