This paper seeks to explain the reasons why ammonia has been so widely used as a refrigerant for so long, without using buzzwords, jargon or technical terms. The purpose is to provide engineers and technicians with information which may usefully be passed on to managers, financial controllers ...
While there are other uses of ammonia, most (about 80%) of the industrially manufactured ammonia is used for fertilization purposes. Other uses of ammonia include its applications as a refrigerant and water purifying agent. Ammonia is also an important component while making explosives, other chemic...
Determine the values of the specified properties at each of the following conditions. a. For Refrigerant 134a at T = 60C and v = 0.072 m ^3/kg, determine p in kPa and h in kJ/kg. b. For ammonia at p = Explore our ...
Another option is to use mixtures of hydrocarbons such as butane. Hydrocarbons pose safety risks as they arehighly flammableand may also adversely affect air quality. Ammonia is another alternative that has been used as a refrigerant for a long time but ishighly toxic. And, finally, there is ...
Based on the Protocol of Montreal and later the Kyoto Protocol, increasingly sharper legislation onrnsynthetic refrigerants made that alternatives have been developed and that techniques from almost arncentury old are reviving.rnOn the other hand, the natural refrigerant ammonia is also subject to ...
