IIAR Committees



Developed and maintains the IIAR CO2 handbook, which guides refrigeration practitioners on the theory, design, and practical application of refrigeration and heat pump systems that use carbon dioxide (CO2) as the refrigerant. The handbook addresses subcritical CO2 application, transcritical CO2 applications, and CO2/ammonia cascade system designs.  The CO2 handbook committee may also develop research proposals and educational program proposals related to the use and application of CO2 refrigeration and heat pump systems.
