July 3, 2006: CO2 Refrigerant Guidance Added to ASHRAE Handbook
ATLANTA - Carbon dioxide (CO2) was used in the early stages of refrigeration but fell out of favor with the development of halocarbon refrigerants. Due to CO2's desirable environmental properties and relative safety, there is renewed interest in carbon dioxide as a refrigerant. Because of this, guidance on the use of CO2 has been added to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 2006 Handbook, Refrigeration.
The Handbook covers the refrigeration equipment and systems for applications other than human comfort. It includes information on cooling, freezing, and storing food; industrial applications of refrigeration; and low-temperature refrigeration. Primarily a reference for the practicing engineer, the volume is also useful for anyone involved in cooling and storage of food products.
