

Heat exchanger

Improved performance by subcooling circuit

The system performance is improved by enlarged heat transfer area of FS(V)N(Y)2E unit and subcooler heat exchanger.

A: Rear side.

B: Front side.

C: Sub-cooler.

D: Air inlet.

E: Air outlet.

F: Increase of enthalpy due to the use of the sub-cooling circuit.



Fan unit

Super high-stream fan

The outdoor units have been designed with a new super high-stream fan of Ø544 mm, reducing the sound level and in-

creasing its reliability, by the use of a three-blade design propeller.

This fan is much more aerodynamic than earlier models. It has a greater surface area in contact with the air and a better

turning angle, preventing turbulence and allowing the ventilator to be tted lower.

Additionally, the rib structure synchronized with rotation ow from the fan reduces the air resistance at the air outlet grille.

A: Optimized distribution at air outlet angle.

B: Optimized distribution at air inlet angle.

C: Increased angular advance.

Side ow technology

Energy-saving and uniform air velocity distribution by side ow technology.

A: Air inlet.

B: Air outlet.

C: Air speed (m/s).
