The Air Conditioner

It is almost unheard of these days to not own an air conditioner to cool your house. But there are a rare few out there. Air conditioners have been a round for a long time. Today they are becoming cheaper and more environmental friendly. So who wouldn’t want one?
You might know what the air conditioner is but you probably don’t know how it actually works. Usually you will see a square or circle unit sitting up on some kind of pad. What is the pad for? The pad it sits on is the unit can sit level and not sink in the mud. As you look closer from the top; you will see a big fan through a grill looking thing. This is to draw the hot air from the coil that surrounds the entire unit. The coil consists of copper pipes running through these little aluminum fins. The coil is surrounding this black cylinder that sits in the middle on the bottom. This is called the compressor; it all starts here. A compressor is more or less like a pump. It has to different size copper pipes running out of it. The compressor pumps a gas called refrigerant through these two pipes which go inside. Each pipe takes the refrigerant in a different direction.
From the outside unit these copper lines bring refrigerant to an inside coil also known as a furnace. The gas changes into a liquid before entering the inside coil. This is where you get your cold air from.
