In this video, you will learn about air conditioning. When you look at a typical air conditioning system: you have a condenser, a compressor, an expansion valve, and an evaporator. The condenser and the evaporator are both heat exchangers.

The condenser sits inside and cools while the compressor circulates the air. Refrigerant is used to help the system properly cool air. Refrigerant is a special type of material that can switch between liquid and gas very quickly. That is because it has a low boiling point. It boils at -55 degrees Fahrenheit. The expansion valve is the middle ground between the condenser and the evaporator. The refrigerant flows on the inside of the expansion valve, which causes it to boil and absorb the heat through the air. As the refrigerant evaporates, it carries away the heat. This is similar to how we boil water. The water is boiled and then turns to vapor and is carried away. Liquid damages the compressor, so there are usually never droplets of liquid once it is turned to vapor. To learn more about air conditioning units, keep watching the rest of this video.

About Me

I've seen a lot of cooking, home improvement and crafting shows and, let me tell you, they make things look way easier than they are. Most people really can’t remodel their own kitchen, paint a wall mural or whip up a gourmet meal in an afternoon. I’m here to share my ideas and guidance about home and family--things I've learned through trial and error. I've already made the mistakes so you don’t have to! Just don’t ask about the kitchen cabinet refinishing project that went awry.
