Do not give your old metal refrigerator for a pittance. If you remove the compressor from it (or, as many still call it - the engine), you can slightly increase the cost of the old unit. So how much copper can be in the refrigerator?
The difference in the weight of copper in the compressor of the refrigerator, depending on the "antiquity" of its brand
The “ancient” brand of the refrigerator, the more copper in its compressor. These are the current types of engines I can achieve fabulous efficiency with fairly restrained equipment. Previously, in Soviet times, no one thought that bulky engines “suck” a huge amount of electricity from the network, and the more massive the unit, the more it consumes it.
Today's models are very small and compact, and their efficiency is not less than that of bulky Sovdepovye, but they have an order of magnitude less valuable metal.
We measure the weight of copper
So, before us is the engine of the old model of the Biryusa refrigerator and the engine of the relatively fresh Atlant model. Both models are single chamber, with integrated freezer. How much copper is in the refrigerator of the generation before last?
We take a grinder, the fastest tool for disassembling the engine for scrap, we cut the connecting bolts of the casing, then we cut the metal of the engine itself to extract valuable metal. We put the extracted pieces of copper on the scales, look: about 1200 grams. Here you can add on and tubes brought to the engine - get even more.
Now we are taken for the Atlanta engine. We disassemble, put copper on the scales, look - 800 grams. All the same, it’s not bad, considering that today copper is sold at the price of 200 to 300 rubles. per kilo, and we added at least 150 rubles to the main unit cost. Like it or not, this is the cost of 6 loaves of bread.
Who is "welded" on our wastefulness
Of course, dual-chamber models equipped with two compressors contain more copper. If you are not too lazy to remove it, you can extract up to 1.5 kg of non-ferrous metal at a time. True, they will have to tinker longer, but they will not have to give “free” money to collectors.
Masters, bringing old household appliances to their base, are not lazy at disassembling it. From each household electrical appliance, whether it is a hairdryer, washing machine or refrigerator, they remove the metal and, having immediately handed it over, put our “consumables” in their pocket. And it turns out they have quite a few days! Knowing how much copper is in the compressor from the refrigerator, you can roughly calculate how much money will settle in their pocket if at least three refrigerators and a couple of washers are handed over to them for scrap, even if you take it to a minimum - this is about 1000 rubles.
Anyone interested can see the video disassembly and measurements.
In conclusion - a couple of nuances
The most important thing that you need to know for those who, before handing over the old refrigerator, decides to remove the compressor, remove the color from it and hand it separately: the copper burnt at the stake costs at least 50 rubles. more expensive.
Use caution when disassembling. Freon circulating in the system is a danger to humans, so before you begin to disassemble the unit, make sure that the system is completely empty of hazardous fluids. It is advisable to disassemble the equipment in the backyard, in no case in the apartment.
