Energy-saving and High EfficiencyTaper pipe diffuser is applied in single stage compressor to improve compressorefficiency. The inner ring of Split Rational Diffuser (SRD) can rotate with load change,adjust area and direction of flow channel, thus greatly improve the part load performance and reliability of chiller.Vaneless diffuser designed for two-stage compressor, combined with inner-stageeconomizer improves chiller performance and makes it a better choice of high liftapplication.High performance tubing - Tubing with internally and externally enhanced finsimproves chiller performance by reducing overall resistance to heat transfer. The newheat exchanger reduces refrigerant charge and manufacturing cost.Carrier AccuMeter system regulates refrigerant flow according to load conditions,provides a liquid seal at all operating conditions and eliminates unintentional hot gasbypass. Thus ensure the part load performance of chiller. (Only for single e OperationVariable inlet guide vanes - The guide vanes are controlled by a precise electronicactuator. The vanes regulate inlet flow to provide high efficiency through a wide operatingrange.Diffuser design - Pipe diffuser design uses jet engine technology, increasing centrifugal compressor peak efficiency (single-stage only). Two-stage compressor utilizesvaneless diffuser to meet high lift application requirement with stable operation.Semi-hermetic Motors - Cooling is accomplished by spraying liquid refrigerant on themotor windings. This highly efficient motor cooling method also eliminates the potential for shaft seal leaks and refrigerant/oil loss.Environmental SustainabilityDesigned specifically for chlorine-free HFC-134a refrigerant(the environmentally balanced refrigerant with zero ozonedepletion potential)3
