What does the ECON mode in car air conditioning mean?

The ECON mode in car air conditioning is actually an energy-saving mode of the air conditioning system. The ECON mode only takes effect when the air conditioning is turned on for cooling. 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 will reduce the power consumption of the air conditioning while ensuring its cooling effect, thereby saving fuel. The method to activate the air conditioning's economy mode is very simple. The owner only needs to turn on the air conditioning and press the "ECON" button to activate it. When the light on the button is on, the air conditioning cooling system is turned off, and only natural or warm air is used. Here is an introduction to the car air conditioning ECON mode: Usually, the car air conditioning has an A/C symbol to indicate whether the air conditioning is turned on or off, while ECON only works when the air conditioning is turned on for cooling, representing the economy mode of the air conditioning. 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-stop point is 2~4℃. In ECON mode, the compressor's start-stop point is 8~10℃. The lower the temperature, the longer the compressor's working time and the greater the workload. Activating the ECON mode will save the engine's power output and save fuel. The functions of the car air conditioning: Using the continuous phase change cycle of the refrigerant to achieve the cooling effect; Removing dust, odors, smoke, and toxic gases from the air inside the car to freshen the air, and humidifying the air inside the car to increase the relative humidity; Using the engine coolant, waste heat, or the heat generated by a burner as a heat source for heating, which is heated by the heater and sent into the car or outside air by the blower to increase the temperature at the air outlet for heating purposes; Drawing in fresh air from outside for ventilation and air exchange, which also plays a good role in preventing windshield fogging. Precautions for using the 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 too low a temperature may also pose a risk of arthritis for the 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 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 temperature inside will be very high. First, open the windows for ventilation, and then turn on the air conditioning after the hot air has been discharged.
As a veteran driver who frequently takes long-distance trips, I've studied the air conditioning functions thoroughly. The ECON button stands for economy mode. When activated, the air conditioning compressor reduces its operating intensity or frequency, primarily to save fuel. In urban traffic congestion or on cool weather days, I often use ECON because it significantly reduces fuel consumption, saving me a considerable amount on gas each month. However, I avoid using it during high summer temperatures as it weakens the cooling effect, making the car feel stuffy and affecting driving comfort. Additionally, long-term use of ECON mode helps reduce engine load, potentially extending the air conditioning system's lifespan and minimizing maintenance needs. I find this feature very practical, but it's important to adjust its use flexibly based on actual conditions, not blindly pursuing fuel savings at the expense of comfort. Overall, it's a smart energy-saving tool that's worth understanding for car owners.
As a commuter who pinches pennies on fuel costs, the ECON button is my favorite AC setting. It stands for 'economy' mode, which means the AC cooling isn't as aggressive, reducing compressor workload and directly lowering fuel consumption. I keep it on during highway drives or in spring/autumn, significantly improving fuel efficiency and cutting annual expenses. Though cooling isn't as intense, it maintains decent comfort unless temperatures are extreme. I've also noticed quieter AC operation in ECON mode, enhancing cabin tranquility. Highly recommend trying it for daily driving—especially with rising fuel prices—it's wallet-friendly and eco-conscious. Just avoid over-reliance during scorching days; balance is key.
