Sound level is measured at 1.5m below the center of the body. 
Air flow rate can be changed over to Low mode or High mode.
Sound level is measured in an anechoic chamber.
Sound level generally become greater than this value depending on the operating conditions, reflected sound, and peripheral noise.
The sound level at the air discharge port is about 8 dB higher than the unit's sound level.
Even when the outdoor temperature is below -15°C, the system is operable down to -20°C with the preheater installed at the outdoor air intake side.

Daikin's HRV (Heat Reclaim Ventilation) recovers heat energy lost through ventilation and holds down room temperature changes
caused by ventilation, thereby maintaining a comfortable and clean environment. This also curbs the load on the air conditioning system
and conserves energy. In addition, the HRV is interlocked to Daikin's VRV system, SkyAir and other air conditioning systems and
automatically switches over ventilation mode, further increasing the effects of energy conservation. HRV operation has been centralized
on the air conditioner remote controller allowing total control over air conditioning and ventilation with a simple configuration.

285 mm
Air Conditioning Load 
Reduced by Approximately 28%
1. Approximately 20% by operating
in total heat exchange mode (in
comparison with normal
ventilation fans)
2. Another approximately 6%
gained by auto-ventilation mode
changeover switching 
3. Yet another approximately 2% by
pre-cool, pre-heat control
The use of the originally developed High
Efficiency Paper (HEP) element and
optimized design of the fan and airflow
passages, has enabled the first-class
compactness in the industry while
maintaining some 28% reduction of air
conditioning load as before. The height
of the main unit has been reduced by up
to 285 mm* and easily fits in limited
spaces, such as behind ceilings.
HRV
Operation range of outdoor
temperatures
Cold climate compatible :
Standard operation at
temperatures down to -15°C
The new intermittent
operation mode is
activated when
outdoor temperature
goes down to -10°C
or below, preventing
freezing or
condensation in the
unit. Standard
models can now be
used in cold climate
regions.
