ASHRAE 2016 Handbook Focuses on HVAC Systems and Equipment

ATLANTA, Ga. – Revisions to the majority of chapters, including major updates related to thermal storage and district heating and cooling, are included in the newly published 2016 ASHRAE Handbook – HVAC Systems and Equipment.

The volume discusses various systems and the equipment, components or assemblies they comprise. It describes features and differences, to help system designers and operators in selecting and using equipment.

“Nearly 90 percent 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.

Other updates that likely will impact many users include Chapter 19, Duct Construction,  extensive revisions on system leakage and air dispersion systems; Chapter 33, Furnaces, updates for current technology and efficiency requirements and Chapter 49, Unitary Air Conditioners and Heat Pumps, new information on U.S. regional appliance efficiency standards.
Other revisions and additions include:

• Chapter 7, Combined Heat and Power Systems, has a new section on economic evaluation and includes an update on EU Directive 2004/8/EC.
• Chapter 9, Applied Heat Pump and Heat Recovery Systems, has new content on waste heat recovery, district applications, and industrial process heat pumps.
• Chapter 18, Variable Refrigerant Flow, has new sections on modeling and system commissioning, and an updated system design example.
• Chapter 20, Room Air Distribution Equipment, has updates for current technology, with new information on specialized components and air curtains.
• Chapter 21, Fans, has new sections on series fan operation and field performance testing plus added content on fan and motor efficiency grades and parallel multiple-fan operation.
• Chapter 25, Mechanical Dehumidifiers and Related Components, has new content on psychrometrics, outdoor air, controls, and industrial dehumidifiers.
• Chapter 26, Air-to-Air Energy Recovery Equipment, has new information on heat pipes and desiccant and heat wheel systems.
• Chapter 28, Unit Ventilators, Unit Heaters, and Makeup Air Units, has revisions on standards, controls, and fan selection for makeup air units.
• Chapter 37, Solar Energy Equipment, has new data on worldwide solar technology use, plus an expanded section on photovoltaic equipment.
• Chapter 38, Compressors, has revisions on general theory; screw and scroll compressors; and bearings, including oil-free technologies.
• Chapter 43, Liquid-Chilling Systems, has revised content on refrigerant selection and global warming potential.
• Chapter 44, Centrifugal Pumps, has new content on vertical, inline, split-coupled pumps; hydronic system pump selection; and differential pressure control.
• Chapter 45, Motors, Motor Controls, and Variable-Frequency Drives, has updates on standards, bearing currents, and permanent-magnet motors.
• Chapter 47, Valves, has new content on control valve sizing; electronic actuators; and ball, butterfly, flow-limiting, and pressure-independent control valves.

The volume is being published in a bound print volume and in electronic format on a CD-ROM and online, in two editions: one using inch-pound units of measurement, the other using the International System of Units.

The new 2016 volume also is available as one of the four current volumes included in ASHRAE Handbook Online. Members can subscribe for $33 (list, $289) and get immediate, searchable access to all four volumes in both I-P and SI units.

The cost of the 2016 ASHRAE Handbook – HVAC Systems and Equipment print bound volume, which also includes the CD is $209, in I-P or SI. The 2016 ASHRAE Handbook CD, which contains both the I-P and SI editions, costs $189.
