Available in PDF, EPUB and Kindle. Book excerpt: With the increase in electricity prices and environmental concerns, new technologies are being developed to extract energy from every available source and store the excess energy generated for later usage. One such solution is provided by Thermal Energy Storage Systems. Solar radiation in summer can be stored inter-seasonally to provide heating in winter, while the cold from winter air can be used to run air conditioning in summer. This thesis studies in detail the solar thermal energy storage system used for domestic water heating purposes in a typical detached home in St. John's, Newfoundland, Canada. It introduces the topic, discusses the background and development of the systems, and presents the basic concept of what a solar thermal energy storage system is and how it works. As well, it focuses on the availability of solar radiation, which is important for analyzing how effective the system can be, considering that the amount of solar radiation is not constant throughout the earth. In-depth information on how thermal energy storage system functions and operates, along with an extensive review of the literature, is also featured. Studies including experimental and simulation models are reviewed, which helps to compare earlier approaches to the present handling of the problem. Additionally, to establish the findings of the thesis, a simulation model of solar thermal energy storage for domestic water usage is created with the help of SAM software. Various parameters of MATLAB software are taken into consideration as well to establish the desired design of the system. These design parameters are extensively explained, together with a discussion on the assumptions and design technologies considered for creating the model for the MATLAB and BEopt simulations. Overall, this thesis demonstrates a method of designing a solar water heating system with thermal storage that can provide hot water for a small house. SAM and HOMER, which are design models that calculate the consumption of hot water and cost for a system, are extensively utilized in the study.

This book was released on 2021 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space heating is required in almost every dwelling across the country for different periods of time. The thermal energy needed to meet a heating demand can be supplied using different conventional and/or renewable technologies. Solar energy is one example of a renewable resource that can be used for supplying heating needs. It can be utilized either by using photovoltaic panels to generate electricity, that in turn can be used to operate heaters, or by using solar thermal panels. Solar thermal panels obtain higher operating efficiencies than photovoltaic panels, but solar energy for heating purposes suffers from a mismatch between supply and demand. This problem can be solved by employing large tanks that serve as seasonal thermal energy storage units. This work focuses on assessing the performance of solar thermal panels in supplying the space heating needs of a single-family dwelling in two different cities in the United States. These panels are coupled to a cylindrical tank buried in the ground for seasonal and daily energy storage, and a heat exchanger to transfer heat to the home. Storage tank size, collector area, and the working fluid mass flow rate are investigated to determine adequate values for these parameters to enhance the overall system performance. In addition, the simulation timestep for the program and the spatial grid sizes used in the CFD (computational fluid dynamics simulation) model of the storage unit have been examined to determine values of each to keep the simulation time reasonable without substantial loss in accuracy. These results are obtained by mathematically modeling the system components, the solar thermal panels, the heat exchanger, and the storage tank; then programming this mathematical model in MATLAB. Parts of the developed computer code were obtained from previous work and have been modified to suit the purpose of this project. Flat plate solar panels have been chosen for use as the solar collectors. An unmixed, crossflow heat exchanger is considered for transferring the thermal energy from the glycol-water mixture in the collectors to the air in the house. The storage unit CFD simulation is composed of the tank, insulation, and ground surrounding the tank and is based on the SIMPLE algorithm developed by Patankar.

This book was released on 1991-04-30 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to facilitate detailed solar system simulations and to make such simulations readily available to solar engineers in their daily practice of system dimensioning and performance calculations, user friendly software for personal computers has been developed as a system specific simulation program for a frequently installed group of water based solar system types. The program package has been developed as part of the OPSYS R&D-program of the Commission of the European Communities and has been named EURSOL. The set of system configurations considered includes different types of thermal solar systems for space heating and hot water production. The simulations are based on validated physical system models. The program offers complete freedom with regard to all parameters describing the systems and includes on-line help, economic evaluations and graphical output. This book describes the system considered in EURSOL, the mathematical algorithm, the physical model of each component used, the processing of solar radiation data and the economic evaluation criteria. Although the book is mainly a manual for the use of the simulation program, it is also a guide for the development of simplified simulation models for solar systems.
Download or read book Renewable Energy in District Heating and Cooling written by International Renewable Energy Agency (IRENA) and published by . This book was released on 2017-03-04 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: District heating and cooling (DHC) combined with renewable energy sources can help meet rising urban energy needs, improve efficiency, reduce emissions and improve local air quality. Although currently dominated by fossil fuels such as coal and gas, DHC systems can be upgraded, or new networks created, to use solid biofuel, solar and geothermal energy technologies. Depending on local conditions, renewable-based DHC brings a range of benefits, including increased energy security, improved health and reduced climate impact.To date, only a few countries have taken advantage of their renewable resource potential for DHC or created policies to promote further uptake. Sweden and Switzerland have started promoting renewable-based district heating,while Denmark - with ambitious decarbonisation policies -already uses high shares. Many cities and regions envisage a growing role for district in their energy plans; some are also looking increasingly at district cooling.As this REmap sector study from the International Renewable Energy Agency (IRENA) shows, renewables could feasibly supply more than one fifth of the energy needed for DHC worldwide. But to drive the transition, policy makers need to fully understand the costs, bene¿ts and actual potential for renewable-based DHC.

