What does ECON on a car air conditioner mean?

[LaEthan]

The ECON on a car air conditioner is actually an energy-saving mode of the air conditioner, which only takes effect when the air conditioner's cooling function is activated. 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 power consumption of the air conditioner while ensuring its cooling effect, thereby achieving fuel savings. The method to activate 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 to the car air conditioner's ECON mode is as follows: Usually, the car air conditioner has the "A/C" symbol to indicate whether the air conditioner is on or off, while ECON only takes effect when the air conditioner's cooling function is activated, 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 does not continuously engage during operation. The start and stop points of the compressor are controlled by the evaporation temperature. In normal mode, the compressor's start and stop points are 2~4°C. In ECON mode, the compressor's start and stop points are 8~10°C. The lower the temperature, the longer and harder the compressor will work. Activating the ECON mode will save the engine's power output and save fuel. The functions of the car air conditioner: Achieve cooling effects by continuously changing the state of the refrigerant in a cycle; Remove dust, odors, smoke, and toxic gases from the air inside the car, making the air fresher, and humidify the air inside the car to increase its relative humidity; Use the engine coolant, waste heat, or heat generated by a burner as a heat source for heating, and heat it through a heater, then blow the heated air into the car or outside air to raise the temperature at the air outlet for heating purposes; Draw in fresh air from outside 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 the occupants. Control the direction of the air outlet. Based on the principle that cold air sinks and hot air rises, when controlling the air conditioner's air outlet, you can follow the rule of pointing 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 for ventilation, and then turn on the air conditioner after the hot air has been expelled.
