Simple 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.

THE 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.”

The Design of CO2 Refrigeration System Using Ammonia System Design Principles

Over the past 20 years or so the use of CO2 refrigerant as the first stage of CO2/HFC and CO2/NH3 cascade systems has increased significantly. The use of two-stage transcritical CO2 systems, which are invariably air cooled, is an increasing trend. Frequently, two-stage gas coolers are used with water sprayed on the secondstage air-cooled gas coolers to reduce the gas cooler exit temperature to as low a value as possible.
