2. Characterization of new selective coatings, made of granite and chrome, for solar collectors
ABSTRACT The depletion of fossil fuel reserves and climate change caused by atmospheric pollution has led the human being to seek alternatives that are less damaging to the environment. The concern and the awareness of the population open space for the study of renewable energies to be deepened, among them the best use of solar energy. The use of alternative

3. APROVEITAMENTO DE FONTES ALTERNATIVAS PARA REDUÇÃO DO CONSUMO DE ENERGIA ELÉTRICA E REFLEXOS NOS SEUS CUSTOS / UTILIZATION OF ALTERNATIVE SOURCES FOR REDUCING POWER CONSUMPTION AND ITS CONSEQUENCES IN COSTS
Residential consumption accounts for around one third of total energy consumed in Brazil. The electric shower is the main component of this consumption, along with air conditioning. Hence, much research has been conducted in order to reduce the consumption of this sector and the use of alternative energy sources. Among these include mainly solar and geotherm

6. Análise do desempenho térmico de um sistema de aquecimento solar utilizando coletor com superfície absorvedora em chapas de PVC
Its presented a solar collector to be used in a system for heating bath water, whose main characteristic is its low cost. The collector consists of five plates of PVC with 10 mm thick, 200 mm in width and 1400mm in length, with an area equal to 1.4 square meters. The plates were connected in parallel to the ends of PVC tubes of 40 mm and 32

9. Avaliação de um sistema de refrigeração por adsorção para produção de gelo, operando diferentes tipos de ciclo com baixas temperaturas de geração. / Evaluation of a system of refrigeration for adsorção for ice production, operating different types of cycle with low temperatures of generation.
The goal of this project was to design and built a prototype of an adsorption refrigeration system for ice production with cycle operation flexibility. The prototype was to be powered by different energy sources. To reach this goal, the properties and characteristics of some adsorbents and adsorbates were compared and ammonia was chosen as adsorbate and carb
