Let’s talk about air conditioning. Most of us in St. Louis don’t give our air conditioning a second thought as long as it works when we turn it on. But it’s a complex and expensive system that we should spend time thinking about before it starts blowing hot air. The air conditioning system in your vehicle performs four basic functions: cooling, dehumidifying, cleaning and circulation of the air in the vehicle. As the refrigerant goes through all of the four phases of compression, condensation, expansion, and vaporization it goes through its own changes. During the condensation phase, heat transfers out of it and into the surrounding air and it expands, then when it evaporates, it absorbs heat to cool the air in the surrounding area. As the refrigerant runs through all of the phases of the cycle, it goes from liquid to vapor and then back to liquid and so on. The main parts of the system are the refrigerant, the compressor, a condenser, an evaporator, a receiver-drier, blower and some switches and valves and an array of cooling lines and hoses. The compressor normally has some sort of magnetic clutch as well. The compressor in an AC system has special oil that is used to lubricate the compressor and the entire system. It actually mixes with the refrigerant and travels through the whole cycle to keep everything running. You may hear some of these parts named when you bring a vehicle in for AC service.
