Variable Refrigerant Flow Systems (VRF) is often referred as “Rolls Royce” of air conditioning systems. This is a very sophisticated system which was invented by Daikin Industries in early 1980s. A typical VRF system comprises of an outdoor unit that may contain one or multiple compressors. The outdoor unit is connected to several indoor units or air handlers through refrigerant piping. The refrigerant flows from the outdoor unit to the air handlers to cool the room air. But the system can control the amount of refrigerant flowing to the multiple evaporators (indoor units). It can also control the output of the compressor according to overll demand of the indoor units.
