Book Description :

This book provides a manual for the technical and structural design of systems for supplying decentralised energy in residential buildings. It presents the micro-combined cooling, heating & power systems Stirling engines & renewable energy sources (mCCHP-SE-RES) systems in an accessible manner both for the public at large, and for professionals who conceive, design or commercialise such systems or their components. The high performance levels of these systems are demonstrated within the final chapter by the results of an experiment in which a house is equipped with a mCCHP-SE-RES system. The reader is also familiarized with the conceptual, technical and legal aspects of modern domestic energy systems; the components that constitute these systems; and advanced algorithms for achieving the structural and technical design of such systems. In residential buildings, satisfying demands of durable development has gradually evolved from necessity to obligation and institutionalisation. Consequently a major paradigm change has appeared in the supply of energy to residential buildings, from the centralised production of energy using fossil fuels to the decentralised production of energy using local renewable sources. Furthermore, on the energy system market, energy micro systems which use renewable energy sources are increasingly commercialised. From among these, the mCCHP-SE-RES systems are particularly striking because they offer a high performance and they enhance the relationship between humans and the environment. This book is intended for postgraduate students of electrical engineering, applied mathematicians, and researchers of modelling and control of complex systems or power system technologies.

Book Description :

Distributed energy systems produce energy on-site considerably reducing energy loss that would occur when energy is supplied from centralized systems. One of the distributed energy technologies is a combined cooling, heating, and power (CCHP) system. In a CCHP system, electricity is generated near end-users and the recovered heat from a power generation unit is utilized for cooling and heating in a building. Therefore, CCHP systems can increase primary energy utilization efficiency and energy reliability while reducing adverse environmental impacts. CCHP systems can be applicable from a building to community level. However, the feasibility of CCHP systems can largely vary with building type and location as well as other integrated sub-systems such as hybrid chiller and solar photovoltaic (PV) systems. This dissertation focuses on feasibility assessments of CCHP systems integrated with hybrid chiller and PV systems. Specifically, the work in this dissertation consists of investigations of energy, environmental, and economic performances of CCHP systems applied to various commercial building types in different climatic regions in the U.S.The first investigation evaluates the energy and environmental performances of CCHP systems operating with two distinct cooling systems (i.e., absorption chiller vs. hybrid chiller) based on primary energy consumption and carbon dioxide emission. This study focuses on a hospital and an office building in San Francisco, CA and Long Island, NY. The results show that CCHP hybrid chiller systems can reduce a significant amount of primary energy consumption than traditional CCHP systems that utilize only an absorption chiller, especially when the systems are applied to a hospital building. The significant reduction of the primary energy consumption is mainly because a hybrid chiller system can minimize undesirable boiler operations for absorption cooling. The reduced primary energy consumption can also lead to a decrease in carbon dioxide emissions although regionally-varying emission factors of the grid electricity notably influence the environmental performance of CCHP hybrid chiller systems.The second investigation focuses on the economic feasibility of different-sized CCHP hybrid chiller systems for large office buildings considering realistic electricity tariff structures in different geographic regions including San Francisco, CA; Boston, MA; and Miami, FL. The results show that CCHP hybrid chiller systems can be economically justifiable for regions with relatively high electricity price and low natural gas price such as San Francisco and Boston. The cost savings are mainly attributed to electricity cost savings. Specifically, if a local electricity tariff estimates demand charges as high as energy charges (e.g., a tariff structure in San Francisco), demand charges can contribute to about 40% of the electricity cost savings; thus, using simplified tariff structures that neglect demand charges can result in a noticeable discrepancy in economic analyses of CCHP systems or other analogous distributed energy systems. However, for regions with relatively high natural gas price and low electricity price (e.g., Miami), the operation cost of CCHP hybrid chiller systems is higher up to $0.4 million per year compared to that of a conventional separate heat and power (SHP) system.The third investigation integrates solar PV panels with CCHP hybrid chiller (CCHP+PV) systems as applied to a large office building in San Francisco, CA and examines the impacts of variabilities in energy demands and solar irradiance on the energy and economic performances of CCHP+PV systems. According to the results obtained in this study, the associated uncertainties marginally influence the energy performance of CCHP+PV systems whereas they can increase the operation cost by up to $75,000 per year. Such a great increase in the operation cost is mainly attributed to demand charges that tend to increase as the uncertainties are considered. This result implies that a deterministic model of a CCHP+PV system may significantly underestimate its operation costs and overestimate economic savings, thereby leading to overly optimistic economic viability.

Book Description :

