The cyclical pattern of change in refrigerants is linked directly to our growing understanding of the unintended consequences of refrigerant interactions with our atmosphere, coupled with advancements in technology and shifts in societal values toward sustainability. One only needs to look at the evolution of refrigerants to see these trends at play.

Smartcool Systems Inc. and Tri-Caribbean Energy (TCE) announced that the Smartcool ECO3, as a part of TCE’s Green Energy Management (GEM) Power Savings Bundle, is reducing energy consumption by 31 percent on refrigeration systems at the Crystal Cove Hotel in Barbados.

A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to troubleshooting a system.

Refrigeration contractors are keenly aware of the value of the maintenance they perform for their grocery store and supermarket clients, but, in some cases, they may find themselves working with clients who underestimate it.

Wiegmann Associates announced it has completed work on a new LEED-certified refrigerated food distribution center for The Chefs’ Warehouse in Las Vegas. As engineer of record and mechanical and controls construction manager, Wiegmann designed and installed all refrigeration systems, HVAC equipment, and a building automation system.

The world is changing and the refrigeration industry is changing along with it, but the refrigeration field is strong and will continue to be a great industry to work in for the next generation.

Danfoss recently hosted its 25^th EnVisioneering Symposium, which addressed how an increasing industry-wide focus on refrigerants and energy is driving changes in the design, deployment, and maintenance of refrigeration equipment and supermarkets.

Emerson Climate Technologies Inc. addressed issues like the delisting of specific gases in certain applications and energy consumption reduction regulations at its E360 event held Sept. 3 at the Westin Dallas Fort Worth Airport Hotel in Dallas.

Last month’s article covered a 400-series refrigerant blend’s total temperature glide, effective temperature glide, fractionation, superheat, subcooling, and average evaporator and condensing temperatures using a pressure/temperature chart. This article deals with system pressure drops and net temperature glide in a refrigeration and/or air conditioning system.
