McLinden* and Marcia L. Huber Cite This: J. Chem. Eng. Data 2020, 65, 4176−4193 Read Online ACCESS Metrics & More Article Recommendations *sı Supporting Information ABSTRACT: As we enter the “fourth generation” of refrigerants, we consider the evolution of refrigerant molecules, the ever- changing constraints and regulations that have driven the need to consider new molecules, and the advancements in the tools and property models used to identify new molecules and design equipment using them. These separate aspects are intimately intertwined and have been in more-or-less continuous development since the earliest days of mechanical refrigeration, even if sometimes out-of-sight of the mainstream refrigeration industry. We highlight three separate, comprehensive searches for new refrigerantsin the 1920s, the 1980s, and the 2010sthat sometimes identified new molecules, but more often, validated alternatives already under consideration. A recurrent theme is that there is little that is truly new. Most of the “new” refrigerants, from R-12 in the 1930s to R- 1234yf in the early 2000s, were reported in the chemical literature decades before they were considered as refrigerants. The search for new refrigerants continued through the 1990s even as the hydrofluorocarbons (HFCs) were becoming the dominant refrigerants in commercial use. This included a return to several long-known natural refrigerants. Finally, we review the evolution of the NIST REFPROP database for the calculation of refrigerant properties. -

Three Bond Technical News Issued Dec. 20, 1989 An Overview of Fluorocarbons Introduction Currently, chlorofluorocarbons are garnering a lot of Three Bond Co,. Ltd. has been working night and day in attention around the world. Chlorofluorocarbons are used in search of alternatives to chlorofluorocarbons. In the future, many of our products and when we look at the future of products that do not contain any chlorofluorocarbons will chlorofluorocarbons in the world, and in Japan, we can replace products that now contain chlorofluorocarbons. To foresee that their use will be strictly limited or eliminated all ensure these products reach our customers as smoothly as together. possible, it is important that they have a good understanding of the issues surrounding chlorofluorocarbons. Whatever the case, Three Bond Co., Ltd. is obligated to provide our customers with products that have the same functionality as chlorofluorocarbons.

OCCUPATIONAL EXPOSURE TO DECOMPOSITION PRODUCTS of FLUOROCARBON POLYMERS U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Public Health Service Center for Disease Control National Institute for Occupational Safety and Health September 1977 For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 DHEW (NIOSH) Publication No. 77-193 PREFACE The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and safety of workers exposed to an ever-increasing number of potential hazards at their workplace. The National Institute for Occupational Safety and Health has projected a formal system of research, with priorities determined on the basis of specified indices, to provide relevant data from which valid criteria for effective standards can be derived. Recommended standards for occupational exposure, which are the result of this work, are based on the health effects of exposure. The Secretary of Labor will weigh these recommendations along with other considerations such as feasibility and means of implementation in developing regulatory standards. It is intended to present successive reports as research and epidemiologic studies are completed and as sampling and analytical methods are developed. Criteria and standards will be reviewed periodically to ensure continuing protection of the worker. I am pleased to acknowledge the contributions to this report on the decomposition products of fluorocarbon polymers by members of the NIOSH staff and the valuable constructive comments by the Review Consultants on the Decomposition Products of Fluorocarbon Polymers and by Robert B. -
Inventory of US Greenhouse Gas Emissions and Sinks: 1990-2015
ANNEX 6 Additional Information 6.1. Global Warming Potential Values Global Warming Potential (GWP) is intended as a quantified measure of the globally averaged relative radiative forcing impacts of a particular greenhouse gas. It is defined as the cumulative radiative forcing–both direct and indirect effectsintegrated over a specific period of time from the emission of a unit mass of gas relative to some reference gas (IPCC 2007). Carbon dioxide (CO2) was chosen as this reference gas. Direct effects occur when the gas itself is a greenhouse gas. Indirect radiative forcing occurs when chemical transformations involving the original gas produce a gas or gases that are greenhouse gases, or when a gas influences other radiatively important processes such as the atmospheric lifetimes of other gases. The relationship between kilotons (kt) of a gas and million metric tons of CO2 equivalents (MMT CO2 Eq.) can be expressed as follows: MMT MMT CO2 Eq. kt of gas GWP 1,000 kt where, MMT CO2 Eq. = Million metric tons of CO2 equivalent kt = kilotons (equivalent to a thousand metric tons) GWP = Global warming potential MMT = Million metric tons GWP values allow policy makers to compare the impacts of emissions and reductions of different gases. According to the IPCC, GWP values typically have an uncertainty of 35 percent, though some GWP values have larger uncertainty than others, especially those in which lifetimes have not yet been ascertained. In the following decision, the parties to the UNFCCC have agreed to use consistent GWP values from the IPCC Fourth Assessment Report (AR4), based upon a 100 year time horizon, although other time horizon values are available (see Table A-263). -
