VRF, or Variable Refrigerant Flow, is HVAC technology invented by Daikin in 1982, and is also known as Variable Refrigerant Volume (VRV). VRF/VRV systems use mostly ductless air handlers known as heads and refrigerant to cool or heat conditioned spaces, as VRF/VRV systems use mostly ductless opposed to conventional systems that supply conditioned air through ducts.
In a conventional system, conditioned air must travel through an often-leaking ducted system where it loses much of its heating/cooling (known as duct loss). VRF/VRV helps prevent that leaking, conditioning the space to its optimum requirement.
VRF/VRV systems have benefits such as:
• Quiet running
• Simultaneous heating & cooling
• Architectural design flexibility
• Outdoor unit capabilities
• Green technology
