Research On Technology Of HVAC Noise Design On Luxury Yacht

Super yacht is a high-end industrial product created by craftsmen.With the rapid development of the global economy,super yacht has gradually become one of the consumer goods that high-end consumers are competing for after luxury cars.The design of super yacht is different from that of ordinary ships.As a high-end industrial product,super yacht is designed from appearance design to internal use.Every detail has the customer's individualized requirements for her.Super yacht has higher comfort requirements than ordinary ships or even high-end ships.It is called a five-star hotel at sea to ensure the comfort requirements of customers 'high-end entertainment machines.HVAC is the key system to ensure the comfort of luxury super yacht.To ensure that the temperature,humidity and noise in the cabin are in the optimal state,create a very comfortable environment,and how to ensure the high-end comfort and low noise quality of luxury super yacht,this poses a higher challenge to the design of the HVAC system of luxury super yacht.Aiming at the 88m luxury super yacht ILLUSION built by CIMC yacht Co.Ltd.,this paper discusses the difference between HVAC noise standard of HVAC system and HVAC noise standard of conventional engineering ships,the research content of low noise of HVAC system of luxury super yacht,the matters needing attention in HVAC construction design of super yacht,and studies the main contribution sources of HVAC system to cabin noise from three aspects.The subsequent HVAC design of the luxury super yacht with high comfort can be used as a reference,and the feasibility of the design scheme is verified by the prior simulation calculation and experiment.Firstly,this paper discusses the similarities and differences between the existing HVAC noise regulations and standards in the world,and the differences between the HVAC noise standards of luxury Super Yachts and those of conventional engineering ships.According to the criterion,the noise characteristics of the target luxury ILLUSION yacht are evaluated and analyzed.The results basically meet the requirements of specifications,laws and regulations and classification societies,which proves that the luxury super yacht built in China has good comfort performance.Secondly,the causes of noise in HVAC system are analyzed in depth.According to the characteristics of HVAC noise contribution sources and transmission paths,classification research is carried out.Through physical model test,the maximum sound insulation of HVAC cabin is studied,and the optimization of duct noise transmission is studied through calculation and analysis.Based on the statistical energy software VA ONE,the optimal layout of airflow noise in the cabin environment HVAC system was studied.Finally,by considering the above analysis and research results,the HVAC system is rationally optimized in the process of ship construction,and a series of solutions are put forward from the aspects of design,layout and technology.The final test results show that the scheme is feasible and effective,and has practical engineering application value.
