مقدمة  الكتاب  

The 2016 ASHRAE Handbook—HVAC Systems and Equipment

discusses various systems and the equipment (components or

assemblies) they comprise, and describes features and differences.

This information helps system designers and operators in selecting

and using equipment. ASHRAE Technical Committees in each subject

area have reviewed all chapters and revised them as needed for

current technology and practice. 

Some of the volume’s revisions and additions are as follows:

• 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 12, District Heating and Cooling, has new content from

ASHRAE research project RP-1267 (the new District Heating

Guide and District Cooling Guide).

• Chapter 18, Variable Refrigerant Flow, has new sections on modeling

and system commissioning, and an updated system design

example.

• Chapter 19, Duct Construction, has extensive revisions on system

leakage and air dispersion systems.

• 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 24, Desiccant Dehumidification and Pressure-Drying

Equipment, has expanded content on applications, air filters, and

liquid strainers, plus recommendations from ASHRAE research

project RP-1339 on rating equipment at altitude.

• 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 29, Air Cleaners for Particulate Contaminants, has updates

on standards and performance testing.

• Chapter 31, Automatic Fuel-Burning Systems, has added content

on pneumatically and electronically linked gas/air ratio burner

systems.

• Chapter 33, Furnaces, has updates for current technology and efficiency

requirements.

• 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 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 new content 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 pressureindependent

control valves.

• Chapter 49, Unitary Air Conditioners and Heat Pumps, has a new

map of U.S. regional appliance efficiency standards.

• Chapter 50, Room Air Conditioners and Packaged Terminal Air

Conditioners, has updates for efficiency standards.

• Chapter 51, Thermal Storage, has new content on grid reliability,

renewable power integration, heat storage, emergency cooling,

water treatment, and commissioning.

This volume is published, as a bound print volume and in electronic

format on CD-ROM and online, in two editions: one using

inch-pound (I-P) units of measurement, the other using the International

System of Units (SI).
