A scroll compressor is typically used in smallmedium size HVAC applications for residential and commercial buildings . It offers a good compromise between a compact footprint and wide operating envelope . A typical application is a multi-compressor system , often with one inverter compressor for more flexible regulation and improved efficiency .
A rotary-screw compressor uses a rotarytype positive-displacement mechanism . Screws are commonly used for medium size comfort or process cooling applications where high compression ratios and lift are required , such as for glycol or dry cooler operation .
Variable compression ratio ( Vi ) and slide valve can provide the best efficiency while matching the different operating conditions required by each application .
A centrifugal compressor adopts a radial design and it is capable of achieving the refrigerant ’ s pressure increase by adding kinetic energy to a continuous flow . Suitable for large refrigerant volumes and cooling capacities , YORK proprietary design is based on a single stage compressor and Inverter VSD to match all the operating conditions by RPM speed . Typically one single impeller is capable of achieving approx . 40 ° C refrigerant lift . Compared to screws , this type of compressor is less suitable for glycol or dry cooler but provides the highest efficiencies at low lift operation , such as for high setpoint cooling ( e . g . Data Centers ).
