Derived from this productive, energy and material consumption of gas and oil, the conditions have been generated for the configuration of an environmental crisis. In such a way that, there is an urgent need to carry out research that explores the various alternative sources of energy that today appear as an alternative to reduce the negative impact of industrial, agro-industrial and urban activities on the environment. This paper reflects on the problems that exist in Mexico around the development and marginal adoption of renewable energies as a productive source. While 91.2% of energy in Mexico is produced by burning fossil fuels, it can be established that the energy structure in Mexico is unsustainable. For this reason, a change in energy thinking based on efficiency and sustainability is required, considering both as axes for the use of renewable energies. The goals of the article are: 1) to present a context study, analyzing the production of electrical energy with fossil sources in Mexico, alluding to the difficulty of the transition towards the use of renewable energies. Second, the production of renewable energies in the country is analyzed to find out if investment in them is sustainable.","PeriodicalId":329432,"journal":{"name":"Revista de Energías Renovables","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121255149","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}

To carry out this work, an reciprocating internal combustion engine will be used, which is ready on a fully instrumented engine test bench. Firstly, the biodiesel production process is described, where soybean oil and canola oil have been used. Subsequently, the experimental section that has been used for the present investigation is described. The experimental tests are carried out: (i) modifying the degree of opening of the accelerator and (ii) using a constant load of the dynamometer. On the other hand, in the results section shows the performance of the two biofuels generated against diesel commercial. Also, in this section shows the percentage differences of: (i) engine power; (ii) mass fuel, (iii) thermal efficiency engine and, (iv) exhaust temperaturas. The tests have been carried out under different engine speed conditions of the reciprocating internal combustion engine. Where, the main average differences that have been registered in the engine test bench were: for engine power, 32 and 33%; for the mass fuel consumption of -4.5 and 5%, when using soybean biodiesel and canola biodiesel, respectively. These differences are due to the energy capacity of each biofuel and, the instantaneous evolution of combustion process inside the reciprocating internal combustion engine.","PeriodicalId":329432,"journal":{"name":"Revista de Energías Renovables","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133617462","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 is desired to measure current, voltage, and\u0000temperature under different operating conditions of a photovoltaic installation, in order to obtain the necessary information to later use it to determine its energy efficiency. In this work, current, voltage and temperature data are transmitted over a CAN network based on devices from the Microchip® family of microcontrollers. The network design is made up of slave nodes in charge of carrying out data acquisition and leading them to a CAN Central master node. This master node receives them, oversees timing tasks and connects via serial port to a personal computer. The programming environment used is MikroC® for dsPIC®. The process of sending the data can be observed through the MikroC® USART terminal, these are saved in a .txt file for later analysis with a scientific software. Experimental tests carried out with a group of commercial panels are reported under two operating conditions: short circuit and open circuit. The graphs are shown, and to validate the information provided by the acquired data, the relationships between the monitored variables are verified considering the knowledge obtained from the literature.","PeriodicalId":329432,"journal":{"name":"Revista de Energías Renovables","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121587308","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}

This method is applied in order to obtain the cooling load as exact as possible and thus avoid oversizing in air conditioning equipment, and by using thermal insulation, achieve a decrease in energy consumption and thus contribute to the reduction of CO2 emissions, to energy saving and therefore to sustainable development. The cooling load is calculated by applying the proposed methodology to three cases: model A, B and C. The results for the three test models, object of this study, are compared.
