Variable Refrigerant Flow (VRF) & Ductless
Variable Refrigerant Flow (VRF) is a high efficiency HVAC technology for cooling and heating.
VRF uses refrigerant as the cooling and heating medium, which is distributed throughout the building from an outdoor unit to various zoned indoor units.
VRF systems utilize modulating compressors and fans to match the system’s capacity to meet the required cooling and heating load in each zone.
The historic Stonewall Building, built circa 1925, is a 12-story building in downtown Birmingham, Alabama. The building went through an extensive renovation converting to office spaces and residential lofts. From an engineering standpoint, it was a challenge to provide heating and cooling on an existing building with limited ceiling space for ductwork.
