General site preparation guidelines 9
Air cooled package unit with remote air cooled chilling plant
•
Chilled water package unit with remote chilled water plant
•
o A redundant air conditioning system
o Sufficient extra cooling capacity to ensure availability of the computer equipment if a partial air conditioning system failure occurs
• Provide space and facilities for future system expansion.
• Specify air conditioning equipment air filters with a minimum rating of 45 percent (based on ASHRAE Standard 52-76, Dust Spot Efficiency Test).
Air conditioning system types
HP recommends the following air conditioning system types:
Design the air conditioning system for 24-hour-a-day,365-day-a-year operation. Provide an air conditioning system that is independent of other systems in the building. Provide one of the following:
•
•
•
• System controls adequate to monitor and maintain the computer room within specified operating ranges
Lighting and personnel heat loads must also be included when calculating the total heat load for the computer room. For example, a person dissipates about 450 BTU/h while performing a typical computer room task.
Air conditioning system guidelines
HP recommends the following guidelines when designing a computer room air conditioning system and selecting the necessary equipment:
Air distribution
•
Humidity control
•
Temperature control
•
Air filtration
•
• Ensure a minimum of 457 mm (18 in) or local code minimum clearance, whichever is larger, from the top of the rack to the fire sprinkler heads.
Cooling requirements
Air conditioning equipment requirements and recommendations are described in the following sections.
Basic air conditioning equipment requirements
The cooling capacity of the installed air conditioning equipment for the computer room should be sufficient to offset the computer equipment dissipation loads, as well as any space envelope heat gain. This equipment should include the following:
Ensure that all ceiling tiles are in place.
