The receiver is a metal container that serves as a storage receptacle for the refrigerant. It's also referred to as a
drier because it absorbs moisture from the refrigerant and filters out particles of debris and harmful acids that
would otherwise harm your AC system. Commonly located on the liquid line of the AC system, you should change your
drier every 3-4 years to insure quality filtration and prevent any damage caused by these detrimental chemicals.
The orifice tube (also known as the expansion valve) is a controlling mechanism that regulates the flow of refrigerant
throughout the system. In addition to this, it also converts high pressure liquid refrigerant (from the condenser)
into a low pressure liquid, so that it can enter the evaporator. Generally located at the evaporator inlet, the
orifice tube could also be found between the condenser and the evaporator, or in the outlet of the condenser.
The evaporator is designed to remove heat from the inside of your vehicle; therefore it's a heat exchanger that's
vital to your vehicle's AC system (not to mention your comfort). The evaporator allows the refrigerant to absorb heat,
causing it to boil and change into a vapor. When this occurs, the vapor is removed from the evaporator by the
compressor, cooling your car and reducing humidity. Because the evaporator houses the most refrigerant in this heat
transfer process, it is the most susceptible to corrosion by harmful acids. Usually this damages the evaporator beyond
repair, which is why it's imperative you see us to prevent this from happening.
