3.23.2 Calculating Refrigerant R134a Charge—Example
Using Table 3.14 on the previous page,Table 3.15 on the previous page,Table 3.16 above andTable 3.17
above, 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,
Liebert XDR and Liebert XDV). The example below combines one Liebert XDP with 20 Liebert XDV8
cooling modules.
