When we icing Snow or cold environment，I am still warm in the car.，This is due to the automobile heating system。Bring the car heater，Maybe everyone is not stranger，Because everyone can use it，However, many people don't understand the mode of operation of this system.。In addition，What if the warm air is not hot?？
If you are divided by heat source type，There are two main types of automobile heating systems.：One is the use of engine coolant as a heat source（At present, most vehicles are in use.）；Another use of fuel as a heat source（Some high-end cars are used）。In order to let everyone know what the car heating 易彤破壁机哪里可以维修 system is happening？Below we will briefly introduce the mainstream automobile heating system，The system uses engine coolant as the currently widely used heat source。
The principle of the car heater：
When the engine coolant temperature is high，Coolant flows through the heat exchanger in the heating system（Usually referred to as small water tank），The air delivered by the blower is heat exchange with the engine cooling liquid.，After the air is heated It is sent from the blower through each air outlet。This system is simple and reliable，No additional fuel，As long as the engine is running，Will produce hot water。But it also has obvious shortcomings，That is， When the engine coolant temperature rises to a large cycle，Heating must be performed。
Steps to open warm air：
1。Car is started，about8Until15After 易彤破壁机维修点 a minute，Water temperature rises to normal temperature can open the warm air。（That is when the water temperature rises to the middle）
2。Adjust the air conditioner loop to the vehicle cycle
3。Switch to warm air mode，Some cars in the red area，Some cars are represented by the sun
4。Do not open air conditioners（Do not open the AC switch），Because hot air uses the thermal cycle of the car itself，Energy saving！
5，Gears suitable for air conditioning gears，Adjust the wind direction。The direction of the warm wind is usually downward and at the foot。Cold winds usually blow forward。
What if the hot air is not hot?？
The heating system of the car has not been used for a long time.，Many faults will inevitably。Owner，You can perform the following steps first：
1。Check the cold and cold of the windshield，Check if the air conditioner has been adjusted to the hot windshield；
2。Check the electronic fan temperature control switch；
3。Check water temperature regulator。
Generally，There are two reasons why the vehicle heating system is not hot.：One is caused by the engine cooling system，First, due to the adverse work of the heating control mechanism。For ordinary owners，Some difficulties in these issues。Some maintenance is more complicated，Still 易彤料理机修理 hire professional。
