| As a representative of high-tech ships and an important medium of Marine tourism development,cruise ships will play an important role in managing and developing the ocean in the future.Comfort is an important indicator of cruise ship.Creating a good air flow environment in cabin will bring a good experience to passengers living in cruise ship.As a new type of air conditioning mode,air carrying energy radiant air conditioning system inherits the comfort of traditional radiation air conditioning,and effectively solves the problem that traditional low-temperature radiation plate is easy to condensation.In this paper,the accuracy of standard k-ε turbulence model and DO radiation model in numerical simulation is verified by referring to the experimental data of air carrying energy radiant air conditioning system in literature.Secondly,taking a typical cruise cabin as an example,this paper explores the application effect of the air carrying energy radiant air conditioning system in the cruise cabin,and makes a comparative study of the structural parameters and air supply parameters of the air carrying energy radiant air conditioning system from the perspectives of thermal comfort,air supply effectiveness,and pollutant removal effectiveness.The results show that the suitable height of the plenum chamber,the suitable opening ratio of the orifice plate and the air supply temperature are between 250～350mm,1.77%～4.91% and 10～12℃for the studied type of cruise ship accommodation.On this basis,a comparative study is made on four fresh air supply modes which are used in combination with the air carrying energy radiant air conditioning system.The four fresh air supply modes are tasking air supply,orifice-plate air supply,attached air supply and displacement air supply.By comprehensive comparison,tasking air supply is the best one among the four schemes.The research results of this paper can provide theoretical basis and technical reference for the design of air conditioning system of cruise accommodation. |
