So what exactly is VRF?
VRF or Variable Refrigerant Flow is a technology invented by Daikin in 1982. Daikin now calls their VRF systems VRV or Variable Refrigerant Volume. VRF systems use mostly ductless air handlers or “Heads” to cool or heat conditioned spaces using refrigerant as opposed to conventional systems supplying conditioned air through ducted systems. Because the conditioned space is being supplied by the conditioned air it requires closer (often directly in the room), the space is conditioned to its optimum requirement. In a conventional system conditioned air must travel through an often leaking ducted system losing much of its heating/cooling (duct losses).
