AMMONIA is suitable for the following applications:

• Food processing, Cold storage & Delivery: Ammonia refrigeration is the backbone of the food industry for freezing and storage of both frozen and unfrozen foods in many parts of the world (including fruits, vegetables, meat, poultry, fish, dairy, ice cream, beverages). In the range 50 kW to 200 kW ammonia may be used, and for larger freezers ammonia is almost always preferred due to improved energy efficiency and reduced leakage.
• Petrochemical & Pharmaceutical industry, Mining: For many years, ammonia has been the refrigerant of choice in large industrial refrigeration applications, including process cooling, cold storage, the production of ice for use in chemical reactions, and mining. Ice plants are typically far larger than those found in the food industry.
• Air Conditioning: Ammonia is increasingly used for air conditioning in public buildings, hospitals, colleges and office parks, as well as to enhance the efficiency of power generation facilities. Ammonia refrigeration has also been used to provide air conditioning for the INTERNATIONAL Space Station and the theme park Biosphere II, in the USA. 
• Chillers: Chillers using R717 and a secondary heat transfer fluid (intrinsic to chillers) are available in the capacity range from 200 to 2000 kW with a few larger models. They allow for the safe use of ammonia in large buildings. Ammonia can be used in absorption chillers – with water as the absorbent –, in screw chillers, or in reciprocating chillers. The new Terminal 5 of Heathrow, one of the world’s largest airports, is using a central ammonia chilling plant to provide all heating and cooling. 
• Supermarkets: More recently, ammonia has been used in conjunction with a secondary refrigerant such as carbon dioxide in a ‘cascade’ system, MEANING that less ammonia is required to achieve satisfactory results, and that the ammonia charge can be contained in a plant room or other safe environment. 
• Marine refrigeration / Fishing vessels: R717 has been increasingly used in marine refrigeration equipment. Applications include its use for reefer ships, as proposed refrigerant for sorption ice machines, and for fishing vessels both as single refrigerant as well as in combination with CO2 (R744), especially for low temperature uses.
• Heat pumps: Absorption heat pumps for hot water space heating are mostly gas-fired and commonly provide cooling simultaneously with heating. An updated family of absorption machines is available using an ammonia-water cycle powered by natural gas. R717 has also been used in medium-size and large capacity heat pumps. In addition, progress has been made in the field of using ammonia for residential heat pumps, with initial prototypes with an output of 6 kW having reportedly worked reliably with ammonia charges of less than 100g.
• Leisure industry, Ice Rinks, Ski Slopes: Ammonia can be used for refrigeration purposes in ice rinks and ski Slopes, and in parallel, for the heating of leisure facility premises.. Europe’s largest open air stadium with an ice rink (Karlstad, Sweden), and the world’s third largest indoor snow park (Dubai, EMIRATES) are both using R717 to CONSTANTLY produce ice and snow.
