Why is there no hot air in the car?
1 Answers
The reasons why the car has no hot air: 1. The engine thermostat fails; 2. The hot water valve or the vacuum driver of the hot water valve fails; 3. The heater inlet and outlet pipes are blocked or the heater core is clogged with dirt; 4. The temperature control damper or the control cable is damaged; 5. The air conditioner blower is damaged or the blower control circuit fails; 6. The air conditioner air distribution pipeline is blocked or leaks. The heat sources used by car heating equipment are divided into non-independent heating systems and independent heating systems. Non-independent heating systems use the waste heat of car exhaust or the waste heat of the engine cooling circulation as the heat source and introduce it into the heat exchanger. The fan blows the air inside or outside the car through the heat exchanger to heat it up. Independent heating systems are generally composed of a combustion chamber, a heat exchanger, a fuel supply system, an air supply system, and a control system.
