How to Turn on the Car Air Conditioning in Cold Weather?
1 Answers
Here are the methods for using car air conditioning in winter: 1. Do not turn on the heater immediately after starting the car. In winter, the engine coolant temperature is very low when the car is just started. Turning on the air conditioning at this time not only increases the engine load but also results in insignificant temperature rise, so do not rush. The correct method is to start the car and warm it up while driving. Wait until the coolant temperature gauge pointer reaches the middle position before turning on the heater. Set the air circulation to external circulation to expel the cold air inside the car, then switch to internal circulation after 3 minutes. 2. Turn off the A/C when using the heater in winter. The A/C in a car can be understood as the air conditioning cooling switch. When the A/C light is on, it means the air conditioning compressor is activated, increasing engine load and fuel consumption. The heating principle of the heater utilizes the heat generated by the engine itself, which is delivered into the car through the air conditioning ducts without the involvement of the compressor. Therefore, turning on the A/C in winter does not enhance the heating power of the heater but instead wastes the compressor's effort unnecessarily.
