THE DAIKIN R-32 VRV CHILLER – AVAILABLE IN SPLIT VERSION WITH R-32 REFRIGERANT

New split-version models have been added to the Daikin R-32 VRV Chiller series in late summer 2022 . This addition to Daikin ' s extensive portfolio of VRV chillers uses climatefriendlier R-32 refrigerant .

EFFICIENT HEATING AND COOLING The inverter-controlled heat pump is available in 21-64kW capacity classes and can be used for heating and cooling buildings of different sizes . The Daikin R-32 VRV Chiller easily adapts to different cooling and heating requirements with supply temperatures of + 60 ° C for heating or

-15 ° C in cooling mode . With a SEER ( seasonal energy efficiency ratio ) as high as 5.7 and a SCOP ( seasonal co-efficient of performance ) up to 4.2 , this heat pump delivers remarkable efficiency with low running costs . Thanks to its compact design and integrated safety system , the heat pump can be installed in tight spaces .

FOCUS ON SUSTAINABILITY Daikin is planning to convert its entire portfolio of chillers that use R-410A refrigerant to the more climate-friendly R-32

refrigerant . While R-410A refrigerant has a GWP ( globalwarming potential ) of 2 088 , the GWP for R-32 is only 675 – which significantly reduces CO 2 emissions . Following the introduction of a compact version of the R-32 chiller in October 2021 , the entire production of the corresponding R-410A series was relocated from Ostend in Belgium to Italy .

The same process is being carried out for the split version of the chiller . By switching its entire product range to R-32 refrigerant , Daikin is setting a benchmark for sustainability and the futurefocused development of the industry .
