What does ECON mean?

[DiLaila]

The ECON mode in car air conditioning is actually an operating mode of the air conditioning system. ECON only takes effect when the air conditioning cooling is turned on. Since the air conditioning compressor is driven by the engine and can consume up to 20% of the engine's power, enabling ECON mode will reduce the air conditioning power while maintaining cooling performance, thereby achieving fuel-saving effects. The method to activate the air conditioning economy mode is very simple: after turning on the air conditioning, the driver just needs to press the "ECON" button. When the button light illuminates, the cooling system turns off while natural air or heating continues operating. Introduction about car air conditioning ECON mode: Normally, the A/C indicator in cars represents air conditioning on/off status, while ECON only functions when cooling is activated, indicating the economic mode of air conditioning. In this mode, the compressor still operates but with adjusted parameters. Compared to normal mode, the compressor's control point increases, and it doesn't remain constantly engaged. The compressor's start/stop points are controlled by evaporation temperature. In normal mode, the compressor activates at 2~4°C. Under ECON mode, this range increases to 8~10°C. Lower temperatures require longer compressor operation time and workload. Enabling ECON mode saves engine power output and reduces fuel consumption. Functions of car air conditioning: Achieves cooling effect through continuous refrigerant cycle; Removes dust, odors, smoke and toxic gases from cabin air, improving air quality while humidifying to increase relative humidity; Utilizes engine coolant, waste heat or burner-generated heat as warming source. After heater processing, air is blown into cabin by blower to raise outlet temperature for heating purposes; Introduces external fresh air for ventilation, which also effectively prevents windshield fogging. Precautions for using car air conditioning: Avoid excessively low temperature settings. Large indoor-outdoor temperature differences may cause driver colds, while extreme cold could lead to arthritis risks for passengers. Adjust air vent direction. Following the principle that cold air sinks and warm air rises: set vents upward when cooling and downward when heating. Don't immediately turn on AC after sun exposure. When the car has been parked under strong sunlight, first open windows for ventilation before activating air conditioning after heat dissipation.
