This book was released on 1981 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different flow patterns are encountered in the calandria of a climbing film evaporator when the feed is introduced cold. The lower part where the feed is brought to boiling temperature is filled with liquid. The remainder of the tube where evaporation occurs contains liquid and vapor phases. The local heat transfer coefficient and temperature profile were investigated separately for the liquid zone present in the lower part and for the boiling zone present in the upper part of a single tube glass evaporator. A study of the heat transfer in the liquid zone, where the process liquid is brought to its boiling temperature, showed that the presence of dissolved gases affects appreciably the efficiency when the operation is carried out under vacuum as compared to an operation at atmospheric pressure. In the boiling zone where two phase-flow is present (liquid and vapor phases), a heat transfer study permits the correlation of the pressure in the tube with the evaporating rate and the position along the evaporator tube. A model to determine the position where boiling begins, the temperature at any position in the tube, the vapor rate and the void fraction at the exit of the evaporator tube given the initial conditions (feed rate, feed temperature, vacuum in the system and thermal properties of the feed) was set up. Its validity was demonstrated by the results obtained with sugar solutions and tomato juice. The model was also successfully applied to an industrial scale example.

Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. Solar cooling is most effective where it is most needed - in the tropics. Most developing countries lie in the hotter climatic regions, where cooling facilities are essential to promote the well-being, productivity and comfort of the population. Paradoxically, solar air-conditioning can contribute significantly to the alleviation of the problem. This book includes fully detailed treatment of the theory and applications of the techniques involved: vapour absorption systems, solar absorption systems, solar absorption cooling, radiative cooling and desiccant cooling. Particular applications stressed include the use of passive cooling in buildings and the provision of efficient refrigeration facilities, the latter being essential for the storage of vaccines in health-care programmes for the eradication of infectious diseases throughout the developing world.

Available in PDF, EPUB and Kindle. Book excerpt: 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
