The invention relates to a ventilation system for an air resistance reduction system of an ultra-large container ship, which comprises an exhaust fan set, a ventilation system, a control system and a control system, and is characterized in that the exhaust fan set is used for quickly discharging heat generated by an air compressor in an air compressor cabin; the air supply fan unit is used for providing the processing air amount required by the air compressor, providing low-temperature air for the air compressor cabin and maintaining the positive pressure of the air compressor cabin; the natural ventilation opening is used for maintaining the positive pressure of the air compressor cabin and discharging excess air in a natural ventilation mode; and the seawater cooling coil pipe system comprises a set of seawater pumps and a set of seawater cooling coil pipes, and the seawater cooling coil pipes are installed in the air supply air pipe system and used for reducing the air supply temperature. The ventilation system can effectively provide an external environment for normal work for the air compressor in all seasons, the seawater cooling coil pipe is adopted for reducing the air supply temperature, air supply and seawater are subjected to heat exchange firstly to reduce the air supply temperature, and therefore the air supply volume can be reduced, and arrangement of a fan and all indoor equipment is facilitated. Therefore, the energy-saving effect is better achieved.
本发明涉及一种用于超大型集装箱船空气减阻系统的通风系统,包括:排风风机组,用于将空压机舱室内空压机产生的热量快速排出;送风风机机组,提供空压机所需要的处理空气量,并为空压机舱室提供低温空气和维持空压机舱室正压;自然通风口,用于维持空压机舱正压,通过自然通风方式排出多余空气;海水冷却盘管系统,包括一组海水泵,一套海水冷却盘管,海水冷却盘管安装在送风风管系统内,用于降低送风温度。本发明提供的通风系统可以在各季节有效地为空压机提供正常工作的外部环境,并且采用了海水冷却盘管降低送风温度,先将送风与海水进行热交换降低送风温度,从而可以减小送风风量,方便风机及室内各设备布置。从而更好地达到节能效果。
