deltclim CoolWll Greter performnce, lower energy consumption, greter flexibility, lower spce requirement Perfect ir-conditioning for your computer centre The requirements which computer centres need to meet re continully growing. Incresing quntities of dt nd ever expnding cpcities men tht computer rooms need continully-expnding cooling cpcities. This leds to n increse in energy costs nd, frequently, ssocited shortges of spce. The required cooling cpcity is no longer chieved in extreme cses. The deltclim CoolWll from Weiss Klimtechnik GmbH represents n intelligent solution for computer rooms of ll sizes. The flexible, high-output nd energy-sving system is recommended for both new instlltions nd s retrofitting solution. A relible principle The deltclim CoolWll functions in the sme mnner s n ir-conditioning cbinet, with fns for ir conveynce nd het exchnger to cool the ir. Wheres ny ir-conditioner unit cn only exploit the het exchnge surfce in the device itself, the deltclim CoolWll utilises the complete height nd width of the computer room to cool ir. The entire IT room thus becomes n ir cooling unit. Adequte output for every need The considerbly-expnded cooling surfce nd flexible ir flow lyout with fns in the double floor prcticlly doubles the specific cooling cpcity when compred to precision ir-conditioner units. Consequently, the output of the deltclim CoolWll increses flexibly reltive to the growing cooling demnds of computer rooms. This ensures the chievement of much enhnced sclbility when compred to conventionl precision ir-conditioners.

A prcticl investment for your compny Sve energy Cooling of the computer room cn be precisely controlled through the design of the het exchnger nd number of fns. The drstic reduction in internl pressure losses is chieved s consequence, resulting in considerble drop in energy consumption when compred to ir-conditioning cbinets. And the lrger the cooling cpcity required, the greter the sving chieved. [Investment costs re, in ny cse, lower thn the new instlltion of precision ir-conditioner units.] Crete the spce you need The complete dispensing with ir-conditioning cbinets mens tht considerbly more spce is vilble, nd cpcities cn lso be expnded without difficulty in consisting spce concepts. The outly for instlltion of the deltclim CoolWll cn be compred somewht to tht of conventionl ir-conditioner units. The deltclim CoolWll principle The deltclim CoolWll consists of wll with cooling nd filter module encompssing seprte control nd specil energy-sving EC fns. The fns ensure tht the required ir flow is estblished behind the cooling wll. They force nd filter the hot ir out of the computer room through the cooling wll, conveying the cold ir through the double floor bck to the rcks. In the contrry lyout, the ir flow selectively expels hot ir through the double floor nd feeds in cold ir through the cooling wll. The generous het exchnge surfces men tht higher wter tempertures cn lso be employed. This enbles the extended exploittion of externl ir during opertion with indirect free cooling. The deltclim CoolWll cn be integrted without difficulty in the existing cold wter mins network.

deltclim CoolWll Greter performnce, lower energy consumption, greter flexibility, lower spce requirement Flexibility over the entire surfce Perfect for ny room rchitecture The wrm nd cold room concept When it comes to cooling servers, the deltclim CoolWll is vilble in two versions: the wrm room nd cold room concept. The wrm room concept involves the introduction of cooled ir into the double floor nd its conveynce vi the perforted double floor pltes to the rck suction points. The cooling ir flows through the server cbinet t temperture (for exmple) between 20 nd 26 C, bsorbs the het present nd returns to the circuit vi the cooling wll. Air conveynce is reversed in the cold room concept. The ir is fed into the room through the cooling wll nd suctioned into the server. It bsorbs the het present here nd returns to the circuit vi the double floor. At this, the complete room ppers s compenstion room nd the IT stff is working in cooled environment. The deltclim CoolWll not only represents spce-sving solution becuse n ir-conditioning cbinet is no longer required. Its instlltion is lso completely flexible nd, consequently, cn be dpted to suit ny room rchitecture. Different lyouts cn, in principle, be relised in ll conceivble vrints nd dimensions. The cooling surfces of the deltclim CoolWll consist of modulr components in two sizes (2,400 mm x 1,200 mm nd 2,400 mm x 1,800 mm). This mens tht the entire wll surfce of every computer room cn be fitted, regrdless of the room size. Single-sided instlltion The computer room is supplied vi deltclim CoolWll t the end wll. Double-sided instlltion The computer room is supplied vi two deltclim CoolWll t both end wlls. Centrl instlltion Two computer rooms re supplied simultneously vi two deltclim CoolWll seprted from ech other. Corner instlltion A computer room cn lso be supplied by two deltclim CoolWll units locted in the corners if the end wll on its own is too nrrow. 4

Seven precision ir-conditioner units with service ccess nd, lterntively, deltclim CoolWll nd 42 fns in the double floor were instlled long the front wll on n instlltion surfce of 20 m x 2 m in computer room with width of 20 m, length of 50 m nd height of 2.6 m (bove the double floor). The het exchngers re fed with cooling wter with supply temperture of 10 C nd return temperture of 15 C. The ir intke temperture in the het exchngers is 30 C. The cooling cpcity ws clculted with the sme temperture difference for both exmples, while it ws ssumed tht n ir-conditioner unit is instlled for plnt opertion (i.e. only six units were included in the clcultion). The result The lrger het exchnge surfce enbled the deltclim CoolWll to chieve prcticlly twice the specific cooling cpcity in the sme re when compred with conventionl precision ir-conditioner units. The deltclim CoolWll cn dissipte round 1.9 kw per m² re, while the precision ir-conditioner units cn only brely mnge 1 kw. It simultneously sves energy nd considerbly reduces running costs. deltclim CoolWll vrint Specific cpcities dissipted: 1,844 kw/960 m² = 1.92 kw/m² Conventionl circulting cooling unit vrint Specific cpcities dissipted: 936 kw/960 m² = 1 kw/m² 5
