Book Description
Academic Paper from the year 2017 in the subject Engineering - Power Engineering, Eastern Mediterranean University, language: English, abstract: The increase of occupant comfort demands are leading to rising requirement for air conditioning, but deteriorating global energy and environment crisis are starving for energy saving and environmental protection. The need to come up with the new energy saving as well as environmental friendly air conditioning systems has been more urgent than ever before. In hot and humid areas, the liquid desiccant air-conditioning systems based on evaporative cooling was proposed as a promising invention. This system overcomes the difficulty of evaporative cooler increased humidity with cooling, which makes it unsuitable for hot and humid climates, by dehumidifying the air first and then cooling it inside an evaporative cooler with water. The heating effect of dehumidification process is compensated by cooling water circulation. The use of dehumidifier in conjunction with an evaporative cooler increases the efficiency of the system. Some of the advantages of using this system are: it can remove the air latent load, environmental friendly, removes the pollutants from the process air and reduces the amount of the electrical energy consumed. The primary objective of this project is to design a solar based liquid desiccant evaporative system to purify and supply cool air. Liquid desiccant dehumidification has been proven to be an effective method to extract the moisture of air with relatively less energy consumption, especially compared with conventional vapor compression system. Inside the dehumidifier we used calcium chloride solution which after some period of time gets diluted with water and loses its moisture absorbing capacity and therefore, needs to be heated in the solar collector to ensure that the liquid desiccant does not lose its absorption capacity. In this project, several different aspects in solar assisted liquid desiccant based evaporative cooler have been considered. Some of these aspects include the availability of the materials, manufacturability of the product, sustainability of the product, health and safety regulations and the environmental effects of the product.

Book Description
The support for polygeneration lies in the possibility of integrating different technologies into a single energy system, to maximize the utilization of both fossil and renewable fuels. A system that delivers multiple forms of energy to users, maximizing the overall efficiency makes polygeneration an emerging and viable option for energy consuming industries. Polygeneration Systems: Design, Processes and Technologies provides simple and advanced calculation techniques to evaluate energy, environmental and economic performance of polygeneration systems under analysis. With specific design guidelines for each type of polygeneration system and experimental performance data, referred both to single components and overall systems, this title covers all aspects of polygeneration from design to operation, optimization and practical implementation. Giving different aspects of both fossil and non-fossil fuel based polygeneration and the wider area of polygeneration processes, this book helps readers learn general principles to specific system design and development through analysis of case studies, examples, simulation characteristics and thermodynamic and economic data. Detailed economic data for technology to assist developing feasibility studies regarding the possible application of polygeneration technologies Offers a comprehensive list of all current numerical and experimental results of polygeneration available Includes simulation models, cost figures, demonstration projects and test standards for designers and researchers to validate their own models and/or to test the reliability of their results

Book Description
Our energy system faces a fundamental transformation and renewable energies will play a dominant role in the future energy supply. One of the promising solutions is the use of solar thermal energy in buildings, for cooling, heating and domestic hot water preparation. Solar thermal systems for providing heat and cold to industrial processes show a high potential, too. In the last decade, the application of solar driven cooling systems achieved a significant progress. Steps forward have been taken in the design of system concepts to specific needs and in more reliable and efficient operation of the installed plants. New systems are available on the market and cover a broad range of cooling capacities and driving temperatures. This handbook provides an overview on the various solutions to convert solar heat into useful cooling, reports about experiences made with realized installations and gives support in the design process. Its use will strongly contribute to achieve high quality solar cooling systems which provide significant energy savings and fulfil the user’s requirements in a safe and reliable way.
