Hot Aisle Containment Inrow Cooling

The short distance ensures that the air conditioner and its cooling coil receive the exhaust air at its warmest point.

Hot aisle containment inrow cooling. Within hot aisle containment the in row air conditioner immediately captures exhaust air from the server cabinet conditions it and returns it to the hot aisle. In a typical data center only 30 of the conditioned air actually gets to where it s needed. In its simplest form hot aisle containment hac consists of a barrier that guides hot aisle exhaust airflow upward back to the crac computer room air conditioner return. A typical data center uses 2 1 2 x more cooling than necessary and frequently still has hot spots.

The goal of a hot aisle cold aisle containment configuration is to conserve energy and lower cooling costs by managing air flow. While both hot aisle and cold aisle containment strategies offer energy savings this paper concludes that hot aisle containment can provide 40 cooling system energy savings over cold aisle containment due mainly to increased economizer hours. Using containment to aid in data center airflow management can cut energy costs. Hot aisle cold aisle is a layout design for server racks and other computing equipment in a data center.

It also concludes that hot aisle containment should always be used for new data. Hot and cold air containment systems designed to maximize cooling predictability capacity and efficiency at the rack row or room level. The ecoaisle is an intelligent thermal containment solution designed to increase cooling system efficiency while protecting critical it equipment and personnel. Containment refers to a specific layout design for server racks and other computing equipment in a data center.

The hot air is collected from the hot aisle pulled through the heat exchange coil and the cooled air is then exhausted into the cold aisle dcr in row cooling dcr s in row cooler irc is available in three configurations maximizing the performance consistent with the site infrastructure. Cold aisle containment combined with inrow cooling can cool more than 30kw heat load per rack. This method keeps hot exhaust air emitted from server racks separated. Data center containment solutions.

Hot aisle containment or hac uses a physical barrier to force hot exhaust airflow back to the ac return while cold aisle containment or cac eliminates hot spots and while creating a uniform temperature for optimal operating efficiency.
