[How to turn on the car heating air conditioner] Does the car heating air conditioner consume fuel in winter? The precautions for the car heating air conditioner
Does the heating and air-conditioning consume fuel in winter?
Turning on the air-conditioning will increase fuel consumption, almost everyone thinks so. A friend of mine thought so. In order to save fuel, he wore thick winter clothes without turning on the heater. Indeed, turning on the air conditioner in summer will definitely increase fuel consumption. But the warm air in winter is another matter. It uses the heat generated by the engine and transfers it to the cab through the blower, which belongs to heat reuse. Therefore, the power consumption of the warm air is much lower than that of the cold air conditioner, and the fuel consumption is negligible. . Let’s take a look at the correct way to open it with warm air in winter.
1, do not turn on the heater immediately after the car is started
do not turn on the heating and air conditioning immediately when the car is hot, be sure to Wait until the water temperature of the engine water tank rises before turning on the heater. When the car is just started, it takes a certain amount of time for the oil to lubricate the various parts. Especially in winter, when the temperature is low, the warm-up time will be longer. Turn on the heater when the car is cold, the engine temperature has not risen yet, and the wind blowing out is also cold. The correct way is to wait 3-5 minutes after the car is started, and then turn on the heater after the water temperature rises.
2, the windows are fogged, and the heater wind speed should be increased
For fogging, most people turn off the warm air or use cold air to drive the fog, which will cause repeated fogging and increase fuel consumption. The correct way is to increase the wind speed of the warm air and blow it for a while, so that the fog disappears and does not appear repeatedly.
3, don’t openA/Cbutton
The A/C button is the switch of the air conditioner compressor. Turning it on for cooling will of course increase the fuel consumption. The cold air and the warm air in the car are two systems. The warm air is generated by the heat cycle of the car itself and does not need a compressor to work.
4, The circulation mode is set to internal circulation
Set the air conditioning circulation mode to In the internal circulation mode, the temperature inside the car will rise rapidly. After the car feels warm, switch to external circulation, which will help the air flow in the car. After a long drive, you need to take a breath after a period of time. The air in the confined space is not smooth, and the people in the car will not breathe well for a long time. The method is to roll down the window and make a small crack.
5. Adjust the appropriate temperature
The temperature of the air conditioner should not be set too high, generally not higher than 23 degrees Celsius, the temperature will make you sleepy for a long time affect driving. In addition, don’t let the warm air blow directly on your face, it is easy to cause fatigue, affect driving safety, and the skin on your face is easy to dry. Adjust the wind direction to blow on the legs and feet, and the whole body will be warm when the legs and feet are warm.
In this way, you can use the warm air to your heart’s content when driving in winter. However, there is one thing you must know: you can’t sleep in the car with the heater on! Because it is easy to be poisoned by carbon monoxide!
Precautions for car heating and air conditioning
1. First of all, it is necessary to understand the working principle of the car heater, which does not require other equipment on the car It can work, just waste utilization of car heat, rather than compressor work like air conditioner.
2. But there is one thing to pay attention to, that is, when the heater is turned on, do not click the A/C button of the air conditioner. In that case, the compressor will be activated, which will consume more fuel.
3. Before turning on the heater, wait until the car is warmed up before turning it on, that is, wait until the equipment in the car has hot air circulation before turning it on. First open the outer loop for 5 minutes, and then switch to the inner loop.
4. After the air conditioner is turned on in the car, there are a few things that people in the car should pay attention to. First of all, don’t sleep with the heater on after the car is parked, it is easy to be poisoned by carbon monoxide!
5. Another one is not to smoke. If you smoke, it will cause air pollution to all passengers in the car, and also make the air conditioner filter suffer and reduce the name!
6. Another little trick for heating is to adjust the wind direction to blow the glass directly when there is fog in the windshield before winter, and the fog can be dissipated in three minutes!
