Compressed air has many applications in industry. Delivering compressed air to a manufacturing facility is an expensive operation and it requires costly equipment that consumes significant amounts of electricity and needs frequent maintenance. Roughly 80 to 90 percent of the electricity used to operate compressed air systems is converted to low-temperature waste heat. This lost energy can quickly add up, each year costing individual facilities as much as double the purchase and installation cost (first-cost) of the entire system. The ideal time to think about your compressed air system is before it is installed.Air Compressors deserve independent treatment due to many reasons. There is a wider choice of different types of compressor designs each operating at different efficiencies and suitable for specific application. The type of compressor decided upon has direct implications on the lifetime energy costs. Also the decision as to a single compressor of large capacity versus multi-compressor installation where each compressor has a smaller capacity than the demand influences the possible energy savings considerably. This 6 -hour Quick Book Course provides comprehensive information on the compressed air systems. This course is relevant to anyone needing to know more about compressed air production and use, relevant health and safety issues, legislation and energy efficiency. Previous knowledge of the subject is not required.The book includes a multiple type quiz comprising 30 questions at the end. Learning ObjectiveAt the conclusion of this course, the student will: * Understand various types of compressors; their applications, advantages and limitations; * Understand various types of system controls - their pros and cons; * Understand how the control systems are matched to the needs of the users; * Understand the key components of compressed air system and learn how each component function; * Understand the air storage, air drying, piping, filtration and air cleaning methods; * Understand the limits of dew point suppression in refrigerant and desiccant dryers; * Understand the different types of filters and how coalescing filters benefit in removal of lubricant and moisture; * Understand the difference between SCFM, ICFM and ACFM; * Understand the pros and cons of single loop verses ring main systems; * Understand how to quantify and select appropriate compressor for base and trim demand; * Understand what features to specify and what information to seek when making a compressed air proposal; * Understand the compressed air system assessment procedure and energy audit methodology; * Understand the common losses in compressed air systems and the ways to conserve energy; * Understand the routine maintenance schedule for air compressors; * Learn a generic checklist for energy efficiency in compressed air system; * Understand the engineering formulae and technical relationship between compressor motor power-draw and process variables; and * Learn by example the method for evaluating compressed air costs.

Compressed air systems are the third most important utility to industry and are commonly the most misunderstood. Written to appeal to operators, mechanics and junior engineers, this manual is designed to provide a solid understanding of common compression systems and operations techniques. Using this book, the users learn tips and techniques for: creating a baseline of system performance, determining the impact of different compressors and compressor control types for the job at hand, and learning basic approaches to general maintenance.

A "how-to" reference to help compressed air users and service providers improve the operating efficiencies and reliability of their air compressor and compressed air systems. The manual contains more than 300 pages original text, reference appendices, photos, and performance data.

Accepted as the standard reference work on modern pneumatic and compressed air engineering, the new edition of this handbook has been completely revised, extended and updated to provide essential up-to-date reference material for engineers, designers, consultants and users of fluid systems.

Althoughtheprinciplesofoperationofhelicalscrewmachines,ascompressors or expanders, have been well known for more than 100 years, it is only during the past 30 years that these machines have become widely used. The main reasons for the long period before they were adopted were their relatively poor e?ciency and the high cost of manufacturing their rotors. Two main developments led to a solution to these di?culties. The ?rst of these was the introduction of the asymmetric rotor pro?le in 1973. This reduced the bl- hole area, which was the main source of internal leakage by approximately 90%, and thereby raised the thermodynamic e?ciency of these machines, to roughly the same level as that of traditional reciprocating compressors. The second was the introduction of precise thread milling machine tools at - proximately the same time. This made it possible to manufacture items of complex shape, such as the rotors, both accurately and cheaply. From then on, as a result of their ever improving e?ciencies, high rel- bility and compact form, screw compressors have taken an increasing share of the compressor market, especially in the ?elds of compressed air production, and refrigeration and air conditioning, and today, a substantial proportion of compressors manufactured for industry are of this type. Despite, the now wide usage of screw compressors and the publication of many scienti?c papers on their development, only a handful of textbooks have been published to date, which give a rigorous exposition of the principles of their operation and none of these are in English.

This collection of papers from a prestigious IMechE conference looks at the latest innovations and techniques from experts in the field of rotating machinery from industry and academia. Reflecting latest developments in air, gas, refrigeration and related systems, these conference transactions will be of vital importance to all those equipment manufacturers, suppliers, users, and research organizations who wish to be well informed of developments and advances in this important field of engineering.
