STANDARD PERFORMANCES - IR COOLING UNIT ONLY
Tw= Outlet water temperature °C kWf = Cooling capacity (kW). kWa = Compressor power input (kW)
The standard performances refer to a 5°C temperature difference between the water entering and leaving the heat exchanger and to operation of the unit with all fans at
nominal or maximum speed. A 0.44 x 10

K/W fouling factor has also been considered with the unit installed at zero meters above sea level (Pb = 1013mbar).
The performances are declared no considering any correction due to water flow rate and water side pressure drop (gross performance).
