Most people remember the children’s tale about Goldilocks and the three bears. One of the bears found his soup too hot, another found his soup too cold, and the third found his soup “just right.” That illustration is now referred to as the “Goldilocks Principle.” In planetary terms, Venus is too hot, Mars is too cold, and earth is just right. In human terms, each body, with its organs and systems wants to be, yes, just right. VRF technology is a great way to deliver “just right” temperatures to your commercial space.

What is VRF Technology?

Variable Refrigerant Technology (VRF) is simply described as a large-scale ductless HVAC system that performs at a high capacity. It provides the ability for a single system to operate multiple indoor units or zones. A VRF system can be either a heat pump or heat recovery system and it can provide simultaneous cooling or heating. That is, some rooms can be cooled at the same time other rooms are being warmed.

VRF technology was developed in Japan in 1982, and it now allows 40 to 50% efficiency improvement versus a standard rooftop unit (RTU.) A rooftop unit requires a cooling source, a heating source, intakes and ductwork throughout your commercial space. According to the General Services Administration, VRF technology is now the primary HVAC approach chosen for use in Europe, Japan, and China.

VRF Technology Facts and Myths

Fact: VRF systems provide simultaneous heating and cooling in different zones or rooms in a building at the same time, controlled by building occupants.

Myth: VRF systems are only available for commercial use. In fact, VRF systems can be scaled for large and small commercial applications or for single-family dwellings.

Fact: VRF systems are extremely quiet, reducing noise both inside and outside of a building.

Myth: VRF systems are large and bulky. In fact, VRF systems are quite sleek and compact compared to traditional HVAC equipment.

Fact: VRF systems are easy to install. Of course, VRF technology should be installed and maintained by factory trained and certified companies.

Fact: VRF systems can be installed in both retrofit applications and new construction.

Great Reasons to Choose VRF Systems

VRF systems can operate effectively in individual residents, high-rise housing, large and small commercial buildings, restaurants, retail stores, and office spaces.

Choose these advantages of VRF technology:

Heat and cool simultaneously, in customized zones

Consistent comfort

Operationally quiet

Excellent energy efficiency

Installation flexibility and an excellent use for tight spaces

State-of-the-art controls

Reliability—fewer breakdowns and less downtime

Considerations When Choosing a VRF System

Consider the following when choosing a VRF system:

Higher up-front cost. VRF technology may cost more than traditional HVAC systems to install, but this cost will be offset by lower energy bills and repair expenses over time.

Requires an experienced installer. VRF systems are sophisticated and require a trained and experienced installation team.

Get expert installers to review the heating and cooling capacity needs of your building before choosing a brand.

Get expert VRF technology assistance to maintain your units.

Make Sure to Properly Maintain Your VRF System

Like any other HVAC system, a VRF system does need to be regularly checked and properly maintained by skilled professionals. Make sure to choose a facilities maintenance company with the right experience; someone you can rely on to protect your valuable investment. Get “just right” installation and maintenance service to match your “just right” temperatures.
