Auto Ac System Diagram. See how they work with a diagram. Thermal expansion valve 6. Ever wondered how the AC system takes hot outside air and turns it into cool refreshing air from the vents? Compressor 2. It collects water condensed from the cooled air and produces hot air which must be vented outside the cooled area; doing so transfers heat from the air in the cooled area to the outside air. The orifice tube, probably the most commonly used, can be found in most GM and Ford models. A compressor provides pressure rise to the refrigerant to convert the vapor refrigerant into liquid refrigerant which in turn enables the further flow of the refrigerant through the condenser. Introduction of liquid refrigerant into a compressor can do serious damage. As the gas cools, it condenses and exits the bottom of the condenser as a high-pressure liquid. From there it goes to the heater, which warms it if required. The desiccant is used to absorb moisture (water) that may have gotten inside the A/C system during manufacture, assembly or service. Such a system dehumidifies the air as it cools it. Receiver-drier A wiring diagram is often used to fix troubles as well as to earn certain that all the links have been made which whatever exists.
