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.It’s going to be a hot week for many Americans. 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. ac unit not reaching set temperatureThe evaporator helps cool the air, the condenser readies the refrigerant for the cooling process, and the compressor moves refrigerant back and forth between them. tax credit for ac unitsThe evaporator and the condenser are both made out of copper coils, and there is some copper in the compressor, too. why is my ac unit always running

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.

Mechanical engineers aren't particularly interested in making lighterunits. Instead, they're focusing on developing more ecological air-conditioning systems. 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.
