Based on Eurovent rating standards:
Cooling: Entering/leaving air temperature = 27°C db/19°C wb – entering/leaving water temperature = 7°C/12°C.
Heating (2 pipes): Entering air temperature = 20°C – entering water temperature = 50°C, same water flow rate as in cooling.
Heating (4 pipes): Entering air temperature = 20°C – entering/leaving water temperature = 70°C/60°C.
*
Based on a hypothetical acoustic attenuation for the room and the air distribution system of -21 dB(A).
