[64] [65] [66] In 1969, the first mini-split air conditioner was sold in the US. [67] Multi-zone ductless systems were invented by Daikin in 1973, and variable refrigerant flow systems (which can be thought of as larger multi-split systems) were also invented by
Variable refrigerant flow (VRF), also known as variable refrigerant volume (VRV), is an HVAC technology invented by Daikin Industries, Ltd. in 1982. [1] Similar to ductless mini-split systems, VRFs use refrigerant as the primary cooling and heating medium, and are usually less complex than conventional chiller-based systems.
Split systems are used where ductwork is not feasible or where the space conditioning efficiency is of prime concern. [33] The benefits of ductless air conditioning systems include easy installation, no ductwork, greater zonal control, flexibility of control, and quiet operation. [ 34 ]
Zone control (single zone or multi zone air handlers) Fan location (draw-through or blow-through) Direction of outlet air flow (front, up, or down) Package model (horizontal or vertical) But, the first method is very usual in HVAC market. In fact, most of the company advertise their products by air handling unit applications: Normal; Hygienic

While single-zone constant air volume systems typically do not have these, multi-zone systems often have terminal units in the branch ducts. Usually there is one terminal unit per thermal zone. Some types of terminal units are VAV boxes (single or dual duct), fan-powered mixing boxes (in parallel or series arrangement), and induction terminal ...
