For the summer driving, the normal operation of the sprinkler air conditioning system becomes the key to driving. At present, some drivers do not know much about the use and maintenance of the sprinkler air conditioner. Here we suggest that the sprinkler driver should be your sprinkler before entering the summer. Prepare for inspections, especially for sprinklers that are 4 years old or older.
　 1. Clean water tank and condenser
The water tank and the condenser are important components of the sprinkler cooling system and the air conditioner. As the vehicle is used for a long time, dust, sand, catkins, etc. will be trapped in the gap between the two, which will affect the water temperature and air-conditioning cooling. Performance.
　 2. Check the water pressure of the sprinkler and replace the refrigerant
First check (H) is the high-pressure detection tube and (L) is the low-pressure detection tube, respectively connected to the fluorine pressure detection table, after the completion of the fluorine pressure gauge connection, the sprinkler ignited to start idling.
At this time, the air-conditioning switch is turned on, and the air-conditioning system is turned on to start the maximum operation test. The high pressure in the idle state pressure detection should not exceed 300, and the low pressure in the idle state should not exceed 60.
After a few minutes of idling, observe the change in gauge pressure by raising the speed of the oil and check that the air conditioner compressor is operating properly. Then remove the original refrigerant (134a), the weight is generally between 250g-300g, receive a pressure gauge to prepare for fluoride, it is recommended that the general two or three years of the car with a bottle, some models can add two bottles.
3. Choose the right oil viscosity in summer
In summer, many sprinkler drivers complained about fuel consumption. In fact, they can choose to use lower viscosity lubricants in the summer. Of course, this is because the vehicle condition is good and the wear is relatively small. For a relatively large number of kilometers, old cars with a longer age should still use slightly more lubricating oil.
Take Castrol Multipolar as an example, the viscosity is 0W-40, which is suitable for most of the vehicles on the market. The unique TiFST technology can guarantee the short-term and long-term performance of the engine and reduce the friction and deposition of engine surface components. The generation of objects improves the overall performance of the engine in terms of response speed and the like.
4. How to clean air conditioning duct replacement filter?
The life span of the original air-conditioning filter of the sprinkler is 12,000 km. This is generally under normal conditions. The method of cleaning ventilation ducts is very simple. It is to use wet towels to block the outlet of the air conditioner and adjust the air-conditioning speed to the maximum, so that the dust will be sucked on the towels. In addition, air-conditioning duct cleaning agents can also be used to assist the high-pressure air gun cleaning 2 to 3 times to achieve the purpose of cleaning.
5. What should be cleaned of musty air conditioning?
Some sprinkler drivers will find that when the air conditioner is turned on, the air outlet will blow out a musty smell, which is because the reason for not cleaning the air duct in time. The easiest way is to solve the problem by cleaning the air duct. As we mentioned above, the user can purchase air-conditioning cleaning agent to assist the operation. When the air conditioner is used, it should not be closed immediately. Instead, the air supply switch should be turned on for 5 minutes.
　 6. Correct use of air-conditioning internal and external circulation systems
Sprinklers must pay attention to the use of internal and external circulation systems during the summer. Many models are now automatic air conditioners, while some models are manual air conditioners. At this time, we must pay attention. When the external circulation is used, the air conditioning enters the wind from outside the vehicle, while the internal circulation is the circulation of air inside the vehicle.
Internal circulation can improve the air-conditioning effect, but prolonged use of the internal circulation will reduce the air quality inside the vehicle and may make people feel dizzy. Under normal circumstances, it is recommended that everyone use the outer circulation to allow fresh air to enter the car and improve air quality.
7. Foil can also lower the temperature
In summer, many sprinklers will also stick solar membranes to their cars. The films will have anti-ultraviolet rays, increase air-conditioning efficiency, and heat insulation.
If your sprinkler has not been cleaned for a long period of time, we suggest that you may check the above method to make summer travel easier and more enjoyable.
