What are the steps to turn on the air conditioner in summer?

It is usually very hot in summer. Before getting on the bus, if your car is parked outdoors and exposed to the sun, please turn on the air conditioner immediately before getting on the bus, because the temperature inside the car will slowly drop, which will cause great waste. If possible, you can open all the doors first, then open the external circulation of the air conditioner and adjust the air volume to the maximum. Be careful not to turn on the air conditioner switch. Let the air conditioner use natural wind to move the turbid air in the train. After 2-3 minutes, turn on the air conditioner switch for refrigeration, turn on the internal circulation and close the window. This will make the air conditioning refrigeration effect better and save fuel. Secondly, the choice of air outlet is also helpful for air conditioning and refrigeration. Because of the principle of air convection, hot air goes up and cold air goes down. Then point the air outlet of the air conditioner obliquely upward, and make use of the law that hot air rises and cold air falls, so that the car can quickly cool down in the process of cold air falling. At the same time, be careful not to place decorations in front of the air outlet of the air conditioner, which will affect the refrigeration effect of the air conditioner. It is worth noting that turning on the automobile air conditioner will affect the automobile fuel consumption. Although the cold wind with large air volume makes you comfortable to blow in the car, the fuel consumption of the car will also make you feel distressed, and the power of the car with small displacement may be weakened. Therefore, the car mainly uses air conditioning and refrigeration reasonably. A few minutes before driving, the temperature can be lowered to improve the refrigeration efficiency, and after a period of time, it can be raised by several degrees. Or turn off the air conditioner later and let the air conditioner have a rest. After all, using air conditioner for a long time will increase the pressure of condenser and cause losses to refrigeration system. In short, starting refrigeration as soon as you get on the bus will cause waste on the one hand and damage the refrigeration system on the other.
