Correspondingly, why is ammonia a good refrigerant?
Ammonia, frequently used commercially in large freezing and refrigeration plants is also called “anhydrous ammonia” because it contains almost no water (it is 99.98% pure). Ammonia is a 3-10% more efficient refrigerant than CFCs, so an ammonia-based system requires less electricity, resulting in lower operating costs.
Also, how is ammonia used to make ice? Ammonia can easily be compressed in the form of liquid. On vaporization of liquid ammonia it absorbs large quantity of heat without changing its temperature. This is the reason why ammonia is used for making ice in the factories as it acts as a refrigerant.
Regarding this, how does a 2 stage ammonia refrigeration system work?
Two stage ammonia industrial refrigeration system The main flow of refrigerant passes through a coil inside the tank, the refrigerant passes through this and into the main expansion valve just like the single stage system then continues its flow via the separator, the evaporator and back to the separator.
How dangerous is ammonia refrigerant?
Ammonia refrigeration is very dangerous because when the chemical is mixed with air in the 16%-25% range it can cause a large explosion capable of leveling an entire building. The ammonia itself is also very toxic and is corrosive to the eyes, skin, and lungs.
