Industrial Refrigeration: Ammonia and CO2 Systems

 

The turn of the new year signaled the most recent step of the R22 refrigerant phase-out in the United States.

As a reminder, here’s the timeline according to the EPA final rule:

  • On January 1, 2018, R22 production dropped 30 percent from the 2017 supply to 9 million pounds
  • On January 1, 2019, production will drop 55 percent from the 2018 supply to 4 million pounds
  • On January 1, 2020, R22 will be phased out completely with no new or imported R22 allowed in the U.S.

Since the supply just dropped at the beginning of this year, that means R22 prices (and repair prices) are increasing yet again.

If your refrigeration system uses R22, or any other refrigerant with a high Global Warming Potential (GWP), you have some decisions to make — and the clock is ticking.

Did you know that up to 60 percent of a manufacturing facility’s total operating expenses comes from industrial refrigeration? It’s no surprise that refrigeration efficiency is a priority.

However, engineers often look to optimize individual components rather than taking a holistic approach, leading to wasted energy and operational inefficiencies. To avoid this fragmented approach, here are six steps to optimize the entire system and achieve the greatest energy efficiency:

Stellar is gearing up for ATMOsphere America 2017, the leading forum for discussion about the business case for natural refrigerants in North America. The three-day conference next month will host more than 400 industry stakeholders in San Diego, California, and will feature discussions about the latest in refrigeration technology and regulation. Among the hot-button issues in the industry: the diminishing role of hydrochlorofluorocarbons (HCFCS).

Ammonia Refrigeration Compliance: How an Engineering Bid Package Can Provide Owners with a Comprehensive Compliance Solution

Compliance audits for ammonia refrigeration are increasingly more detailed with regulatory standards maturing every year. Which begs the question: How prepared or risk-prone do you want your facility to be?

Compliance is just one of several issues on the agenda this week for the regional conference hosted by the Central Florida Chapter of the Refrigerating Engineers & Technicians Association (RETA). In addition to refrigeration maintenance and operation, attendees at the Central Florida Ammonia Refrigeration Regional Conference will also focus on the importance of compliance with regulators like OSHA.

15 Common Ammonia Safety Issues Your Refrigeration Personnel Can Control (And Correct)

More changes are coming to the food and beverage industry as the U.S. Environmental Protection Agency (EPA) continues to crack down on ammonia safety.

The EPA has launched a three-year, nationwide enforcement and compliance initiative focused on reducing the risks of chemical releases from facilities that use extremely hazardous chemicals, including those that use ammonia as a refrigerant.

5 Types of Low-charge Refrigeration Systems

After months of discussions and hours of negotiations, nearly 200 nations have now reached a deal to limit the use of greenhouse gases worldwide. In October, world leaders agreed to the deal that would gradually phase out the use of hydrofluorocarbons (HFCs) starting in 2019.

There has been a push to take advantage of the benefits of ammonia while reducing the risks—and it has resulted in an innovative solution: low-charge packaged refrigeration systems that use ammonia and a secondary refrigerant (such as glycol). This allows facilities to reap the benefits of ammonia’s excellent thermodynamic properties while minimizing the charge and risk.

One of Florida’s oldest third-party logistics companies is introducing one of refrigeration’s newest innovations into its new cold storage facility: low-charge packaged refrigeration systems. With a focus on moving to eco-friendly refrigerants, McDonald’s franchisee Caspers Cold Storage and Distribution will be cooling its new warehouse with an ammonia/ CO2 and low-charge ammonia DX system. Because Stellar will be designing and building the new systems, Accelerate America editor Andrew Williams interviewed Stellar’s Brandon France to learn more about the project. Check out the feature article, “I’ll have CO2 and ammonia with that” in this week’s blog post to learn more about how the company is using low-charge refrigeration systems to lower costs, reduce installation time and utilize green refrigerants.

Can Compressed Air Systems be a Source of Contamination?

Did you know that compressed air systems can be a source of contamination in your food plant? Dangerous bacteria and pathogens can be difficult to spot in your facility—especially if they are airborne. It’s a common misperception that compressed air is considered as clean as the air from the outdoor environment that surrounds your facility—NOT true. Once in the compressor, the air outside of your facility (ambient air) mixes with other elements within your compressor (i.e., corrosion, worn seals). Whatever is not caught in your filtration system is then circulated throughout your plant.
