For car owners, the most difficult is the hot summer, the outside air temperature is super high, after a long period of exposure to the car, the temperature inside the car is even as high as sixty or seventy degrees, according to the latest test data, the external temperature of 35 ° C, the car is closed for 15 minutes, the temperature in the cabin can be as high as 65 ° C, in order to highlight the grade of the vehicle interior, the color of the car interior is generally designed as black or darker color, the deeper the color, the stronger the absorption effect of it on the sun, if the space inside the car is closed, The temperature inside the car will rise rapidly. In this case, the car air conditioner seems to have failed. In fact, when driving in the summer, the air conditioner operation has a knack, master the correct way to open the air conditioner, the owner can enjoy the cool summer!
Open the doors to create an air convection
After a day of exposure to the car, although the temperature inside the car is very high, it can be quickly cooled, the main reason is that the amount of air in the car is limited, the owner only needs to discharge the hot air in the car, enhance the air convection inside the car and outside the car, and the temperature inside the car will be rapidly reduced. Before the owner of the car drives, first open the door of the passenger seat or shake the car glass, the owner fans the main driver's seat door back and forth, according to the "principle of the fan" back and forth a few times, accelerate the convection of air in the car, the temperature in the car can be rapidly reduced. If the temperature in the car is 65 ° C, about 5 times the fan, the air temperature in the car can be reduced to more than 50 degrees, is it not amazing?
Turn on the air conditioner of the car and open the windows at the same time
After the owner enters the interior of the vehicle, first start the engine, and then open all the windows, open the vehicle air conditioning, start the external circulation, at this time the air blown out of the air conditioning outlet is hot air, the owner does not rush to close the window, do not rush to close the air conditioning external circulation. Think about it, after a day of exposure to the sun in the car, is the temperature in the engine compartment and in the air conditioning outlet duct also very high? If we are in a hurry to close the windows of the vehicle, the hot air blown by the air conditioner will quickly fill the interior of the car, and the temperature inside the car will definitely be higher.
In this case, the owner can drive the vehicle at a low speed, allowing the outside air temperature to enter the cab, which helps to reduce the owner's body temperature.
After the air conditioner is cooled, the internal circulation is turned on and the windows are closed
After the air conditioner starts for a minute or two, the air conditioning compressor begins to work, at this time, the air blown out of the air conditioner outlet is the cold air, in this case, the owner closes the car window, while opening the air conditioning internal circulation, about five minutes, the temperature in the car will become very comfortable.
Why open the internal circulation of air conditioning? To explain the meaning of the internal circulation, the internal circulation refers to the air inside the car is sealed, the air conditioner first draws out the hot air from the vehicle cab, and then releases the cold air to the cab, the hot air outside can not come in and out, due to the limited space inside the vehicle, the amount of air in the cabin is also limited, and the refrigeration effect of the air conditioner will become more obvious.
Car air conditioning internal circulation, although it will increase the cooling effect of air conditioning, but let the air in the car become abnormally turbid, long-term breathing of such air, the owner will also become physically and mentally exhausted, so after the internal temperature of the vehicle is fully reduced, it is still recommended that the owner open the external circulation.
In summary, the summer heat is not terrible, master the appropriate air conditioning control method, the owner can definitely spend a cool summer.
