Sound levels refer to units with full load under nominal test conditions.
The sound pressure level refers to a distance of 1m from the outer surface of the unit operating in an open field.
Noise levels are determined using the tensiometric method (UNI EN ISO 9614-2)
Data referred to the following conditions:
utility side exchanger water inlet/outlet 12/7°C
source side exchanger water inlet/outlet 30/35℃
13.4 Admissible water flow rates
Min. (Qmin) and max. (Qmax) water flow-rates admissibles for the correct unit operation.
