Have you ever wondered if a refrigerator can cool down a room? They usually say no, but I’ll say it’s possible. But all is not so simple.
First you need to understand how a refrigerator works. If you know, you can safely scroll down to the designated line. Nope? Then. Thermodynamics equals…uh…high. Entropy is closed… so stop again. Let’s simplify everything as much as possible.
So, introduction. In nature, it is arranged in such a way that if you put a warm object next to a cold one, the warm object will get colder and the cold object will get hotter until their temperatures are the same. And of course if you don’t continue to cool or heat it further. It is clear that the boiler included in the network in a bucket of cold water will heat up and not cool down. I think this is understandable.
And this is where our special agent-hero comes into play. And this is not agent 007, but a coolant. Why does the refrigerator gurgle? This is the exact same coolant in it and it moves.
Have you seen what happens if you puncture a can of deodorant or unscrew the spool of an inflated tire? It will be cold, cold. The wheel chamber nozzle will usually be covered in frost. In summary, this is a very important point. With a sharp drop in pressure, the temperature also drops.
So, in the refrigerator there is a specially designated part for this: evaporator. There, the refrigerant quickly converts to a gas from a liquid (I’ll skip the part about capillaries here), meaning your blood pressure drops. And in the evaporation chamber it becomes very cold. And through the next wall we have warm products. What did I say a couple of paragraphs above about what happens if you put warm next to cold? Correctly! Your food will get colder and the refrigerant will get a little warm. It will get a bit hot, because you have a 7 liter pot of borscht and there is much less refrigerant.
But his borscht stops, and the spent coolant flew to the back of the refrigerator, where there are a bunch of all kinds of tubes and a warning not to block them and not to put them near the wall. Have you heard that there is a compressor in the refrigerator? And you hear it yourself every day. It builds up pressure and the refrigerant becomes almost liquid (also very hot). It then passes through all of these radiator tubes and dumps excess heat through them, turning to liquid entirely.
Why can’t the refrigerator radiator be covered? Yes, because the cooler the air in the radiator, the faster it will cool down and the better it will perform. Which slide will you slide faster, 5 meters or 20 meters? The greater the height difference, the faster. So with the radiator, the greater the temperature difference between the radiator and the air around it, the faster it will cool down.
Op, and here’s the line between those who knew before and those who know how the refrigerator works now.
And now the main thing. You open the refrigerator door and a cool breeze blows on you. Okay… Except (let’s simplify it to understandable computer game parlance) 100 cool points you get from the refrigerator doors converts to 120 heat points escaping out the back.
So yes, if you stand right in front of the open refrigerator door, you’ll be fine. Until, over time, that excess heat built up in the back of the fridge heats the room to a completely unpleasant temperature. Well, remember school assignments like “7 l/s were poured into an empty bath and 5 l/s came out”? These glasses of extra heat will gradually warm up the room.
“Hey now!” – you say, – “you said that you can cool the room with a refrigerator!”. Well yes, she did. They can. In front, she cools down hard and main. The problem is that it gets hotter from behind than from the front. So all it takes is just put off is located in the back of the refrigerator excess heat somewhere far away outside, Out of the room. Let it heat the air somewhere. So, you can put a refrigerator in the doorway, place it around the perimeter, and voila, let it warm the hallway or the next room. You’ll get freshness from the open refrigerator door. Well, or not put, but put there outside there is a fan next to him, let him blow the heat somewhere there.
Not really, right? I agree. Then you can make it easier. Lay these tubes where the refrigerant goes through and have it be compressed by the compressor and discharge the heat, and just collect the excess heat in the room. And it is even better to install a fan in this part, so that a cool breeze walks throughout the room, and not just next to the refrigerator.
I stop though… did it turn out to be an air conditioner?
I hope you have received an answer to your question about whether it is possible to use the refrigerator as an air conditioner.
