程控机房空调冬季制冷方案节能分析 【摘要】 利用DeST软件对某一程控机房建筑模型全年空调负荷进行动态分析,分析了程控机房的冬季仍需要制冷的特殊空调要求及其全年空调动态负荷,介绍了直接利用新风的机房专用空调系统、冷却塔供冷、REFNAC式机房专用空调机与双工况复合制冷系统等几种冬季利用自然冷源的机房空调方案,并对各方案的优缺点和节能效果进行分析比较。对比分析的结果显示从节能效果和使用控制简便综合考虑双工况复合制冷系统是最佳选择。分析结果为程控机房的空调形式的选择提供参考依据。 【Abstract】 The building model of a typical telecommunication equipment room has been developed,with which the air conditioning dynamic load also have been analyzed by using DeST.The special air-conditioning requirements that the telecommunication equipment room should be refrigerated in winter and the load characteristics of the telecommunication equipment room have been analyzed,and several air conditioning systems which could use natural cold source in winter have been introduced,such as computer room air conditioning system which using fresh air directly,tower cooling,computer room air conditioning with REFNAC cycle and double conditions compound refrigeration system,also their strengths and weaknesses,and energy conservation effects have been compared.The results shows that considering both the energy conservation and the simple control structure,double conditions compound refrigeration system is the best choice for the telecommunication equipment room air conditioning system.It provides refe... 【关键词】 程控机房; 自然冷源; 节能; 冷却除湿; 等湿冷却 【Key words】 telecommunication equipment room; natural cold source; energy conservation; cooling dehumidification; constant humidity cooling
