Variable Refrigerant Flow
Preliminary Technology Assessment
What is This Technology?
Variable refrigerant flow (VRF) systems were invented in Japan more than 20 years ago, but new to the American market. VRF uses refrigerant as the cooling / heating medium, and allows one outdoor condensing unit to be connected to multiple indoor evaporators, each individually controllable by its user, while modulating the amount of refrigerant being sent to each evaporator.
