IIAR and the Natural Refrigerant Foundation held their board meetings in Dallas in October. Gary Schrift, president of IIAR, said the meetings were well attended. During the sessions, committee chairs provided updates on the critical work they are doing.
Read MoreSimple Equations for Determining Mass Flow in Refrigeration Systems
The goal of any industrial refrigeration system is to remove heat. Therefore, the total heat load is the design engineer’s first calculation, which is then used to size and select the evaporators. Unfortunately, this heat load is often also applied to the sizing of other components in the system, which can result in errors.
Read MoreTHE TECHNICIAN SHORTAGE
The refrigeration industry has been facing a shortage of skilled workers for years, and the problem continues to grow, creating significant challenges, disrupting essential operations, and limiting growth. “At a high level, the workforce shortage creates a bottleneck that threatens the industry’s ability to meet regulatory timelines,” said Danielle Wright, executive director of the North American Sustainable Refrigeration Council.

Understanding
Have you ever thought about your understanding of the equipment and tools we use as well as the entire refrigeration system(s)? Many times, or maybe all of the time we assume we or someone else understands until something happens. This may be like the definition of confidence I have heard, which is “That feeling you get just before you understand the situation.”
