*1 - Sensible heat is energy carried by air particles
*2 - Latent heat is energy carried by the moisture in the air
*3 - Operating sound is measured in anechoic chamber 1.5m below the centre of the unit.
Sound level is about 8dBA higher at unit air discharge port.
Test conditions: Indoor : 20°Cdb / 50%RH (Winter), 27°Cdb / 60%RH (Summer) Outdoor : 7°Cdb / 70%RH (Winter), 35°Cdb / 60%RH (Summer)
