How to turn on the air conditioner correctly.
When turning on the air conditioner, the AC switch must be turned on, so that the switch of the compressor can be turned on, otherwise it can only turn on the fan to blow the air, and it cannot play the role of refrigeration.
When to turn on the car air conditioner.
No matter how hot the temperature is in the car, or if the car is parked in the garage, the car will wait for the engine to stabilize after ten seconds before turning on the air conditioning. At this time, we can increase ventilation and pull all four windows down at the same time. The large air flow can discharge dirt and harmful gases from the pipes. In the presence of sunlight, the temperature in the cabin is higher than outside, and when the windows are opened, the hot air inside will also be exhausted through the windows, so that the cooling time of the air conditioner can be reduced. The whole process won't be long, probably.
For a minute or two, then close the window and let the air circulate.
When to turn off the car air conditioner.
Our advice is to turn off the AC of the air handling unit 2-3 minutes before arriving at the target location, at which point the air flow switch is not turned off and the fan continues to supply air. The idea is to keep the air-dry air dry and avoid germs growing inside. If mold grows in the evaporation tank of the air conditioner, the environment in the car will deteriorate.
The use of internal and external circulation of automobile air conditioners.
In a good external air environment, external circulation is used to continuously deliver fresh air from the outside to the car to ensure the freshness of the air in the carThe method of internal circulation is used to block harmful gases from the outside of the vehicle. It is important to note that when the wind blows on the window, the system automatically goes into an external circulation, which is not a fault.
About the air conditioner odor.
An unclean inside of an air conditioner or an unclean evaporation tank can produce odors. The solution is to replace the air conditioner core first, and if the smell has not disappeared, then the evaporation box of the air conditioner must be cleaned. The core of the automobile air conditioner should be replaced twice in a year, once in winter and once in summer, and if the use environment is poor, it is necessary to increase the number of replacements.
What's going on with insufficient refrigeration.
First, if the refrigeration effect of the car is worse than before, then the first thing to check is the air conditioning core to see if it is dirty, if the air conditioning core is dirty, it will affect the circulation of air, and the air flow is too small, the refrigeration effect will also decline. Second, if the car has been there for a long time, check whether the condenser is blocked, if the condenser is blocked, it will not only affect the heat dissipation, but also cause the refrigeration effect to decrease, then you only need to clean the condenser. Third, there is no problem above, that is, to check whether the refrigerant is not enough, which requires special testing instruments. It should be pointed out that the cooling effect of different models will be different, and if the cooling performance of the vehicle itself is not good, there is no solution.
Which direction should the wind blow.
According to the principle of cold air sinking, the air conditioning air should blow upward, that is, the air outlet should be adjusted to a level or slightly upward, but not directly facing the driver. If the wind is downward, then the passengers in the back seats will feel the heat.
