What is a Variable Refrigerant Flow (VRF) air conditioning system? Here’s the definition according to ASHRAE:
The term variable refrigerant flow refers to the ability of the system to control the amount of refrigerant flowing to each of the evaporators, enabling the use of many evaporators of differing capacities and configurations, individualized comfort control, simultaneous heating and cooling in different zones, and heat recovery from one zone to another. (ASHRAE Journal, April 2007)
In layman’s terms, VRF systems are essentially larger, more complex, versions of direct expansion (DX) split systems much like the one you likely have in your home. The technology was pioneered in Japan by Daikin back in the early 1980s, but has only recently gained popularity in the United States. These systems have continued to advance over the years, and numerous other notable manufacturers like LG, Mitsubishi, and Trane also offer versions of VRF systems.
The diagram above indicates how a single outdoor VRF condensing unit can serve various styles of indoor units (wall mounted, ceiling cassette, concealed ducted, PTAC style).
There are distinct Advantages of VRF over traditional systems, such as:
VRF systems do have a few Disadvantages as well:
With an initial investment, utilizing VRF technology on your next project can reduce energy costs, improve occupant comfort, reduce mechanical unit noise and reduce down time due to increased redundancy within the system.
