If you’ve ever installed a window air-conditioning unit in your old apartment, you know that your AC is inexplicably heavy for the small space that it cools. It takes a lot of copper to produce all that cold air, Kelly explains. Her original piece, from 2011, is reprinted below. With temperatures rising, Americans have begun the annual summer tradition of installing cumbersome removable air conditioners. It's tough to find a window unit that's lighter than 46 pounds—and a machine like that would be able to cool only a fairly small room (150 square feet or less).
What makes them so heavy?Air-conditioning systems—both centralized ones and window units—have three important components: an evaporator, a condenser, and a compressor. The evaporator helps cool the air, the condenser readies the refrigerant for the cooling process, and the compressor moves refrigerant back and forth between them. The evaporator and the condenser are both made out of copper coils, and there is some copper in the compressor, too. Copper is pretty heavy, weighing some 558 pounds per cubic foot, and the copper components account for as much as 60 percent of the weight in smaller units—though the percentage declines as they get heavier. (Units can be as massive as 213 pounds, the weight of the heaviest window unit sold by the Friedrich Air Conditioning Co.) Steel, which provides structural support and houses or covers the compressor, accounts for the rest of the weight. Aluminum, which weighs about 169 pounds per cubic foot, could theoretically be substituted for copper.
But manufacturers continue to use copper because it's a better conductor of heat. (That's important because an air conditioner works by essentially removing heat from the air.) Furthermore, the cost of an air-conditioning unit would increase if manufacturers used aluminum because of the new equipment and employee training they would have to invest in to make the necessary parts. Additionally, so much more aluminum would have to be used—to ensure that passageways in the unit were thick enough to withstand the high-pressure refrigerant moving through them—that units might not be that much lighter.cheapest window air conditioner units Mechanical engineers aren't particularly interested in making lighterunits. how to make your own ac unitInstead, they're focusing on developing more ecological air-conditioning systems. how to remove a ac unit
One technique they're experimenting with is so-called "dew-point cooling," which relies on the natural energy produced by evaporating water, rather than fossil fuels. But it's not clear when greener units will be widely available—or if they'll be significantly lighter.

Has great cooling power. Noisy, small parts come loose and rattle against each other frequently. WORKS WELL AFTER 2 YEARSNot great, not terrible, just middle of the road. It's super loud, ignore any other statements on its noise because they are just not true. It definitely does the job but I have to take two full stars off because it is LOUD. I mean in order to watch tv we had to turn the volume up from 16 to 26. Has worked well since I bought is, so I can't complain. I love the temperature sensing remote. All in all, a great product. I just purchased this unit. I have a garage turned office space (20x15) that needed cooling. It would get way too hot during the Texas summer time heat to be in the office. This is an amazing window air conditioner. Love it, love it, love it!!!As you shove an air conditioner into your window to ward off the summer heat, you may wonder why such a small appliance is so incredibly heavy. If you thought it was some conspiracy to break your back and your window sill at the same time, you'd be wrong.
Air conditioning units are laden down with copper which weighs a whopping 558 pounds for each cubic feet of metal. This copper is hiding in the evaporator and the condenser coils which remove heat from the air and replace it with cool air. Even the compressor has smidgen of copper. Almost 60% of the weight of the cooling unit comes from these copper components.Despite its weight, copper is the #1 choice among manufacturers as it is abundant, relatively inexpensive and an excellent conductor of heat which makes it perfect to keep you cool as a cucumber on even the hottest of days. Giz Explains is where we break down whatever science or tech questions are scratching at the backs of our noggins. Got questions of your own? and we'll see about answering them.Chinese material scientists have created the world’s lightest material: A graphene aerogel that is seven times lighter than air, and 12% lighter than the previous record holder (aerographite). A cubic centimeter of the graphene aerogel weighs just 0.16 milligrams — or, if you’re having a problem conceptualizing that, a cubic meter weighs just 160 grams (5.6 ounces).
The graphene aerogel is so light that an cube inch of the stuff can be balanced on a blade of grass, the stamen of a flower, or the fluffy seed head of a dandelion (see pictures below). Most aerogels are produced using a sol-gel process, where a gel is dehydrated until only the aerogel remains. Some aerogels are also produced using the template  method — aerographite, for example, is created by growing carbon on a lattice (template) of zinc oxide crystals — and then the zinc oxide is removed in an oven, leaving just the carbon aerogel. To create the graphene aerogel, however, researchers at Zhejiang University use a novel freeze-drying method. Basically, it seems like the researchers  create a solution of graphene and carbon nanotubes, pour it into a mold, and then freeze dry it. Freeze drying dehydrates the solution, leaving single-atom-thick layers of graphene, supported by carbon nanotubes. The researchers say that there’s no limit to the size of the container: You could make a mini graphene aerogel using this process, or a meter-cubed aerogel if you wish.
The end result is an aerogel that weighs just 0.16 milligrams per cubic centimeter, and has truly superb elasticity and absorption. The graphene aerogel can recover completely after more than 90% compression, and absorb up to 900 times its own weight in oil, at a rate of 68.8 grams per second. With these two features combined, lead researcher Gao Chao hopes that the material might be used to mop up oil spills, squeezed to reclaim the oil, and then thrown back in the ocean to mop up more oil. Beyond filtration, graphene aerogel might be used as insulation — or, if it’s as conductive as aerographite (which seems likely), graphene aerogel could enable the creation of lighter, higher-energy-density batteries.Over the next few pages we’ve compiled some amazing photos of aerogels.
