Download or read book Low GWP A2L Refrigerant Safety written by Jason Obrzut, CMHE and published by ESCO Institute. This book was released on 2021-02-22 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Refrigeration units in marine vessels written by Prof. Dr.-Ing. A. Hafner and published by Nordic Council of Ministers. This book was released on 2019-04-02 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing vessels can be equipped with energy efficient refrigeration technology applying natural working fluids. Ammonia refrigeration systems have been the first choice, but CO2 units have also become increasingly common in the maritime sector in the last few years. When retrofitting or implementing CO2 refrigeration plants, less space on board is required and such units allow good service and maintenance. Nowadays, cruise ship owners prefer CO2 units for the provision refrigeration plants.Ship owners, responsible for the health and safety of the crew and passengers, must carefully evaluate the usage of flammable low GWP working fluids, due to a high risk that toxic decomposition products are formed, even without the presence of an open flame. Suggestions for further work include a Nordic Technology Hub for global marine refrigeration R&D and development support for key components.

Download or read book EPA 608 Study Guide written by Hvac Training 101 and published by . This book was released on 2019-12-06 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Refrigeration Air Conditioning and Heat Pumps written by Fabio Polonara and published by MDPI. This book was released on 2021-02-11 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Refrigeration, air conditioning, and heat pumps (RACHP) have an important impact on the final energy uses of many sectors of modern society, such as residential, commercial, industrial, transport, and automotive. Moreover, RACHP also have an important environmental impact due to the working fluids that deplete the stratospheric ozone layer, which are being phased out according to the Montreal Protocol (1989). Last, but not least, high global working potential (GWP), working fluids (directly), and energy consumption (indirectly) are responsible for a non-negligible quota of greenhouse gas (GHG) emissions in the atmosphere, thus impacting climate change.

Download or read book Concise Handbook of Fluorocarbon Gases written by Sina Ebnesajjad and published by John Wiley & Sons. This book was released on 2021-03-09 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes fluorocarbons gases’ preparation process, properties, applications and their evolution over time. The impact of fluorocarbons on the ozone layer and global and the development to mitigate those effects have been specially emphasized. The first major industrial fluorinated compound was developed in the 1920’s, to replace ammonia and sulfur dioxide refrigerants, at the General Motors Frigidaire Division by Thomas Midgley, Jr. and Albert Leon Henne. They developed a family of fluorocarbons trademarked Freon® for auto air conditioning units revolutionizing the auto industry. Other applications were developed over time including fire extinguishers, propellants, blowing agents, cleaners, anesthesia, artificial blood and others impacting every facet of life. In spite of being in broad global use for nearly a century, fluorocarbon gases have gone through great evolution during the last few decades. In the 1980s it was discovered chlorofluorocarbon (CFC) gases are harmful to the ozone layer, mainly because of their chlorine content. Chlorine was released in the upper atmosphere when chlorofluorocarbon molecules were broken down by the high energy cosmic radiation. CFCs were progressively banned following the Montreal Protocol of 1987. CFCs were replaced by fluorinated gases containing either less chlorine (hydrofluoro-chlorocarbons, or HCFCs), which are much less damaging (about 90% less) to the ozone layer or with fluorinated gases containing no chlorine, i.e. hydrofluorocarbons or HFCs. HFC have no impact on the ozone layer but impact global warming detrimentally. HFCs are usable without need for changes to the existing refrigeration or air conditioning installations. More recently hydrofluoroolefins (HFOs), which have little or no negative impact on global warming, have been developed to replace or reduce the use of HFCs. HFOs are used as single compounds or in blends. Research and development continues to develop and replace the HCFCs and HFCs completely with environmentally friendly products. Concise Handbook of Fluorocarbon Gases presents a reference and text for the commercial fluorocarbon gases which have great many application in a wide range of industries such as refrigeration and air conditioning, as well as consumer products.
