“The 2014 ASHRAE Refrigeration Handbook continues to provide the practicing refrigeration engineer with the data and information necessary to safe and efficient processing and storage of food and pharmaceuticals but the Handbook is evolving,” said Dan Dettmers, volume chair. “With the industry’s growing interest in the category of ‘natural’ refrigerants, the dedicated technical committees have updated the Handbook chapters on ammonia and carbon dioxide refrigeration systems. These chapters, traditionally focused on industrial systems, are finding new fans in the commercial realm as zero ozone depletion potential/global warming potential refrigerants are requested by our customers.”

Some updates and changes to the 2014 volume include the reworking of insulation tables in Chapter 10, Insulation Systems for Refrigerant Piping, to comply with ASTM Standard C680-10. Also, ASHRAE says an extensive reorganization was done for chapter 2, Ammonia Refrigeration Systems, to reflect current practices.

New sections on additives and process chemicals were included, as well as the addition of moisture isotherm data for R-290 and R-600a.

The ASHRAE Handbook is published in two editions: inch-pound (I-P) units of measurement and the International System of Units (SI). For more information, visit www.ashrae.org/bookstore.
