Common heating systems in automobiles can be divided into three types: coolant heating, gas heating and tail gas heating. Coolant heating is used in automobiles. It consists of cooling liquid, water pump, water valve, blower, warm air water tank (heater core) and other components. The coolant is heated by the engine and the hot water is pressurized by the water pump.
After the rotary water valve controlling the coolant flow enters the heater tank from the water inlet of the heater pipe, the coolant entering the heater tank enters the engine from the water outlet of the heater pipe, and so on. When the heater box (heater core) is heated by the coolant, the blower is also working. The blower sucks the cold air inside or outside the car, and then blows it to the heater tank.
Extended data:
The use of automobile warm air is introduced as follows:
After turning on the heating, first set the air circulation to external circulation, so that the cold air in the car can be discharged outside the car. After about 2-3 minutes, the air circulation should be set to internal circulation. In addition, the rear window is slightly opened for a period of time, because of the entry of hot air, cold air is quickly squeezed out, and the warming effect is faster.
The most comfortable temperature for human body is 20-25 degrees Celsius, so the temperature inside the car can be controlled within this range. If the hot air is not enough to reach the expected temperature at this time, the engine needs to do extra work to generate heat, and then it starts to consume oil.
Phoenix net-the correct operation of turning on the warm air in the car. After reading it, the owner regretted knowing it was late.
Phoenix. Is the com- air conditioner heater broken in winter? It turns out that they are the culprit.
