Book Description
As the HVACR industry continues to move forward and innovate, the refrigerants that were once so commonplace are now being phased out. Replacing them are more energy efficient, environmentally friendlier refrigerants, known as Low GWP refrigerants. Many of these new refrigerants are classified by ASHRAE as A2L, or slightly flammable. The industry is also seeing expanded use of some hydrocarbon (A3) refrigerants, such as propane and isobutane. Students and technicians will require additional training for the safe handling and transportation of these refrigerants. The Low GWP refrigerant program manual covers: Refrigerant safety Introduction to Low GWP refrigerants Refrigerant properties and characteristics The refrigeration cycle Working with refrigerant blends Proper installation and service guidelines Flammable refrigerant considerations Explanation of the associated codes and standards for A2L refrigerants

Book Description
The definitive text/reference for students, researchers and practicing engineers This book provides comprehensive coverage on refrigeration systems and applications, ranging from the fundamental principles of thermodynamics to food cooling applications for a wide range of sectoral utilizations. Energy and exergy analyses as well as performance assessments through energy and exergy efficiencies and energetic and exergetic coefficients of performance are explored, and numerous analysis techniques, models, correlations and procedures are introduced with examples and case studies. There are specific sections allocated to environmental impact assessment and sustainable development studies. Also featured are discussions of important recent developments in the field, including those stemming from the author’s pioneering research. Refrigeration is a uniquely positioned multi-disciplinary field encompassing mechanical, chemical, industrial and food engineering, as well as chemistry. Its wide-ranging applications mean that the industry plays a key role in national and international economies. And it continues to be an area of active research, much of it focusing on making the technology as environmentally friendly and sustainable as possible without compromising cost efficiency and effectiveness. This substantially updated and revised edition of the classic text/reference now features two new chapters devoted to renewable-energy-based integrated refrigeration systems and environmental impact/sustainability assessment. All examples and chapter-end problems have been updated as have conversion factors and the thermophysical properties of an array of materials. Provides a solid foundation in the fundamental principles and the practical applications of refrigeration technologies Examines fundamental aspects of thermodynamics, refrigerants, as well as energy and exergy analyses and energy and exergy based performance assessment criteria and approaches Introduces environmental impact assessment methods and sustainability evaluation of refrigeration systems and applications Covers basic and advanced (and hence integrated) refrigeration cycles and systems, as well as a range of novel applications Discusses crucial industrial, technical and operational problems, as well as new performance improvement techniques and tools for better design and analysis Features clear explanations, numerous chapter-end problems and worked-out examples Refrigeration Systems and Applications, Third Edition is an indispensable working resource for researchers and practitioners in the areas of Refrigeration and Air Conditioning. It is also an ideal textbook for graduate and senior undergraduate students in mechanical, chemical, biochemical, industrial and food engineering disciplines.

Book Description
When installing or servicing an air conditioning or refrigeration system, two of the most important tasks performed by technicians are refrigerant recovery and system evacuation. In order to perform these tasks properly, and in a safe manner, technicians need to understand the theory behind them, having a working knowledge of the equipment and tools used, and employ accepted industry best practices. This e-book walks through each step of both tasks, while covering safety, theory, and application. Also covered are leak detection methods and filter drier use. System Recovery and Evacuation was written by HVACR instructors for HVACR instructors to provide sound, relevant information in a single source. This e-book provides students and practicing technicians with the information and knowledge necessary to understand refrigerant recovery, system evacuation, leak detection, and filter driers. It is full of color illustrations and includes worksheets that provide students and practicing technicians with the information and knowledge necessary to accurately and safely install or service air conditioning and refrigeration systems. The end of the e-book contains fill-in-the-blank questions that review the content of the entire manual.

Book Description
HVAC Training 101 is a site visited by over 100,000 enthusiasts monthly, who are interested in becoming HVAC technicians. The site initially began as the passion project of a retired HVAC technician. The site quickly gained popularity, building a strong community of aspiring HVAC technicians. Currently, it is managed by a team of ex-HVAC technicians with decades of experience in the industry. Head over to HVACTraining101.Com to learn more. We began by writing about how to become certified as an HVAC technician. With rules and certifications varying for each state, it was a challenging task. We had a few friends in other states help us out, but for some states, we had to dig really deep to find the information needed. Our audience at the time was very happy with the information we provided. At this point, we started getting many questions about EPA 608 certification. Once you get the education and experience needed to become a technician, prospective employers will ask for certification to handle refrigerants. When we started writing about how to become certified, viewers again requested we write a study guide to help them prepare for the 608 exams. The study guides out there were dense and had much more information than was needed to pass the test. This inspired us to embark on a journey to write the simplest study guide for the EPA 608 exam, which would still cover all the necessary information. We hope we have achieved our intended objective. The journey to becoming an HVAC technician can be long and arduous. We congratulate you on taking this path and wish you the best in cracking the EPA 608 exam.
