Title: Ammonia


1
Ammonia Good for Business Great for the
Environment
  • Bruce Badger, President
  • International Institute of
  • Ammonia Refrigeration

2
The Business Decision
  • The refrigeration system is a utility service for
    cold stores, food processors and other industrial
    users. It is not the primary focus of their
    business.
  • Mandate lower the cost of operation.
  • Most efficient refrigerant ammonia
  • Lowest cost refrigerant ammonia
  • Lowest leak rate ammonia

3
The Environmental Decision
  • Reduce environmental impact of business
    operations
  • Select the lowest Global Warming Potential
    refrigerant ammonia
  • Select the lowest Ozone Depleting refrigerant
    ammonia

4
Other Considerations (costs)
  • Regulatory Compliance meeting the obligations
    for refrigeration system design, operator
    training, operator certification, refrigerant
    charge limitations, reports, registrations
    (filings)
  • Sustainability investment in refrigeration that
    will continue to be efficient and compliant with
    regulations for the life of the facility

5
Case Study
  • A 150,000 sq. ft. (13935 m2)
  • Central ammonia system VS multiple split
    halocarbon R-507 system.
  • The distribution center was assumed to be new
    construction

6
Case Study Considerations
  • Initial Construction
  • Energy and Operating Costs
  • Maintenance costs
  • Major Component Replacement Costs

7
Simple Payback
  • Initial cost difference
  • 2,100,000 1,892,000 208,000
  • Operational Cost Difference
  • 453,663 329,825 123,838
  • Simple Pay-Back
  • 208,000 first cost difference
  • 123,838 annual savings 1.68 years

8
20 Year Life Cycle Comparison
  • Initial Construction Cost Difference
  • 2,100,000 (Ammonia) 1,892,000 (Halocarbon)
    208,000
  • Total 20 Year Operational Cost Difference
  • 11,282,147 (Ammonia) 16,161,757
    (Halocarbon) 4,880,610
  • Investing an extra 208,000 in construction costs
    results in a 4.88 Million savings over 20 years.

9
Sustainable Benefits
  • Self-alarming odor helps to detect leaks and
    minimize emissions.
  • Low replacement cost
  • Requires less primary energy to produce a given
    refrigeration effect than other common
    refrigerants (highest coefficient of performance)
  • Naturally occurring green substance
  • No potential for ozone depletion (Ozone Depletion
    Potential 0)
  • No potential for direct global warming impact
    (Global Warming Potential 0)
