Starting a New Equipment Cooling Project

2.0STARTING A NEW EQUIPMENT COOLING PROJECT

2.1Determining Cooling Equipment Needs

1.Is adequate space available for a Liebert XD installation?

2.Is the hot aisle/cold aisle approach being utilized for this room design or can it be utilized in this room design?

3.Is redundant cooling equipment required?

4.Are there access considerations for all components (possible rigging problems)

5.What heat load growth is anticipated over the next few years?

6.How are the cabinets going to be populated (density of heat generation)?

7.What monitoring requirements are desired or needed?

8.Who will be involved in this project (stakeholders)?

9.Is there existing computer room environmental cooling systems for humidity control and filtration?

10.Is the vapor barrier sufficient?

11.Is a chilled water system available?

a.What is the system’s capacity?

b.What is the system’s chilled water supply temperature?

c.Does the chilled water supply temperature vary during the year or is the temperature constant?

12.How much power is available for cooling equipment?

13.What is the maximum distance between the Liebert XDP/Liebert XDC unit and the farthest Liebert XD cooling module in the proposed layout?

14.If an air cooled Liebert XDC is used – is an area available for the remote condenser?
