CO2 Is Viable

Carbon Dioxide refrigeration and cooling - CO2. Unfortunately, the vast majority of owners and operators are not informed about the commercial viability of this high performing solution.

CO2 is successfully deployed in large supermarkets, distribution centers, cold storage facilities, food and beverage production, data centers and recreational facilities. For those very large applications, CO2 and ammonia hybrid systems offer outstanding performance qualities and lower initial and operating costs, while also reducing health, safety and environmental risks - there is up to a 90% reduction in your ammonia charge.

Check with your insurance providers to see what cost reduction in risk mitigation would be forthcoming by either eliminating or reducing your ammonia charge.

Unfortunately, manufacturers continue to not fully inform their clients about the high Global Warming Potential (GWP) of the refrigerants they use. Refrigerants such as 134a, 410 and others are already being legislated for reduction and restriction in Europe past 2022. In most instances, the Americas will follows suit.

If you are contemplating an investment in new systems then make sure you are fully informed, as the equipment you buy in next few years will be in operation past 2030. Neelands is one of the first companies in Canada to provide design/build and service for CO2 systems.

Don't hesitate to contact us to receive a lunch and attend a CO2 seminar for your production and health and safety team.

New Rules Coming

The critical issue of managing refrigerants now includes steps being taken in Europe and the Americas to restrict and eliminate HFCs, as these synthetics have a high Global Warming Potential (GWP). Specific target markets include supermarkets, motor vehicles, mold injection and aerosols.

The Ontario government will soon move forward with a cap-and-trade system and carbon-pricing methodology. There will be an overall emissions cap on those facilities that are included in the program, plus ways of rewarding companies that produce less emissions than the limits.

With a life expectancy of mechanical store assets of at least 15 years, an owner now in the planning and development phase will be building a facility designed to operate efficiently into and beyond the year 2029.

As the expected new HFC legislation will be applied by 2022, any new commercial refrigeration system being contemplated should include a comprehensive review of CO2.

CO2 is non-toxic, non-flammable, has a high-refrigeration volumetric capacity, a high-convective heat transfer coefficient, low critical points, an ODP (ozone depletion potential) of 0, and a GWP of 1.

Neelands embraces and leads in its commitment to protect the environment - and we facilitate informed decision-making for our customers.

The Basics

After decades of successful and well-proven operation, HFCs and ammonia as refrigerants are now declining in usage due to their environmentally harmful qualities, as well as health and safety issues.

Although possessing outstanding thermodynamic properties, plant owners and corporate board members are starting to turn to other refrigerant solutions, including CO2.

Switching to CO2 has the advantage of delivering many benefits to operators. These include avoiding the costs of a future HFC retrofit, reduced health and safety issues, plus savings on refrigerant costs, on maintenance and on energy performance.

For instance, ammonia R-22 and R-717 are widely used as primary refrigerants to cool a secondary fluid, traditionally brine. But now CO2 can be used as the primary and secondary fluid, consequently eliminating the need for a heat exchanger and improving the overall efficiency of the refrigeration cycle. Alternatively, CO2 can also be used only as a primary fluid combined with a conventional secondary fluid. These factors all point to improved efficiencies and lower maintenance costs for operators.
