Many people who ask this question mistakenly interpret it as 2 different HVAC technologies.

​Actually, those are two different terms for the same type of HVAC technology. Based on inverted technology compressors, the first VRV HVAC systems were invented by Daikin during the early 1980’s. As a technology leader in the HVAC industry, Daikin had registered the VRV term (which stands for Variable Refrigerant Volume) as an official trademark. All other companies use VRF (Variable Refrigerant Flow) for their similar HVAC systems.

Eventually, VRF is the more common term for these types of systems, and this is the term that will be used for the rest of the articles.

Variable Refrigerant Volume (VRV) and Variable Refrigerant Flow (VRF) mini-split systems revolutionize heating, ventilation, and air conditioning (HVAC) technologies, offering precise temperature control and energy efficiency for both residential and commercial spaces.

Understanding VRV vs VRF Mini-Split Systems

VRV vs VRF: An Overview

  • VRV: Coined by Daikin Industries, VRV stands for Variable Refrigerant Volume, denoting their specific brand of VRF systems.
  • VRF: Variable Refrigerant Flow is a broader term encompassing similar systems from various manufacturers.

Functionality and Operation

  • VRV/VRF: Both systems operate on the principle of modulating the flow of refrigerant to multiple indoor units based on the specific cooling or heating demands of individual zones.
  • Benefits: This granular control allows for greater energy efficiency by minimizing energy waste and maintaining precise comfort levels in different areas.

Individualized Climate Control

  • VRV/VRF: These systems excel in offering individualized climate control. Each indoor unit can be controlled independently, allowing different zones to have varied temperatures simultaneously.
  • Advantage: Users can tailor the climate in different rooms according to preferences and occupancy, optimizing comfort levels.

Energy Efficiency

  • VRV/VRF: By adjusting the refrigerant flow based on real-time demand, these systems prevent excessive energy consumption.
  • Advantage: They minimize energy wastage by only supplying the necessary cooling or heating to specific zones at any given time.

Installation and Flexibility

  • VRV/VRF: Mini-split systems offer flexibility in installation. They require smaller conduits and can be easier to install in retrofit applications or buildings with limited space for ductwork.
  • Advantage: This flexibility suits various architectural layouts and building designs.

Brand-Specific vs. Generic

  • VRV: Specific to Daikin, it incorporates patented technology and might have specific components tailored for compatibility within Daikin’s ecosystem.
  • VRF: Represents a more generic term encompassing similar systems from different manufacturers, offering varying features and compatibility options.


In conclusion, VRV and VRF mini-split systems represent cutting-edge HVAC technology that prioritizes energy efficiency, precise temperature control, and individualized comfort. While VRV denotes Daikin’s proprietary VRF system, VRF refers to similar systems from various manufacturers. Both systems offer versatile solutions for spaces requiring zoning capabilities and efficient HVAC operations. Understanding their functionalities, energy-saving benefits, and installation flexibility can guide users in selecting the ideal system tailored to their specific needs and preferences.
