Why does the home air conditioner not produce hot air?
When this happens, it may be that the heater water tank is faulty, or the water valve of the heater water tank is faulty. When this happens, check the heater water tank and heater water valve. Car air conditioners use engine heat for heating.
When the car air conditioner is heating, the high-temperature coolant in the engine will flow through the heater water tank. At this time, the wind blown by the blower will also pass through the heater water tank, so that the car air conditioner air outlet can blow out warm air. .
The heater water tank of the car air conditioner is a heat exchanger. Without this component, the car air conditioner cannot heat.
If the heater water tank or heater water valve fails, the car air conditioner will not be able to heat.
If the engine has just been started, the air conditioner will not be able to heat.
The temperature of the engine is relatively low when it first starts, and the temperature of the coolant is relatively low at this time, so when the air conditioner is turned on, all the cold air blows out.
It is recommended that when using the car in winter, turn on the heating function of the air conditioner after 10 to 20 minutes of normal driving.
If the heating function is turned on when the engine temperature is low, it will cause the engine to heat up slower, which will affect the engine's fuel consumption and power.
The lower the engine temperature is, the better. The engine has a normal operating temperature range.
Only when the engine temperature is in this range, the engine power is the best, and the fuel economy is also the best.
