What is Ammonia Refrigeration?
The mechanical process of ammonia refrigeration changes a liquid into a gas which causes it to absorb heat in the process. The heat is then transferred - usually to an outside heat exchanger or cooling tower.
Ammonia refrigeration is very common and used extensively - particularly in industrial applications such as food processing, (meat packing/processing, produce, seafood and poultry) refineries and petrochemical plants as well as in the pharmaceutical industry and breweries, for chilling beer!
Ammonia is once again becoming a very popular refrigerant for a number of reasons:
¡¤ ammonia has superior thermodynamic qualities, as result ammonia refrigeration systems use less electricity.
¡¤ Ammonia refrigeration is not harmful like most every other refrigerant such as CFCs.
¡¤ Ammonia does not deplete or harm the planet's ozone layer.
¡¤ Ammonia, as a refrigerant is also readily available and inexpensive - especially when compared with other refrigerants.
¡¤ Under part-load conditions, the ammonia-based reciprocating compressor maintains its efficiency and the screw compressor becomes less efficient resulting in higher operating costs.
