Some car owners are afraid of the cold and turn on the air conditioner to heat the car as soon as they start, thinking that this can quickly increase the temperature inside the car. In fact, this is not only ineffective, but also costly. The correct way is to start the engine for preheating first, and then turn on the heating and air conditioning after the engine temperature pointer reaches the middle position. At the same time, set the air circulation to external circulation, let the cold air in the car be discharged outside the car, wait for 2~3 minutes, and then set the air circulation to internal circulation.
In addition, some car owners asked whether to press the A/C button of the air conditioner. Actually, there is no need to press the A/C key. Everyone knows that pressing the A/C key is what we commonly call it: turning on the air conditioner. That heating belongs to the energy cycle in the car, and the heat of the cooling water tank is guided into the car, which is regarded as waste utilization.
It is worth mentioning that warm air is not suitable for blowing directly on the head. If it is blown for a long time, it will cause driver fatigue and affect driving safety. Therefore, it is suggested that under the condition of using warm air for a long time, open the window gap to let the air circulate, so as to ensure the oxygen content in the air inside the car and make the driver clear-headed. There are also some car owners who are used to resting in the car. Never turn on the heating when sleeping in the car, because it is easy to cause carbon monoxide poisoning.
