3.5 Mechanical System

Air conditioning

Since natural ventilation with the exception of a few mechanical rooms is

not sufficient for a Data Centre, most areas within the facility will have to be

equipped with some kind of mechanical system: Air conditioning,

ventilation or heating. Almost all spaces in the Data Centre require cooling

throughout the year because of outside temperatures during most of the

year and the exhaust heat produced by computer and technical equipment.

Only administrative, mechanical and electrical support areas require minor

heating. The IT-equipment generates a large amount of radiant heat. The

equipment operates most effectively in a relatively narrow temperature and

humidity range.

Environmental parameters are:



Environmental Factor Recommended range

Temperature

68℉ to 77℉

20℃ to 25℃

Relative humidity 40% to 55% RH

The rows of cabinets/racks should be set up parallel to the airflow. The

orientation and arrangement of the rack rows in the computer rooms will

follow up-to-date technical standards (hot aisles, cold aisles layout).

All the data Centers (National, Federal, and regional Data Centers) require

Provision of air conditioning. Package A/C units of split system is

recommended for the data center.

Introduction

1. Air conditioning is to provide a temperature-controlled environment within

the parameters needed to run these devices. Computer and networking

equipment is designed to operate within a fairly narrow temperature range.

To ensure reliable operation and the longest possible life sufficient air

conditioning equipment should be installed to achieve this functional
