Design of a Solar assisted Liquid Desiccant based evaporative Cooler by Zaeem Ahmer,Muhammad Hassan Saeed,Saad Elahi,Hassan Elghazali,Munther Mouzaneh Pdf

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.

Desiccant-Assisted Cooling by Carlos Eduardo Leme Nóbrega,Nisio Carvalho Lobo Brum Pdf

The increasing concern with indoor air quality has led to air-quality standards with increased ventilation rates. Although increasing the volume flow rate of outside air is advisable from the perspective of air-quality, it is detrimental to energy consumption, since the outside air has to be brought to the comfort condition before it is insufflated to the conditioned ambient. Moreover, the humidity load carried within outside air has challenging HVAC engineers to design cooling units which are able to satisfactorily handle both sensible and latent contributions to the thermal load. This constitutes a favorable scenario for the use of solid desiccants to assist the cooling units. In fact, desiccant wheels have been increasingly applied by HVAC designers, allowing distinct processes for the air cooling and dehumidification. In fact, the ability of solid desiccants in moisture removal is effective enough to allow the use of evaporative coolers, in opposition to the traditional vapor-compression cycle, resulting in an ecologically sound system which uses only water as the refrigerant. Desiccant Assisted Cooling: Fundamentals and Applications presents different approaches to the mathematical modeling and simulation of desiccant wheels, as well as applications in thermal comfort and humidity controlled environments. Experts in the field discuss topics from enthalpy, lumped models for heat and mass transfer, and desiccant assisted radiant cooling systems, among others. Aimed at air-conditioning engineers and thermal engineering researchers, this book can also be used by graduate level students and lecturers in the field.

Renewable Energy by Mansour Al Qubeissi,Ahmad El-Kharouf,Hakan Serhad Soyhan Pdf

The demand for secure, affordable and clean energy is a priority call to humanity. Challenges associated with conventional energy resources, such as depletion of fossil fuels, high costs and associated greenhouse gas emissions, have stimulated interests in renewable energy resources. For instance, there have been clear gaps and rushed thoughts about replacing fossil-fuel driven engines with electric vehicles without long-term plans for energy security and recycling approaches. This book aims to provide a clear vision to scientists, industrialists and policy makers on renewable energy resources, predicted challenges and emerging applications. It can be used to help produce new technologies for sustainable, connected and harvested energy. A clear response to economic growth and clean environment demands is also illustrated.
