4. PERFORMANCES
In order to define the performances of IWCi subject to conditions different from rated conditions, a computer program for the correct choice of the
units is provided by Galletti SpA.
With a few input data it will be possible to get information on the behaviour of an IWCi referring to the desired operating conditions.
It will be sufficient to enter the following data:
• Dry bulb inlet air temperature
• Wet bulb inlet air temperature or alternatively the relative humidity
• Inlet water temperature
• Outlet water temperature or alternatively the water flow
• Ethylene glycol percentage (default 0)
• Fan speed
• Available static head (default 0) and air flow rate (≠0)
• Directivity factor and distance
Output data
• Selected full scale (850-1450 RPM)
• Control voltage
• Total cooling / heating capacity
• Sensible cooling capacity
• Water flow
• Pressure drop, water side
• Outlet air temperature
• Sound power level
• Sound pressure level under the specified conditions
• Power input
The selection report generated by the software includes the drawing with overall dimensions and description of the unit.
