VRV and VRF Air Conditioning Systems: What Are the Differences

VRV & VRF Air Conditioning Systems: What Are the Differences?

VRV (Variable Refrigerant Volume) and VRF (Variable Refrigerant Flow) systems have revolutionised the way we control indoor climate, making them popular choices for commercial and residential spaces in Singapore. In fact, you may have heard of these terms while shopping for your ideal aircon system. However, what are the differences between VRF and VRV aircon? Both seem to offer identical benefits. So what separates the two systems? Let us find out!

What are the differences between VRF and VRV systems?

Due to their naming conventions, many mistakenly assume that VRF and VRV systems are two different HVAC (Heating, Ventilation, and Air Conditioning) technologies. That is an honest mistake to make. However, in function and design, they are almost identical. So why are there two distinct terms for the same technology?

This difference dates back to the early 1980s, when Daikin, a technology leader in the HVAC industry, invented the first VRV system. Subsequently, Daikin registered “VRV” as an official trademark, making it impossible for other brands to use this term legally. To circumvent this problem, other companies have used “VRF” to describe similar HVAC systems. Basically, the difference between the two boils down to the copyright for Variable Refrigerant Volume.

How do VRF/VRV systems work?

The operation logic of a VRF or VRV aircon is built-in inside the system and is proprietary for each manufacturer. Nevertheless, the principle remains the same. Both utilise a single outdoor unit connected to multiple indoor units. The outdoor unit regulates the refrigerant flow based on the individual requirements of each indoor unit, allowing for precise temperature adjustments in various zones simultaneously. As a result, users enjoy precise climate control, personalised comfort, and exceptional energy efficiency.

Benefits of a VRF/VRV aircon system

Benefit #1: Energy-efficient

With rising electricity tariffs, Singaporeans are undoubtedly looking at all avenues to reduce their monthly expenses. VRF/VRV systems offer just that. Unlike traditional water-cooled and ducted systems based on chillers and fan coils, VRF/VRV aircon does not lose energy through ductwork. Moreover, these systems can eliminate energy wastage thanks to their ability to adjust the refrigerant flow according to the cooling demands of each indoor unit. All of this translates to lower utility bills and a more eco-friendly operation.

Benefit #2: Individual temperature control

Thanks to VRF/VRV aircon, it is possible to achieve individual temperature control in different areas or rooms. With multiple indoor units, each space can be customised to its occupant’s preferences, allowing for diverse temperature settings in various zones. This level of control ensures maximum comfort for everyone while eliminating the redundancy of cooling unoccupied areas, further contributing to energy savings.

Benefit #3: Flexible design

VRF/VRV systems offer tremendous flexibility in system design and installation. Thanks to their capability to connect numerous indoor units to a single outdoor unit, they are adaptable to various building layouts and sizes, thus meeting the specific needs of any given space. This modular design accommodates easy expansion or modification in the future, making VRF and VRV systems a cost-effective and scalable solution for residential and commercial buildings.

In summary, deciding between a VRF or VRV aircon boils down to brand preference. Both systems are energy-efficient, provide personalised comfort, and are ideal for spaces of all sizes and layouts. We recommend choosing a model and brand based on your space requirements, budget, and maintenance frequency to ensure the system is ideal for your cooling needs.
