Overview The modular, row-based computer room cooling solutions offers efficient, predictable, and economical cooling for a variety of spaces. Critical environmental requirements now reach far beyond the confines of the traditional data center or computer room to encompass a larger suite of applications, referred to as technology rooms.
PAGE 9
Scalable Solutions for Critical Environments Advantages of row-based cooling InRow cooling products improve energy efficiency and cooling ability in a number of ways. First, the InRow CW air conditioner draws air directly from the hot aisle, allowing the InRow unit to take advantage of higher heat transfer efficiency due to higher temperature differences. It can then discharge room-temperature air directly in front of the servers it is cooling.
PAGE 10
EcoAisle™ Aisle Containment System Modular ceiling tiles and doors/curtains can be used to enclose the hot aisle. This increases the densities that can be handled in a single rack enclosure by eliminating mixing of hot and cold air streams. This method, called load neutralization, removes the heat from the hot aisle, cools it, and then returns it to the surrounding room area.

Configurations Chilled water systems utilize water from a chiller plant for cooling. Chilled water is commonly used in large buildings and high rises and can serve multiple indoor units, which can be cost effective for large installation options. There are various methods for chilled water piping.

Standard Features and Options Standard features Insulated side panels The frame is constructed of 16 gauge formed steel for maximum strength. Cabinet is serviceable from the front and rear. All exterior panels and corner posts on the frame are powder coated for durability and an attractive finish. Front and rear exterior panels are constructed of 18 gauge perforated steel with 84% open free area. Insulation is 80.1 kg/m3 (5 lb/ft3) density and complies with ASTM E84 rating of 25/50.

30% ASHRAE 52.1 filter (ACRC500/ACRP500 series only) The filtration of conditioned air is extremely vital to maintaining the clean, particle-free environment required by electrical equipment. The system uses a 30% efficient, 102 mm (4 in), deep loading, pleated filter. Deeper filters produce a lower pressure drop, requiring less energy during normal operation. The filter is moisture resistant up to a 100% relative humidity. Filters are easily replaceable from the rear of the unit. (MERV 8 per ASHRAE 52.
PAGE 16
Optional features Cable water detector A leak detection cable for 300-mm units (NBES0308 and NBES0309) or 600-mm units (AP9325 and AP9326) is placed on the floor or sub-floor around all possible leak sources. If water or other conductive liquids contact the cable anywhere along its length, the microprocessor controller visually and audibly announces a leak. The 6.1-m (20-ft) cable may be cascaded to make custom lengths up to 24.4 m (80 ft).

85% ASHRAE 52.1 filter (ACRC500/ACRP500 series only) 990-4618C-001 Electrical equipment requires clean, particle free air, thus making the filtration of the air extremely important. Optionally, the system uses an 85% efficient, 102-mm (4-in.), deep loading, pleated filter. Deeper filters produce a lower pressure drop, requiring less energy during normal operation. The 100% synthetic media will not absorb moisture and is resistant to most common chemicals.

Determining Cooling Capacity IT equipment requires two acceptable limits in order for effective cooling to occur. These parameters are inlet air temperature and flow rate of air through the IT equipment. It is entirely possible, though undesirable, to design a computer room with enough heat removal capacity, but with an inadequate volumetric flow rate of cool air supply.
