摘　　要：海洋石油平台上存在一部分散热量很大的电气房间,在冬季工况下仍需要对这些房间进行降温处理。为了解决寒冷地区大散热量房间冬季制冷问题,提出3种设计方案:压缩冷凝机组方案、乙二醇-制冷剂双系统方案、全新风变风量系统方案,并对各方案进行简要分析。研究结果表明,在寒冷地区冬季工况下,对大散热量电气房间采用全新风变风量系统比较合适。There are some electrical rooms with large heat dissipation on the offshore oil platform,which still need to be cooled under winter working condition.In order to solve the refrigeration problem of large heat dissipation rooms in cold regions in winter,three design schemes are put forward,namely,compressor condensing unit scheme,and ethylene glycol-refrigerant dual system scheme and full fresh air with variable volume system scheme,and each scheme is analyzed.The study results show that it is more appropriate to adopt the full fresh air with variable volume system for electrical room with large heat dissipation under winter working condition in cold areas.
