What does ECON on car air conditioning mean?

[LukasAnn]

ECON on car air conditioning is actually an energy-saving mode of the air conditioning system, which only takes effect when the air conditioning's cooling function is activated. The air conditioning compressor is driven by the engine and can consume up to 20% of the engine's power. After activating the ECON mode, the vehicle will reduce the air conditioning's power while ensuring its cooling effect, thereby achieving fuel savings. The method to turn on the air conditioning's economy mode is very simple. The owner just needs to press the "Econ" button after turning on the air conditioning. When the light on the button is on, the air conditioning's cooling system is turned off, and only natural air or warm air is provided. Here is an introduction to the ECON mode of car air conditioning: Usually, the A/C symbol on car air conditioning represents the on/off state of the air conditioning, while ECON only takes effect when the cooling function is activated, representing the air conditioning's economy mode. In this state, the compressor will also work. Compared to the normal mode, the control point of the compressor is increased, and the compressor does not remain engaged continuously during operation. The start and stop points of the compressor are controlled by the evaporation temperature. In normal mode, the compressor's start-stop point is 2~4°C. In ECON mode, the compressor's start-stop point is 8~10°C. The lower the temperature, the longer the compressor's working time and the greater its workload. Activating the ECON mode will save engine power output and fuel consumption. The functions of car air conditioning: Achieve cooling effects through the continuous cycle of refrigerant state changes; Remove dust, odors, smoke, and toxic gases from the car's interior air to freshen it, and humidify the interior air to increase its relative humidity; Use the engine coolant, waste heat, or heat generated by a burner as a heat source for heating. The heater heats the air, which is then blown into the car by the blower to raise the temperature at the air outlets for heating purposes; Draw in fresh external air for ventilation and air exchange, which also helps prevent windshield fogging. Precautions for using air conditioning in the car: Do not set the air conditioning temperature too low. A large temperature difference between the inside and outside of the car can easily cause the driver to catch a cold, and excessively low temperatures may also pose a risk of arthritis for passengers. Control the direction of the air outlets. Based on the principle that cold air sinks and hot air rises, when using the air conditioning, set the air outlets upward when cooling and downward when heating. Do not turn on the air conditioning immediately after the car has been exposed to the sun. After being exposed to the sun, the temperature inside the car will be very high. First, open the windows for ventilation, and then turn on the air conditioning after the hot air has been expelled.
