The ASHRAE Handbook is published in a series of four volumes, one of which is revised each year, ensuring that no volume is older than four years. The new edition, incorporating a wide range of updates, is now available.
The handbook published by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), is considered a practical repository of knowledge in the heating and cooling sector. The edition covers in particular the areas of cooling, freezing and storing food; industrial applications; 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."
Out of a number of chapters that have been updated, the most interesting are:

Out of a number of chapters that have been updated, the most interesting are:
- 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 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 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.
