3.6.1 Calculating Refrigerant Charge—Example
Using Tables 6, 7, 8 and 9, calculate the refrigerant charge of the individual sections of your Liebert
XD system. Add the calculated charge amounts to determine the amount of R-134a refrigerant
required for one system combining a Liebert XDP with Liebert XD cooling modules (Liebert XDCF,
Liebert XDH, Liebert XDO and Liebert XDV). The example below combines one Liebert XDP with 20
Liebert XDV8 cooling modules.
