PQHY-P water cooled heat pump VRF (Variable Refrigerant Flow) systems use a water energy source system allows switching between cooling and heating.
The WY-Series has all the benefits of the Y-Series using water source condensing units. Condensing units can be situated indoors allowing greater design flexibility and no limitation on building size. Depending on capacity, up to 15 to 50 indoor units can be connected to a single condensing unit with individualised and/or centralised control. The indoor units can operate in either cooling or heating mode.
