3.1.1 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.
