    tmbh
    t = Total Load
    mbh = 1000 btu/hr

    smbh
    s = Sensible Load
    mbh = 1000 btu/hr

    Hello Quantum : thanks for that explanation !

    (tmbh : t = Total Load , mbh = 1000 btu/hr , and smbh : s = Sensible Load , mbh = 1000 btu/hr).

    With hvac most probably meaning 'High Voltage AC' , are we perhaps talking here of the selection parameters for some heating or cooling application that has to run on 220/240 Volt AC or higher voltages ?

    Hello All

    HVAC means Heating, Ventilation, Air Conditioning

    To select AHU or FCU the least parameters required are

    Option 1
    Tmbh, smbh, air on coil conditions, air flow, external static pressure


    Option 2
    Tmbh, air on coil conditions, air off coil condition, air flow, external static pressure
