Designing a Liebert XD Solution

3.16 Determining Refrigerant Volume

After the preliminary system design is completed,

Tables 7

, through

may be used to determine

the amount of refrigerant required. Perform the calculation below for each Liebert XD system being

configured.

3.16.1 Liebert XDP/Liebert XDC Pumped R-134a Circuit Volume

NOTE

All lengths in

Tables 7

and

are actual pipe lengths, not equivalent pipe lengths.

NOTE

System refrigerant volume calculations in

Tables 7

and

are based on a fully loaded

system. Additional charge may be required for lightly loaded systems.
