When the warm air is not turned on, the temperature adjustment button of the air conditioning system can be placed in the middle of the heating and cooling switch. The warm air is not turned on, and neither the air conditioner nor the warm air is turned on. At this time, you can turn the temperature adjustment button of the air conditioning system to the middle position of the heating and cooling switch, because this will cause the air damper of the air conditioner to adjust the air temperature only to isolate the water tank from the hot air.
Even the wind blown by the fan only passes through the evaporator box of the air conditioner instead of hot air and water. The water tank and the air conditioner are not working, so the evaporator box is also indoor natural temperature, and the wind blown is also natural wind. In fact, there are many small details that must be paid attention to during the use of automobile air conditioners.
For example, in winter, due to the large temperature difference between inside and outside the car, the window glass fogs, which affects the line of sight. There is a special window defogging function. Whenever it is opened, the windshield defroster blows on the glass through the air outlet of the air conditioner to remove water vapor, and the fog can be dispersed.
Generally speaking, when blowing glass, turn on the air conditioner switch, and the defrosting effect of cold air is faster and better.
Also, in the hot and cold season, many people turn on the air conditioner as soon as they get on the bus, in order to be more comfortable. The air conditioner can be turned on in summer, and the compressor can work to blow cold air. In winter, air conditioning is heated by engine water temperature, which may be the heat source of air conditioning.
It's best to wait a few minutes to observe the rise of engine water temperature before turning on the heating and air conditioning. The way to turn on the hot air in the parking state is to set the circulation mode of the air conditioner to internal circulation, and then turn the temperature knob to the red area. Some models are represented by the sun.
At this time, there is no need to press the air conditioner switch, the air conditioner is cooling, and the car heater can use its own thermal cycle to supply heat. Adjust the gear to the appropriate gear, blow forward or downward, and don't let the hot air stay for a long time with the window closed, otherwise it will cause carbon monoxide poisoning to the drivers and passengers.
The combination of internal and external circulation can make the air in the car fresh and better protect the safety of drivers and passengers. In addition, the car mainly pays more attention to the maintenance and maintenance of air conditioning, and regularly checks the coolant content. If the refrigerant is not added for a long time, the refrigeration effect of the air conditioner will become worse.
In fact, the temperature adjustment of air conditioner is only used to choose a comfortable temperature when it is on. There is nothing else to pay attention to, and the owner need not worry too much. On the contrary, when the air conditioner is turned on, in order to make the temperature inside the car reach the predetermined temperature as soon as possible, the internal circulation can be turned on first, that is, there is a C in the middle and a button printed with a car pattern outside.
Internal circulation isolates the air circulation inside and outside the car and can quickly change the temperature inside the car. But after a long time, because the air is not circulating, people in the car will feel stuffy in the chest. It is also very important to restart the external circulation and introduce fresh air outside the car.
If you feel a little cold inside the car, but you can't reach the level of heating, you can also turn on the external circulation and adjust the temperature to hot air. At this time, the air conditioning system will blow the natural wind outside the car and the hot air generated by the engine into the car, and the air conditioning fan will not turn, which is relatively energy-saving.
Of course, using this situation to raise the temperature inside the car can turn off the air conditioner in an emergency. If it is hot summer or cold winter, how should the air conditioner be turned on? Although fuel consumption will increase, don't worry too much. Air conditioning lamp is useless for heating, but it will cause unnecessary energy loss because of the operation of compressor.
Therefore, when air conditioning is used in winter in the north, it can be turned off, which has no effect on air conditioning. But it is not suitable for the cold and humid winter in the south. It is necessary to start the air conditioner to dehumidify the air, and then mix the hot air to avoid fogging the glass inside the car. Another method is to blow with cold air. Just adjust the direction of hot air to blow the front windshield, and you can easily demist in a few minutes.