Combined Cooling, Heating and Power (CCHP) presents an opportunity in commercial buildings to reduce electrical loads while increasing efficiency and emissions. In particular, High Temperature Fuel Cells (HTFCs) coupled with Absorption Chillers represent an opportunity to provide electricity, heating, and cooling to buildings at very high efficiencies. Because this combination has been demonstrated on only a few occasions, a need is evident for detailed system modeling and optimization to assure that the technology can meet its full potential and serve a wide variety of applications. In this thesis, the installation of a HTFC-Absorption Chiller system is analyzed and modeled in order to determine a favorable strategy for installation into an existing but generic commercial office building. Building loads were monitored and analyzed to establish the building electrical and HVAC demand. For the purposes of this system analysis, the HTFC is assumed to operate at steady state at all times. A steady state absorption chiller model was created in Aspen Plus® in order to analyze different operating points, given varied fuel cell exhaust conditions. Next, a dynamic absorption chiller model was created in Matlab Simulink®. This thermodynamic model incorporated mixing volumes, thermal mass, and transport delay in order to capture transient effects in the absorption chiller. The Aspen Plus® and Simulink® absorption chiller models were verified against manufacturer provided steady state data. Since the exhaust leaving the fuel cell during normal operating conditions was too high, analyses were performed with the steady state model to determine the best methods of reducing the temperature of the fuel cell exhaust. In parallel, simulations were run with the transient model to determine the ability of the absorption chiller to follow dynamic cooling loads throughout the day. Finally, representative load days were simulated while imposing operational constraints on the dynamic absorption chiller model. The use of a thermal energy storage (TES) tank was also analyzed. The most simple temperature reduction method, which alters the fuel cell steam-to-carbon ratio, is favored, combined with methods of diverting unnecessary exhaust from the chiller and sending it to a heat recovery unit. A heating-only mode, with the chiller configured for heat recovery, is the most effective method for energy utilization during the winter, when the cooling demand is marginal.

Book Description :

The goal of this study is to assess the potential of the Stirling engine in alternative energy applications including combined cooling, heating, and power (CCHP) and novel waste heat recovery (WHR) technologies. A first and second law model is developed to quantify Stirling engine performance and realize the crucial parameters in Stirling engine design. In addition, analysis of systems employing the Stirling engine as a prime mover can help justify particular design interests for the engine regarding certain applications. A model of a CCHP system is developed with a Stirling engine prime mover. Sensitivity analysis is performed on the CCHP system to gain a deeper understanding of how each component affects the overall performance of the CCHP system. The main objective of these analyses is to provide information on the feasibility of Stirling CCHP on the basis of primary energy consumption and cost. Finally, the potential of the Stirling engine as a waste heat recovery device is investigated. A thermodynamic model is developed to provide estimates of Stirling engine performance based on an available waste heat stream from any specific heat source, while suggesting practical design constraints on the engine based on bounds from the second law. These results are provided to strengthen the feasibility of the Stirling engine as a bottoming prime mover rather than the central power plant.

Book Description :

Combined cooling, heating and power (CCHP) systems are known as trigeneration systems, designed to provide electricity, cooling and heating simultaneously. The CCHP system has become a hot topic for its high system efficiency, high economic efficiency and less greenhouse gas (GHG) emissions in recent years. The efficiency of the CCHP system depends on the appropriate system configuration, operation strategy and facility size. Due to the inherent and inevitable energy waste of the traditional operation strategies, i.e., following the electric load (FEL) and following the thermal load (FTL), more efficient operation strategy should be designed. To achieve the highest system efficiency, facilities in the system should be sized to match with the corresponding operation strategy. In order to reduce the energy waste in traditional operation strategies and improve the system efficiency, two operation strategy design methods and sizing problems are studied (In Chapter 2 and Chapter 3). Most of the improved operation strategies in the literature are based on the ''balance'' plane, which implies the match of the electric demands and thermal demands. However, in more than 95% energy demand patterns, the demands cannot match with each other at this exact ''balance'' plane. To continuously use the ''balance'' concept, in Chapter 2, the system configuration is modified from the one with single absorption chiller to be the one with hybrid chillers and expand the ''balance'' plane to be a ''balance'' space by tuning the electric cooling to cool load ratio. With this new ''balance'' space, an operation strategy is designed and the power generation unit (PGU) capacity is optimized according to the proposed operation strategy to reduce the energy waste and improve the system efficiency. A case study is conducted to verify the feasibility and effectiveness of the proposed operation strategy. In Chapter 3, a more mathematical approach to schedule the energy input and power flow is proposed. By using the concept of energy hub, the CCHP system is modelled in a matrix form. As a result, the whole CCHP system is an input-output model. Setting the objective function to be a weighted summation of primary energy savings (PESs), hourly total cost savings (HTCs) and carbon dioxide emissions reduction (CDER), the optimization problem, constrained by equality and inequality constraints, is solved by the sequential quadratic programming (SQP). The PGU capacity is also sized under the proposed optimal operation strategy. In the case study, compared to FEL and FTL, the proposed optimal operation strategy saves more primary energy and annual total cost, and can be more environmental friendly. Finally, the conclusions of this thesis is summarized and some future work is discussed.

Book Description :

Many of the economic road blocks which have previously served to discourage the implementation of alternative power generation technologies can now be readily overcome through effective energy resource optimization. It is now a fact that solid financial returns can be achieved from combined heating, cooling and power generation projects by integrating energy and cost efficiency goals, and seeking a match between power production and heating/cooling requirements. This book is intended to serve as a road map to those seeking to realize optimum economic returns on such projects. The first section provides an introduction to basic heat and power thermodynamics, with an overview of heat and power generation technologies and equipment. The second section explores the infrastructure in which the project must be implemented, including environmental considerations, as well as utility rate structures. The third section provides detailed coverage of a broad range of technology types, and discusses how opportunities for their application can be identified and successfully exploited. The final section takes you through each step of project development, implementation and operation. Numerous examples are provided of actual field applications, with supporting documentation of system layouts and performance. The text is supplemented with more than one thousand graphics, including photos, cutaway drawings, layout schematics, performance curves, and data tables.
