ASHRAE Handbook

The ASHRAE Handbook is the four-volume flagship publication of the nonprofit technical organization ASHRAE (formerly American Society of Heating, Refrigerating and Air-Conditioning Engineers). This Handbook is considered the practical repository of knowledge on the various topics that form the field of heating, ventilation, air-conditioning, and refrigeration (HVAC&R). The four volumes are Fundamentals, Refrigeration, HVAC Applications (“Applications”), and HVAC Systems and Equipment (“Systems and Equipment”). Members of ASHRAE receive the current volume, in both print and CD-ROM form, each year as a basic membership benefit. An enhanced electronic version, known as ASHRAE Handbook Online is a web-based version updated annually that contains the four latest volumes as well as extra content such as calculations, demonstration videos, and spreadsheets. The various versions of the Handbook are typically available to the public via technical, and other, libraries and bookstores.
