8.5.2.3. Dimensioning the compressed air receiver


<BR>The volume of the compressed air receiver for screw compressors is calculated with the aid of the following formula. The usual sizes of standard compressed air receivers should be taken into account.

Fig. 8.10: Compressor and compressed air receiver


    VR = Volume of compressed air receiver [m³]
    = FAD of all compressors [m³/min]

    L    B = Required FAD [m³/min]

    Al = Allowed motor cycle rate [1/h]

    pmax = Cut-out pressure of compressor [barü]

    pmin = Cut-in pressure of compressor [barü]
The volume of the compressed air receiver can also be defined according to the BOGE recommendation, compressor FAD to volume of compressed air receiver VR = /3.
