Liquid nitrogen is used in myriad diverse applications, including flash freezing seafood, creating "fogging effects" for the Las Vegas entertainment circuit, cold shock testing parts destined for the space shuttle and preserving biological samples. For most high-use facilities with cryogenic cooling operations, a bulk tank of liquid nitrogen provides a readily available source. But what is the best way to distribute the liquid nitrogen throughout the system?
In some ways, liquid nitrogen is perplexing. It looks like water, and one might mistakenly assume that its fluid transfer properties mimic those of water. But too many missteps in the early system design phase ...
