  • TC 3.2 Refrigerant System Chemistry

    Technical Committee 3.2 is concerned with all chemical reactions occurring inside refrigerant systems and with effects of temperature, pressure and materials on the reaction rates. Materials of primary interest include refrigerants, lubricants, lubricant additives, motor insulation, driers, and metallic structural materials.

  • TC 3.3 Refrigerant Contaminant Control

    Technical Committee 3.3 is concerned with sources, generation, and control of water and other contaminants in refrigerating systems. It is also concerned with recovering, recycling, and reclaiming refrigerants with in-system cleanup methods. Identifying and quantifying contaminants are of particular interest. Properties and performances of filters and driers are within the scope of responsibility.

  • TC 3.8 Refrigerant Containment

    Technical Committee 3.8 is concerned with methods of construction and service practices to maintain tight refrigeration systems and for storing and handling refrigerants in external containers. It is also concerned with leak detection, evacuation, and minimizing refrigerant emissions while servicing refrigerating systems.
