SeriesRZRooftop/Air HandlersAAON continuously strives to satisfy thedynamic industry requirement for largeenergy efficient packaged rooftop equipment.The RZ Series design incorporates the AAONlong term commitment and dedication toexcel as the premier manufacturer of rooftopequipment. RZ Series units are available inmultiple configurations and include manystandard features that make AAON synonymouswith quality products for any application.Premium EfficiencyCompressorsThe RZ Series Packaged Rooftop Unit includes variable speed compressors asstandard. Each interlaced evaporator coil includes one circuit with VFD variablespeed compressor for consistent air temperature across the face of the coil at alloperating conditions. During part load operation, reducing compressor capacitysaves system operating costs. The variable speed compressors use inverter drivenpermanent magnet motors for down to 11% unit turndown on some models. IEERpart load efficiencies for the RZ Series can be as high as 18.7.Variable Speed CompressorsProvide consistent supply air temperaturecontrol, load matching cooling, and highpart load efficiency.Supply FansThe RZ Series offers supply fan arrays with up to 12 fans using high efficiency directdrive airfoil plenum fans with optional permanent magnet motors. In the past whengreater airflows were required, the diameter of the single plenum fan was simplyincreased to meet the requirement. This resulted in higher tip speeds, which alsomeant higher sound levels. With the AAON RZ Series, greater airflow rates can beaccomplished with multiple fans of smaller diameter, which inherently will bequieter than a single larger diameter fan. All the fans are also directly driven bythe motor, which eliminates the drive belt assembly and associated maintenance.Supply Fan ArrayProvides quiet high efficiency operation with low maintenanceand built-in redundancy. Backdraft dampers are available.
The Benefits of Permanent Magnet Motor Technology versus AC Induction MotorsThe RZ Series supply fan array is designed around new permanentmagnet motor technology. These hybrid motors incorporate asynchronous reluctance rotor with permanent magnets to achieve anInternational Efficiency rating above IE5, which is the highest levelof efficiency today. The example chart below shows that this HybridPermanent Magnet Motor has the highest efficiencies at all loadconditions compared with the Electronically Commutated Motor (ECM)and the Premium Efficiency Induction Motor. The advantages of theHybrid Permanent Magnet Motor are even more significant at thelower fan speeds. Notice how much more efficient the HybridPermanent Magnet Motor is at reduced load (rpm) where variable airflow fans will operate during a majority of the time. Another advantageof this motor technology is it uses standard NEMA frames, which givesmore flexibility for replacement than proprietary designs.95%90%IE5)otor (net MMotor Efficiency85%HybridPermronicElect80%t Maganenotored Mutatommally C75%70%65%60%88011001320Application FlexibilityAAON has always offered a large number of features onour products to allow for application flexibility.
