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 Automotive Air Conditioning Refrigerant Service Guide written by Philip G Gott and published by SAE International. This book was released on 1996-07-01 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Packed with information on the servicing and retrofitting of air-conditioning refrigerant systems so that shops and technicians can meet federal regulations, satisfy customers, and prevent damage to the environment. The second edition of the Automotive Air-Conditioning Refrigerant Service Guide was written to provide the latest information to automotive air-conditioning service professionals in order to help them comply with federal certification requirements and prevent damage to the environment. With an emphasis on proper recovery and recycling techniques for both R-12 and R-134a, as well as the proper retrofitting of R-12 systems to R-134a, the book will serve as a valuable instructional tool and resource for technicians. Chapters cover: General Safety and Service Precautions; Refrigerant and System Properties; Equipment for the Extraction-only of Refrigerant and Equipment for the Recycling of Refrigerant; Service Procedure for the Containment of Automotive Air-Conditioning Refrigerants; Retrofitting CFC-12 (R-12) Mobile Air-Conditioning Systems to HFC-134a (R-134a).

Download or read book Safety Standards for Motor Vehicle Refrigerant Vapor Compression Systems written by Interior Climate Control Vehicle OEM Committee and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Standard applies to refrigerant vapor compression systems that provide cooling and/or heating for passenger cars, light trucks and commercial vehicles (on and off road) that use automotive type mobile air conditioning [MAC] systems. Large trucks, buses and other vehicles that do not use typical automotive a/c systems or use refrigerants not listed in this document are not covered by this standard. This standard covers any vehicle with a MAC system using a belt or electric motor driven compressor.This document provides standards for design, assembly, test and service of MAC systems to minimize environmental, health and safety impacts. Also included are cautionary statements for the service industry to alert technicians to the inadvisability and possible health or safety effects associated with venting refrigerant during service. It is not intended to restrict the use, or further development, of other types of refrigeration systems for mobile air conditioning applications. This document may be amended or additional safety standards created should other systems become practical. This document addresses only HFC-134a (R-134a), carbon dioxide (R-744), and HFO-1234yf (R-1234yf) refrigerants. To prevent system contamination all refrigerants used in mobile air conditioning vapor compression systems require unique service fittings and service equipment. The unique service fittings are intended to eliminate the potential for system refrigerant cross-contamination during service activity.CFC-12 (R-12) is no longer in use in new MAC systems. The service fitting description is maintained as a reference for older vehicles still in use. When retrofitting an R-12 system to use R-134a or when removing R-12 (vehicle disposal) use service equipment designed for R-12 and certified to meet the requirements of SAE J1990 (R-12 recovery and recycle equipment).HFC-152a is an A2 flammable refrigerant as classified by ASHRAE 34 and should be used only with a secondary loop application. However, until MAC systems are developed to use R-152a (HFC-152a), no SAE Standards for system design, service equipment or service procedures have been established. The R-152a service fittings described within this Standard were established as part of the industries evaluation of replacement refrigerants and are maintained for future design guidance and to prevent potential refrigerant cross contamination. This document covers refrigerant system design and safety related requirements for refrigerants used in mobile air conditioning (MAC) systems and is being revised to comprehend R-1234yf. The current wording of 4.1.1 prohibits refrigerants that are rated less than A2L which would exclude R-152a. Later in the document, J639 defines the fittings for R-152a. The intent of this revision is to insure safe mobile air conditioning systems by forcing proper risk assessments and appropriate design solutions while correcting this conflict with regards to R152a.

The revisions in this document cover engineering guidelines and establishing specifications for mobile air conditioning systems using current and alternate replacement refrigerants. R 1234yf is added here for the first time.
Download or read book Refrigeration Air Conditioning and Heat Pumps Technical Options Committee 2002 written by United Nations Environment Programme and published by UNEP/Earthprint. This book was released on 2003-09 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2002 assessment report, produced under the Montreal Protocol on ozone depleting substances, finds that technical progress has been made by the refrigeration, air conditioning and heat pump industry to comply with requirements to phase out CFCs and in several applications, HCFCs as well. However, there is still a significant amount of installed refrigeration equipment still using CFCs and HCFCs, and so service demand remains high and is best minimised by preventive service, containment, retrofit, recovery and recycling.

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.
