Hitachi SmartFlex™ variable refrigerant flow systems achieve extremely high efficiencies by modulating the flow of refrigerant according to the exact demands of individual areas.

A VRF system typically consists of one or more outdoor units from which refrigerant is piped to a series of indoor fan coil units serving individual zones within building spaces. The system conditions the spaces by delivering to the indoor fan coil units only the volume of refrigerant required to meet the heating or cooling needs of each zone.

There are two basic types of Hitachi SmartFlex™ VRF systems, ranging in capacity from 3-36 tons: Heat pump VRF systems are two-pipe systems. Heat recovery VRF systems are three-pipe systems.

Then there's the ground breaking introduction of the Hitachi SmartFlex™ VRF Gen II system. This technological advancement builds upon the game-changing innovations that make variable refrigerant flow systems the most flexible and energy-efficient HVAC solutions in the world. These brand new systems offer greater performance, more design freedom and exceptional control. Plus, with an expanded unit lineup and extended operating temperature ranges, Hitachi SmartFlex™ VRF Gen II systems make it easier than ever to keep indoor climates absolutely perfect.

Heat Pump and Heat Recovery VRF Systems

Heat pump VRF systems are two-pipe systems that enable design for non-ducted or ducted applications. Precise heating or cooling is delivered to multiple zones.

Heat recovery VRF systems are three-pipe systems that also enable design for non-ducted or ducted applications. Precise heating and cooling is delivered with an extra measure of flexibility, since the system can provide simultaneous heating and cooling while transferring any excess heat or cooling from one zone to another.
