Should the Car Air Conditioning Be Set to Recirculate Mode When Cooling?
1 Answers
Car air conditioning should be set to recirculate mode when cooling. Below are the relevant explanations: Reasons: In some areas, PM2.5 pollution is severe on certain days, with PM2.5 levels above 50. Unless the air quality is good, it is recommended to use recirculate mode to avoid inhaling excessive PM2.5 particles. During summer when the air conditioning is on, it is advisable to use recirculate mode because using fresh air mode allows hot outdoor air to enter the car, forcing the air conditioning to work continuously in cooling mode with poor cooling efficiency. Car Air Conditioning: The car air conditioning system, abbreviated as car AC, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to optimal conditions. It provides a comfortable environment for passengers, reducing travel fatigue, and creates good working conditions for the driver, playing a crucial role in ensuring safe driving as a ventilation device.
