Notes Nominal cooling capacities are based on : indoor temperature : 27°CDB, 19°CWB, outdoor temperature : 35°CDB,
equivalent refrigerant piping : 7.5m, level difference : 0m.
Nominal heating capacities are based on : indoor temperature : 20°CDB, outdoor temperature : 7°CDB, 6°CWB,
equivalent refrigerant piping : 7.5m, level difference : 0m
Sound levels are measured in an anechoic room
Sound pressure level is a relative value, depending on the distance and acoustic environment. For more details,
please refer tosound level drawings of this chapter.
The sound power level is an absolute value indicating the power which a sound source generates.
