The company has released a new line variable refrigerant flow heat pumps.
Fujitsu General America, Inc. has introduced Airstage™ V-II VRF, a new line of variable refrigerant flow (VRF) heat pumps.
This large capacity, zoned heat pump system with operational efficiencies up to 21.7 iEER (to AHRI 1230 standard) is the perfect fit for small and large buildings. Airstage systems avail a lineup from 6 to 24 tons with a connectable indoor unit capacity ratio up to 130% and up to 45 indoor units per bank of 3 condensing units.
High efficiency is achieved by using a single DC inverter-controlled, twin rotary compressor per condenser. The system also boasts a total pipe length of nearly 3,300 ft. Heating operating range spans ambient temperatures from 75°F to as low as -5°, while rated cooling capacity remains constant with outdoor temperatures from 115° to 14°.
Indoor units come in a variety of styles: wall mount, cassette, compact duct, floor/ceiling mounted, and high static pressure duct. Up to three condensing units may be linked with twining kits. Applications include churches, medical facilities, office buildings, and schools.
Web monitoring capability, low noise design, easy service and maintenance, and peak cut operation make the new Airstage systems an ideal choice for installing and service contractors and building owners.
Fujitsu Training Academyoffers classes online, at remote locations, and at the Fujitsu VRF Training Center in Fairfield, New Jersey. Fujitsu Training Academy provides training for contractors and engineers on the design, installation, troubleshooting and diagnostics of VRF systems.
