Don Cole, a refrigeration expert, highlights how the integration of a CO₂ system made for a flawless start-up in a Zero Zone installation, showcasing the smooth commissioning process and seamless operation in a new retail store.

CO₂ refrigeration, which has gained significant traction in ice arenas and supermarket coolers, is now emerging as a groundbreaking technology revolutionizing the way we cool and heat across industries worldwide.

CO₂ refrigeration (R-744) was selected to cool four ice rinks at the Winter Olympics, curbing carbon emissions to the tune of 1.2 million planted trees.

The data paints a promising future; however, the question remains: who’s going to install and maintain all of these R-744 systems?

Compiled via interviews with a team of experts, here are the steps one should follow when charging a CO₂ refrigeration system.

While CO₂ refrigerant may not be as deadly to the environment as its HFC peers, there are other concerns that exist when it escapes a system.

As the industry continues to evolve, it’s essential for HVACR contractors to embrace comprehensive training programs that address both foundational knowledge and hands-on experience with CO₂ systems.

As Americans embrace a more sustainable future, the refrigeration equipment and architecture must continue to evolve

The escalating demand for sustainable, energy-efficient, and environmentally conscious cooling technologies presents a compelling business case for CO₂ refrigeration. And U.S. businesses are taking notice.

Chillventa 2024, held Oct. 13-15 in Nuremberg, Germany, showcased some of the world’s most innovative technologies to more than 33,000 attendees from 49 countries. Through more than 250 presentations, visitors were privy to the latest developments driving innovation throughout the HVAC industry.

The commercial and industrial refrigeration sector is going green. This evolution is largely dictated by corporate environmental, social, and governance efforts; the demand for greater energy efficiency; government regulations; net-zero energy goals; and more.

CO₂ systems’ environmental benefits and ability to meet any future regulations make them an optimal option for contractors and facility managers.
