Common Faults of Van air conditioning system:
1. The electromagnetic clutch is not combined due to the failure of the pressure switch and the compressor does not work.

2. Lack of refrigerant and insufficient system pressure.

3. The condenser is too dirty, which affects the heat dissipation of the high-pressure gaseous refrigerant.

4. The cooling capacity is large during high-speed driving, and the evaporator is frosted, but this is rare. There is no wind in the rooftop van air conditioner when this kind of failure occurs.

These troubleshooting require special tools except for the dirty third condenser. Therefore, it is best to go to a professional repair shop for this type of failure, which is difficult to solve by yourself.

Then there is the poor air conditioning effect caused by the van itself:
1. The power of the van engine is generally not very high, so the ...
... power of the supporting compressor is also small, otherwise it will seriously occupy the engine power and affect the driving experience. When the compressor power is small, the cooling capacity is small when the engine is at low speed. Generally, the air conditioner feels "not so hot" when the van is idling. If you want to achieve the feeling of "cold", you must increase the speed.

2. The van has a large space, simple interior, and heat insulation capacity is not as good as that of a car.

3. Many vans have mid-mounted engines. The engine is under the driver's seat. This is an awkward position. Not to mention the grilled butt, the airflow during driving is not easy to blow to the engine, so the heat generated by the engine is difficult to dissipate and continue to give The cockpit is heated and will enter the cockpit through the handbrake gap. The car engine is in the front of the car, and the airflow directly blows into the engine compartment during driving, which can take away more heat.

How to deal with these problems:
1. For the problem of low compressor power, we can choose to increase the engine speed to solve it. Like Wuling Rongguang, the power of the 1.2 engine is very obvious after the air conditioner is turned on. At this time, it can be reduced by one gear when driving at low speed, so that the engine has more power, the air conditioner is cooler, and the power is better. Of course, it is only possible to operate in this way at medium and low speeds. After the speed of the car is running, the engine speed is increased and the power is enough. At this time, you can drive in the normal gear.

2. Vans are generally bought as tool carts. Most of the time they are driven by one person. At this time, you can buy a curtain to isolate the cockpit from the rear of the car. This effect is the best.

3. The engine’s grilling butt is hard, but there are also solutions. You can buy some double-sided foam tape, which is very thick. Open the driver's seat, paste a circle on the red dot in the picture above, and then remove the back and use a small amount. The oil is applied to make the glue lose its viscosity, so as not to stick to the seat, so that the soft foam can fully fill the gap between the seat and the engine compartment and block the heat.

4. Prepare a wet towel to cover the root of the handbrake, which leads directly to the engine compartment, and the heat can run very well.

Generally, the effect of air conditioning is almost the same after doing this.
