The principle of warm air tank is:
1. In addition to a radiator in the engine compartment, there is also a heat exchanger in the dashboard of the cab, and the antifreeze used to dissipate heat in the engine flows in the middle. ?
2, improve heat dissipation: opening the warm air can improve the heat dissipation in the car, which is especially useful for some Jetta cars to run long distances. ?
The HFJ635 1B car is equipped with a water heating heater. The cooling water of the engine is used as the working medium and blown into the car from the same air outlet under the action of a blower, so as to achieve the purposes of heating, ventilation and defrosting.
There are two main air intake methods: one is indoor air circulation, and the other is outdoor fresh air entering the car for ventilation circulation. The blower is electrically driven and influenced by the engine speed, so it can still be used for heating and defrosting even if the engine speed is very low.
Extended data:
The advantages of heater heating are:
1, the heat supply of a single machine is large, and the number of terminal equipment used under the same heat load is small;
2. The small heater can be hung, which does not occupy the building area, and the large heater is installed on the floor, which covers a limited area;
3, the start-up temperature is fast.
The disadvantages of heater heating are:
1, the fan is noisy when the heater is running. Generally, the noise of small heaters is about 60dB(A), and the noise of large heaters is even greater.
2. The heater is placed in the heating room to directly heat the indoor circulating air without supplementing fresh air (outdoor air), which cannot improve the indoor air quality.
In view of the advantages and disadvantages of heater heating, the heater heating system is suitable for the following situations:
1, large space, large heating load, so that indoor air can be recycled;
2, factories, workshops, venues and other places that need to quickly raise the room temperature;
3. Some non-three-shift workshops have intermittent heating.
