Product Data EVERGREEN® 19XR,XRV High-Efficiency Hermetic Centrifugal Liquid Chiller 50/60 Hz HFC-134a 200 to 1500 Nominal Tons (703 to 5275 kW) ® evergrn Carrier’s Evergreen® centrifugal chillers offer: • The use of non-ozone depleting refrigerant HFC-134a, which is not affected by scheduled refrigerant phaseouts • An annual leak rate of 0.1%, the lowest published in the industry • The ability to store the entire charge of refrigerant inside the chiller, minimizing the chance of leaks during refrigerant transfer for maintenance • Hermetic compression • Refrigerant-cooled VFD (variable frequency drive) (19XRV only) • Modular construction • Positive pressure design • Variable diffuser optimization logic, which can improve the integrated part load values (IPLV) (available on compressor frame sizes 4 and 5 with diffuser control enabled) The Carrier-designed Evergreen family of chillers achieve superior efficiencies without compromising the environment. The Evergreen chillers superior efficiencies are obtained at true operating conditions. Therefore, the effects of potential direct or indirect global warming are greatly diminished. * Meets IBC 2006, ASCE-7-05, CBC 2007, and OSHPD seismic requirements. Copyright 2011 Carrier Corporation High efficiency Today’s owners of chilled water plants demand high efficiency from their chillers. Per AHRI (Air Conditioning, Heating and Refrigeration Institute) 550/ 590, chillers operate at design conditions less than one percent of the time.

Features/Benefits (cont) As a result, superior part load efficiency is required for today’s chilled water applications. The Evergreen® 19XRV centrifugal chiller, equipped with a factoryinstalled variable speed drive, maximizes chiller efficiency by optimizing compressor operation. Electric power consumption drops dramatically when the motor speed slows. The 19XRV chiller delivers industry-leading integrated part load values (IPLV). The Evergreen chiller with diffuser control enabled (available on compressor frame sizes 4 and 5) improves the chiller’s part load efficiency by increasing the...

with air-cooled designs of the same type. In addition, Carrier’s hermetic design eliminates: • Compressor shaft seals that require maintenance and increase the likelihood of refrigerant leaks • Shaft alignment problems that occur with open-drive designs during start-up and operation, when equipment temperature variations cause thermal expansion • High noise levels that are common with air-cooled motors, which radiate noise to the machine room and adjacent areas • Machine room cooling requirements associated with air-cooled motors, which dissipate heat to the machine room Compressors are...

Features/Benefits (cont) Configuration data backup in nonvolatile memory provides protection during power failures and eliminates time consuming control reconfiguration. 19XR refrigeration cycle The compressor continuously draws refrigerant vapor from the cooler at a rate set by the amount of guide vane opening. As the compressor suction reduces the pressure in the cooler, the remaining refrigerant boils at a fairly low temperature (typically 38 to 42 F [3 to 6 C]). The energy required for boiling is obtained from the water flowing through the cooler tubes. With heat energy removed, the...
