1. ENERGETIC ANALYSIS OF AN ABSORPTION CHILLER USING NH3/LiNO3 AS AN ALTERNATIVE WORKING FLUID
Abstract This paper presents a thermodynamic model developed for a prototype absorption chiller using NH3/LiNO3 with 10 kW of nominal capacity. The study was undertaken using thermodynamic modeling based on the mass and energy balance, takes the overall heat transfer coefficients into consideration and uses the characteristic equation method. First, the resu

3. Determination of Moisture Levels, Protein and Water Absorption of Chicken Giblets
Abstract This study aimed at evaluating the levels of moisture, protein, water to protein ratio, and water absorption during chilling of chicken giblets (heart, liver, and gizzard) to set legal limits of water absorption during this process. The survey was conducted in the southern Brazil, the largest broiler-producing region of this country. Giblets (heart,

4. Thermodynamic analysis of gas turbine cycle using inlet air cooling methods
This work focuses on a comparative analysis among three compressor inlet air cooling techniques using a thermodynamic approach to simulate the gas turbine cycle. Firstly, a Base Case is tested to determine the gas turbine performance without any cooling method. The effect of site altitude on the power output gas turbine even without any cooling technique is

5. Analysis of Gas Turbine Performance with Inlet Air Cooling Techniques Applied to Brazilian Sites
Abstract: For geographic regions where significant power demand and highest electricity prices occur during the warm months, a gas turbine inlet air cooling technique is a useful option for increasing output. Inlet air cooling increases the power output by taking advantage of the gas turbine's feature of higher mass flow rate, due the compressor inlet temper

10. Simulation and otimizaÃÃo of plants of microcogeraÃÃo with the use of a module of configuration of tasks for the taking of decision in changeable demands / SimulaÃÃo e otimizaÃÃo de plantas de microcogeraÃÃo com a utilizaÃÃo de um mÃdulo de configuraÃÃo de tarefas para a tomada de decisÃo em demandas variÃveis
The restructuring of Brazilâs power sector has stimulated new studies about distributed power generation. As the governmental strategy proposes a larger share for natural gas in the energetic matrix, many research groups has been concentrating their studies in cogeneration, specially using natural gas. For example, the COGENCASA project studies a residentia
