Variable Refrigerant Volume (VRV) and Variable Refrigerant Flow (VRF) are large-scale HVAC systems that require less materials and time to install than other systems yet they provide extensive climate control capabilities and operate at high levels of capacity.
Invented by Daikin 30 years ago, VRV and VRF Heat Pump Systems can provide heating or cooling to an entire building at any time. Alongside their huge capacity, these systems are also extremely quiet and are very easy to install as the materials involved weigh much less than other HVAC materials.
