'ASHRAE Handbook 2023 - HVAC Applications' Now Available

International. This year the edition consists of 67 chapters on various topics and installations, making it the largest volume published so far.

The purpose of the 'ASHRAE 2023 Handbook - HVAC Applications' is to provide industry professionals with reference material on the design and use of equipment and systems, some of which have been described in previous volumes of the book.

The main sections cover general, comfort, industrial, energy, operational and building management applications. ASHRAE technical committees reviewed each chapter, based on technological relevance and current design practices.

New chapters

• Chapter 23: Fire and EMT Stations and Training Academies. It outlines best practices for conditioning and ventilating these vital facilities.
• Chapter 66: Air Purifiers in Rooms It covers the use of room filtration to address air pollutants, with special emphasis on pathogen removal.
