On what principle fridge works and how it creates cfcs which pollutes weather?

Question

Actually I know that functioning of fredge creates chloro floro carbons and which pollutes the whether.But I want actully process goingon in the fredge functioning.

Answer 1

Refrigerators and air conditioners do not create CFCs. They are filled with CFCs, like Freon, when they are manufactured or installed and those CFCs stay inside unless there is a leak. If it leaks out, the unit will no longer cool, so a repair technician much add more, But the lost CFC is now in the air. So if we could just make 100% leak proof refrigerators and always reclaim used CFCs from old units, there would be no air pollution problem. New laws in the US require all refrigerator and air conditioner technicians to prevent CFCs from leaking. In the past, they would just let the CFCs out into the air whenever is was convenient while they were working on the unit, but now they have to pump it out into a storage tank. And all new units are made to use a different chemical that is less harmful, so that it it does accidentally leak out it does less damage.

By the way, early refrigerators used ammonia instead of CFCs, but there were a number of cases of people being killed when their refrigerator leaked, so Freon, a non-toxic chemical, was invented to replace ammonia in refrigerators. Some industrial chillers still use ammonia, but they are all outside units with cold salt water being pumped from the chiller to the building for cooling. That way any ammonia leak is outside the building.

Also, CFCs used to be used in spray cans and other places where they were intended to be released. That is illegal now.

Answer 2

The fridge doesn't produce any cfc's, but the gaz/fluid used in the system contains cfc's. So if the fridges working life is expired, the waste coming from it has cfc's in it and has to be processed accordingly.

Answer 3

only pollutes if leaks, the freon is condensed, then passes through coils in which warmer air is forced through, the liquid freon absorbs the heat from the air through the metal fins and coils, this causes the freon to evaporate, and when it evaporates it absorbs heat, thus cooling the air passing through the metal fins and coils on the inside, then the gaseous freon goes through a compressor and the heat is expelled outside through the metal fins and coils on the outside in which the outside air is cooler than the heat from the compressed freon going back into liquid form, and fan on outside blows that hot air outside, did you ever hear of the saying a picture is worth a 1,000 words, well i'm getting tired of typing, you need to find a diagram somewhere in a textbook on air-conditioning and refrigeration or search the Internet, whoops typing cramp!

Answer 4

refrigerators do not use cfc's anymore they use safer refrigerants now such as hcfc's and isopropane

Answer 5

no
