“Nearly 90% of the chapters have undergone revision since the 2012 volume was published,” Forrest Yount, volume chair, said. “That means there is a lot of new material for users to become familiar with. Many chapters have incorporated the results of recent research projects funded by ASHRAE.”
The volume contains two major updates to chapters. Chapter 12, District Heating and Cooling, has new content from ASHRAE research project RP-1267 (the new District Heating Guide and District Cooling Guide), while Chapter 51, Thermal Storage, has new content on grid reliability, renewable power integration, heat storage, emergency cooling, water treatment and commissioning.
Updates also include Chapter 49, Unitary Air Conditioners and Heat Pumps – new information on US regional appliance efficiency standards.
