Uncomplicating The Heat Pump: Refrigeration and Air Flow Systems By Jim Johnson
$79.95
A DVD/CD HVACR Technician Training Package. This 90-minute video training program is designed to both eliminate the mystery behind heat pump refrigeration systems and explain charging procedures. Written and presented by well-known author and instructor Jim Johnson, it is appropriate for both new and experienced technicians. Jim shows cutaways to explain the fundamentals, then shows how to access heat pump refrigeration systems and use manufacturer's charging charts and temperature/pressure charts to evaluate both R-22 and R-410A systems. Troubleshooting procedures related to heat pump refrigeration and air flow systems are discussed. The accompanying self-print CD contains the interactive resource guide and quiz questions, making the program suitable for both self-paced learning and an instructor-led environment. ..Heating, Cooling & Defrosting Refrigerant Flow ..Heat Pump Refrigeration System Components ..Adjusting TXV's For Proper Superheat ..Subcooing In Heat Pumps ..Air Flow In Heat Pumps ..Evaluation & Troubleshooting

Centrifugal Pumps
$279.00
This book gives an unparalleled, up-to-date, in-depth treatment of all kinds of flow phenomena encountered in centrifugal pumps including the complex interactions of fluid flow with vibrations and wear of materials. The scope includes: all aspects of hydraulic design, 3D-flow phenomena and partload operation, cavitation, numerical flow calculations, hydraulic forces, pressure pulsations, noise, pump vibrations (notably bearing housing vibration diagnostics and remedies), pipe vibrations, pump characteristics and pump operation, the effects of highly viscous flows, pumping of gas-liquid mixtures, hydraulic transport of solids, fatigue damage to impellers or diffusers, material selection under the aspects of fatigue, corrosion, erosion-corrosion or hydro-abrasive wear, pump selection, and hydraulic quality criteria. To ease the use of the information, the methods and procedures for the various calculations and failure diagnostics discussed in the text are gathered in more than 100 pages of tables which may be considered almost unique in the open literature. The text focuses on practical application in the industry and is free of mathematical or theoretical ballast. In order to find viable solutions in practice, the physical mechanisms involved should be thoroughly understood. The book is focused on fostering this understanding which will benefit the pump engineer in industry as well as academia and students.

Troubleshooting & Serving Heat Pumps
$29.95
Being that this is the only service/repair book out on heat pumps reasonably priced there aren't many alternatives so we're stuck. I read it in about an hour - there's not much to it and no helpful tips that made me go "Wow - what a great idea!" It could use a chapter on installation and some explanations of the tradeoffs that can be made to optimize heat pump efficiency or operation. I'll give you a tip and I won't charge $30 either. Delay the indoor fan for 30 seconds to give the coil time to heat up so cold air doesn't blow out the vents.

Troubleshooting Centrifugal Pumps and Their Systems
$185.00
Pumps are fine until they malfunction or break down. When that happens, the first priority is to get the pump functioning again and to keep 'down time' to a minimum. Many problems can be diagnosed and rectified using a combination of knowledge and experience, the latter coming over time. This book, written by a very experienced engineer, guides the reader through diagnostic pathways leading to logical explanations for the malfunctions and their correction.
