Book excerpt: Cooling Towers: Principles and Practice, Third Edition, aims to provide the reader with a better understanding of the theory and practice, so that installations are correctly designed and operated. As with all branches of engineering, new technology calls for a level of technical knowledge which becomes progressively higher; this new edition seeks to ensure that the principles and practice of cooling towers are set against a background of up-to-date technology. The book is organized into three sections. Section A on cooling tower practice covers topics such as the design and operation of cooling towers; types of cooling tower; cooling tower components and construction materials; practical aspects of tower selection; industrial applications; and water quality and treatment. Section B is devoted to cooling tower theory and calculations. These include psychrometry; heat transfer theory and calculations; calculations when selecting tower size for a given duty; and the use of charts for calculation of cooling tower duties. Section C on data and tables explains the basis of the SI system of units and includes meteorological tables and data as well as data on specific heat capacity of some common substances.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this years' work has been to test and analyze the new dry cooling tower surface previously developed. The model heat transfer test apparatus built last year has been instrumented for temperature, humidity and flow measurement and performance has been measured under a variety of operating conditions. Tower Tests showed approximately 40-50% of the total energy transfer as taking place due to evaporation. This can be compared to approximately 80 to 85% for a conventional wet cooling tower. Comparison of the model tower test results with those of a computer simulation has demonstrated the validity of that simulation and its use as a design tool. Computer predictions have been made for a full-size tower system operating at several locations. Experience with this counterflow model tower has suggested that several design problems may be avoided by blowing the cooling air horizontally through the packing section. This cross flow concept was built from the previous counterflow apparatus and included the design and fabrication of new packing plates. Instrumentation and testing of the counterflow model produced data with an average experimental error of 10%. These results were compared to the predictions of a computer model written for the cross flow configuration. In 14 test runs the predicted total heat transfer differed from the measured total heat transfer by no more than 8% with most runs coming well within 5%. With the computer analogy's validity established, it may now be used to help predict the performance of full scale wet-dry towers.

This book was released on 1975 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes research for the past year on methods to enhance the environmental and economic performance of dry cooling towers. The work has concentrated on dry cooling towers utilizing periodic water to air heat exchangers. Periodic towers have sheet metal discs partially submerged in hot, power plant condenser effluent. As the discs rotate, the discs alternately absorb heat from the effluent and discharge heat to the air. The means of heat transfer on the air side can be either evaporative and/or convective, depending upon the amount of effluent carried into the air side on the surface of the plates. An oil layer, floated on the water's surface, has been shown to be effective in eliminating water carry-over to the air side. The advantages of the periodic tower lie in the low cost of the discs and the ability to operate dry . A periodic tower should be significantly less expensive than a conventional dry tower fabricated with finned tubes. Further, since the periodic tower can also operate wet, by removing the oil film, the high capacity losses incurred during warm months by conventional dry towers can be eliminated. In the past year, tests on a 20 inch model of the periodic tower indicated that at operational speeds of the full sized disc, no noticeable churning of the oil layer occurred. Heat transfer rates measured with the 20 inch model were 20 percent higher than predicted by an approximate analysis. Finally, silicone oils' low vapor pressure make them superior to hydrocarbon oils on the basis of evaporation rates, but their higher costs and possible ecological impact necessitates a closer look at hydrocarbon oils. Construction of the full scale test facility is complete. Shaped, rigid five foot diameter discs have been designed, fabricated, and assembled into an initial test module. Instrumentation for heat transfer tests is also complete; including instrumentation for measuring disc temperatures, and both air and water flow rates and temperatures. A parametric study of the oil film thickness on the air side of the test module has been completed. Measured thicknesses were 20 percent less than that previously predicted. This thinner oil layer means an increase in the disc heat transfer. A test apparatus to study the further enhancement of disc performance by surface roughening has been constructed, instrumented and calibrated. The apparatus has reproduced experimental friction factor and heat transfer coefficient curves for flat plates, and will be used to evaluate enhancement as a function of rib shape, size, spacings and Reynold's number. Visits to several architectural engineers across the country were made with representatives of Air Preheater Company to gage their acceptance of the rotary concept. All felt that if the reliability of the rotary concept could be demonstrated and the costs were less than equivalent conventional dry towers, the rotary design would be the preferred choice. Based on these findings, Air Preheater is planning to do design and cost studies of the rotary concept for the coming year.

Available in PDF, EPUB and Kindle. Book excerpt: The machines and processes of industry, as well as the air-conditioning systems for buildings generate tremendous amounts of heat, which must be continuously, dissipated if these machines and processes are to continue to operate efficiency. Water cooling is the most efficient method of dissipating heat. A cooling tower is a device used in industry to cool hot water (by partial evaporation) before reusing it as a coolant. Water directly contacts surrounding air and a very small part (1-2%) evaporate. This evaporation increases the air temperature and humidity and decreases the temperature of the water making it possible to cool below the normal air temperature. Although this heat is usually transferred to a cool, flowing volume of water, final rejection is always to the atmosphere and, invariably, is accomplished by some form of heat exchanger. The amount of cooling that you get from a cooling tower depends on the relative humidity of the air and the barometric pressure. For example, the more humid the climate the lesser will be the temperature drop and vice versa. This 6 hours Quick Book provides comprehensive information on cooling water systems and describes different types of cooling towers, their mechanical components and the problems associated with cooling water. The student must take a multiple-choice quiz consisting of thirty five (35) questions at the end of this course to obtain PDH credits. Learning Objective At the conclusion of this course, the reader will: 1)Learn different types of heat rejection systems 2)Learn the operational theory and principles of evaporative cooling tower 3)Describe the factors affecting the performance of cooling tower 4)Learn the various materials used in construction of cooling tower 5)Understand the functions of various components of cooling tower 6)Describe various control options 7)Understand the layout and installation considerations 8)Understand the water distribution mechanisms, noise and vibration issues 9)Understand the cooling tower water balance 10)Learn the importance of cooling water treatment 11)Describe the cooling tower testing requirements, various codes and standards 12)Learn by examples the equations to calculate the evaporation rate, fresh water make up and blowdown requirements
