Abstract In recent years, the dedicated outdoor air systems(DOAS) develops so fast that some scholars in the air conditioning industry devoted themselves to the related research, which is mainly to improve air quality in the cabin。 And,what’s more, this paper also focus on the dedicated outdoor air systems, mainly in its feature and its trend of development。

Besides, there are three advantages in this paper。 Firstly, this design tried to apply the dedicated outdoor air systems to ships and calculate it and analyze its performance。 Secondly, this paper calculated the load of cabin by the cold load coefficient method, which could accurately calculate the amount of air supply in cabin, meanwhile, to choose the most suitable equipment, this paper compared many products from various companies。 In addition,thishe design also carries out the wind pipe hydraulic calculation, through the calculation of the wind pipe friction loss and local loss to calculate the total pressure of the wind turbine, and then according to the parameters of the manufacturers of wind turbine selection。This paper designed some related measures in some aspects― pipe insulation, reducing system noise and pipeline corrosion painting。 All in all, air conditioning system design needs to comply with the development of science and technology, and this paper studied the dedicated outdoor air systems in cabin, which could help improve air quality。

The application of the dedicated outdoor air systems in the ship has a great effect on the safety performance of the warship。

Keywords: marine air conditioning system; dedicated outdoor air systems; indoor air quality; flesh air handling unit
