Variable Refrigerant Flow (VRF)

With VRF technology, heating and cooling only the spaces that need it is simple. These systems circulate the minimum amount of refrigerant needed for each individual zone to satisfy the building load. Since there are no ducts, this eliminates the energy waste associated with the duct loss.

A single VRF system can power up to 64 independent indoor units, depending on the system. This provides superior zoning because the refrigerant flow can vary from location to location, delivering only the necessary capacity to each zone.

  • Carrier is the only manufacturer in the marketplace that offers 2-and 3-pipe heat recovery systems to help better layout the system depending on your building layout design and needs.
