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.
The CITY MULTI WR2 series provides all of the advantages of the R2 series with the added benefits of a water heat source system, making it suitable for wider range of applications in high rises, frigid climates, coastal areas, etc.
Not only does it produce heat recovery from the indoor units on the same 2-pipe refrigerant circuit, it also produces heat recovery via the water circuit between heat source units, making it a very economical system.
