The air conditioning panel in the car may be the area where many car owners adjust most when driving. The seemingly simple air conditioning panel also has a lot of small knowledge and cold knowledge. Today, I'll take you to "review" the operation of the air conditioning in the car and introduce the differences of various air conditioners in the car. There may be something you need to know.

A / C air conditioning switch

The A / C button is simply the air conditioner switch. Only when the A / C is turned on, the air conditioner in the car will be cooled and warmed normally, and other buttons will be opened for use. It should be noted that the air conditioner of some models will not work normally when powered on. The engine needs to be started to use the air conditioner in the car normally.

It's not too cold outside the car, but if heating is needed inside the car, you can turn on the external circulation without turning on the A / C. the engine heat can also send warm air into the car, which can reduce energy consumption.

Automatic and manual air conditioning

The interior air conditioner can be divided into automatic air conditioner and manual air conditioner. The biggest feature of the model with automatic air conditioner is that there is an auto button on the air conditioner panel, which can keep the interior temperature constant through the known set interior temperature.

Manual air conditioning has only two knobs of air volume and temperature, and can only roughly adjust the temperature in the vehicle.

Use of internal and external circulation

There will be selection buttons for internal and external circulation on the air conditioning panel in the car. When the external circulation is turned on, the air inlet in the engine compartment will be opened, and the fresh air outside the car will enter the car from the air inlet. It is more suitable for driving for a long time or in a place with fresh air.

When the internal circulation is turned on, the air outside the vehicle will not enter the vehicle, that is, only the air inside the vehicle is circulated for ventilation, which is very beneficial to short-term refrigeration. However, if it is used for a long time, it is still necessary to turn on the external circulation intermittently to bring fresh air into the vehicle.

Air supply mode (wind direction selection)

General models are equipped with air ducts with up, middle and down wind directions. In addition to the commonly used middle air ducts, the up and down wind directions can be blown to two areas respectively, which is not only conducive to the cooling of local areas and avoid direct blowing of personnel in the vehicle, but also make the flow direction of air circulation in the vehicle more smooth.

In addition, in addition to the upper, middle and lower winds, some models will have a separate wind direction for blowing the windshield. When the temperature difference inside and outside the vehicle is too large and the humidity is high, the windshield on the vehicle is easy to fog, and the separate wind direction can accelerate the dispersion of glass fog. For example, some high-end models will be equipped with heating wires in the glass interlayer. Starting the heating wires also has this effect.

Zone temperature control and synchronous temperature control

In some high-end cars, in order to meet the different requirements of members in different positions on the air temperature in the car, the space in the car is often divided into several independent temperature zones, and each independent temperature zone can be adjusted differently. The more complex can be divided into four zones, that is, the left and right passengers in the back row can also adjust the temperature around themselves. The partition air conditioner can also be set to "synchronous", which is controlled by one person, and the air outlet temperatures on both sides are the same.

In today's life, everyone can't live without the air conditioner. After starting the vehicle, everyone is used to adjusting the air conditioner at the first time, but the seemingly simple air conditioning adjustment still has many places to pay attention to. Understanding the air conditioning system of their own vehicle can make driving easier.
