The ASHRAE Handbook is published in a series of four volumes which are “HVAC Systems and Equipment”, “HVAC Applications”, “Refrigeration”, and “Fundamentals”. One of the four volumes is revised each year, ensuring that no volume is older than four years. Each volume is available in I-P (Inch-Pound) or SI (System International) units of measurement.
