现有船舶 meaning in Chinese
existing ship
Examples
- Aiming at the status of large energy consumption in ship air conditioning systems , considers that energy saving and efficiency improving mainly rely on operation maintenance and management for those ships in service , while the new techniques such as variable frequency of compressors and fans and electric expand valves to control refrigerating output should be introduced to reduce energy consumption for new built or refitted ships
摘要针对船舶空调系统能耗较大的现状，认为现有船舶应立足于在运行过程中加强对系统的维护管理，以实现节能增效；新造船舶或改装的船舶，应采用压缩机、风机变频技术以及利用电子膨胀阀调节制冷量，以实现更大程度的节能。 - Abstract : conventional ship propulsion methods meet some limitations in ship development towards high - speed , large - scale and high - power . a new ship propulsion method , integrated hydraulic propulsion ( ihp ) , was put forward to solve the problem . then further research work was done on the principle of ihp method . working condition - matching characteristic was discussed through the working condition matching characteristic chart . after that , the advantages and disadvantages of ihp method were given . and the pump and motor , important parts of ihp , was designed through physical analytical method . ihp method can be used extensively in some special kinds of ship for its own characteristics . to a certain extent , the limitation problem of ship propulsion method can be solved . ihp method diversifies the existing ship propulsion methods
