The data are measured under the following conditions(ISO-T1).
Cooling: Indoor temp. of 27°CDB, 19oCWB, and outdoor temp. of 35°CDB.
Heating: Indoor temp. of 20°CDB, and outdoor temp. of 7°CDB, 6°CWB.
External static pressure of indoor unit is 10Pa.
The sound level indicates the value of rear-intake type with duct in anechoic chamber. During operation these values are somewhat higher due to ambient conditions.
The data of nominal cooling and heating capacity and sound pressure level are measured with 10Pa of external static pressure.
Sound pressure levels are values when 2m supply duct and 1m return duct are connected.
1 : Mike position is 1.5m below unit, 2 : Mike position is 1m in front and 1m below the air supply duct.
