July 8, 2010: Updated ASHRAE Handbook Provides Information on Refrigeration

ATLANTA - The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has announced the availability of the 2010 ASHRAE Handbook – Refrigeration, which covers refrigeration equipment and systems for applications including cooling, freezing, and storing food; industrial applications of refrigeration; and low-temperature refrigeration.

“The Handbook gives the industry a primer in a wide variety of refrigeration topics, such as storing and transporting fruit, cryosurgery, ice-skating rinks, slaughterhouses and concrete dams,” said William McCartney, chair of the committee that oversaw writing of the volume. “While the Handbook is primarily a reference for the practicing engineer, the volume is also useful for anyone involved in cooling and storage of food products.”

The volume contains two new chapters: Chapter 3, Carbon Dioxide Refrigeration Systems, describes the history of this “natural refrigerant” and why it is the subject of renewed interest today; and Chapter 50, Terminology of Refrigeration, lists common terms used in industrial refrigeration systems.

Other changes include:

• Chapter 2, Ammonia Refrigeration Systems, has added guidance on avoiding hydraulic shock, on purging water and noncondensables, as well as on hot-gas defrost and defrost control.

• Chapter 6, Refrigerant System Chemistry, has added information on polyvinyl ether (PVE) lubricants and corrosion, plus updates for recent ASHRAE research on copper plating and material compatibility.

• Chapter 8, Equipment and System Dehydrating, Charging, and Testing, has new table data on dehydration and moisture-measuring methods and a revised section on performance testing.

• Chapter 9, Refrigerant Containment, Recovery, Recycling and Reclamation, has added a new table comparing sensitivities of various leak-detection methods and a procedure for receiver level monitoring.

• Chapter 11, Refrigerant-Control Devices, has updated information on electric expansion valves and discharge bypass valves, plus revised figures on thermostatic expansion valves (TXVs) and several revised examples.

• Chapter 12, Lubricants in Refrigerant Systems, has new content on pressure/viscosity coefficients, compressibility factors and lubricants’ effects on system performance.

• Chapter 17, Household Refrigerators and Freezers, has been reorganized and updated for revised standards and new component technologies, including variable-speed and linear compressors, and has information on new configurations and functions, such as wine cooling units, rapid-chill/freeze/thaw and odor elimination. The section on performance evaluation has been revised and integrated with the section on standards.

• Chapter 25, Cargo Containers, Rail Cars, Trailers, and Trucks, has been updated with information on multitemperature compartments and air curtains.

• Chapter 38, Fruit Juice Concentrates and Chilled Juice Products, has added description of storage tank sterilization.

• Chapter 44, Ice Rinks, has extensive changes to the section on heat recovery and updated loads information based on ASHRAE research project RP-1289.

The cost of the 2010 ASHRAE Handbook – Refrigeration, which includes the CD, is $195, in inch-pound (I-P) or the International System of Units (SI). The 2010 ASHRAE Handbook on CD, which contains both the I-P and SI editions, costs $155.

To order, contact ASHRAE Customer Service at 800-527-4723 (United States and Canada) or 404-636-8400 (worldwide), fax 404-321-5478, or visit www.ashrae.org/bookstore.
