随着铁路现代化建设的需要,铁路运营管理自动化电子计算机网络系统势必加速建成。电子计算机房要求设计合适的空调系统,以维持计算机正常工作。本文谈空调机用水问题。空调机的制冷压缩机运转中需要供应具有一定压力、流量的冷却介质(淡水)。例如:LH48型空气调节机用的冷却水量是每小时7.9吨,一般水压要求在1.5～2公斤/平方厘米(表压)。目前,我们单位共装有空调制冷机12台,全部运行每小时需要冷却水约80吨。在夏天炎热季节,用水量达到高峰时,水压更难以达到要
With the needs of railway modernization, the automation and computer network system for railway operation and management is bound to be accelerated. The computer room requires the design of a suitable air conditioning system to keep the computer working properly. This article talks about the water use of air conditioners. In the operation of a refrigeration compressor of an air conditioner, a cooling medium (fresh water) having a certain pressure and flow rate is required to be supplied. For example, the cooling water used by the LH48 air conditioner is 7.9 tons per hour, and the general water pressure is 1.5 to 2 kg/cm2 (gauge pressure). At present, our unit is equipped with a total of 12 air-conditioning refrigerators, and all of them require about 80 tons of cooling water per hour. In the summer hot season, when the water consumption reaches its peak, the water pressure is more difficult to achieve.
