What does ECON mean in a car?

[McMatthew]

The ECON in a car's air conditioning system is actually an energy-saving mode, 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 reduces the air conditioning's power while ensuring its performance, thereby achieving fuel-saving effects. The method to turn on the air conditioning's economy mode is very simple. The owner only needs to press the "ECON" button after turning on the air conditioning. When the button's light is on, the air conditioning's cooling system is turned off, and only natural or warm air is provided. The introduction to the car air conditioning's ECON mode is as follows: Usually, the car air conditioning has an "A/C" indicator to represent the air conditioning's on or off status, while ECON only takes effect when the air conditioning's cooling function is activated, representing the air conditioning's economy mode. In this state, the compressor also works. Compared to the normal mode, the compressor's control point is raised, and it does not remain continuously 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 and more intensive the compressor's operation will be. Activating the ECON mode saves the engine's power output and conserves fuel. The functions of the car's air conditioning: Using the continuous phase change cycle of the refrigerant to achieve cooling effects; Removing dust, odors, smoke, and toxic gases from the car's interior air, making the air inside the car fresher, and humidifying the car's interior air to increase its relative humidity; Using the engine's coolant, waste heat, or heat generated by a burner as a heat source for heating, which is then heated by the heater and blown into the car's interior or exterior air by the blower, raising the temperature at the air outlet to achieve heating purposes; Drawing 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 outlet. Based on the principle that cold air sinks and hot air rises, when controlling the air conditioning's air outlet, you can follow the rule of pointing the 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 interior temperature can be very high. First, open the windows for ventilation, and only turn on the air conditioning after the hot air has been expelled.
