What is a Refrigerant? How Does a Refrigerant Work? Explained!

In this HVAC Video, I explain what a Refrigerant is and How it works. I explain what is happening to the refrigerant as it moves through an air conditioner or refrigerator. We compare R-22 to other refrigerants that are well known and explain how pressures and temperatures affect the refrigerant. I also go over how the refrigerant affects the building air and the outside air. I go over some of the things that are happening during the refrigeration cycle. The pressure-temperature relationship is discussed. I also go over what the saturated state of a refrigerant is.
