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).
