In EnergyPlus, the AirLoopHVAC:UnitaryHeatPump:AirToAir system is what you describe. This system serves multiple zones. If you are conditioning only one zone, use the ZoneHVAC:PackagedTerminalHeatPump. These systems use both a cooling and heating coil to model both modes of operation even though the real system has only one indoor coil. Look at the example file HeatPump.idf to see how the multizone air loop is configured, or look at PackagedTerminalHeatPump to see how the zone heat pump is configured.
