It can then discharge room temperature air directly in front of the servers it is cooling. This increases energy efficiency by allowing the chiller to operate at higher leaving water temperatures. Placing the cooling unit in the row enables the unit to operate at higher return and supply air temperatures, yielding 100% sensible capacity. This significantly reduces the need for humidification. Scalable for High Density The predictable performance of the row-based architecture makes it well suited for high density applications. The focus on heat removal instead of cold air delivery is the key to making this approach scalable. The modular design of the InRow RP allows it to be easily added in the row as the demand for cooling increases. The additional benefit of the row-based architecture is the ability to add hot aisle containment. Containing the hot aisle further reduces any chance of hot and cold air streams mixing. This provides ultimate predictability and allows the cooling capacity to be matched to the IT heat load. Hot Aisle Containment System Modular ceiling tiles and doors 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 at or slightly below room temperature. The warmer return air temperatures that are achieved in this application increase the capacity of the air conditioner. Use of modular ceiling tiles across a 914.4 mm (3 ft) hot aisle that connects two opposite rack enclosures makes expansion quick and simple. Expansion kits, with necessary ceiling tile and all baying hardware, can be ordered to increase the size of the hot aisle by one rack on each side. The end doors can be easily removed and re-attached for expansion. The enclosed hot aisle prevents any warm return air from mixing with cold supply air. In effect, all surrounding room air can act as supply air to the system. The hot aisle containment system is beneficial in any environment. It can be deployed quickly in any controlled space without expensive additions to the infrastructure, such as raised floor or ductwork. na2763b 1798.58 (70.81) 3037.80 (119.60) ) ( ) 874.52 34.43 NetShelter NetShelter PDU UPS InRow NetShelter NetShelter na2762d ( ) 1155.70 45.50 ( ) 990.60 39.00 InRow NetShelter NetShelter 1325.88 52.20() PDU PDU ( 1331.72 52.43 600 600 600 600 600 600 (23.62) (23.62) (23.62) (23.62) (23.62) (23.62) Dimensions are shown in mm (in). InRow RP Technical Data Manual Standard Features Insulated Cabinet The frame is constructed of 1.5 mm (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 panel are constructed of 1.2 mm (18 gauge) perforated steel with 69.5% open free area. Insulation is 80.1 kg/m3 (5 lb/ft3) density and complies with ASTM E84 rating of 25/50. All panels include a key latch for safety and security for easy access and removal. Variable Speed Fans The InRow RP unit is equipped with variable speed, electrically commutated, 400 mm (15.8-in) backward incline, direct drive fans. The chilled water unit is equipped with three fans while the air-cooled unit has two. In order to provide uniform airflow over the cooling coil, the fans provide a draw-through air pattern. Fans are easily serviced in the field. Shutdown Input/Alarm Output The unit provides one field connection input for remote shutdown and one field connection alarm output. Chilled Water Flow Meter Internal piping of the unit includes a flow meter wired into the microprocessor controller to display chilled water flow and determine operating performance. 2-way/3-way Floating PointValve (CW Only) A floating point valve is microprocessor controlled to regulate the amount of chilled water into the cooling coil to maintain desired conditions. The standard valve pressure rating is 4136.8 kPa (600 psig). The maximum operation pressure of the unit is 2068.4 kPa (300 psig). The valve is user configurable to be two-way or three- way. Counterflow Cooling Coil/ Condensate Pan Designed for high sensible heat ratios, the coil is constructed with copper tubes, raised lance type aluminum fins, and 1.2 mm (18 gauge) galvanized steel end plates. Coil headers are equipped with anti drip shields in case of condensation. Condensate pan is UL94 V-0 thermal formed non-ferrous material sloped for positive drainage for higher indoor air quality. Electric Reheat Electric reheat elements are low watt density, wired for three-phase and loaded equally on all three phases, and electrically and thermally protected by both automatic and manual reset thermal cut outs. Reheat elements are stainless steel, fin tubular construction. 30% ASHRAE 52.1 Filter The filtration of cond...
