Air conditioning in a car is an absolute necessity, especially when you’re on a long drive during those hot summer days. Not only does it provide the people in the vehicle with the right amount of air, it also stops you from having the window opened and inhaling the fumes from the cars around you.
You may be wondering how the cooling unit in your car works, or up until clicking on this article, may have never thought about it. Cooling systems were first placed in cars in 1939, and since then, most vehicles are fitted with one.
Automotive air conditioners are made-up of four parts. The compressor is the core of your air conditioning unit, it takes the refrigerant gas and pressurises it, making it nice and cool.
The condenser is at the front of the car and is like a radiator, as the compressed warm air passes through the condenser, it gets cooler. The evaporator does the opposite job, as the cool liquid passes through the tubes; air is pushed through and gets cold. As soon as it warms up, it then turns back into a gas.
The thermal expansion valve controls the flow, allowing you to decide on how much or how little air you want to be coming out of the valves.
Maintaining your cooling unit and ensuring that it’s functioning to its full capacity is important, especially throughout those warmer days.
