Three Suggestions for Summer Maintenance of Car Air Conditioners and Eight Attentions

◆ Note 1: The modification of air conditioners should be cautious. It is not recommended to modify the car's air conditioner, because the original air conditioner It is matched with the engine of the car. If it is modified at will, it will affect the performance of the car.◆ Note 2: The air conditioner temperature should not be too low. Choosing the appropriate air conditioner temperature is the first step in air conditioner maintenance.

Notes on car air conditioning maintenance in summer Introduction: I have sorted out the relevant knowledge of car air conditioning maintenance precautions in summer to solve the confusion encountered by car owners in the process of using the car.

The manual operation time of the air conditioner should be more than 2 minutes apart. 0 Prevent the electrical system from moisture. The electrical system is prone to leakage after moisture, so water should not enter the parts of the electrical system, especially in the rainy season, and pay more attention to moisture-proofing.

In summer, the empty switch in the car is often turned on. After parking, the empty switch must be turned off to avoid the empty switch automatically opening at the next ignition time, increasing the engine burden.? Once the cleaning air filter element is hot, the utilization rate of car air adjustment will increase.If the air conditioning system is not cleaned, it will breed bacteria and endanger the health of drivers and passengers.

Abstract: In summer, car air conditioners are used a lot, so you should pay attention to cleaning and maintenance. Clean the car air conditioner about once a year. If there is a strange smell, it should be cleaned in time. In addition, the filter needs to be cleaned once a month. It is best to clean the air conditioner on a large scale before using it in summer. Car owners can check the car manual to clean it by themselves, or consult the car 4S store.

Six notes for the maintenance of car air conditioners in summer. The modification of air conditioners should be cautious. It is not recommended to modify the air conditioner of the car, because the original air conditioner is matched with the engine of the car. If modified at will, it will affect the performance of the car.

How is the car air conditioner composed and how to maintain it?

Regularly replace the air filter. When the air conditioner is in operation, the air entering the car must be purified by the air conditioner filter before entering the car. After long-term use, the air filter element will be blocked by dust and cannot play a purifying role. Almost every six months, the air filter replacement can make the air cleaner and fresher.

Maintenance of car air conditioner Car air conditioner is one of the necessary devices in vehicles nowadays, and it has become the most important tool for everyone to cool down. Especially for friends who drive out, a good and stable air conditioning system is the most indispensable.

Frequently clean and regularly replace the air conditioner filter. Many car owners often wash their cars, but do not pay attention to the maintenance of their cars. There are often heavy rains in summer, and the weather is relatively humid. If the air conditioner filter is not cleaned in time, it will cause a strange smell and moldy smell in the car.

First of all, the air conditioner on the car is mainly composed of condensers, compressors, evaporators and storage tanks. Among them, the condenser and compressor are equivalent to the external unit of the split air conditioner in the car. The condenser is mainly installed behind the front bumper, which is similar in shape to the water tank.

How to repair the circuit of the car air conditioner?

1. The maintenance of the automobile air conditioning circuit requires certain electrical knowledge and skills. The following are some common maintenance methods: check the circuit connection: check whether the connection of the air conditioning circuit is tight, whether there is looseness or corrosion, and if there is a need to reconnect or replace the connector.

2. Check the relays and switches. Relays and switches are an important part of the automobile air conditioning circuit. By checking the connection and resistance value of the relay and switch, you can determine whether they are working properly. If necessary, replace the damaged relay or switch.

3. First of all, check whether the power supply of the car air conditioner is normal. Check whether the battery is charged, whether the fuse is intact, whether the battery connection is loose, etc. If there is a problem with the power supply, you need to solve the power supply problem and repair or replace the relevant parts.Step 2: Check the compressor. Next, check whether the air conditioner compressor is working properly.

4. Check the power supply: First, make sure that the power supply of the car is working properly. Check whether the voltage of the battery is normal, and whether the fuse and relay are working properly. Check the compressor: The compressor is the core component of the air conditioning system and is responsible for compressing the refrigerant. Check whether the connection of the compressor is tight and whether the electrical connection is normal.

Maintenance of car air conditioner condenser

First of all, use tools to detect whether the condenser has fluorine leakage. If not, you can consider repairing or replacing the condenser. If a leak is found, it needs to be repaired with a special sealant, or the condenser needs to be sent to a professional repair shop for treatment.

Condensers are generally not repairable. If they are damaged, they will be replaced directly. The failure of the condenser is usually blocked or leaking. If it is a leak, the condenser needs to be replaced directly. If it is blocked, it can continue to be used after repair. The condenser is located in front of the water tank and is used for refrigerant heat dissipation.

Condensers are generally unrepairable. If they are damaged, they will be replaced directly. The failure of the condenser is generally blocked or leaked. If it is leaked, the condenser needs to be replaced directly. If it is blocked, it can continue to be used after repair. The condenser is located in front of the water tank, and this part is used for refrigerant heat dissipation.

Maintenance suggestions for modified vehicles: replace the elonged condenser. If you want to improve the engine heat dissipation, you can upgrade the water tank to a thickened type; if you want to improve the heat dissipation effect, you can makeUse an elongator water tank, and modify the line of the cooling tank and the condenser fan to run together, whether it is air conditioning or heating the car, it works at the same time.

How much does it cost to repair a broken car air conditioner?

The price of repairing car air conditioners in S stores varies depending on the region, brand, model, hourly cost, material cost and other factors. Generally speaking, it is between 2,000 yuan and 4,000 yuan. First of all, the cost of repairing the air conditioner mainly includes labor and material costs.

Generally speaking, the maintenance cost of fluorine leakage of car air conditioners is roughly between 200 and 500 yuan. It is recommended to repair the fluorine leakage problem in time to avoid further damage to the air conditioning system and increase the maintenance cost.

How much does it cost to add fluorine to the car air conditioner?If the car air conditioner must be refrigeranted, it is better to find a reliable maintenance shop. The cheap one may only cost dozens of yuan, and the expensive one may cost about 200 yuan. You can go to a few more stores to ask and choose a more affordable one to add fluorine.
