How Is Fluorine Used to Make Air Conditioners?

Fluorine is a toxic and corrosive gas but certain fluorocarbons were used in air conditioning and refrigeration but have been phased out because they damaged the ozone layer. In the present time, the refrigerant used in the air conditioners were known as CFC (Chlorofluorocarbon) and HCFCs (hydrochlorofluorocarbons). Both of these contains the element of Fluorine. But nowadays in HVAC industry R32 refrigerant is used which cause lower global warming potential.

1. can someone help me with problems im having with my air conditioner?

The problem is definitely not freon. Air conditioners do not leak freon - - the freon is inside a closed loop air-tight compartment. When air conditioners get old, the air compressor (a motor) gets weaker, and the unit will produce less cool air. This does not sound like your problem because your unit is relatively new. I would suspect that your A/C's filter might be clogged. If your unit has an electrostatic air filter then a clog would also explain the crackling noise you are hearing. The crackling noise is caused by strands of dust shorting out the air dielectric between the oppositely charged plates of your electrostatic air filter. If you still have the instructions that came with the unit, they will tell you how to clean out your air filter. This should fix all of the problems that you are experiencing. If you have any other questions, please feel free to E-mail me.

2. Why do 14,000 BTU air conditioners range so widely in recommended coverage. 350 to 700 Sq ft? Trying to cool approximately 700 Sq ft.

This will work. Just keep the coils of the unit clean and the filter cleaned or replaced as needed for good airflow. Seal all air gaps as best you can, to keep all that precious cooled air inside the space. An open door is the 'enemy.'On very hot afternoons, the temperaure might not come down as low as you would like. Considering the alternative, that slightly warmer air is mighty inviting. Consider buying a standing fan for use on those days

3. Do air-conditioners need a 3 minute break after being started or stopped?

Yes the 3 min let's the system pressure equalize If any less the compressor as a hard start an will Not Start all the time, causing damage

4. Why do air conditioners inside vehicles cause some people to vomit?

Truth be told, i'am hearing this for the first time!! thank you for passing on this information. Wow!...well...i think if that is the case then either the ac machine has some kind of malfunction going on and it probably causes certain people to react to it differently or probably the smell of freshener which is sitting on the air vents causes some people to vomit because many people cannot take the car freshener. Either its too minty or too sweet...probably thats why?I just searched this for you, this is a article written in the us of a, i hope it helps you with your understanding of why vomit does happen to certain people. n The device that makes driving bearable during hot weather can also be a breeding ground for fungi.nCondensation in a vehicle's air conditioner makes it a home for nasty spores that feed on insect parts trapped inside.nBefore long, the vents are spewing fungi and a "dirty-sock odor" along with cool air. n"The first thing people get are the classic allergy symptoms. Your eyes get itchy, your nose starts running and you start to sneeze," said Robert Simmons, a microbiologist at Georgia State University who has studied the problem.nThe fungus contamination is worst in the sticky Southeast, although no one knows what proportion of vehicles is affected. Simmons unveiled his findings this week to 12,000 researchers at the American Society for Microbiology Conference in Miami Beach.nHis team dismantled the air-conditioning units of 32 cars, from luxury to economy classes, and all were infested.nThe researchers found more than a dozen fungi, with such names as cladosporium, aspergillus and penicillium. nMost are mere nuisances, but a few can occasionally trigger serious reactions.nSome give off toxic byproducts.n"If you are allergic or sensitive to these fungi, it does not take very much to irritate you," Simmons said. "If you are not sensitive, it wo not matter at all. "nNo surprise to Richard Disney, general manager of Arctic Auto Air Conditioning near Fort Lauderdale. He said about one in 100 of his customers comes in complaining of AC allergies or stench.n"I get some asthmatic children, and people saying they can not breathe in their own car," Disney said. nAs more people become aware of fungus infestation, "I think it's going to be a problem we hear more of in the future."nIf the car appears to be stricken, there are options.nMost AC shops can clean the parts and spray them with an anti-fungal coating for $50 to $100. It may not kill the fungi for good. nA few automakers offer factory-installed filters that can be cleaned at home or at the shop. Separate filter units can be installed in some cars for about $500.nYou can try to stop the fungus before it starts growing. Upon reaching your destination, turn off the AC but keep the blower running for a few minutes. Simmons said that will help keep the system dry and unfriendly to fungus.nAutomakers could help by redesigning the units, he said. The moisture that sustains fungi comes mainly from condensation on the "evaporator," or cooling chamber, and gets spread by the blower motor, he said. Both are encased in plastic near foam, which traps the moisture.n"A lot of engineers do not think about the biological end," Simmons said.
