Item Energy and exergy analysis of a adsorption chiller(2019-10-20) Soares, José Josimar; Gomes, Joseh Emmanuel de Sousa; Gurgel, José Maurício Alves de Matos; Melo, Francisco José AraújoThis paper shows the energy and exergy analysis of a two-bed adsorption chiller. The system was developed at LES/CEAR/UFPB, and constitutes of two adsorption reactors, a condenser and an evaporator, which function independently. Cycle times and secondary flow switching control scheduling is performed using a LabVIEW® interface that allows automatically secondary flow control through the cycle management system (SGC). The experimental tests were performed with the silica gel / water adsorptive pair. The specific cooling capacity (SCP) and coefficient of performance (COP) of the two-reactor chiller were 81.4 W kg-1 and 0.52 respectively, with an exergetic efficiency of 8.2% for the best working conditions, represented by the triplet 72/30/15 ℃ and a cycle time of 35 min. The results reached the levels of recent publications of literature describing models with the same characteristics. The maximum temperature required for the operation of this system is compatible with the use of low-temperature industrial thermal waste and flat type solar collectors, which may allow its production on a commercial scale.Item Sequência didática baseada na energia solar fotovoltaica como auxílio ao ensino de física no 3º ano do ensino médio(2019-12-20) Cruz, Alê de Souza; Anglada-Rivera, José; http://lattes.cnpq.br/5724564590431920; Anglada-Rivera, José; http://lattes.cnpq.br/5724564590431920; Borges, Denilson da Silva; http://lattes.cnpq.br/7149037835888302; Silva, Ronaldo Santos da; http://lattes.cnpq.br/4548331237405072; Ruiz, Yurimiler Leyet; http://lattes.cnpq.br/448559622795252; http://repositorio.ifam.edu.br/jspui/handle/4321/649Item Sequência didática baseada na energia solar fotovoltaica como auxílio ao ensino de física no 3º ano do ensino médio(2019-12-20) Cruz, Alê de Souza; Anglada-Rivera, José; http://lattes.cnpq.br/5724564590431920; Anglada-Rivera, José; http://lattes.cnpq.br/5724564590431920; Borges, Denilson da Silva; http://lattes.cnpq.br/7149037835888302; Silva, Ronaldo Santos Da; http://lattes.cnpq.br/4548331237405072; Ruiz, Yurimiler Leyet; http://lattes.cnpq.br/4485596227952529; Nunes, Wagner Antônio da Silva; http://lattes.cnpq.br/0253265789709463A current problem for the teacher working in science is the lack of motivation of students facing current teaching methods, where many schools, even in very traditional schools have been changing their approaches with practical classes, construction of laboratories both science as of robotics. These changes can be noticed with greater intensity in private schools (CASTRO, 2015). But what do we do to change the current panorama of our public schools? This is one of the initiatives of this work that comes to assist the teacher of the Third Year of High School in the experimental area, making use of new technologies such as photovoltaic solar energy to work subjects within the area of electricity. Taking into consideration the environmental area and the incentive to use renewable energy. With this kind of activity we can encourage the elementary school student to explore other ways of producing electricity by taking advantage of what is abundant in our region that is solar energy. Taking into account the previous knowledge of the student to have a more meaningful learning.Item Projeto de um sistema de refrigeração e climatização por adsorção que utiliza o par de trabalho carvão ativado e etanol(2021-04-08) Silva, Francisco Mikael Alves da; Soares, José Josimar; http://lattes.cnpq.br/8049341977402653; Soares, José Josimar; http://lattes.cnpq.br/8049341977402653; Costa, José Francisco de Caldas; http://lattes.cnpq.br/5703032306296974; Rodrigues Filho, João Nery; http://lattes.cnpq.br/3860803328978892This project seeks to carry out the design of an alternative cooling system, where all the components of a laboratory scale prototype of an adsorption cooling system using the activated carbon and ethanol working pair will be dimensioned. The proposed system uses the principle of a four-motor engine to replace the compressor used in conventional air conditioning equipment by steam compression. Therefore, its operation does not depend on electrical energy, as it uses solar energy and uses refrigerant with low environmental impact. In the search for better performance, a new reactor will be designed, by increasing the contact area and reducing the thermal inertia of the reactor. Thus, with the making of this system, it will be possible to obtain a result compatible with the state of the art of models with the same technical characteristics and operating conditions.
