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.
