Moreover, you have to understand that the heat under the hood of your car can travel inside. This causes the interior temperature to rise, which can be uncomfortable. Not to mention if the temperature is outside is blazing, you’d be better off taking a cab to work.

Understanding How the Climate Control System Works

The climate control of your car is a complex system. It involves a number of processes in order to cool, circulate and even purify air. The most important component of such a system is a refrigerant as it is responsible for not only removing hot air and heat from inside the cabin, but also producing cool for cool air. Another important component of your climate control is the compressor that transforms hot gas into a liquid, which the system then cools. This series of processes also depends on a number of other components such as the evaporator, condenser, etc.

However, like most of the parts and systems of a car, it is important to maintain your car’s climate control. If you don’t take good care of the system, a number of potential problems could surface. The first and most obvious problem that would occur due to poorly maintained climate control is slow or less heating and cooling. Therefore, it would take a lot of time for the system to bring the temperature inside your car to an optimum level.

Why Professional Climate Control System Repair is Important

Furthermore, if you have not sent your car for a complete AC overhaul, the air filter that traps bacteria, dust, pollen, and other particles and does not allow them to enter the car’s ventilation system might get clogged. This means the flow of air will be quite polluted and might cause musty odors inside the cabin. Various harmful gases could also find their way inside the car making the air inside dangerous.

Moreover, a bad climate control system will drain your engine’s power. This is because it requires a constant and consistent supply of power. This in turn can lead to various complications – your fuel efficiency will worsen and the mileage will also decrease. Similarly, various mechanisms of the climate control system need to function more than their capacity. This increases the risk of damage or total failure.

If you want to keep yourself from costly repairs and high fuel expenses, have a professional mechanic service your car’s climate control system once every year or after every 4000-5000 miles. This would improve your car’s overall performance and allow you to drive comfortably in extreme weather. Moreover, you enjoy a pleasant and healthy environment inside the cabin every time you drive the car.

Well, it looks complex to most people, but is actually quite simple to understand. 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. But you might just pick on a few important details on how to know when one of the components isn’t working.

The auto AC system has three jobs in total – (1) Increase the internal temperature in your car (in winter), (2) cool down the interior and (3) defrosting the windshield. All three of these modes make up the climate control system that is incorporates in the hood of your car.

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. The refrigerant passes around the whole structure and evaporates at low temperature and condenses under high pressure.

Components of the Auto AC System

Compressor

The compressor is the driving force of this system and gets its power from the engine’s crankshaft. This sends the pressurized refrigerant vapor to the condenser once the belt connecting the compressor and the crankshaft starts running.

Condenser

Sitting right in front of the radiator, the condenser’s main job is to cool down high pressure gasses, turning them into liquid. When the refrigerant reaches the condenser, it cools and liquifies. This process generates a great deal of heat, which is then removed by the air flowing outside the condenser.

Receiver-Dryer

Once the refrigerant is liquefied, it is sent to the receiver-dryer. Since any moisture that is leaked into the refrigerant can be dangerous for the components, the receiver-dryer removes it all from the refrigerant.

Expansion Valve

The receiver-dryer then sends the pressurized refrigerant to the expansion valve. This part literally allows the refrigerant to expand by removing pressure from it. When the refrigerant expands, it drips to the evaporator.

Evaporator

Looking a lot like the radiator of the car, the evaporator sits inside the cabin. When the component receives the low pressure and cold refrigerant, it removes the heat from inside the cabin. The blower fan then circulates cold air by pushing it via the evaporator.

The compressor then starts the whole cycle again by taking in low-pressure refrigerant vapor. You can control the speed of this cycle by regulating the setting of the expansion valve. The basic principle of air conditioning is same for all systems, even if there are any variances in any or all parts of the AC or climate control.
