The 2023 ASHRAE Handbook\u2014HVAC Applications comprises more than 65 chapters covering a broad range of facilities and topics, written to help engineers design and use equipment and systems described in other Handbook volumes. Main sections cover comfort, industrial, energy-related, general applications, and building operations and management. ASHRAE Technical Committees in each subject area have reviewed all chapters and revised them as needed for current technology and design practice. This volume has been extensively revised, and boasts two new chapters on facilities for emergency medicine and firefighters, and on in-room air cleaners.<\/p>\n
