At present, variable air volume ( vav ) air - conditioning system is the main steam of the whole air conditioning system in china and abroad because of its large energy conservatioa however, since vav system is multivariable, strongly coupled, nonlinear and time variant, its design, performance and management are more difficult than constant air volume ( cav ) system, and stable control of the entire vav system is focused in particular in china study on the stability, the key condition of the vav operation, the paper divide the vav system into ahu part and terminal part based on the coordination control strategy
目前，變風量（ variableairvolume ， vav ）空調系統以其巨大的節能潛力逐漸成為國內外空調系統的主流。但是，變風量（ vav ）空調系統具有多變量、強耦合、非線性、時變的特點，因此它的設計、運行和管理都比定風量（ constantairvolume ， cav ）系統難度大。這也是限制vav系統更廣泛應用的一個重要原因。 -
Main propulsion equipments have been gradually improved. in addition, some additional systems are provided, such as the power station, deck machinery, refrigeration and air condition plant, freshwater generators, drinking water system, steam generating system, ballast and bilge system, and fire fighting system. the management of ship ' s power plant is also known as the engineering management, which is supervised and controlled by the engine department under the direction of the company ' s engine technology management department of the headquarters. owing to the complexity of power plant, the changeability of navigational conditions, and the seriousness of accident ' s consequences, it is essential to explore how to manage the power plant economically and reduce the occurrence of troubles so as to raise the shipping efficiency
隨著科學技術的發展，不僅推進設備逐步得到完善，而且還增設了諸如船舶電站、起貨機械、冷藏和空調裝置、制淡水裝置以及飲水、蒸汽、壓縮空氣、壓載、艙底、消防等系統。船舶動力裝置的管理即輪機的管理，是在船公司機務部門指導下由船上輪機部具體負責實施。因為船舶動力裝置的復雜性、船舶航行條件的多變性、發生事故後果的嚴重性，所以探討如何對輪機進行經濟性管理，減少故障，從而提高船舶的營運效率非常重要。 -
