6-2 Energy efficient solution

6-2-5 Low operation sound level

• Continuous research by Daikin into reducing operation sound levels has resulted in the development of a purpose designed inverter scroll compressor

and fan.

• The new grille and fan offer low noise, high volume airflow and are housed in a compact casing together with the associated compressor

components. The use of this new technology assembly enables a 16hp unit to be housed in a single casing.

Aero spiral fan:

Bending the fan blade edge reduces turbulence, resulting in less pressure loss

Aero fitting grille:

New shape promotes spiral discharge airflow, resulting in reduced pressure loss

•Night quiet function (max. -8dBA)

During night time, sound level of the outdoor unit can be reduced for a certain period : starting time and ending time can be input

•Daikin indoor units have very low sound operation levels, down to 25 dBA.
