This noise of the product is the value which was measured at the acoustic room. Actually, in the established condition, that undergo influence
by the echoing of the room and so that become bigger than the display numerical value .
PERFORMANCE
Use conditions
Outdoor air conditions
Temperature range -10˚C ~ 40˚C
Relative humidity 85% or less
Indoor air conditions
Temperature range -10˚C ~ 40˚C
Relative humidity 85% or less
Installation requirements
Same as the indoor air conditions
* Indoor air here means air in air-conditioned
living rooms.
Its use in refrigerators or other places
where temperature can fluctuate greatly is
prohibited even if a temperature range is
acceptable.
Example Indoor air conditions
During cooling period
Temperature 27˚C
Relative humidity 50%
During heating period
Temperature 20˚C
Relative humidity 40%
• The Input, the current and the exchange
efficiency are values at the time of the
mentioned air volume.
• The noise level shall be measured 1.5m
below the center of the unit.
• The temperature exchange efficiency
averages that of when cooling and when
heating.
