Preface

The 2010 ASHRAE Handbook-Refrigeration covers the refrigeration equipment and systems for applications other than human comfort. This book includes information on cooling, freezing, and storing food; industrial applications of refrigeration; and low-temperature refrigeration. Primarily a reference for the practicing engineer, this volume is also useful for anyone involved in cooling and storage of food products.

An accompanying CD-ROM contains all the volume's chapters in both I-P and SI units.

This edition includes 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. The chapter contains discussion and diagrams on CO2 refrigerant applications, system design, equipment, safety, lubricants, commissioning, operation, and maintenance.

• Chapter 50, Terminology of Refrigeration, lists some of the common terms used in industrial refrigeration systems, particularly systems using ammonia as the refrigerant.

Also new for this volume, chapter titles, order, and groupings have been revised for more logical flow and use. Some of the other revisions and additions are as follows:

• 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.

This volume is published, both as a bound print volume and in electronic format on a CD-ROM, in two editions: one using inchpound (I-P) units of measurement, the other using the International System of Units (SI).
