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.
