Guideline 6 identifies the types of refrigerant data that may be required by product development and system design engineers, ASHRAE standards, and appropriate codes to successfully apply a refrigerant in refrigeration or air-conditioning equipment. It also provides refrigerant suppliers and researchers with examples of measurement methods, previous research, and desired accuracy levels for various refrigerant properties.
The 2015 edition of Guideline 6 includes new refrigerant product families that were not commercially used in the United States in 2008: hydrocarbons, hydrofluoro-olefins, and ethers. The commercial development of a new lower flammability Class 2L of refrigerants and blends introduces additional (optional) property information needed in ASHRAE Standards 34 and 15 and in risk assessments for various applications, such as burning velocity, autoignition temperature, minimum ignition energy, hot surface ignition temperature, and more stringent thermal and hydrolytic stability properties. System chemistry, refrigerant reactivity, and blend fractionation testing are covered in greater detail to reflect recent technology developments. CO2 subcritical and transcritical cycle applications were not covered in Guideline 6-2008, but they are covered in this edition due to renewed interest in “natural refrigerants” and concerns for global warming.
