VRF stands for variable refrigerant flow, which goes a surprisingly long way toward describing how this system uses refrigerant for both air conditioning and heating. In a nutshell, VRF is a ductless, large-scale system for HVAC that performs at a high capacity.

Unlike Split Ac, VRF allows multiple indoor units to run on the same system, which is designed differently depending on the application. VRF systems are considered either a heat pump system or a heat recovery system, which can heat and cool simultaneously.
