A Right Way to Use Bus Air Conditioner

Summer is coming and the whether is becoming hotter and hotter. So we would use bus air conditioners more frequent.

Today we would show you the right way to use bus air conditioner in summer. 

Below is the detail steps:

1. Don’t turn on the air conditioner when the bus just starts

Because the whether is hot and inside the temperature is high. So you may turn on the air conditioner at first. But this is not good.
a. By this way, the cooling effect is not very obvious.
b. This would increase the engine’s load at first and increase fuel consumption.

Right way: First open all the windows for a while, 5-10 minutes, and then turn on the air conditioner would be netter.

2. Don’t choose the lowest temperature.

For most drivers, they all hope to cool the temperature quickly, so they set the lowest temperature. In this way, the temperature difference is big and the engine need greater power and higher speed to maintain the air conditioner work, which would increase the fuel consumption.

Right way: Normally, the temperature difference between the body and ambient should be 5??6?, and could be bigger at noon. The driver should check the ambient temperature when set the bus air conditioner’s temperature. This is also a way to protect air conditioners and extend service life.

3. Air conditioner should not be in low-grade all the time

If the air conditioner works at low-grade for a long time, in the air diffuser would accumulate lots of dust, which would have bad influence on the people’s health. So we should switch different grade regularly, thus would blow out the dust.

Right way: Every once in a while, we should turn the air conditioner to highest gear and works for half an hour.

4. The cooling system should work normally when meeting the three requirements at the same time:
a. Engine is in idling.
b. The temperature should be 5?
c. A\C switch should be in some gear.
