Why vehicle air conditioning compressors fail more during summer

Why You Sell More Air Conditioning Compressors During Summer?



Understanding the role of air conditioning compressor in a vehicle is very crucial, this not only makes it easier to visualize what it does and what role it plays, but also helps in identifying a quality replacement compressor when needed especially during the summer. The first step in understanding the compressor and the vehicle is learning the basics of air conditioning mechanisms.
A liquid refrigerant is constantly cycled throughout a sealed system. This creates a repeated process of vaporization, liquid location, and re-vaporization. As this process occurs, the gas gives off heat to condense the refrigerant back into a liquid. If the refrigerant gas is pressurized, it becomes easier to liquefy it. The air conditioner of a vehicle operates on these basic cooling principles. The principle states that liquids absorbed heat when they become a gas. While extremely simple, this is proved to be an effective principle in all types of cooling systems.
In a vehicle, the entire cooling process is actually powered by the engines drive belt. The compressor liquefies refrigerant and sends it to the cars air condenser. The highly pressurized refrigerant then becomes a gas which is constantly circulated into tubes. This is where the heat from the gas is released, allowing it to cool. As it cools, the refrigerant reverts back to its liquid state and is returned to the compressor. It is in this liquid form that the refrigerant is used to cool the interior of a vehicle.
It can be difficult to know exactly how long the compressor will last, however there are several key factors which can be used to determine how durable the compressor will be. The first sign of a durable air conditioning compressor and the vehicle is minimal vibration and noise. The more a compressor vibrates, the more stress and pressure is put under. Undue stress inherently leads to premature breakdowns. This is exactly what happens during the summer period because of the air conditioner will overwork itself so as to ensure the inner part of the vehicle is cooled. This will result into the breakdown of the compressor thereby making more people purchase air conditioning compressor as a replacement.
When choosing a replacement air conditioning compressor, it is important to consider not only durability but also energy efficiency and safety. The more energy-efficient the compressor is the less power your vehicle will need to ensure it is always running properly. This is particularly important when living in hotter climates in which the air conditioning will be used regularly. Most air conditioning compressors include some type of safety system. The most common is a relief valve. The relief valve is there to ensure too much pressure does not build up within the compressor.
Some of the issue car owners have which can contribute to a lacklustre breeze in their vehicle include the following:
•Refrigerant leak
•Electrical problem
•Incorrect refrigerant level
When there is a refrigerant leak in your vehicle, the air blowing through the vents does not get cooled to the temperature you set from inside your car. This can make air that is supposed to be cold, blow out at room temperature. It is important to fix the leak as soon as it is identified because air and moisture that enters the air conditioner can ultimately damage the compressor, the pump that compresses and transfers refrigerant gas. This can however lead to the increase in sales of compressor because this occur frequently during the summer period.
If your car has an electrical problem, this means the fan, or blower motor, has stopped working. As a result, air no longer blows through your vents properly. Dust or debris could be the culprit behind the malfunction, though it could also be the result of a blockage or even a faulty electrical connection. Removing an obvious blockage may solve the problem, but if it is an electrical connection, the problem might be more serious.
A third common A/C issue is incorrect refrigerant level-either too much or too little will cause your car's air conditioner not to work properly. You know this as a result of excessive noise coming from the A/C compressor or the air conditioner is cycling on and off too frequently. Irregular maintenance of your vehicle contributes to each of these problems. Just like your home's heating and cooling system, your car's A/C should be checked at the beginning of each season. Checking in the winter is just as important as in the summer, when you are more likely to be using cool air.
So, if your temperature is not cold enough, you hear too much noise coming from the A/C compressor, or if the A/C is not cycling on and off properly, it is time to get a new compressor.
The maintenance of your car air conditioner is very essential because it will ensure the longevity of your compressor. However, there are some steps which are to be followed so as to ensure your vehicle is in the appropriate working condition. So as to have a good understanding of these maintenance, ensure you keep reading this content.
1. The first step you need to consider in maintaining your car conditioner is to read your owner's manual for your vehicle. Commonly, this kind of manual guidance is fulfilled with maintenance list which will cover the typical life span of parts for your car. When discussing the air conditioner in your car, you need to know that it has some parts that must be handled very well so you can get the best solution to handle them. Those parts include the compressor, evaporator, hoses and belts.
2. The next step you must do is to have a mechanic who will do inspecting of the unit each spring. In this case, you know very well that the drive belt of compressor will need to be inspected for damage and its tension adjusted. Also, the level of refrigerant must be checked and replaced if necessary. Based on that fact, it is important to do checking regularly so you can prevent the bad thing that can happen to you.
3. Also, it is important for you to maintain the coolant pressure with running the air conditioner once a month for ten minutes. This kind of process maintenance will help you to prevent your hoses hardening and the seals failing. In this process, you must turn the air conditioner to its coolest setting and highest fan speed so you can maintain it very well.
4. After that, it is also an essential thing to dry out the evaporator core after running it for an extended period of time. In this case, you are advised to run the cars defrost for five to ten minutes because this process is functional to clean out any accumulated moisture. In fact, this kind of process is done to prevent mildew and odours in the system.
If these maintenances are not carried out appropriately or the air conditioner of the vehicle overwork itself especially during the summer, the compressor would get spoilt. This is the main reason why more air conditioning compressor are sold during the summer period.
