VRF Systems

What are VRV/VRF Systems?

A VRF system is a very sophisticated HVAC system that uses refrigerant as the cooling and heating medium. They are special systems that are gaining popularity and are considered as enhanced versions of multi split systems. They feature heating and cooling, as well as heat-recovery capabilities.

But what does VRF system stand for? What is VRV and VRF technology?

There are people who erroneously assume that VRV and VRF are different. This is really not the case. The two are the same. The only difference is in the full meanings of their acronyms:

  • VRF stands for Variable Refrigerant Flow while VRV stands for Variable Refrigerant Volume, check Daikin VRV for details. Though there is little difference in the names, VRF and VRV refers to the same HVAC technology that was invented by Daikin Industries, Ltd. in 1982.

The Structure of A VRF System

Though there may be minor variations, VRF systems are generally the same. They typically contain an outdoor unit that contains one or multiple compressors, several indoor units that are erroneously called ‘fan coils’ by some people, refrigerant piping that run from the outdoor unit to all the indoor units, using Refnet Joints, and communication wiring. The communication wiring essentially comprises of two wired cables that create an internal closed loop network that is considered an essential part of the VRF installation.


Advantages of the VRF System

The VRF system offers some advantages over the traditional HVAC system. The prominent ones include:

  • Construction Flexibility – The entire system is relatively simple to install and allow for future expansion.
  • Energy Efficiency – The system is significantly energy-efficient when compared to the traditional system. This is not only good for your pocket but also helps minimise environmental impact of air conditioning.
  • Good Zoning Control – VRF systems provide simultaneous cooling and heating with heat-recovery. Overall, each zone will be efficiently controlled to improve occupant comfort.
  • Quiet Performance – VRF systems make less noise than traditional split systems and this significantly improve comfort for users.

Possible Disadvantages

Though they are generally great, VRF systems are not flawless. There major disadvantages include:

  • Initial Cost – Normally, VRF units are more expensive than traditional HVAC systems. Though the savings in energy bill can return the investment within some years, the initial cost can hinder some households.
  • Multiple Branch Connections – The need for long refrigerant lines and large number of branch connections makes the systems prone to refrigerant leakage. Which is why we always suggest having these types of systems installed by ARC registered and dealer authorised installers.

Variable Refrigerant Flow systems are great HVAC solutions. They offer a number of advantages over the traditional systems. You can choose them for your next HVAC system but make sure you understand the implications very well.
