Improving Internal Combustion Engine Performance by Using Reduced Power Air Conditioning SystemBy Carlos Armenta-Déu
Abstract: The paper studies and analyzes the effects of adsorption air conditioning system instead of the classical compression unit on the vehicle internal combustion engine (ICE) performance. The adsorption system uses the residual heat from the ICE cooling circuit to create the necessary thermodynamic conditions to reduce the temperature in the vehicle cockpit. The proposed system has the advantage of no mobile parts for operating since it works on pressure difference …

Self-powered Portable Unit for Drinking Water ProductionBy Carlos Armenta-Déu
Abstract: The paper describes a new system to supply drinking water for human beverage requirements in natural disasters like earthquakes, volcano eruptions, flooding, hurricanes or typhoons. The system use solar energy to supply power to the drinking water production unit that operates using evaporation to obtain drinking water from dirty or polluted waters. The unit operates at low temperature thanks to the created vacuum, which reduces the evaporation point of water …

Analysis of Geological Structure for the Application of Geotechnical Engineering to Optimize Thermal Extraction in Geothermal WellsBy Carlos Armenta-Déu
Abstract: The characterization of the geological terrain for geothermal applications from the heat transfer point of view has been made. Horizontal, vertical and inclined geological layers have been analyzed. Uniform and homogeneous terrain are better candidates for low or high enthalpy geothermal applications while heterogeneous soil have a poorer performance from the thermal transfer point of view. The characterization process of soil structure and properties allows to take the appropriate decision …

GRID Energy Balance Using V2G Network SystemBy Laura Demas, Carlos Armenta-Déu
Abstract: In this work, a simulation process has been developed to evaluate the feasibility of compensating for the excess or shortage of energy in power generation. The simulation is based on the exchange of charge between the electrical network and a network of batteries that equip electric vehicles. The simulation process has taken as a reference study the evolution of energy generation and energy demand for a specific case in a …

HYBRID PV-TEG SYSTEM TO IMPROVE PERFORMANCEBy Carlos Armenta-Déu
Abstract: The use of Peltier cells as a system to use residual hot generated by photovoltaic panels while working is seen as a solution to the loss of performance in them because of the hot previously mentioned. At the same time it favors the production of electric energy because of the Seebeck effect. To determine the viability of a hybrid system photovoltaic panel and Peltier cell assembly it is essential to …

Layout Optimization of PV Arrays on Building Rooftop: Influence of Geographical Location and Weather ConditionsBy Carlos Armenta-Déu, F.J. de Segura-Muñoz
Abstract: The paper describes a methodology to determine whether or not a tilted PV array works better than a horizontal one on top of a building roof. Vertical and horizontal positioning of the PV panels for tilted PV array has been considered. The method is based on the maximum number of PV panels that can be installed on specific building rooftop surface and calculates the energy generated by the PV array,comparing …

MODELING COGENERATION SYSTEM IN SHALLOW GEOTHERMAL INSTALLATIONSBy Carlos Armenta-Déu
Abstract: ABSTRACTThis paper presents a theoretical modeling of a cogeneration system using multiple heat exchangers and thermoelectric generator. The modeled system, designed for shallow geothermal energy, is a closed piping unit containing water as heat transfer fluid that circulates through a closed loop releasing thermal energy at the surface for heating and sanitary hot water. In addition, a Peltier cells array is attached to the piping system to generate electricity, thus …
