  1. When Daikin launched the VRV air conditioning system in 1982, it introduced the world’s first use of variable refrigerant flow control. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones.

    Variable refrigerant flow (VRF), also known as variable refrigerant volume (VRV), is an HVAC technology invented by Daikin Industries, Ltd. in 1982. Similar to ductless mini-split systems, VRFs use refrigerant as the primary cooling and heating medium, and are usually less complex than conventional chiller -based systems.

    When Daikin launched the VRV* air conditioning system in 1982, it introduced the world’s first use of variable refrigerant volume control. Also referred to as a VRF system, variable refrigerant flow is a technology that circulates only the minimum amount of refrigerant needed during a single heating or cooling period.

    In a nutshell, VRF is a ductless, large-scale system for HVAC that performs at a high capacity. Unlike split AC equipment, VRF allows multiple indoor units to run on the same system, which is designed differently depending on the application.
