What is VRF?


When explaining what a VRF system is and how it operates…complexity is the name of the game when describing the technical nature of how Variable Refrigerant Flow technology works.


VRFs are typically installed with an inverter which adds a DC inverter to the compressor in order to support variable motor speeds and thus variable refrigerant flow, while manipulating AC, DC, 1 Phase and 3 Phase electricity. By operating at varying speeds and only at the needed rate allowing for substantially lower energy at load conditions……Wait! Stop the madness!!


…the simplest explanation of VRF is to describe it as a large-scale ductless HVAC system “on steroids” that can perform at a high capacity. The specific design of a VRF system varies, based on application. In general, VRF technology provides the ability for multiple indoor units or zones to operate on the same system. VRF systems can either be a heat pump system or a heat recovery system, which provides simultaneous heating and cooling.


VRF is known for its superior energy efficiency and ability to offer a quick return on investment in many applications.


Because of this versatility, VRF products can be customized to meet the specific demands of virtually any residential or commercial project and deliver a state-of-the-art HVAC solution.
