Trane TruComfort Variable Speed Systems
www.trane.comStaging refers to an air conditioner’s or heat pump’s ability to run at different capacities in order to increase comfort levels and boost efficiency. For example, two-stage systems offer better comfort and higher efficiency than single-stage systems, while Trane’s TruComfort ™ variable speed system, with 500 to 750 stages, offers

www.pentair.comCirculation systems operate under high pressure. When any part of the circulating system (i.e. locking ring, pump, filter, valves, etc.) is serviced, air can enter the system and become pressurized. Pressurized air can cause the pump housing cover, filter lid, and valves to violently separate which can result in severe personal injury or death.
VARIABLE SPEED PUMPING - Energy
www1.eere.energy.govways, with the most popular type of variable speed drive (VSD) being the variable frequency drive (VFD). Pump speed adjustment is not appropriate for all pumping systems, however. This overview provides highlights from Variable Speed Pumping — A Guide To Successful Applications, which has been developed by Europump and the Hydraulic Institute

The heart of the system is the Copeland variable speed compressor powered through the use of the Emerson variable speed drive (VSD) inverter control. By Combining an ECM outdoor fan, Emerson
HVAC Variable Refrigerant Flow Systems
www.seedengr.comVariable refrigerant flow systems with heat recovery (VRF-HR) capability can operate simultaneously in heating and/or cooling mode, enabling heat to be used rather than rejected as it would be in traditional heat pump systems. VRF-HR systems are equipped with enhanced features like inverter drives, pulse modulating electronic expansion

Variable Refrigerant Flow (VRF) Systems
www.shareddocs.comAll VRF systems provide energy savings by varying compressor speed and matching the output of the system as closely as possible to the load. In addition, VRF systems do not experience the same energy losses as systems that move conditioned air through ductwork. However, differences in design the available in
