It’s energy efficient, quiet and useful for many functions, such as controlling temperature, air quality and humidity in line with each room’s purpose. Zones let it provide specific temperatures to different areas, whether for an apartment building, stores, offices, warehouses, or other commercial structures.

It is a relatively new option to Variable Air Volume, a long-popular system that is valuable for energy efficiency while controlling temperature and airflow.

A couple differences:

• VAV requires ducts while VFR does not.

• In VFR, the system can simultaneously cool one part of a building while heating another part.

Choices

A property-owner has options:

• Upgrade the existing VAV

• Install VRF parts in a system that had been using VAV

• Turn to other HVAC systems, such as heat pumps, packaged systems and split systems.

More options

Heat pumps are versatile energy=savers that  can be used with existing HVAC systems that provide cooling and heating.

Split systems are popular with bigger commercial buildings because they can provide heating and cooling to different areas at the same time.

Packaged systems are space-savers that also can simultaneously provide heating and cooling.

Before choosing a system, the owner of a commercial building should enlist a contractor who is an authority on commercial HVAC to help guide decisions.
