Ventilation and air conditioning design analysis for battery rooms in data centers
摘要：
分析了数据中心蓄电池运行过程中的析氢及散热现象。通过计算蓄电池氢气产生速率，与密闭空间的氢气爆炸极限对比，提出了平时通风设计换气次数应为0.5～1.0 h-1。通过单体蓄电池充放电反应过程中散热量的对比，提出了夏季按均充散热量进行冷负荷计算，冬季按浮充散热量进行热负荷计算。结合数据中心蓄电池应用场景，给出了蓄电池室通风空调设计的建议。
Abstract：
Analyses the phenomena of hydrogen evolution and heat dissipation during the storage battery operation in data centers. By calculating the hydrogen generation rate of the storage battery and comparing it with the hydrogen explosion limit of the confined space, proposes the idea of making usual design ventilation rate 0.5 to 1.0 times per hour. Based on the comparison of heat dissipation rates during the charging and discharging reaction process of the single storage battery, proposes to calculate the cooling load according to the heat dissipation of equalizing charge in summer and the heating load according to the heat dissipation of floating charge in winter. Combined with the application scenarios of data center storage batteries, gives some suggestions of HVAC design for storage battery rooms.
