The invention discloses an air circulation system and an air circulation method of FPSO, which are used in a living building of the FPSO. The air circulation system comprises an air collection system,an air return system, an air supply system, an exhaust system and a system control device, wherein the air collection system is used for pumping fresh air from the outside; the air return system is used for carrying out mixed circulation on air in a cabin; the air supply system is used for supplying air to all positions in the cabin; the exhaust system is used for exhausting the air in the cabinto the outside; and the system control device is electrically connected with the above systems. Air pipes of all the systems are the same; an air volume value is equal to a product of the unit time, an air speed value and an air pipe section area; the system control device can continuously detect and adjust the wind speed of each system; and a sum of a fresh air volume of the air collection systemand an air return volume of the air return system is equal to an air supply volume of the air supply system, and the sum of the air supply volume of the air supply system and the air return volume ofthe air return system is smaller than the air supply volume of the air supply system so that positive pressure is formed between the cabin and the outside, outside air difficultly enters the cabin, and safety of living areas is improved.

    本发明公开了一种FPSO的空气循环系统及空气循环方法,其用于FPSO的生活楼中,该空气循环系统包括:采风系统,用于从外界抽送新风;回风系统,用于对舱内空气进行混合循环;送风系统,用于向舱内各处送风;排风系统,用于将舱内空气排至外界;系统控制装置,电连接于上述各系统,上述各系统的风管相同,风量的值等于单位时间与风速的值和风管截面面积的乘积,系统控制装置能够持续检测并调节上述各系统的风速,使采风系统的新风量和回风系统的回风量之和等于送风系统的送风量,送风系统的送风量和回风系统的回风量之和小于送风系统的送风量,从而在舱内和舱外之间形成正压,外界的气体就很难进入舱内,提高了生活区域的安全性。
