Many cooling systems use water as cooling medium. They are found in public buildings, industrial production systems or power plants. Almost every cooling system using water is degraded by deposition, corrosion and microbiological fouling. This book identifies the whole bunch of problems due to water cooling systems and proposes specific solutions to all of them. The authors have an expertise of over 20 years solving cooling water problems. In this book, they advise all practitioners which need to plan, buy or operate cooling systems.
Do It Yourself installation instructions for installing a geothermal heat pump's horizontal earth loop. Ten years ago geojerry learned about the problems that contractors have with installing geothermal heat pumps and is trying to educate the potential geothermal customer so they can get a correctly sized, designed, and installed geothermal heat pump system. Here are the chapters in the book; Page 9 Chapter One Be Smart And Do Not Guess What Size Earth Loop You Need Page 12 Chapter Two Horizontal Loop Location And Layout Page 17 Chapter Three Horizontal Loop Trench Excavation Page 23 Chapter Four Installing A Slinky Earth Loop Page 29 Chapter Five Installing The Earth Loop Soaker Line Page 31 Chapter Six Basement Wall Penetration Page 34 Chapter Seven Earth Loop Floor Or Slab Penetration Page 40 Chapter Eight Installing Earth Loop Manifolds Inside The Basement Page 45 Chapter Nine Pressure Testing For Leaks Page 49 Chapter Ten Backfilling The Trenches Page 52 Chapter Eleven Connecting Your Earth Loop Manifolds To Your Circulating Pump/s Or Flow Center AND To Your Geothermal Heat Pump Page 56 Chapter Twelve How To Flush And Fill Your Earth Loop And Add Propylene Glycol Antifreeze To It Page 63 Chapter Thirteen How To Pressurize Your Earth Loop Page 70 Chapter Fourteen How To Calculate The Energy Efficiency Of Your Geothermal Heat Pump... Calculating The COP And The EER Of Your Geothermal Heat Pump This book does not tell the DIY customer how to size and/or design the horizontal earth loop, but it has the information needed to get their horizontal earth loop correctly installed. It has instructions for the installation of one pipe per trench earth loop or a slinky earth loop. Geojerry has sized and designed thousands of earth loops for geothermal heat pump systems and you can get your complete system sized and designed at geojerry.com
This book supports HVAC planners in reducing the cooling energy demand, improving the indoor environment and designing more cost-effective building concepts. High performance buildings have shown that it is possible to go clearly beyond the energy requirements of existing legislation and obtaining good thermal comfort. However, there is still a strong uncertainty in day-to-day practice due to the lack of legislative regulations for mixed-mode buildings which are neither only naturally ventilated nor fully air-conditioned, but use a mix of different low-energy cooling techniques. Based on the findings from monitoring campaigns (long-term measurements in combination with field studies on thermal comfort), simulation studies, and a comprehensive review on existing standards and guidelines, this book acts as a commonly accessible knowledge pool for passive and low-energy cooling techniques.
The Aubin Academy Master Series: AutoCAD MEP is a concise manual focused squarely on the rationale and practicality of the AutoCAD MEP process. The book emphasizes the process of creating projects in MEP rather than a series of independent commands and tools. The goal of each lesson is to help the reader complete their projects successfully. Tools are introduced together in a focused process with a strong emphasis on "why" as well as "how." The text and exercises seek to give the reader a clear sense of the value of the tools, and a clear indication of each tool's potential. The Aubin Academy Master Series: AutoCAD MEP is a resource designed to shorten your learning curve, raise your comfort level, and, most importantly, give you real-life tested practical advice on the usage of the software to create mechanical, electrical, and plumbing designs, and calculations. Empowered with the information within this book, the reader will have insight into how to use AutoCAD MEP to create construction documents that are reflective of their standards and expectations. ***This edition is designed takes the core version 2012 text and makes it compatible with version 2013 by providing a 2013 format dataset download and noting differences where they occur. This book is fully compatible with version 2012, 2013 and beyond. Visit paulaubin.com for free downloads and PDF chapters***
2012 Reprint of 1959 Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. This manual is written especially to enable pipefitters to quickly solve problems involving pipe bending, layout or installation, either in shop or in the field. This second edition has 126 pages of additional material than published in the previous edition of 1953. A large part of the book is taken directly from the author's original tables which he has developed over a long period of time, as a result of his 35 years' experience as a pipefitter. These tables eliminate the necessity for making lengthy calculations by giving immediate answers to all kinds of pipe fitting problems. Information on: Pipe Bending, Offsets, Mitered Joints, Standard Pipe Dimensions and Thread Data, Screwed Fittings, Valves, Solder Joint Fittings, Plastic Pipe, Sheet Metal Data, Properties of Steam, Melting Points, Conversion Factors and a Dictionary Of Terms.
Air conditioning boosts man's efficiency no less than his comfort. Air-conditioned homes, offices, and factories unmistakably raise human productivity and reduce absenteeism, turnover, mistakes, accidents and grievances, especially in summer. Accordingly, many employers every year cool workrooms and offices to raise summer profits. Employees in turn find cool homes enhancing not only comfort and prestige but also personal efficiency and income. With such economic impetus, low-cost summer cooling must irresistibly spread to all kinds of occupied buildings. Refrigeration provides our best cooling, serving well where people are closely spaced in well-constructed, shaded, and insulated structures. However, its first and operating costs bar it from our hottest commercial, industrial, and residential buildings. Fortunately, evaporative cooling is an economical substitute in many regions. First used in Southwest homes and businesses and in textile mills, it soon invaded other fields and climates. In 1946, six firms produced 200,000 evaporative coolers; in 1958, 25 firms produced 1,250,000, despite the phenomenal sale of refrigerating window air conditioners. Though clearly secondary to refrigeration, evaporative cooling is 60 to 80 percent is economical for moderate income groups and cheaper to buy and operate. Thus, it climates where summers are short. Moreover, it cheaply cools hot, thinly constructed mills, factories, workshops, foundries, powerhouses, farm buildings, canneries, etc., where refrigerated cooling is prohibitively expensive.
