[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

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:
