TAILIEUCHUNG - The Different Types of Air Conditioning Equipment for IT Environments

Exceptions to the recommended criteria may arise in various circumstances. These include cases where equipment has to be assessed that when installed was compliant with safety and performance standards that predate the criteria/suspension levels presented here. In such cases, the equipment must be reassessed according to the criteria of this report including the risk assessment. Following that, the MPE must make a recommendation to the holder. These recommendations must take a balanced view of the overall situation, including the economic/social circumstances, older technology etc, and the purpose for which the equipment is deployed. It is possible that the MPE. | By Tony Evans White Paper 59 Legendary Reliability The Different Types of Air Conditioning Equipment for IT Environments Executive Summary Cooling equipment for an IT environment can be implemented in 10 basic configurations. The selection of the appropriate configuration for a particular installation is affected by the existing facility infrastructure the total power level of the installation the geographical location and the physical constraints of the building. This document describes the 5 fundamental cooling transport methods that combine with 2 fundamental physical arrangements to give rise to the 10 basic configurations. A method for selection of the appropriate configuration for a particular installation is described. The information in this paper allows IT professionals to be more involved in the specification of precision cooling solutions that better align with IT objectives. 2004 American Power Conversion.

Rev 2004-0 2 Introduction Data Center and IT room heat removal is one of the most essential yet least understood of all critical IT environment processes. As the latest computing equipment becomes smaller and uses the same or even more electricity than the equipment it replaced more heat is being generated in data centers. Precision cooling and heat rejection equipment is used to collect and transport this unwanted heat energy to the outside atmosphere. This paper describes equipment that produces cool air removes heat . It explains the different components and cooling methodologies designed to transport heat energy from the IT environment to the outside atmosphere. It provides information describing the best configurations for different IT environments and common practices and equipment options that may increase cooling system availability and
