Example
Continuing the preceding data center example (in
Calculate the Heat Load to be Handled by Liebert XD
on page 21) of a server room 2000 ft2 with 30 racks (15 producing 20kW of heat per rack and 15
producing 10 kW of heat per rack), the three Liebert XDPs required can supply coolant to various types of
Liebert XD modules. For instance, the racks with 20kW per rack could be cooled with either Liebert
XDH20, Liebert XDO20 or Liebert XDR20. The racks with 10kW per rack could be cooled using the Liebert
XDV10.
1. For the 15 racks with 20kW of heat each, the total load is:
15 racks x 20kW per rack = 300kW
The perimeter cooling will address the first 2-5kW per rack:
2kW x 15 racks = 30kW
The Liebert XD solution would have to remove 270kW for these racks with higher heat load.
300kW - 30kW = 270kW

2. For the 15 racks with 10kW of heat each, the total load is:
15 racks x 10kW per rack = 150kW
The base cooling will address the first 2-5kW/rack:
2kW x 15 racks = 30kW
The Liebert XD solution would have to remove 120kW for these racks with a higher heat load.
150kW - 30kW = 120kW

•
12 Liebert XDV10s
and any of the following:
•
13 Liebert XDH20s
•
12 Liebert XDO20s
•
15 Liebert XDR20s
