You probably wonder why your refrigerator is often plagued with ice buildup and condensation, or maybe you thought it was just because it is cold? That isn’t all there is to it, continue reading to find out why.
First, water vapour is just water in gas form. Evaporation is the conversion of Refrigerators, like air conditioners, dehumidify the air inside by cooling it until the water vapour in the air condenses into liquid water onto the evaporator. That liquid water then flows into a water collection pan underneath the fridge. There isn’t much, and it eventually evaporates, so you don’t have to empty it yourself.
Despite the fact that refrigerators dehumidify themselves, the food and drinks that they contain consist of water that evaporates into air in the fridge and then is eventually condensed into liquid water, and it finally freezes, this processes gradually takes place, and on top of the ice that is already in the fridge, more water keeps condensing and freezing onto it in layers and the chunks of ice keep growing until you can’t open drawers, or have other problems.
Some of the sources of water vapour include glasses of water and juice, all other liquid beverages in opened cans and bottles, as well as vegetables. Vegetable leaves especially transpirate the water that they contain into the air in the fridge, and it sometimes ends up as ice on the wall or vents too.
Another contributor to the problem is setting the fridge to a temperature that is too low. Try to find the ideal temperature. Your thermostat could also be failing to turn the refrigerator off when it is cold enough, so it stays on and gets colder until it freezes.
Defrosting is the process of turning off the refrigerator so the ice in it thaws, as was being done in the picture at the top of this page.
