from后面的压缩机额定功率（comp. rated power ）应当怎 ...？ surface area of condenser shall have 20% heat transfer capacity margin from comp. rated power as shown on the data sheets. 冷凝器表面积应该比照数据表中的对应额定功率高出２０％的传热能力． comp. rated power = compare rated power 比照额定功率查看更多
关于氢气的排空系统？ 2# tf123 這段文章是在談論排空管線的惰性氣體（如氮氣）的沖吹,說明如下: for hydrogen, syngas and carbon monoxide service, a purge is not required for vent pipe diameters up to and including 80 mm (3 in), regardless of length, because the potential hazard posed by the formation and ignition of a flammable mixture inside the vent system is considered to be negligible. for larger diameters, vent pipes equal to or less than 5 m in length do not require a purge 針對這一段 對於氫氣、合成氣及一氧化碳的排放系統來說，排空管路的直徑在 3 in （含）以內，不管長度如何，是不需要做氮氣沖吹的，因為在這樣的管徑，其形成可燃性氣體混合物並被點燃的可能性是可以忽略的；對於較大的管徑，長度在５公尺內也是不需要做惰性氣體（氮氣）沖吹 查看更多
