Is the aircon gap refrigeration failure related to the SX4 Sunlight Illuminance Sensor 5

- Is the air conditioner malfunctioning? With my 7 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 conditioner failure** network] to inquire, down to the brand and model of the air conditioner.

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 often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of 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 frosty, and 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 gas is also commonly judged by fluoride collection.

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

If you still don't understand, it is recommended that you go to the [Air Conditioning Fault **Net] basic knowledge area and take a look at the maintenance cases to get started.

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 ———

- If you think it's good, please click on the answer, give a good review, and wish you a better life———

It should not matter that the two systems are in place.

It is best to find the original factory repair manual.

It should be the part of the circuit used to measure the ambient light intensity used in the automatic headlights, and the light measuring head is either in the fixed position of the ** rearview mirror, or at the root of the windshield near the wiper.

Your car's oxygen sensor is broken, and his position is in the first section of the exhaust pipe... **About 300 yuan.

The automatic air conditioner temperature sensor is broken! There's a dot at the front windshield! That's it.

.Sunlight sensors are generally used in two places on the car, one is automatic air conditioning (auto), and the other is the vehicle's lighting system, which is widely used.

1. Air conditioning: control the refrigeration (air conditioning) system (auto) according to the intensity of sunlight. The "heat radiation" caused by sunlight exposure is corrected by correcting the temperature control in the air conditioner.

The largest heat in the solar system is the infrared part, which is not visible to the naked eye but its "radiation" is the main body that affects the "heat" (temperature) in the car, and the sunlight sensor mainly measures the intensity of this part of the light (wavelength is about 900 nanometers), which is divided into single and dual zones according to different applications.

2. Lighting system: according to the intensity of the light, the lights (on and off) are automatically controlled, such as the application of modern automatic headlights.

Many modern cars are typically equipped with two of these sensors. Approximately under the front windshield (common but not absolute).

Detect that there is a problem with the sunlight sensor because you are in the house when you repair the car, it is normal to report this code, the problem of the air conditioner or the problem itself has nothing to do with the code, see if the low-pressure pipe is frosty, it may be that there is water in the pipeline, causing ice or the condenser is not cooled well, or the expansion valve is not good.

The sunshine sensor, also known as the rain sensor, is to control the lights and wipers, and the air conditioning system has nothing to do with it, the air conditioner sometimes works and sometimes does not work, the air conditioning system may be poor fluorine, and there may be a circuit failure, what fault is still to go to the service station to check.

My trolley was the same last year, we don't understand, and it costs more than 8,000 to get it! Alas!

Hello, is it windy for a while and windless for a while? Compressor blowers can all have problems.

The sunlight sensor has no fault code in the sun, and it is related to the compressor when it is cold.

If the line is troubleshooting, the sensor can only be replaced. In terms of wiring, it is recommended to measure the continuity and power supply between the sensor and the controller again according to the circuit diagram, and then consider replacing the sensor if there is no problem.

Temperature sensor checked.

The compressor is a driven fluid machinery that lifts low-pressure gas into high-pressure gas, and is the heart of the refrigeration system. It sucks low temperature and low pressure refrigerant gas from the suction pipe, drives the piston to compress it through the motor operation, and discharges the high temperature and high pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, so as to realize the refrigeration cycle of compression, condensation (heat release), expansion and evaporation (heat absorption).

The linear compressor uses the principle of magnetic levitation and the hydrodynamic structure of the spiral ring to compress the gas and provide power for refrigeration.

Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. A piston compressor generally consists of a housing, an electric motor, a cylinder block, a piston, a control device (starter and thermal protector) and a cooling system. There are three types of cooling methods: oil cooling, air cooling, and natural cooling.

Linear compressors have no shaft and no block, seal, and heat dissipation structure.

Generally, the compressors of household refrigerators and air conditioners use single-phase alternating current as the power source, and their structural principles are basically the same, but the refrigerants used in the two are different.

There is no cold steam in it, this is the compressor compression difference, it is recommended to repair or replace.

Air conditioning and refrigeration are mainly related to compressors, condensers, and evaporators.

After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure steam and discharged to the condenser. At the same time, the outdoor air drawn in by the axial fan flows through the condenser, taking away the heat released by the refrigerant, causing the high-pressure refrigerant vapor to condense into a high-pressure liquid. The high-pressure liquid is sprayed into the evaporator after passing through the filter and throttling mechanism, and evaporates at the corresponding low pressure to absorb the surrounding heat.

At the same time, the cross-flow fan continuously enters the ribs of the evaporator for heat exchange, and sends the cooled air to the room after heat release. In this way, the indoor air is constantly circulating and flowing to achieve the purpose of reducing the temperature.

The principle of air conditioning refrigeration is to reduce the indoor temperature by sending the hot air from the room to the outside through the physical changes between the refrigerants through the compressor. The effect of air conditioning refrigeration is related to air conditioning refrigerant, compressor, and air conditioning radiator, all three are indispensable, and the lack of any one will lead to air conditioning not refrigeration.

The direct relationship between the refrigeration of air conditioners is Freon!

Of course, voltage, filter dust, and space sealing conditions can also affect your cooling effect!

Finally, I wish you a happy family!

The air conditioner freon is not enough, the compressor is aging, and the air conditioner radiator is too dirty, which will cause the air conditioner to not refrigerate.

The size of the surface cooler, the size of the compressor, the charge of the refrigerant, the size of the condenser, the working environment.

The principle of air conditioning and refrigeration: the principle of air conditioning and refrigeration operation.

What is the principle of air conditioning and refrigeration?

It may be a poor contact.
