What Does The A/C System Comprise Of?
Many of us know how important A/C systems are. They cool the air moving inside the vehicle to make sure you will feel comfortable while you are taking the road especially on a hot summer’s day. The air is blown inside the cabin over that of an evaporator or a cooled surface. This will then transfer the heat coming from the air to a specific coolant that flows through the entire A/C unit.
There are many different parts of the A/C system that have their respective functions to make the entire system work according to its purpose. Among the parts of the system are the coolant cooler, water pump, thermostat, heat exchanger, air flow, engine, radiator fan, and the engine. An optional part is the heat exchanger valve. More specific parts of the air conditioning system are as follows.
The Compressor and Condenser
The A/C system cools only after Freon and a specialized type of oil has been pumped through the system. This process is made possible by a vital part of the unit called the A/C compressor. Any fluid that leaves the compressor passes through a drier specifically a filter. Any debris found in the mixture of the Freon and the oil will then be captured by the compressor.
From here, the compressed fluid will then be passed on through the condenser. This is the part of the unit that expands the fluid to provide more room or surface area with which air can easily move and pass by. Once the air passes through the condenser, excess heat will be pulled off from the compressed fluid which will mean that the air can be cooled so that the A/C system can perform according to its purpose.
Expansion Device and Evaporator
Cooled air from the compressed fluid will then pass through the expansion device, a part which is responsible for carrying the fluid. As the name implies, the expansion device expands the fluid thus allowing it cool even more. From here, the fluid will travel through another part, that is, the evaporator. This part is where the heated air can be absorbed again signaling that the entire process of cooling will start over again.
Accumulator and Orifice Tube
There are also other parts that make the car A/C system work. One is the accumulator which is also known as the system’s holding tank that is responsible in holding the refrigerant that comes out of the evaporator. While the refrigerant is held inside the accumulator, the desiccant bag will then remove any moisture present in the refrigerant. The orifice tube, on the other hand, is responsible in restricting the flow of the refrigerant. The restriction will then allow the transformation of the once high-pressure refrigerant into a low pressure one right before it gets inside the evaporator.
Take note that these parts are very vital in the A/C system operations but in order for the system to cool, the air temperature is a factor to consider. The air that travels around the system, in particular, will dictate the temperature given off by the system. This explains why A/C systems tend to be hotter during a summer day when compared to winter.
