how ac system works in car

The low-pressure liquid refrigerant moves through the evaporator. It serves one very fundamental purpose, as well, and that is to cool you down. Learning about the basics of your car’s AC will help you not only understand the little details how the auto AC system works to keep the temperature nice and comfortable. If the power came from an ordinary battery, it would soon run down.So a car has a rechargeable battery and a charging system to keep it topped up. As the name suggests, it “compresses” the refrigerant so that it turns from a gaseous state into a liquid state. We take for granted the heat that keeps us warm in the winter months, and the cool air that refreshes in the summer time. If not, ice crystals can form and lead to blockage and mechanical damage. While all the other parts of the system are located in the engine compartment, this one is in the cabin, usually above the footwell on the passenger side. All three of these modes make up the climate control system that is incorporates in the hood of your car. Air conditioners in cars. When the refrigerant reaches the condenser, it cools and liquifies. Condenser – It is the device looks like a small radiator and is used after the compressor as it provides condensing i.e. < Professional Oil Change: How Frequently Does Your Car Need One, A Brief Guide to Summer Road Trip Prep: Stay Safe & Have Fun >, SEE OUR OTHER INFORMATIVE AUTO REPAIR & MAINTENANCE ARTICLES, How does your computerized air con system work? A desiccant removes moisture that may be present in the refrigerant. Your heater and air conditioner (HVAC) have three jobs, cool the interior of the car down, heat the interior up and defrost the windshield. You climb into your car on a sweltering day, crank the A/C, and get blasted by nothing but hot air on the entire ride home. Learn how your comment data is processed. This is also the reason why you should know even when you choose the heat settings on the controls, the air conditioning is still functioning. The thermal expansion valve is the boundary between the high-pressure side of the system (including the compressor, condenser, and receiver) and the low-pressure side of the system. How does it do this? Sitting right in front of the radiator, the condenser’s main job is to cool down high pressure gasses, turning them into liquid. Fans help blow the cold air through the vents and allow the cooling of the cabin. What comes out of the AC vents is cold and dry air. As a matter of fact, it would be quite difficult to imagine a modern vehicle without some means of providing a cooler and more comfortable ride especially when the scorching sun of summer unleashes its wrath. The recent scorching climate may have prompted you to learn how to work your car’s AC to regulate the high temperatures. The pressurized liquid refrigerant circulates through the series of tubes located in the condenser. An automotive air conditioning system works a lot like the AC system that you have at home or the office. Poorly performing and non-functional air conditioning system can be quite annoying. But you might just pick on a few important details on how to know when one of the components isn’t working. Look- the air conditioning system does not get malfunctioned so often. How To Vacuum AC System – A Step By Step Process. Among all the components of the modern vehicle AC system, the evaporator is the only one that’s located inside the passenger compartment. The refrigerant passes around the whole structure and evaporates at low temperature and condenses under high pressure. The compressor then starts the whole cycle again by taking in low-pressure refrigerant vapor. The refrigerant moves into the accumulator or receiver drier. Because of the expansion, there is a reduction in pressure. This leads to the creation of a cooler refrigerant while also maintaining the integrity of the system. A car air conditioning system consists of a compact version of the components of the normal air conditioner that has an evaporator, compressor, condenser, expansion device, and a fan which are fitted in a car to provide air condition inside the passenger’s compartment. It doesn’t produce it. Car air conditioners work to make our rides more comfortable and our journeys a lot more worthwhile. How car heating and ventilation systems work Modern cars are designed to have a constant through-flow of fresh air that keeps the interior atmosphere pleasant even with all the windows shut. The rest of the components are in the engine bay. Once the refrigerant is liquefied, it is sent to the receiver-dryer. The compressor compresses or pressurizes the refrigerant, turning it into a liquid form from its gaseous state. If you need to do some work on your car or truck's AC system, be sure to have a repair manual specific to your vehicle. Incoming air goes through the water-heated matrix and is warmed. Without the heating and air conditioning systems in today’s modern vehicles, we would all be miserable driving to our destinations. Get Directions, Business Hours So before going to know how long to vacuum AC system, let’s take a look at the way of vacuuming AC system. It was designed to solve a humidity problem at the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, N.Y. Paper stock at the plant would sometimes absorb moisture from the warm summer air, making it difficult to apply the layered inking … Imagine the AC compressor as a tiny engine that works similarly to the engine that runs your car. The condenser is the component that converts gas into cooled liquid. This site uses Akismet to reduce spam. Well, read on. Cold air from the receiver-drier moves through the evaporator core. This process generates a great deal of heat, which is then removed by the air flowing outside the condenser. Air conditioning does several things to condition the air passing through a space, in this case the driver and passenger area of your car. Here is an easy guide that you can do by yourself. CAR AIR CONDITIONER. When the component receives the low pressure and cold refrigerant, it removes the heat from inside the cabin. What happens is that heat moves from the liquid and into the air. In general, air conditioning systems operate in the same way. It is best to get familiarized with the different components of the vehicle passenger cooling system to better understand the process of air conditioning. The summer months can make driving just about unbearable if our vehicle AC is not working. When the refrigerant expands, it drips to the evaporator. So, if someone asks, ‘how does a car AC work?’, you already know how to explain it. Not only does the car A/C regulate temperature, it also regulates and reduces the humidity present in your vehicle. Within the A/C, thermodynamics are at play. The five main components of an air conditioner, namely compressor, condenser, expansion valve, receiver-dryer and evaporator, connect to each other via a series of flexible pipes and tubes. This is especially true when you talk about hot summer days and that unbearable humidity. It serves as a reservoir for the refrigerant while also removing any moisture that may be present in the refrigerant. The water vapor or moisture in hot air condenses to form a liquid state. What happens now is that the air exiting the evaporator is cold air. A perfectly working air conditioning system is the key factor in making your daily commute to work and back less stressful. Many consider the compressor as the heart of the air conditioning system of the car. The Nash-Kelvinator corporation used its experience in refrigeration to introduce the automobile industry's first compact and affordable, single-unit heating and air conditioning system optional for its Nash models. Because the condenser contains a higher-temperature liquid, there is a temperature gradient between the liquid and the fresh air. Since any moisture that is leaked into the refrigerant can be dangerous for the components, the receiver-dryer removes it all from the refrigerant. In elementary science, we learned that condensation results from the rapid cooling of hot or warm air. As such, it draws its power from the engine.
