Firstly, the investigation direction was outlined to explore different catalyst combinations and study the relationship with ethanol conversion, C4 olefin selectivity and temperature. In addition to this, the temperature linkage with different catalysts was added to analyze the catalyst components that have the greatest effect at different temperatures and the catalyst components that have the least effect. In addition, the optimal catalyst combination and temperature were further selected to optimize the yield of C4 olefins under the same experimental conditions, and the solved multiple regression equations were used as the constraint variables to establish the particle swarm algorithm model, and finally, MATLAB software was used to program the optimal catalyst composition parameters and temperature data.","PeriodicalId":188294,"journal":{"name":"International Journal of New Developments in Engineering and Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128862547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has become an inevitable trend to look for refrigerants with low ODP (Ozone Depletion Potential) and GWP (Global Warming Potential) to replace the refrigerants that are harmful to the environment. In addition, we also need to consider the COP (Coefficient Of Performance) and safety of refrigerants. This paper is based on a single-stage vapor compression refrigeration system, The COP of different refrigerants are calculated and analyzed under five different working conditions. After calculation, the COP of R717 is the highest under five working conditions, and its GWP is 0, but its safety level is only B2L.Therefore, it is very difficult to take into account the various properties of refrigerants at the same time. all the","PeriodicalId":188294,"journal":{"name":"International Journal of New Developments in Engineering and Society","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116142513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How to design products in a targeted manner to meet the needs of consumers has become a key issue for enterprises. In order to improve the efficiency of product design, this article has carried out a research on the design of a new refrigerator product that a company plans to launch based on virtual reality technology. First, based on the conventional new product launch process, virtual reality technology is incorporated in the two links of market research and prototype testing. The virtual research client was tested after research and development. The average score was 9.32 for stability, 9 for ease of operation, and 8.86 for experience comfort. After optimizing the comfort level, a virtual survey was randomly launched on the home appliance shopping website. Analyze the general situation of 1258 users, the factors that affect refrigerator buying behavior, and the acceptable price of refrigerators. Among the 1,258 users who participated in the virtual survey, the male to female ratio was 0.9:1, and the age was mainly between 25 and 35. The number of people with high school education was the largest, accounting for 39.6%, 46% of users believe that price is the primary factor they consider when buying a refrigerator, and the generally accepted range is around 3,000 yuan. After obtaining sufficient demand and market information, develop new products, build a virtual design database, perform scene modeling, texture mapping, and achieve interactive effects. Of the 739 users who participated in the virtual experience, only 526 of them thought it was more comfortable during the experience. Therefore, it is necessary to improve the comfort during the experience. Only 59 people are very satisfied with the appearance of the refrigerator, and the appearance of the new refrigerator should be adjusted in time to meet market demand. The user's purchase intention ratio for the three refrigerators A, B and C is 1:3:1.6, and production can be arranged according to this ratio. The total cost of virtual design is 154,800 yuan less than traditional design, and the total time is 23 days less. This shows that product modeling design based on virtual reality technology can save costs and improve efficiency, and it is worth promoting.","PeriodicalId":188294,"journal":{"name":"International Journal of New Developments in Engineering and Society","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123778052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After reviewing existing literature, it has been found that the global value chain reconstruction of China's manufacturing industry mainly involves three paradigms: producer driven, buyer driven, and co driven by producers and buyers; In terms of internal mechanisms, the driving factors that affect the reconstruction of China's manufacturing global value chain mainly include new value allocation, the evolution of international division of labor within products, the re decomposition and integration of the value chain, scientific and technological progress, and major risk events. The main obstacles include the loss of cost advantages of factors, conflicts with digital trade rules, low global value chain competitiveness, long-term trapped in the low-end of GVC, and the lack of core technological capabilities Six factors, including internal disharmony in the value chain cycle system; On this basis, this article further sorts out the paths for China's manufacturing industry to break through the \"low-end lock-in\" trap of the global value chain and achieve global value chain reconstruction, including: coordination at the macro, meso, and micro levels, interaction at the three levels of the industrial chain, supply chain, and value chain, as well as mutual penetration of GVC, RVC, and NVC.","PeriodicalId":188294,"journal":{"name":"International Journal of New Developments in Engineering and Society","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133599487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
