How to turn on hot air in your car: A guide to using warm air in winter
As the temperature drops sharply in winter, how to correctly use the heater in the car has become a hot topic for car owners. This article will combine hot topics and common user questions in the past 10 days on the Internet to provide you with a detailed analysis of how to use car heaters, precautions and solutions to common problems.
1. Working principle of car heater
The car heater system uses the heat of the engine coolant to send hot air into the car through the heater tank and blower. Unlike air conditioning and refrigeration, heating does not increase fuel consumption (except for electric vehicles).
| system components | Function description |
|---|---|
| Heater water tank | The radiator through which engine coolant flows |
| Blower | Push air through heater tank |
| temperature control valve | Adjust coolant flow |
| Air duct distribution system | Control the air outlet direction |
2. Steps to correctly turn on the heater
| steps | Operating Instructions | Things to note |
|---|---|---|
| 1 | Start the vehicle and wait for the water temperature to rise to the normal range (about 60°C or above) | Turning on the heater immediately when the car is cold will increase the load on the engine |
| 2 | Turn off the AC switch (unless defogging is required) | Warm air does not require compressor operation |
| 3 | Adjust the temperature knob to the red zone | Generally, 25-28℃ is the comfort zone |
| 4 | Choose the appropriate air volume level | It is recommended to start with a low gear and then gradually increase it. |
| 5 | Adjust the direction of the air outlet | Recommend blowing feet downward + front windshield |
3. Solutions to common problems
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| The wind is not hot | Insufficient coolant/blocked heater water tank | Check coolant level, professional cleaning |
| There is a peculiar smell | Mildew in air conditioning pipes | Replace the air conditioning filter element and clean the air duct |
| Small air volume | Blower failure/filter clogged | Check the circuit and replace the filter element |
| Car windows fog up | Large temperature difference between inside and outside, high humidity | Turn on AC + external circulation dehumidification |
4. Differences in the use of heaters in new energy vehicles
Since electric vehicles have no engine waste heat, they need to be heated by a PTC heater or heat pump system, which will significantly affect the cruising range. Suggestions:
1. Prioritize the use of local heating such as seat heating/steering wheel heating
2. Proper preheating (turn on the heater when charging)
3. Keep the battery at a suitable temperature (low temperatures will reduce heating efficiency)
5. Tips for saving fuel/electricity
| Skills | Traditional fuel vehicle | New energy vehicles |
|---|---|---|
| optimal temperature | 22-25℃ | 20-22℃ (each 1℃ increase reduces battery life by 5%) |
| cycle mode | Internal circulation after temperature stabilization | Intermittent use of external circulation to prevent glass fogging |
| Auxiliary equipment | Steering wheel cover reduces heat loss | Use the scheduled heating function |
6. Misunderstandings about using warm air in winter
1.Misunderstanding:Turn on maximum heating as soon as it starts →Facts:Will prolong the engine warm-up time
2.Misunderstanding:Long-term open internal circulation →Facts:Easy to cause hypoxia and glass fogging
3.Misunderstanding:Heating consumes oil →Facts:The heater of fuel vehicles basically does not increase fuel consumption (except electric vehicles)
4.Misunderstanding:The higher the temperature the better →Facts:Excessively high temperatures may cause dryness and discomfort
With the above structured guide, I believe you have mastered the correct use of vehicle heaters. When driving in winter, you must not only ensure comfort, but also pay attention to driving safety. It is recommended to check the cooling system regularly and keep the air conditioning pipes clean to keep your car warm during the winter.
