Industrial Refrigeration Basics - The Engineering Mindset

2019-02-07· We start off with the compressor, this is the heart of system and is what pumps the ammonia refrigerant around the refrigeration system to provide the cooling. It pulls in refrigerant that has collected all the unwanted heat from the evaporator and it compresses this into a much smaller volume so all that thermal energy is very tightly packed together, making the refrigerant very hot. The ...

A Look at Ammonia Refrigeration Through the Years

2001-04-26· If you can picture the compression refrigeration cycle, the only thing that moves the refrigerant is the compressor. Ammonia, which requires the movement of less than one-half pound per minute, is the most efficient refrigerant. Any other refrigerant will require the movement of slightly over two-and-one-half pounds per minute per ton of refrigeration. Ammonia has been, and always will be, …
