Central AC units

AC freezing upward? How tin something that works all day during the hottest days of the year be prone to freezing? Despite the ironic happening of an Air-conditioning freeze in the summertime, air conditioners freezing up is something that happens a lot.

The aforementioned works in reverse, cold air is comprised of low energy molecules. So, what the Joule-Thomson Outcome demonstrates in thermodynamics is when the air in our ACs isn't compressed, its temperature will decrease as it expands and the molecules ho-hum. When it is compressed, the molecules go excited and heat upward.

The betoken of an air conditioner is to expand the refrigerant inside the evaporator gyre so that it cools down, so when information technology leaves the air conditioner, it cools the air inside your habitation and effectively removes the hot air from inside the house. Nevertheless, if something in the air conditioner malfunctions, the whole system gets disrupted. This causes the evaporator curlicue to allow the refrigerant to cool too much, causing it to fall below freezing and water ice over.

So, how can you forbid something in the cooling equation from going terribly wrong? There are iii main causes that atomic number 82 to an AC freeze up. By understanding these causes, you can go out in front of them so you never accept to experience an Ac freeze.
