How to turn on the Chevrolet heater: 1. Start the engine; 2. Press the air conditioner (A/C) button (the prompt light is on to confirm the operation of the air conditioner); 3. Adjust the speed of the fan, especially when the fan control knob is in the closed position, the air conditioner cannot run. It is easy to adjust the warm air with an empty car. Just raise the temperature, and then choose the appropriate air volume. When using the air conditioner heater, you don't need to press the air conditioner button. This is the air conditioning switch of the car. The heating principle of an empty car is very simple. When heating, the high-temperature antifreeze in the engine will pass through the warm water storage tank, and the wind blown by the blower may also pass through the warm water storage tank, so that the air outlet can be adjusted to blow out warm air. The refrigeration principle of an empty car is also very simple. When cooling, the engine will drive the compressor to rotate. At this time, the compressor can continuously compress the refrigerant and transport it to the evaporation box. The refrigerant expands and absorbs heat in the evaporation box, so that the refrigerant cools the evaporation box, and the cooled evaporation box cools the air blown by the fan, so that the air outlet of the air conditioner blows cold air.
