Precision vs. Comfort Cooling
In small or remote facilities, the careful consideration of equipment essential to reliable operation is a step frequently overlooked in favor of other aspects of the planning process. As a result, areas such as environmental control, power continuity and monitoring of critical computer support systems often receive far less attention than decisions about servers, operating systems and other network-level components that make up a critical IT infrastructure. However, achieving business-critical continuity is as dependent on power and environmental support systems as on advanced networking equipment. The high sensitivity of electronic components in data center and networking environments means that temperature, humidity, air movement and air cleanliness must be kept consistent and within specific limits to prevent premature equipment failures and costly downtime. Comfort cooling systems — including room air conditioners, residential central air conditioners and air conditioning systems for office and commercial buildings — are occasionally used in these applications. This is usually because the differences between comfort and precision cooling systems can be ambiguous. Comfort cooling systems are engineered primarily for the intermittent use required to maintain a comfortable environment for people in facilities with a moderate amount of in-and-out traffic. However, while these systems are capable of effectively maintaining acceptable conditions for human occupants, they are not designed to regulate humidity
Precision cooling systems, on the other hand, are engineered primarily for facilities that require year-round constant cooling, precise humidity control and a higher cooling capacity per square foot. This type of environmental conditioning can utilize a wide range of cooling mediums, including air, chilled water and pumped refrigerants. To further elaborate, a number of factors should be taken into consideration when comparing precision and comfort cooling systems.
Precision cooling is an air conditioning or cooling technique that is specifically designed for use in IT equipment and environments and is implemented in devices that directly cool electronic and IT equipment. It has better air filtration capabilities, higher air flow and advanced humidity control mechanisms than standard cooling techniques.
Precision cooling helps beneficially control and manage air flow for indoor IT devices and equipments. Typically, a precision cooling system can be managed through software or programmatic access.
Precision cooling allows IT managers to control the temperature, humidity and air flow in an IT environment. Besides environmental and device cooling, precision cooling also assists in removing internal heat generated from computers and equipment. A precision cooling system vents out all the heat to maintain a balanced, sensible heat ratio, such as dynamically adjusted cooling in relation to the heat in or temperature of the device/environment.
