"There was one little baby / who was born far away. / And another who was born / on the very next day. / And both of these babies, / as everyone knows, / had ten little fingers / and ten little toes." No matter which part of the world a baby comes from--born on the ice or in a tent--that baby has "ten little fingers / and ten little toes," the pleasing refrain of this rhyming tribute to the sweet universality of babies of all colors. Soft, rounded babies are captured in soft, rounded watercolors in this new Spanish-English bilingual board book edition

Описание: This book acts as a reference that provides readers with the broadest available single volume coverage of leading edge advances in the development and optimization of clean energy technologies. One of the objectives of this book is to conduct a primary energy analysis and economic evaluation of solar thermal and photovoltaic cooling systems used for air conditioning in office buildings that apply simulation systems. Due to the climatic conditions that influence the performance of these two systems, the comparison is made for three different climates corresponding to Palermo, Madrid and Stuttgart. For each climate, the same geometry and dimensions of a building are considered, but with different user profiles and construction. Consequently, different heating and cooling loads twelve cases in total are taken into consideration. Another purpose of this book is to highlight water consumption as a key design parameter in determining the most convenient cooling system and selecting the most appropriate location for Solar Parabolic Trough (SPT) plants. Considering the importance of water in guaranteeing environmental sustainability, a review of water consumption parameters is presented, and water consumption in the SPT plants that are in the planning stages for southern Spain are analyzed as examples. The selected region for the present study is exposed to high horizontal solar irradiance, undergoes large seasonal weather fluctuations (prolonged droughts) and is located far from the coast (determining the sites topography and soil availability). These characteristics demonstrate that water consumption is one of the decisive factors for the construction of new solar plants in similar locations worldwide, in addition to other considerations such as capital cost or plant efficiency.

Описание: This book develops a novel and simple, yet rigorous methodology that, by means of basic techniques and tools available to any engineer, enables the study of solar concentrator performance parameter scattering on the control of the solar field outlet temperature. Several simulations are performed considering a realistic solar field comprised of a large set of solar collectors with slight differences in performance. Sets of scattered parameter distributions are randomly assigned to the collectors in the solar field. Sensitivity analysis of solar field behavior is then performed in terms of the distribution of the performance parameters of the solar collectors, followed by a comparison between different configurations of the solar field according to the number of subfields. The latter is of great interest in order to evaluate the effect of a subfield number on the ability of the solar fields operator to control the temperature of the solar field when a flow control valve is not available in each loop. As a special feature, this book proposes a new model for characterizing the energetic behaviour of grid connected PV inverters. The model has been obtained from a detailed study of the main loss processes in small size PV inverters in the market. The main advantage of the used method is to obtain a model that comprises two antagonistic features, since both are simple, easy to compute and apply, and accurate. One of the main features of this model is how it handles the maximum power point tracking (MPPT) and its efficiency: Concerning both parts, the model uses the same approach and is achieved by two resistive elements which simulate the losses inherent to each parameter. This makes this model easy to implement, compact and refine. The model presented here also includes other parameters, such as the start threshold, standby consumption and islanding behavior. As an example, the model has been implemented in the PSPICE electronic simulator, and this approach has been used to teach grid-connected PV systems. The use of this model for the maintenance of working PV facilities is also shown.

Описание: Among other things, this book analyzes the energy losses in transformation systems composed of parallel transformers and proposes a method known as PLO that allows for the reduction of these losses. Distribution transformer system losses represent an important contribution to the quantity of GHG emitted to the atmosphere and have a high economic cost. This book benefits the reader by proposing and validating a novel method for the transformer utilities of three efficiency levels. This method can be implemented with any transformer, regardless of its characteristics. New low-loss transformers have lower losses but higher economic cost, and so their installation is cost-effective only if the total cost over the life cycle is lower. However, replacement of existing transformers is rarely profitable. This book proposes a method to reduce losses throughout the life cycle in new or existing installations. For implementation, the system does not require any additional device and allows energy savings of up to 41% to be obtained over the initial losses when it is used in parallel transformers; the study also proposes using an automated system instead of manual disconnection. The new energy measurement equipment in smart grid systems facilitates the installation and operation of this method. Due to its contribution to the current pool of knowledge for topics such as repowering and renewable distribution systems, this book is an ideal resource for those interested in renewable energy, electric power systems and their applications.

Описание: The main objective of this book is to evaluate alternative energy systems in buildings regardless of their location and climatic conditions. To do so, evaluations have been conducted in temperate and marine weather conditions in developed countries like Germany; in a semiarid climate in Spain; and in a humid subtropical climate in Brazil. Over the past few years, the use of passive cooling and heating technologies has become more common for reducing the energy consumption of buildings. However, these technologies are not often used for some building systems. Buildings intended for children or the elderly are often climatized to improve indoor thermal conditions. In this book, a cost reduction in climatization based on passive systems is proposed and studied. Building site optimization is performed to improve thermal behavior. To achieve this, computational fluid dynamics tools have been used. The integration of these passive systems allows the peak power demand to be reduced by up to 50% and the yearly energy consumption to be reduced by approximately 40%. These reductions are studied for conventional and renewable energy systems, showing that passive systems provide better thermal comfort and reduce initial investment and energy consumption, making low-cost buildings feasible.
