Car air conditioning systems have become a mandatory equipment on today's car models. However, not all drivers know how to use car air conditioners properly to ensure long-term efficiency.
In the habit of using cars every day, most users often only focus on starting the car and moving, paying little attention to seemingly unimportant details.
One of them is turning off the air conditioner before turning off the device. Here are the reasons why turning off the air conditioner before turning off the engine should be considered an important habit when using a car.
Helping the air conditioning system operate more durably
Car air conditioners are a complex system of many parts such as a comprformer (cooled Voltage), hot air compressors, air conditioners, fans, drainage valves, etc. Among them, the comprformer is the most important component and only works when the vehicle's engine explodes.
If the user turns off the car while the air conditioner is still turned on, the compressor will suddenly stop with the engine, causing great and uneven pressure on the system.
Over time, this can lead to a cold gas leak, reduced cooling capability, and even broken compressors - a part with cheap replacement costs.
However, if the user turns off the air conditioner while the engine is still running, the compressor will stop working naturally and slowly, reducing mechanical pressure and prolonging the life of the air conditioning system.
On the other hand, turning off the air conditioner before turning off the engine not only helps reduce the starting load, but also keeps the power system more stable, avoiding the phenomenon of "no engine failure" when starting the engine, while saving fuel and improving performance.
Prevent odor and mold in the cabin
Many people experience a foul smell after a period of use, especially during the rainy season or after a long parking period. The main reason is that moisture stagnates in the refrigeration system, creating ideal conditions for mold and bacteria to grow.
To solve this problem, users should turn off the air conditioner about 1 - 2 minutes before arriving, then switch to fan mode. This method helps dry the air conditioners, thereby limiting unpleasant odors and keeping the interior always clean and fragrant, while protecting the health of those in the car, especially in hot and humid environments like Vietnam.
