What does ECON mean in car air conditioning?

[AryaMarie]

The ECON in car air conditioning is actually a mode of the air conditioning system, which only takes effect when the air conditioning's cooling function is turned on. The air conditioning compressor is driven by the engine and can consume up to 20% of the engine's power. When the ECON mode is activated, the vehicle reduces the power consumption of the air conditioning while maintaining its cooling effect, thereby saving fuel. 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 cooling system of the air conditioning is turned off, and only natural wind or warm air is provided. The introduction to the ECON mode of car air conditioning is as follows: Usually, the car air conditioning has an A/C symbol to indicate whether the air conditioning is turned on or off, while ECON only takes effect when the cooling function is turned on, representing the economy mode of the air conditioning. In this state, the compressor also works. Compared to the normal mode, the control point of the compressor is increased, and the compressor does not continuously engage during operation. The start and stop points of the compressor are controlled by the evaporation temperature. In normal mode, the start and stop points of the compressor are 2~4°C. In ECON mode, the start and stop points of the compressor are 8~10°C. The lower the temperature, the longer the working time and the greater the workload of the compressor. After turning on the ECON mode, it saves the engine's power output and fuel. The functions of car air conditioning: Achieve cooling effect through the continuous cycle of refrigerant; Remove dust, odors, smoke, and toxic gases from the car's air to make the air inside the car fresh, and humidify the air inside the car to increase the relative humidity of the air inside the car; Use the engine coolant, waste heat, or heat generated by a burner as a heat source for heating, which is heated by the heater and sent into the car's air or outside air by the blower to increase the temperature of the air outlet for heating purposes; Draw in fresh air from outside for ventilation and air exchange, which also plays a good role in preventing window 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 too low a temperature may also increase the risk of arthritis for passengers in the car. Control the direction of the air outlet. Based on the principle that cold air sinks and hot air rises, when controlling the air outlet of the air conditioning, you can follow the rule of directing the air outlet 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 the car has been 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 discharged.
