COOOL R717 is a natural refrigerant gas, with multiple applications in industrial refrigeration, especially in R744 cascade systems or in secondary fluid systems, such as glycol water. Its main characteristics are: High refrigerating power. GWP – Global Warming Potential = 0.
What is the chemical formula of R 717?
Ammonia Gas or Refrigerant R717 Ammonia refrigerant is commonly known as R717 and its chemical formula is NH3. Its molecular weight is 17 and boiling point is -28 degree F (-2.22 degree C).
Is R717 flammable?
Ammonia suitable for use as a refrigerant is commonly named R717 in the refrigeration and air conditioning industry. R717 has some different chemical properties than fluorocarbon refrigerants, being flammable, toxic and corrosive. Therefore the handling and use of R717 requires adequate safety measures.
What are the concerns if R717 is used as the refrigerant?
Danger to life in case of refrigerant leakage! Ammonia (R717) is toxic and, when present in high concentration, causes burns to the skin, mucous membranes and eyes and leads to paralysis and suffocation! In liquid form, it can cause frostbite on contact with the skin!
What is R717 used for?
R717 (Ammonia) is refrigerant grade Ammonia (NH3) used in low and medium temperature refrigeration. It is a colourless, pungent, highly toxic gas but is a very efficient refrigerant with zero Global Warming Potential (GWP).
How is refrigerant leak detected?
If the air consists of refrigerant (due to leakage) then it is detected by the change in the colour of the flame. Thus the leak detector consists of a sampling tube through which air around the refrigeration system is drawn by means of a small fan. The air sample is passed over a heated platinum element.
Does R717 deplete the ozone layer?
Refrigerants such as Ammonia (R717), Carbon Dioxide and non-halogenated hydrocarbons do not deplete the ozone layer and have no (ammonia) or only a low (carbon dioxide, hydrocarbons) global warming potential.
Which refrigerant is widely used in domestic refrigerator?
The refrigerant commonly used for domestic refrigerators is ammonia. 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).
What is ammonia refrigerant (R-717)?
Ammonia, also known as R-717, is one of the oldest refrigerants. It’s origins as a refrigerant can be traced all the way back to the 1800’s and it was one of the first refrigerants used in a variety of applications. It is also widely considered one of the most efficient refrigerants available.
What is R717 refrigerant used for?
R717 (Ammonia) is refrigerant grade Ammonia (NH3) used in low and medium temperature refrigeration. It is a colourless, pungent, highly toxic gas but is a very efficient refrigerant with zero Global Warming Potential (GWP).
What is R-717 and where is it used?
In today’s world R-717 has made an amazing comeback. It can be found in varying ranges of applications. Because it is so efficient it is often used in very large applications such as meat packing/processing plants, refrigerated warehousing, and even ice rinks.
Is R-717 natural refrigerant making a comeback?
It wasn’t until the 1980’s and 1990’s, when these artificial refrigerants began to be phased out, that we saw natural refrigerants began to rise again. In today’s world R-717 has made an amazing comeback. It can be found in varying ranges of applications.
