摘　　要：为了解海上升压站围护结构的传热特点,从海上升压站平直舱壁和瓦楞板舱壁的传热比较、主体围护结构结露验算、主体围护结构隔热分析等三个方面进行了探讨。结果表明,相同室内外温差下瓦楞板舱壁的传热量比相同防火等级的平直舱壁的传热量大而热流密度较小、内表面最低温度更低而内表面最高温度较高;在满足房间的防火等级要求下,在渤海区域尽量不用H120级防火舱壁,如若使用应增加保温层;根据GB 50176-2016《民用建筑热工设计规范》,在东海、黄海和渤海区域使用A0级舱壁和A60级舱壁不会有结露风险,在我国渤海、东海、黄海,A0级甲板、A60级甲板、H120级甲板内表面均无结露风险;应尽量使用淡色舱壁和甲板以利于节能。In order to understand the heat transfer characteristics of the enclosure structure of offshore booster station, this paper discusses the heat transfer comparison between flat bulkhead and corrugated bulkhead of offshore booster station, dew condensation checking calculation of main enclosure structure and heat insulation analysis of main enclosure structure. The results show that under the same indoor and outdoor temperature difference, the heat transfer of corrugated bulkhead is greater than that of straight bulkhead with the same fire rating, the heat flux is smaller, the lowest temperature on the inner surface is lower, and the highest temperature on the inner surface is higher;Under the condition of meeting the fire rating requirements of the room, H120fire bulkhead shall not be used in Bohai area as far as possible. If it is used, thermal insulation layer shall be added;There is no risk of condensation when A0 and A60 bulkheads are used in the East China Sea, Yellow Sea and Bohai Sea;In the Bohai Sea, East China Sea and Yellow Sea, there is no risk of condensation on the inner surface of A0 deck, A60 deck and H120 deck;Light colored bulkheads and decks shall be used as far as possible to facilitate energy conservation.
