The history of ammonia refrigeration dates back to the mid-19th century when ammonia was first recognized as an effective refrigerant. In 1876, Carl von Linde, a German engineer, developed the first practical ammonia compression refrigeration system, revolutionizing the food and beverage industries. This invention enabled the large-scale preservation and transportation of perishable goods, transforming global trade. Over the years, ammonia refrigeration technology has undergone significant advancements, including improvements in compressor design, heat exchanger efficiency, and control systems. Despite the emergence of alternative refrigerants, ammonia remains a popular choice in industrial applications due to its excellent thermodynamic properties and environmental friendliness (zero ozone depletion potential and low global warming potential). In India, the adoption of ammonia refrigeration systems has grown steadily with the expansion of the food processing, cold storage, and pharmaceutical industries. Today, ongoing research and development efforts focus on enhancing the safety, efficiency, and sustainability of ammonia refrigeration technology. Modern systems incorporate advanced monitoring and control features, as well as improved safety measures to minimize the risk of ammonia leaks and accidents.

• Key Milestones:

  • 1876: Carl von Linde develops the first practical ammonia compression refrigeration system.
  • 20th Century: Continuous improvements in system design and efficiency.
  • Present: Focus on safety, sustainability, and advanced control systems.

• Impact:
