HOW DOES A FRIDGE WORK?
It all starts with the compressor (1), a large bicycle pump powered by a motor. This motor pushes a special gas through a long steel coil called the condenser (2), where the pressure reaches between 10 and 15 atmospheres, causing it to liquefy at a temperature of 45 degrees Celsius. Next, the expansion valve (3) reduces this liquid to atmospheric pressure, transforming it back into a gas while lowering its temperature, similar to the effect of an air freshener when you press a button. Finally, the gas circulates through a large coil (4) in the refrigerator shelves, thus cooling the entire unit.
The faster the compressor runs, the lower the temperature drops. This all needs to be regulated!
