Ammonia refrigeration

Because of its better heat transfer properties, ammonia requires a lower heat transfer area than most chemical refrigerants. Furthermore, ammonia also has a clear advantage due to its low environmental impact with ODP and GWP = 0.

Ammonia refrigerant in various refrigeration systems

Ammonia can be used as a refrigerant in various industrial and commercial refrigeration systems such as:

  • Cold storage
  • Food and beverage industry
  • Chemical & process plants
  • Ice rinks
  • Commercial refrigeration systems
  • Commercial and industrial heat pumps

Ammonia, R717 is an attractive refrigerant alternative offering wide application ranges from high to low temperatures and considerably lower cost (per kg) compared to HFC refrigerants.

Heat exchanger functions

Heat exchanger functions in ammonia systems can work as:

  • Evaporator
    • Direct expansion
    • Flooded
      • Thermosyphon
      • Pumped circulation
  • Condenser
  • Desuperheater
  • Economizer
  • Cascade
  • Compressor Oil cooler
    • Thermosyphon
    • MEG cooled
    • Water cooled
