, reverberation time t=05s directivity factor Q=2,
distance r=2.5m
Cooling:
• Room air temperature 27°C D.B.; 19°C W.B.
• Water inlet temperature 7°C; water Dt 5°K
Heating 50°C:
• Environmental air temperature 20°C
• Inlet water temperature: 50°C ; water Dt 10°K
Heating 70°C:
• Environmental air temperature 20°C
• Inlet water temperature: 50°C ; water Dt 10°K
The earth leakage current of several devices
placed under the same circuit breaker is
summed, therefore we recommend paying
attention to the calibration value of the
circuit breaker and, if necessary, consider
splitting the installation in more circuits, each
of which protected by its own circuit breaker.
