The Carrier 19XR/19XRV with a COP up to 6.5 (AHRI conditions) and an IPLV up to 7.4 or up
to 10.5 with VFD centrifugal chillers provide exceptional value by achieving energy efficiency
levels as high as 6.8 (EER) utilising proven technology designed specifically for chlorine-free
refrigerants:
■■ Interstage economizer to improve efficiency and increase capacity.
■■ Unique concept of the hermetic compressor:
-- Dual-stage aerodynamic impeller
-- Vane-less diffuser to meet high lift application requirement with stable operation
-- Motor cooled by spraying liquid refrigerant on the motor windings.
■■ Possibility to control the compressors using a variable frequency drive (19XRV) to
maximise machine energy efficiency.
■■ Use of high-efficiency evaporator and condenser tubes
■■ Expansion sub-cooler integrated into the condenser
■■ Patented float valve technology for optimised sub-cooling and refrigerant level in the
evaporator
These advantages, together with the modularity of the units and their efficiency, economical
operation and dimensional constraints allow the use of the Carrier 19XR/19XRV two-stage
centrifugal chillers in any high-capacity water cooling applications such as air-conditioning,
heat-pump, energy recovery, ice thermal storage, marine, VFD and high-voltage applications.
