Ammonia

Ammonia (NH3) is most often used in large industrial enterprises. Freezers for packing houses, as a rule, use ammonia as a refrigerant. The gas with very noticeable smell. Even a small leak can be detected with the nose. Its boiling point at atmospheric pressure -28 degrees Fahrenheit (-33 degrees C). Its freezing point-107.86 degrees Fahrenheit (-77.7 degrees C). It is very soluble in water. Greater cooling possible with a few machines. She has a high latent heat (555 BTU in 18 degrees Fahrenheit (-7.7 degrees C). It can be used with steel reinforcement. Water cooled typically used for cooling refrigerant. High pressure in the line (from 125 to 200 pounds per square inch). Anyone inside the cooling unit, if it proceed quickly overcome by evaporation. Fresh air, you want to reduce the toxic effects of ammonia Dymov. Ammonia is flammable in conjunction with certain volumes of air (about one volume of ammonia in the two volumes of air). This is even more fuel is combined with oxygen. It is highly toxic. Heavy steel armature is required because of the pressure of 125 to 200 pounds per square inch are common. Blocks should be water-cooled.
