Creating both attractive designs and occupant comfort in commercial buildings is easy with the right HVAC system. Variable refrigerant flow (VRF) systems offer architects more design freedom than conventional HVAC systems.

Designed to provide efficient, personalized comfort to almost any building design, VRF systems use small refrigerant lines to move refrigerant, instead of conditioned air, to every zone requiring heating or cooling. The conditioned air is made in the zone it serves. Easy to integrate into building designs, the systems are compact, flexible, and available in a variety of indoor unit styles including wall-mounted, floor-standing (concealed and exposed), ducted, and ceiling (cassette and concealed) options.

Working in tandem with integrated controls and sensors to measure heating and cooling demand for each zone, the outdoor unit’s compressor seamlessly adjusts its speed to maintain the zone’s desired temperature. While fixed-speed compressors in conventional HVAC systems are either running at full power or turned off, the INVERTER-driven compressor of a VRF system continually adjusts the flow of refrigerant to precisely meet the conditioning requirements of the building.

When ductwork is needed, it is often low-profile and short-run and can be installed in tight spaces. This saves ceiling space within the building while providing more efficient cooling and heating.
