Development of Mechanical Refrigeration
The development of mechanical refrigeration dates back to the early days of the industrial revolution. Today, ammonia remains the most commonly used refrigerant in large industrial systems to process and preserve most food and beverages. Ammonia has been in the forefront of advances in refrigeration technology making it is essential to the food processing, storage and delivery infrastructure of our economy. More recently, ammonia refrigeration systems have been used for air conditioning in publically accessed buildings and increasing output efficiencies for power generation facilities. NASA also recognizes the advantages of ammonia as a refrigerant, selecting ammonia for use on the Space Station.
With heighted attention given to global warming and the extraordinary international efforts made over the past decade to reduce the use of refrigerants harmful to the environment, combined with its economic advantages, ammonia is well positioned to be the refrigerant of the future.
