(1)
: Minimum water volume standard thermostat difference setting of 3 K. For reduced setting multiply
this water volume by (3/new setting). Minimum allowable setting = 0.1 K.
(2)
: The sound pressure level is measured using a microphone at a certain distance from the unit. It is
a relative value, depending on the distance and acoustic environment.
(3)
: The sound power level is an absolute value indicating the “power”, which a sound source
generates.
Nominal conditions The nominal conditions are as follows:
■ entering/leaving chilled water temperature 12/7 °C, ambient air temperature 35 °C
■ entering/leaving condenser water temperature 45/50 °C; ambient 7 °CDB/6 °CWB
■ power input is total input: compressor + control circuit
■ sound pressure level is measured at a height of 1.5 m and a distance of 1 m in front of the unit.
Operation range The operation range contains:
■ a leaving evaporator water temperature from 4 °C till 20 °C (pull-down condition till 25 °C)
■ a leaving condenser water temperature from 35 °C till 55 °C.
