Difference Between VRV and VRF
In the realm of modern HVAC systems, VRV and VRF systems are the most adaptable and effective options that focus on the cooling of new constructions. These systems are always grouped together and for a great reason, as these terms mean the same technology, differing only in the name.

Aircool Aircon is familiar with clients asking: Is there a difference between VRV and VRF? Do they mean the same, or is one genuinely superior?
This is the reason for writing this article, so you fully understand the differences and similarities of the VRV and VRF systems, how they function, and the one you should use for your project.
What is a VRF System?
The acronym VRF is for Variable Refrigerant Flow. This advanced HVAC (Heating, Ventilation, and Air Conditioning) system uses refrigerant as a cooling and heating agent. A VRF system is engineered to supply accurate climate control to several indoor zones from one outdoor condensing unit serving multiple indoor units.
A VRF system doesn’t turn on and off like conventional systems. By varying refrigerant flow to the zones depending on their needs, a VRF system improves energy efficiency and comfort.
Key Features of VRF:
Multiple Indoor Units: An outdoor unit can work with multiple indoor units at the same time, each with its own control.
Energy Efficiency: The systems adjust coolant flow to only use what’s needed, making them very efficient.
Quiet Operation: VRF systems maintain low noise levels, making them ideal for both business and residential environments.
Flexible Zoning: Different temperatures can be set and maintained in each room or zone.
Heating and Cooling Simultaneously: Heating and cooling in different zones at the same time is possible with some models.
These features make VRF systems ideal for use in commercial office buildings, hotels, retail stores, schools, and even in large residential buildings.
What is a VRV System?
VRV is an acronym for Variable Refrigerant Volume. This is a proprietary term invented by Daikin, a Japanese air conditioning firm, for this system in 1982. Daikin was actually the first to create the VRF system, but other manufacturers used the term VRF systems for similar products because Daikin reserved trademark for the term VRV.
In this case, a VRV system refers specifically to the VRF systems produced by Daikin.
To clarify:
VRV = Daikin’s branded version of VRF
VRF = The general industry term for this technology
Is There a Technical Difference Between VRV and VRF?
No, there is no technical difference between VRV and VRF in terms of how the systems operate. Both systems offer the same core features:
- Variable refrigerant control
- Energy-saving inverter technology
- Multi-zone temperature management
- Modularity and flexibility
- Quiet and efficient performance
The only real distinction is the branding. If you’re choosing a Daikin system, it’s called VRV. If you’re choosing a system from other manufacturers like Mitsubishi Electric, LG, Toshiba, Hitachi, or Samsung, it’s called VRF.
VRV vs VRF: Brand vs Technology
To help you understand more clearly, here’s a simple breakdown:
| Feature | VRF | VRV |
| Meaning | Variable Refrigerant Flow | Variable Refrigerant Volume |
| Term Type | Generic industry term | Brand name (by Daikin) |
| Origin | Used by multiple manufacturers | Exclusive to Daikin |
| Technology Difference | None – same working principle | Same as VRF |
| Common Usage | Mitsubishi, LG, Toshiba, etc. | Daikin systems only |
When you’re comparing VRV and VRF, you’re really comparing Daikin’s system to similar systems made by other companies. The performance, reliability, and efficiency will vary slightly depending on the brand and model — not because one is VRV and the other is VRF, but because of manufacturer design differences.
Benefits of VRV and VRF Systems
Be it a VRF (other brands) or a VRV (Daikin) system, you get the same benefits:
1. Energy Efficiency
The systems work on a demand basis and cut energy use through the regulation of refrigerant flow to only those areas that require it.
2. Zoned Comfort
This is best suited for buildings with a number of floors or rooms. It enhances user comfort by allowing each area to be controlled and reducing waste.
3. Scalability
Small and large installations both benefit from VRV/VRF systems. You can keep adding indoor units as and when required without the need to replace the entire system.
4. Quiet Operation
Their indoor units are designed to operate quietly, which makes them appropriate for offices, hotels, libraries, or even bedrooms.
5. Design Flexibility
These systems are small in size, with a sleek profile, allowing for more ways to install them. They also allow for piping runs to be either horizontal or vertical. Furthermore, their outdoor units can be mounted on a wall or on the rooftop.

Final Thoughts: VRV vs VRF – Which One Should You Choose?
In conclusion, VRF and VRV are the same, only they differ because of branding.
VRF is the standard term used by multiple HVAC manufacturers.
VRV, on the other hand, refers to the name Daikin coined for their VRF system.
Functionally and technologically, they operate identically. Other than that, the choice depends on brand preference, available models, warranties, pricing, and the installer’s expertise.
At Aircool Aircon, we like to think we deliver the best solutions to fit your specific needs. Our specialist staff can walk you through choosing, installing, and maintaining your systems — helping to keep your building comfortable while running efficiently and economically all year round.
