Does the AC button need to be turned on when the car heater is turned on?
When using car heaters, many car owners have doubts about whether they need to turn on the AC key. In fact, you don't need to turn on the AC key when turning on the heater. The English of the AC key is air conditioning, that is, air conditioning conditioning. When turning on the air conditioner in summer, you need to turn on the AC button to start the compressor to achieve the effect of refrigeration. In winter, when the heater is turned on, the compressor does not work, and the heater is to transfer the heat generated by the engine to the car, so there is no need to turn on the AC button.
How car heaters work
The heating system of the car is mainly achieved through the circulation of engine coolant. When the engine is running, a large amount of heat is generated, and the coolant circulates inside the engine, absorbing and carrying away this heat. When the heater switch is turned on, the coolant flows through a heat exchanger called the heater core, releasing heat into the air inside the car, providing warm air.
How to use car heaters correctly
Start the engine to warm up: Before turning on the heater, it is recommended to start the engine to warm up and let the coolant circulate, which can provide warm air more quickly and reduce the load on the engine.
Adjust the temperature and air volume: Adjust the temperature and air volume of the warm air through the control panel according to individual needs. In general, the temperature can be set within a suitable range and avoid being too high or too low.
Use the Inner Cycle Mode: When the temperature inside the car is low, you can use the Inner Cycle mode, which can increase the temperature in the car more quickly. When the temperature in the car reaches a suitable level, you can switch to the external circulation mode to keep the air in the car fresh.
Pay attention to safe use: When using warm air, make sure that it does not affect driving safety. Avoid fatigue or drowsiness caused by prolonged use of heaters, and open windows for ventilation in time to maintain air circulation.
When to use the AC key
The AC key is mainly used in refrigeration mode. When using the air conditioner in the summer, you need to turn on the AC key to start the compressor for cooling. When the temperature in the car reaches the set value, the compressor will automatically stop working, and the AC button can be turned off to save energy consumption. It should be noted that using the AC key in refrigeration mode will increase the load and fuel consumption of the engine.
