How to drive the air conditioner in summer?

The correct way to turn on the air conditioner in the car in summer is to turn on the external circulation of the air conditioner first, so that the hot air in the car can be discharged first, and then turn on the air conditioner after the temperature in the car drops obviously.

Introduction to the misunderstanding of automobile air conditioning;

1, select the appropriate air conditioning temperature.

Of course, in summer, many people like to keep the temperature very low. As we all know, too low temperature adjustment will affect your health, so the temperature adjustment of air conditioner must be appropriate.

The most suitable temperature for human body is 20℃ to 25℃. If it exceeds 28℃, people will feel stuffy. And below 14℃, people will feel cold. Therefore, the air conditioner should control the temperature inside the car between 18℃ and 25℃, and people are prone to get sick if the temperature is too low.

2. Enter the car in summer and start the internal circulation immediately.

Cars are parked in the hot sun for a long time. Some car owners like to turn on the air conditioner and start the internal circulation as soon as they start the car, thinking that this can make the temperature in the compartment drop faster.

But because the temperature inside the car is higher than that outside the car, the effect is not good. When you first enter the car, you should first open the window for ventilation and start the external circulation to exhaust all the hot air. After the temperature in the carriage drops, it is replaced by internal circulation.

It is known that air conditioner should be used in a totally enclosed state.

The same is true for car air conditioners. If the doors and windows are not tightly closed during use, the refrigeration effect will be poor and fuel will be wasted.

4. The direction of the air outlet can be adjusted at will.

Some car owners do not pay attention to adjusting the blowing direction of air conditioner when using air conditioner, which is not conducive to achieving the best effect of air conditioner. According to the principle that the cold air sinks and the hot air rises, the correct way should be that the air outlet is upward when the cold air is turned on and downward when the heating is turned on.

Leave the air conditioner on for a long time.

Some car owners always turn on the air conditioner after getting on the bus, but using the air conditioner for a long time will make the condenser pressure too high and cause losses to the refrigeration system, because the air conditioner is a heavy burden to the engine, which is itself a heater, not to mention in high temperature weather.

In this case, some cars with small displacement even have water boiling, which affects driving and reduces the efficiency of air conditioning. Therefore, it should not be too long to use the air conditioner every time. If the temperature inside the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on later.
