Since CFC is hazardous to our atmosphere, are there any better substitute to replaced CFC in fridge, air conditioner etc.?
SwAnK said:I always though you could use water because of its high heat capacity. Nuclear power plants do this, except in this case, for a fridge, an antifreeze would prbably half to be added. And some way of cycling the water, through something that could cool it off quickly, so it could gather more heat again.
Astronuc said:Using water (without antifreeze) would require a Tcold greater than 0°C (32°F).
Offhand, I don't believe that it would be practical (but I could be wrong). What pressure level would one consider?Clausius2 said:Would it not be possible (practical) to design a pressurized water circuit to avoid its freezing?. I mean, if you work with a pressure little above of the atmospheric one, the evaporator could reach less temperature than 0ºC.
The primary purpose of finding an alternative to CFC (chlorofluorocarbon) is to protect the Earth's ozone layer. CFCs have been found to contribute to the depletion of the ozone layer, which protects us from harmful UV radiation.
There are several alternatives to CFC that have been developed, including HFCs (hydrofluorocarbons), HCFCs (hydrochlorofluorocarbons), and natural refrigerants such as ammonia and carbon dioxide.
While these alternatives do not contribute to ozone depletion, they may still have negative impacts on the environment. For example, HFCs are potent greenhouse gases and contribute to climate change. It is important to carefully consider the environmental impact of any alternative to CFC.
Some alternatives to CFC may have safety concerns, such as flammability or toxicity. It is important to carefully handle and use these alternatives according to safety guidelines to prevent any accidents or harm to individuals or the environment.
While it is possible to replace CFC with alternatives, it may not be feasible in all industries or countries. Some alternatives may be more expensive or may require significant changes in equipment and infrastructure. It is important to carefully evaluate the feasibility and impact of replacing CFC with alternatives on a case-by-case basis.
