【文章內(nèi)容簡介】 e the heat load to many cabis, that is to say: move the electronic devices in the over heated cabi to over cabi with low heat load. This methods works, but, there are a lot of labor works for dismantling, assembling and related expenses. More, some time, this methods could not be carried out, because some times, all the ponents or servers must be installed at a same cabi for the needs of management. AIRSYS REFERIGERATION ENGINEERING TECHNOLOGY (BEIJING) CO., LTD. 出現(xiàn)過熱現(xiàn)象時，機(jī)房管理人員會同相關(guān)專業(yè)人員商量。有經(jīng)驗(yàn)的設(shè)計(jì)師、安裝人員在現(xiàn)場考察之后，會推薦這個方案。 應(yīng)該說，這是一種好的方案。調(diào)整空調(diào)機(jī)的位置、調(diào)整氣流分布后，問題可以解決。 優(yōu)化空調(diào)機(jī)的安裝位置 相關(guān)工作和費(fèi)用 : 重新安裝風(fēng)管、水管、制冷劑管路 重新接線、調(diào)試 注意事項(xiàng) : 費(fèi)用仍較高 較長的施工周期 某些時候，此方案不可行。 AIRSYS REFERIGERATION ENGINEERING TECHNOLOGY (BEIJING) CO., LTD. When there exists hot spot, the administrator of DC will consult with air conditioning supplier. The experienced designers, installation peoples will put forward this solution to user after surveying to the data center. It should be confirmed that this is a good solution. The air flow distribution can be improved and the over heat can be eliminated by this method. Works and expenses: Repiping for air duct, water pipe, refrigerant pipes Issues: Higher expenses Long installation engineering duration May not be possible to carry out some times. Optimize the installation position of AC AIRSYS REFERIGERATION ENGINEERING TECHNOLOGY (BEIJING) CO., LTD. Accurate air supply or return 精確送風(fēng)或回風(fēng) This is a very direct solution: ? Make the cold air from AC directly be supplied to the hot position or hot air returned from hot position. Issues and considerations: ? Air pressure of AC should be high enough, if not so, a fan in air duct is needed. (this is the most cases) ? No backup of AC ? High investment ? Need big space for air duct installation 這是一種非常直接的方案 : ? 將冷風(fēng)直接從空調(diào)機(jī)的出風(fēng)口送到過熱位置或者將過熱位置的熱空氣抽走到不過熱位置 注意事項(xiàng) : ? 空調(diào)機(jī)的風(fēng)壓必須足夠，必要時在風(fēng)管上安裝風(fēng)機(jī)（一般都需要） ? 要注意空調(diào)機(jī)有停機(jī)的時候 ? 投資高 ? 風(fēng)管安裝的工作量大，空間占用多 AIRSYS REFERIGERATION ENGINEERING TECHNOLOGY (BEIJING) CO., LTD. Build new machine room 新建機(jī)房 ? This is an extreme way but also popular one. Many unnecessary new machine is built up because of heat problem. ? According to our viewpoint, most of the cases, the new machine room is not necessary to build. Except that there is another big reason besides of hot problem. ? 這是極端的做法，卻也是比較普遍的做法。因?yàn)闊釂栴}而興建了許多不必要的新機(jī)房。 ? 根據(jù)我們的觀點(diǎn)，多數(shù)情況下，這些新機(jī)房是不需要建造的。除非有其它熱點(diǎn)問題之外的大原因。 AIRSYS REFERIGERATION ENGINEERING TECHNOLOGY (BEIJING) CO., LTD.
