A mobile container shall be produced for the transport, storage and preservation under optimum conditions of cereals, vegetables or fruit. Lowering the temperature and humidity with the help of the sensors and the air conditioning unit make it possible to store in the optimal conditions in the long term the products we want to store. If we lower the temperature we will be able to keep the cereals in the long term, but the humidity of each type of cereal, vegetable or fruit should be kept under control. If the humidity is too high they will have to be dried with the help of the temperature increasing it. The temperature will be restored to optimal storage parameters.","PeriodicalId":129030,"journal":{"name":"2019 International Conference on Electromechanical and Energy Systems (SIELMEN)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124065999","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}

The method requires as restriction the statistically independence of the additive components. In the paper, ICA was used to reconstruct some statistically independent signals (power requests according to consumer load profiles) from a mixture of signals (power flows on branches). The ICA algorithm does not require knowledge of network parameters or configuration. The consumer load profiles obtained by the independent component method overlapped with a very good approximation over the real load graphs of consumers used in modeling.","PeriodicalId":129030,"journal":{"name":"2019 International Conference on Electromechanical and Energy Systems (SIELMEN)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124884760","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}

In the present paper is modeled the behavior of a building, divided into different thermal zones with intermittent occupancy. A separate pre-processing program based on the building structure, material’s characteristics, and geographic position is firstly executed. It is presented the mathematical model used in the optimization scheme for the windows, walls, floor, and ceiling and part of the numerical results for the heating systems, ventilation, and air conditioning for a personal building. As the main step for the input data is selected the functioning plan, scheduled based on the owner program, a residential building. The management is finally dedicated to optimize the building energetic consumption.
