Blue Star VRF System

Variable Refrigerant Flow (VRF) HVAC systems consist of outdoor units connected to multiple indoor units via refrigerant piping to provide cooling and heating to individual zones.VRF systems include two major components, a compressor with outdoor coil and multiple indoor fan coil units. The outdoor unit houses the compressor which acts as a pump pushing refrigerant through piping to the indoor coils and back.VRV is short for “Variable Refrigerant Volume,” and VRF is “Variable Refrigerant Flow.” And they both refer to how an HVAC system uses refrigerant. In 1980, VRV was originally designed and copyrighted by Daikin, the industry leader at that time.For most VRF units, the maximum allowable vertical distance between an outdoor unit and its farthest indoor unit is approximately 150 ft (46 m); the maximum permissible vertical distance between two individual indoor units is approximately 45 ft (14 m); and the maximum actual refrigerant piping lengths allowable ...
