A course focusing on industrial refrigeration as practiced in food freezing and in other low temperature applications will be presented in a virtual format due to COVID-19. Hosted by the International Institute of Ammonia Refrigeration, the 54th industrial refrigeration workshop will be held virtually on March 8-18.

Sessions will be conducted live, and participants will interact in real time with the instructors and other students. A simulation of the process to design an ammonia refrigeration system serving a food distribution center and incorporating selected low charge technology will provide an ongoing theme that will be use to demonstrate key principles throughout the course.

Topics to be covered include refrigerant properties; single-stage, two-stage and cascade refrigeration cycles; load calculations; the construction of refrigerated buildings; liquid recirculation systems; reciprocating and screw compressors; performance and selection of evaporator coils; condensers; energy conservation; vessel sizing; liquid pumps; pipe sizing; safety; and control of both halocarbon and ammonia systems.
