Deltaclima CoolWall - Cooling and Filter Module - Brochure

Weiss Klimatechnik GmbHPassion for Climatedeltaclima CoolWall®We provide you with the perfect air-conditioning solution for your computer centre WKT-E 0/11 0,5M 12/10 N Glo BecThe requirements which computer centres need to meet are conti-nually growing. Increasing quan-tities of data and ever expanding capacities mean that computer rooms need continually-expanding cooling capacities. This leads to an increase in energy costs and, frequently, associated shortages of space. The required cooling capacity is no longer achieved in extreme cases.The deltaclima CoolWall® from Weiss Klimatechnik GmbH represents an intelligent solution for computer rooms of all sizes. The flexible, high-output and energy-saving system is recommen-ded for both new installations and as a retrofitting solution.A reliable principleThe deltaclima CoolWall® functions in the same manner as an air-conditioning cabinet, with fans for air conveyance and a heat exchanger to cool the air. Whereas any air-conditioner unit can only exploit the heat exchange surface in the device itself, the deltaclima CoolWall® utilises the complete height and width of the computer room to cool air. The entire IT room thus becomes an air cooling unit.Adequate output for every needThe considerably-expanded cooling surface and flexible air flow layout with fans in the double floor practically doubles the specific cooling capacity when compared to precision air-conditioner units. Consequently, the output of the deltaclima CoolWall® increases flexibly relative to the growing cooling demands of computer rooms. This ensures the achievement of much enhanced scalability when compared to conventional precision air-conditioners.Perfect air-conditioning for your computer centredeltaclima CoolWall® Greater performance, lower energy consumption, greater flexibility, lower space requirementCriteria deltaclima® deltaclima CoolWall®Cooling capacity > 300kW aLow space aCold chamber concept aInnovative system aMicro scalability aThe deltaclima CoolWall®? Extremely high cooling capacity? Extremely low energy requirement? Extremely space-saving? Extremely-flexible room layout? Extremely favourable scalability ? Extremely investment-friendlySave energyCooling of the computer room can be precisely controlled through the design of the heat exchanger and number of fans. The drastic reduction in internal pressure losses is achieved as a consequence, resulting in a considerable drop in energy consumption when compared to air-conditioning cabinets. And the larger the cooling capacity required, the greater the saving achieved. [Investment costs are, in any case, lower than the new installation of precision air-conditioner units.]Create the space you needThe complete dispensing with air-conditioning cabinets means that considerably more space is available, and capacities can also be expanded without difficulty in consisting space concepts. The outlay for installation of the deltaclima CoolWall® can be compared some-what to that of conventional air-conditioner units.A practical investment for your companyThe deltaclima CoolWall® principleThe deltaclima CoolWall® consists of a wall with a cooling and filter module encompassing a separate control and special energy-saving EC fans. The fans ensure that the required air flow is established behind the cooling wall. They force and filter the hot air out of the computer room through the cooling wall, conveying the cold air through the double floor back to the racks. In the contrary layout, the air flow selectively expels hot air through the double floor – and feeds in cold air through the cooling wall.The generous heat exchange surfaces mean that higher water temperatures can also be employed. This enables the extended exploitation of external air during operation with indirect free cooling.The deltaclima CoolWall® can be integrated without difficulty in the existing cold water mains network.3deltaclima CoolWall® Greater performance, lower energy consumption, greater flexibility, lower space requirementFlexibility over the entire surface Perfect for any room architectureSingle-sided installationThe computer room is supplied via a deltaclima CoolWall®at the end wall.Double-sided installationThe computer room is supplied via two deltaclima CoolWall®at both end walls.Central installationTwo computer rooms are supplied simultaneously via two deltaclima CoolWall® separated from each other.Corner installationA computer room can also be supplied by two deltaclima CoolWall® units located in the corners if the end wall on its own is too narrow.The warm and cold room conceptWhen it comes to cooling servers, the deltaclima CoolWall® is available in two versions: the warm room and cold room concept. The warm room concept involves the introduction of cooled air into the double floor and its conveyance via the perforated double floor plates to the rack suction points. The cooling air flows through the server cabinet at a temperature (for example) between 20 and 26 °C, absorbs the heat present and returns to the circuit via the cooling wall. Air conveyance is reversed in the cold room concept. The air is fed into the room through the cooling wall and suctioned into the server. It absorbs the heat present here and returns to the circuit via the double floor.At this, the complete room appears as „compensation room” and the IT staff is working in cooled environment.The deltaclima CoolWall® not only represents a space-saving solution because an air-conditioning cabinet is no longer required. Its installation is also completely flexible and, consequently, can be adapted to suit any room architecture. Different layouts can, in principle, be realised in all conceivable variants and dimensions.The cooling surfaces of the deltaclima CoolWall® consist of modular components in two sizes (2,400 mm x 1,200 mm and 2,400 mm x 1,800 mm). This means that the entire wall surface of every computer room can be fitted, regardless of the room size.4deltaclima CoolWall® Greater performance, lower energy consumption, greater flexibility, lower space requirementPerfect for any room architecture Same area, twice the capacityConventional circulating air cooling unitdeltaclima CoolWall®Temperature air intake 30°C / 30 % r.h. 30°C / 30 % r.h.Cooling water temperature 10°C /15°C 10°C /15°CCooling capacities 6 x 156 kW = 936 kW 1,844 kWHeat exchange surface 6 x 3.84 m² = 23 m² 2.5 x 18 m² = 45 m²Fans 18 x 42 xAir output at same air speed 6 x 33,000 m³/h = 198,000 m³/h 390,000 m³/hComputer room area 48 x 20 m = 960 m² 48 x 20 m = 960 m²Specific cooling capacity 0.98 kW/m² 1.92 kW/m²SYSTEM COMPARISONdeltaclima CoolWall® and circulating cooling unit An exemplary calculation based on a computer room with an area of 960 m² was made to compare the performance of precision air-conditioner units with the deltaclima CoolWall®. Seven precision air-conditioner units with service access and, alternatively, a deltaclima CoolWall® and 42 fans in the double floor were installed along the front wall on an installation surface of 20 m x 2 m in a computer room with a width of 20 m, a length of 50 m and a height of 2.6 m (above the double floor). The heat exchangers are fed with cooling water with a supply temperature of 10 °C and a return temperature of 15 °C. The air intake temperature in the heat exchangers is 30 °C. The cooling capacity was calculated with the same temperature difference for both examples, while it was assumed that an air-conditioner unit is installed for plant operation (i.e. only six units were included in the calculation). The resultThe larger heat exchange surface enabled the deltacli-ma CoolWall® to achieve practically twice the specific cooling capacity in the same area when compared with conventional precision air-conditioner units. The deltaclima CoolWall® can dissipate around 1.9 kW per m² area, while the precision air-conditioner units can only barely manage 1 kW. It simultaneously saves energy and considerably reduces running costs.5deltaclima CoolWall® Greater performance, lower energy consumption, greater flexibility, lower space requirementdeltaclima CoolWall® variantSpecific capacities dissipated: 1,844 kW/960 m² = 1.92 kW/m²Conventional circulating cooling unit variantSpecific capacities dissipated: 936 kW/960 m² = 1 kW/m²Housing ?