Download or read book Computer Modeling Of A Solar Thermal System For Space Heating written by Dhananjay D. Deshpande and published by . This book was released on 2016 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most applications of flat plate, low-temperature solar thermal panels are for water heating, such as producing domestic hot water or raising the temperature of swimming pools. This is reasonable given that the large masses of water present in these systems inherently provide built-in thermal energy storage so that a separate energy storage tank does not have to be purchased. For a space heating system, extra thermal energy storage generally has to be purchased and is a detriment to the economics of these systems. Despite the economic drawbacks of solar thermal space heating, this thesis focuses on the size of thermal systems required to heat an average size home in Minneapolis, MN and Dayton, OH. For these two locations and for a standard test case, this thesis studies the effect of solar panel size and orientation, heat exchanger size, and operation parameters including flow rates through the solar panels and heat exchanger. Liquid, flat plate collectors are one of the simplest methods for collecting solar energy. These panels are generally inexpensive and can have collection efficiencies above 50%. This makes solar thermal panels more efficient than solar photovoltaic panels, which generally have efficiencies less than 20%. Since the solar thermal panels chosen for study in this work heat a liquid with the sun{u2019}s energy and the fluid being heated in the building is air, a heat exchanger has to be included in the model. Lastly, because solar thermal systems are inherently unsteady, thermal energy storage must be included in the model. These components of a solar thermal space heating system are modeled by writing and adding routines to the Wright State developed simulation program called Solar_PVHFC. Solar_PVHFC is a simulation program which models solar photovoltaic panels coupled with fuel cells and hydrogen storage tanks. Because of this work, Solar_PVHFC is now capable of modeling a solar thermal system. The advantage of coupling this solar thermal work to Solar_PVHFC is that Solar_PVHFC does a very detailed calculation of the solar energy impinging upon a surface at any location, at any time, for any orientation. This is required to properly model solar thermal systems. The program modules that perform the simulation of the solar thermal system components are written in MATLAB, just like the Wright State developed program Solar_PVHFC.

Available in PDF, EPUB and Kindle. Book excerpt: During the last two decades many research and development activities related to energy have concentrated on efficient energy use and energy savings and conservation. In this regard, Thermal Energy Storage (TES) systems can play an important role, as they provide great potential for facilitating energy savings and reducing environmental impact. Thermal storage has received increasing interest in recent years in terms of its applications, and the enormous potential it offers both for more effective use of thermal equipment and for economic, large-scale energy substitutions. Indeed, TES appears to provide one of the most advantageous solutions for correcting the mismatch that often occurs between the supply and demand of energy. Despite this increase in attention, no book is currently available which comprehensively covers TES. Presenting contributions from prominent researchers and scientists, this book is primarily concerned with TES systems and their applications. It begins with a brief summary of general aspects of thermodynamics, fluid mechanics and heat transfer, and then goes on to discuss energy storage technologies, environmental aspects of TES, energy and exergy analyses, and practical applications. Furthermore, this book provides coverage of the theoretical, experimental and numerical techniques employed in the field of thermal storage. Numerous case studies and illustrative examples are included throughout. Some of the unique features of this book include: * State-of-the art descriptions of many facets of TES systems and applications * In-depth coverage of exergy analysis and thermodynamic optimization of TES systems * Extensive new material on TES technologies, including advances due to innovations in sensible- and latent-energy storage * Key chapters on environmental issues, sustainable development and energy savings * Extensive coverage of practical aspects of the design, evaluation, selection and implementation of TES systems * Wide coverage of TES-system modelling, ranging in level from elementary to advanced * Abundant design examples, case studies and references In short, this book forms a valuable reference resource for practicing engineers and researchers, and a research-oriented text book for advanced undergraduate and graduate students of various engineering disciplines. Instructors will find that its breadth and structure make it an ideal core text for TES and related courses.
