What are the heating methods of cars on the market? Which heating method is the best?

We need to pay attention when using the car heater, because our car heater comes from the heat generated by engine combustion, so we need to pay attention to that when our car engine has no temperature, our air conditioner heater will not have temperature. The warm air tank is connected to the cooling system, just like a radiator. High-temperature coolant circulates internally, and air flows out from the outside of the warm air tank to be heated. This is why the warm air will be hot after the engine water temperature comes up. The warm air of the car comes from the heat emitted by the engine cylinder. A radiator should be added to the radiator pipe, which is equivalent to connecting a group of radiators in parallel when heating at home, and blowing geothermal air near the radiator into the car through a fan.

The principles of car heating and air conditioning are different. The cold air is cooled by the air-conditioning compressor, which needs to be driven by the engine, so the fuel consumption per 100 kilometers will increase by about1L. How to use warm air in winter? Start the internal combustion engine and try to see if there is hot air when the temperature of the internal combustion engine rises. At this time, the small circulation of warm air is used for heating, and the heat is small. When the coolant temperature tends to be normal, the thermostat opens and the large and small cycles work at the same time. When driving a vehicle for a long time, use more external circulation and less internal circulation. Otherwise, there are too many people in the car, and driving for a long time will lead to low oxygen content in the car, and driving for a long time will cause a groggy feeling.

Air heating, as its name implies, is to keep warm through the waste heat of automobile exhaust. As we all know, automobile exhaust will take away a lot of heat, so it is a way to use waste resources. Turn on the fan switch, the cold air will be warmed after heat exchange through the warm air trough under the action of the fan, and the warmed air will be sent to the air outlet through the air duct to be blown out. At this time, we feel very warm inside the car when driving. The advantage of heating with engine cooling water is that it costs no oil or electricity (except for blower), as long as the engine water temperature is relatively stable after normal. But the disadvantage is that there is no heating when the car is cold, especially in extremely cold areas.
