What is the function of the ECON button in Hyundai car air conditioning?

[MartinLynn]

The ECON button in the car air conditioning system is the switch for the energy-saving mode, which only takes effect when the air conditioning is set to cooling mode. 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 air conditioning power while ensuring cooling performance, thereby saving fuel. Activating the air conditioning economy mode is very simple. The driver only needs to turn on the air conditioning and press the "ECON" button to enable it. When the button light is on, the air conditioning cooling system is turned off, and only natural air or heating is provided. Here is an introduction to the ECON mode of car air conditioning: Typically, car air conditioning has an A/C indicator to show whether it is on or off, while ECON only works when the cooling mode is activated, representing the air conditioning's economy mode. In this mode, the compressor still operates, but compared to the normal mode, the control point for the compressor is higher. The compressor does not remain engaged continuously; instead, its start and stop points are controlled by the evaporation temperature. In normal mode, the compressor's start-stop range is 2~4°C. In ECON mode, the range is 8~10°C. The lower the temperature, the longer and harder the compressor works. Enabling ECON mode reduces the engine's power output, saving fuel. Functions of car air conditioning: It achieves cooling by continuously circulating refrigerant. It removes dust, odors, smoke, and toxic gases from the car's interior, freshening the air and increasing relative humidity. It uses engine coolant, waste heat, or heat generated by a burner as a heating source. The heater warms the air, which is then blown into the cabin by a fan to raise the outlet temperature for heating. It draws in fresh outside air for ventilation and air exchange, also helping to prevent windshield fogging. Precautions for using car air conditioning: Do not set the temperature too low. A large temperature difference between inside and outside the car can easily cause the driver to catch a cold, and excessively low temperatures may increase the risk of arthritis for passengers. Adjust the air vent direction. Based on the principle that cold air sinks and warm air rises, set the vents 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 prolonged sun exposure, the interior temperature will be very high. First, open the windows for ventilation, and only turn on the air conditioning after the hot air has dissipated.
