VRF Vs. VRV: Major Differences And Working

It might be challenging to choose the proper air conditioning system for your new structure. There are numerous options accessible, each with its own set of advantages. A VRV (variable refrigerant volume) and VRF (variable refrigerant flow) air conditioning system is highly energy-efficient and can rapidly cool an entire building. However, what is the distinction between VRV vs VRF? Take a look at the differences between a VRV and a VRF system and the advantages of this technology.

VRF In Comparison To VRV

Some people assume that the VRV and VRF air conditioning systems are two separate HVAC systems. In reality, both systems rely on the same technology. Daikin originally invented VRV systems in the early 1980s. Because this business was the market leader, they trademarked the VRV brand to characterize the technology. Other companies began using the name VRF to describe their systems when they adopted the same technology. VRF has been the standard term for describing the kind of HVAC system since it uses the same technology.

What Do The Terms VRF And VRV Mean?

VRV and VRF stand for “Variable Refrigerant Volume” and “Variable Refrigerant Flow,” respectively. To begin with, they both imply the same thing! VRF stands for variable refrigerant flow and refers to the same fundamental technology utilized in systems made by different businesses.

What Exactly Is VRF?

A VRF is one of the most sophisticated and energy-efficient air conditioning systems available compared to other HVAC systems. A VRF has four distinguishing characteristics. To begin with, these systems merely employ refrigerants to chill the air. It is a significant improvement compared to a typical HVAC system that utilizes water to cool the air. The refrigerant in a conventional system cools the water, which is then cycled throughout the system.

A VRF employs an inverter compressor. These low-energy compressors have a low power consumption and only allow the unit to extract enough energy to cool the system partially. VRF also includes numerous air handlers that can be linked inside the same refrigerant loop. Finally, this distinguishing characteristic allows VRF to develop modularly to accommodate expanding projects.

The Working Of A VRF

A VRF air conditioner is a high-efficiency machine that cools the indoor area by considering both the internal and outside temperatures. Each VRF device from different manufacturers has its unique set of algorithms, but they all work similarly. The VRF device begins to operate once the interior temperature is preset to the appropriate setting. The device considers the outside ambient temperature while calculating how to generate the ideal interior temperature. It is the distinguishing feature of a VRF unit and the reason for its efficiency.

Once the device has completed the calculation, the compressor will only run with enough energy to satisfy the interior’s intended temperature needs. In addition, if a secondary VRF unit is activated, the system recognizes the need for a new computation. To achieve the required interior temperature, the VRF unit considers the present ambient outdoor temperature, the contribution from a secondary unit, and the internal temperature. VRF units may be put together and still function as a unit. The VRF unit is an ideal solution for growing projects due to its modular design.


Most houses do not have one ample, open space. While ductless AC and central systems can help with inconsistent temperatures’ difficulties in houses, the VRF system takes it to the next level. These systems make use of several indoor units around the home and adjust the refrigerant flow to match the individual demands of each room.
