What does ECON mean on a car air conditioner?

[McAdeline]

The ECON on a car air conditioner is actually an energy-saving mode of the air conditioner. ECON only takes effect when the air conditioner's cooling function is turned on. The air conditioner 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 conditioner's power while ensuring its cooling effect, thereby saving fuel. The method to turn on the air conditioner's economy mode is very simple. The owner only needs to press the "ECON" button after turning on the air conditioner. When the light on the button is on, the air conditioner's cooling system is turned off, and only natural air or warm air is provided. The introduction of the car air conditioner's ECON mode is as follows: Usually, the A/C symbol on a car air conditioner represents the air conditioner being turned on or off, while ECON only takes effect when the air conditioner's cooling function is turned on, representing the air conditioner'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 is not always engaged 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. After activating the ECON mode, the engine's power output is saved, and fuel is conserved. The functions of the car air conditioner: Achieve cooling effects through the continuous cycle of refrigerant; Remove dust, odors, smoke, and toxic gases from the car's air, making the air inside the car fresher, and humidify the car's air to increase its relative humidity; Use the engine's coolant, waste heat, or heat generated by a burner as a heat source for heating. The heater warms the air, which is then blown into the car by the blower, raising the temperature at the air outlet to achieve heating; Draw fresh air from outside the car for ventilation and air exchange, which also helps prevent window fogging. Precautions for using the air conditioner in the car: Do not set the air conditioner 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 to passengers. Control the direction of the air outlet. Based on the principle that cold air sinks and hot air rises, when using the air conditioner, set the air outlet upward when cooling and downward when heating. Do not turn on the air conditioner immediately after the car has been exposed to the sun. After the car has been exposed to the sun, the temperature inside will be very high. First, open the windows to ventilate and let the hot air out before turning on the air conditioner.
