How does a VRF air conditioner work?

VRF systems use heat pumps or heat recovery systems to provide powerful heating and cooling for all indoor and outdoor units without the use of air ducts. With a VRF system, your building will have multiple indoor units utilized by a single outdoor condensing unit, either with a heat pump or heat recovery system.

Is VRV better than split AC?

A VRF system typically works better in a commercial building structure with more square footage. Split AC units are ductless systems used more often in residential settings. You may also consider that a VRF system with heat recovery can simultaneously heat and cool different parts of a building.
