Air conditioning maintenance knowledge, air conditioning maintenance knowledge and skills

Air conditioners are useful in both summer and winter, and if they are found to be damaged after a period of use, they need to be repaired. Maintenance should pay attention to the following 6 items, the first one, check the filter screen of the air conditioner, if the air conditioner can be started normally, but it can not emit cold air, it is likely that the filter screen is too dusty, the better way is to spray it with that special filter cleaning agent.

Second, the compressor pipeline contact, you can adjust the start of the high-pressure pipe and the low-pressure pipe by hand, or place the rubber pipe on the easy-to-contact pipe to avoid abnormal noise during the collision.

Third, after 20-30 minutes of normal operation of the compressor, touch the temperature of the suction pipe, exhaust pipe, compressor, evaporator outlet, condenser and other parts, and judge the quality of the refrigeration effect by the feel. The compressor temperature is generally between 90 and 100 °C.

Fourth, insufficient refrigerant or slight blockage of the system will cause frosting in the exhaust pipe.

Fifth, if there is too much refrigerant, both large and small valves will frost.

Sixth, the debugging function is used to judge the sensor failure, and the debugging function generally has automatic and forced refrigeration. The automatic function can be used to determine the malfunction of the indoor ambient temperature sensor.

When the air conditioner fails, we can first see if there is a problem with the connection of the indoor unit and the outdoor unit of the air conditioner, and at the same time whether there is dust on the fins of the air conditioner condenser.

After that, observe whether the indoor unit of the air conditioner and the fan of the outdoor unit are operating normally.

After that, whether the suction pipe of the compressor is condensed and the filter is frosted, whether the capillaries are blocked, etc., and at the same time, the air conditioning failure displayed on the display screen of the air conditioner can also be used to judge the failure of the air conditioner according to the failure of the air conditioner.

In addition to checking the failure of the air conditioner, we can also check it by listening. First of all, we can listen to the room celebration car of the air conditioner, guess whether the fan running of the outdoor unit and the indoor unit is smooth, and whether there is any friction sound or abnormal sound caused by resonance during the operation of the compressor. Then listen to the sound of the condensate flowing as it flows.

After listening and watching, you can also check by touching, the main purpose of touching is to perceive whether the temperature of each part of the air conditioner in the process of working is the normal temperature generated during operation, and we can check whether the fault of the air conditioner is caused by excessive temperature during operation.

- Is the air conditioner malfunctioning? With my 8 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.

First: When the air conditioner fails, you can go to the [Air Conditioning Fault Code Network] to check the brand and model of the air conditioner. Universal remote control** query can go to the universal remote control area for inquiry.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this will often amplify the existing faults, increase the operating costs, shorten the normal service life of the equipment, and lead to the early scrapping of the equipment.

The air conditioner is not refrigerated or does not refrigerate.

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold, and the spirit is frosty, and the fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way cross-gas is also common to pass back the manuscript to judge by fluorine.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

I hope you get better and better, and the new year will be smooth, all your wishes will come true, you will be healthy, and your family will be happy.

- Finally, I wish you all the best in your work, fix the air conditioner as soon as possible, and live happily ———

Broken air conditioner? In my eight years of aircon maintenance experience to tell you how to solve these faults, you should avoid a lot of detours.

First: When you encounter an air conditioner failure**, you can go to the [network] air conditioner failure** to inquire and reduce the brand and model of the air conditioner. Universal remote control** find.

The query of the corner can go to the universal remote control.

In the encounter, when the faulty air conditioner must be behaved in strict accordance with the scientific procedure, if the situation is not clear, the failure is unknown, when the uncertainty of blind action, dismantling.

The consequence of this often expands existing failures, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

No refrigeration or poor air conditioning.

The most common problem is the lack of fluorine air conditioners.

Turnkey return tubing via the first touch.

temperature to determine if the machine is cold Check that the fan speed may be lower and dirt and dirt to clean or replace.

If the pipe does not cool down, the pipe may have been flattened.

The return air temperature is not too cold and then penetrates deep into the air to determine.

The cold air intakes were also frosted fluoride.

Try the slowly scattered cream again, if there is a fluoride deficiency, it is a good decision, and it is not difficult to see.

Exhaust by age is not focused enough.

Stone strings are also common to determine by turning off fluoride.

The high-pressure scale must look dirty, and the refrigeration will slow down.

I wish you a better new year, docile, all wishes come true, good health, and happiness.

- Finally, I want the work to be carried out smoothly, and the air conditioner is repaired for the first half of --- happiness

- If you think it's good, you will have a good answer, give a good review, and wish you a better life ---

Air conditioning overhaul is an important part of ensuring the normal operation of the air conditioner, which can ensure that the air conditioner keeps working well in the hot weather in summer. Here are some ways to overhaul your air conditioner.

1.Clean the aircon filter.

An aircon filter is a critical component that prevents dust and other small particles from entering the aircon system. If too much dust and dirt is attached to the filter, the air flow will be reduced, reducing the efficiency of the air conditioner. Therefore, it is crucial to clean the filter regularly.

2.Clean the air conditioner, evaporator, and condenser.

The surfaces of air conditioner evaporators and condensers are prone to fouling and dust build-up, which are not only harmful to air quality, but can also impede air flow. Cleaning your evaporators and condensers regularly ensures that they are running smoothly.

3.Add refrigerant.

Refrigerant is the substance that cools an air conditioner, and if there is not enough refrigerant or leakage in the air conditioning system, it will not work properly. Therefore, it is important to regularly inspect and replenish the refrigerant.

4.Check the wires and connections.

Wires and connections play an important role in air conditioning systems. If there is a problem with them, it can lead to malfunction or danger. Therefore, it is necessary to check the wires and connections.

5.Check the thermostat.

The thermostat is a key component that controls the operation of the air conditioner. If something goes wrong with it, it may cause the air conditioner to fail to cool or heat up, so it needs to be checked regularly if it is functioning properly.

In conclusion, regular air conditioner overhauls can ensure that the air conditioner is working properly and extend its lifespan while avoiding additional costs due to air conditioner damage.

1. First of all, check whether the air conditioner is operating normally, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit, as long as one of them is not running normally, you need to ask a professional master to come to the door for maintenance.

2. Then check the filter screen of the air conditioner, if the air conditioner can be started normally, but it can not emit cold air, it is likely that the filter screen is too dusty, and the better way is to spray it with that special filter cleaning agent.

3. If the air volume of the fan is very small, then it may be that the fan motor is old and needs to be replaced with a new one.

4. Check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, you should add freon, and check whether there is a gas leak in the cold circulation system, and if there is a gas leakage, you have to make up for the leakage.

5. If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, only to the air conditioner air vent to have the air conditioner, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large to cause spring, it will be better to replace the air conditioner with a little more horsepower.

6. If the ventilation pipe of the air conditioner is installed for a long time, it may lead to a poor effect of transmitting indoor heat to the outdoors, so that the refrigeration is not very obvious, and a better location should be found to reinstall it, and strive to make the ventilation pipe shorter.
