Cologne air conditioner is a good person, please come in. Is the air conditioning in Cologne good

Room temperature 30, set 28, when the room temperature is 26 27, the external unit stops working, when the room temperature reaches 29, start again. Normal!

And you say "can't be stable at 29, but hovering between ", the control circuit is actually in a critical state because you are set at 28. That is to say, the temperature difference range of your air conditioner temperature controller is about 3, which is also normal, because the temperature difference range is too large, the indoor temperature will be cold and hot, and the temperature difference range is too small, the air conditioning compressor will start and stop frequently, which will affect the service life of the compressor.

To sum up, your air conditioner is normal and without any faults.

I don't know if you are uncomfortable with the noise of this air conditioner when it starts, or what, please state it clearly so that I can help you analyze it again.

This phenomenon is also the difference between ordinary air conditioners and inverter air conditioners that users can feel the most. If the landlord can not adapt, it is recommended to buy inverter air conditioner, inverter air conditioner outdoor compressor is always working, it is according to the indoor temperature to control the speed of the compressor and the opening of the expansion valve of the indoor unit to control the refrigeration capacity, the indoor temperature can basically reach a constant temperature state. There is no start-up or shutdown.

Moreover, under the constant temperature working state, the speed of the outdoor unit is very low, and the noise is very small (including the speed of the external fan is also very low at the same time (but there are also some brands of external fans that do not change speed)).

See what you mean, it is a routine for air conditioning control systems to use relays, and almost all air conditioners are controlled by relays, which is not a design flaw.

You are too sensitive to this sound, but there is still a way to improve, that is, to change all the electromagnetic relays to solid-state relays, so that the relay does not have any sound when it works, and the modification is extremely simple, you can ask someone who understands electronic circuits to change it, the cost is very low, it is estimated that it is less than 100 yuan.

I used to sell Cologne air conditioners, I didn't meet the situation you said, you can find the reason first, first look at how your home voltage to the wires and voltage of the air conditioner, (the air conditioner needs a lot of current to start, the wire is thin or the voltage is not enough to turn on.)

Second, you say that you have changed the indoor unit, then it is not that the indoor unit has a problem, you find someone to see if the outdoor unit has a problem with the circuit, or the starting capacitor.

Check the outdoor unit, measure the voltage with a multimeter when the machine is started, to see if it is lower than 180V, if it is lower than this value, it means that the fault lies in this. If the voltage is above 200V at the time of start-up, the reason for the failure to start normally is likely to be caused by the poor contact of the temperature sensor of the indoor unit.

Make the indoor unit relay tick, isn't it a problem that your circuit is too small?

Hello, dear. Cologne air conditioning was good. Kelon is Hisense's brand hand, and Hisense Kelon Electric Co., Ltd. is one of China's largest white goods manufacturing enterprises, founded in 1984, headquartered in Shunde, Guangdong, China, mainly producing refrigerators, Bi lead celery air conditioners, freezers and washing machines and other series of products.

In addition, Kelon Air Conditioning has developed and launched the world's first dual-mode fluorine-free inverter air conditioner with the function of "one-key dual-mode, full energy saving", which has advantages in technology. Kelon's air conditioning products also have fully automatic cleaning technology, which has the characteristics of low noise and high efficiency and energy saving. In terms of after-sales maintenance, Kelon air conditioner Hu's eggplant also has a professional after-sales service and installation service team of "three points of purchase and seven points of installation".

Among the air conditioners around 2000 yuan, Kelon is definitely one of the most worthwhile brands.

Cologne and Kelon are not the same brand.

Kiss. Is the brand you looking at Cologne?

At present, only the brand "Kelon" appears on the market. Not Cologne's. "Kelon" is a product of Hisense Group.

Reason 1: There are many reasons why the air conditioner is not refrigerated, when checking why the air conditioner is not cooling, you first need to check whether the power supply of the air conditioner is plugged in, and whether the connection between the air conditioner and the power supply is not working. If the air conditioner is not connected to the power supply, of course, there will be no refrigeration.

Maintenance method: If there is a problem with the power supply of the air conditioner, you only need to plug the power supply of the air conditioner back in to ensure that the air conditioner can be energized normally.

Reason 2: After checking the power supply of the air conditioner, check whether the voltage of the air conditioner is unstable or insufficient. The voltage of the air conditioner is unstable and cannot reach the predetermined voltage of the air conditioner, just like people work without food, and the air conditioner will work very hard. Generally, the voltage is unstable during peak periods.

Maintenance method: This is not a situation that can be solved by means of a method when the air conditioner is not refrigerated, and it is necessary to start from the aspect of stabilizing the air conditioning voltage.

Reason 3: Why the air conditioner does not refrigerate, sometimes it is similar to the reason why the refrigerator does not refrigerate, all because the refrigerant is not enough, resulting in the air conditioner or refrigerator not refrigerating. Generally, the air conditioner has been used for a long time, the refrigeration effect of the air conditioner will become worse, and the refrigerant of the air conditioner will gradually volatilize with the change of time.

Maintenance method: The refrigerant of the air conditioner is not enough, as long as enough refrigerant for the air conditioner is added, the problem of air conditioning not being refrigerated can be solved. However, if the refrigerant of the air conditioner is not enough because of the leakage of refrigerant, it is necessary to seal the cavity of the leaking part of the air conditioner by welding and repairing, and then add enough refrigerant to solve this problem.

Reason 4: The air conditioner is not cleaned for a long time, which will also lead to the situation that the air conditioner is not cooled, and the dust accumulation on the radiator of the air conditioner for a long time will make the radiator of the air conditioner unable to dissipate heat in time, and the heat dissipation effect will deteriorate, resulting in the air conditioner not being refrigerated. If the air conditioner is not maintained for a long time, it will make the air produced by the air conditioner carry a lot of germs, so that the air in the room will be polluted, and it is easy for people to suffer from air conditioning disease, and the power consumption of the air conditioner will also increase, shortening the service life of the air conditioner.

Maintenance method: timely cleaning and maintenance of the air conditioner, so that the radiator of the air conditioner can dissipate heat normally and improve the heat dissipation effect of the radiator.

Reason 5: The power of the air conditioner is not enough is also one of the factors that lead to why the air conditioner is not refrigerated, the power of the air conditioner is not enough may be because the power of the air conditioner is small, but it is necessary to provide a large space for refrigeration, or the sealing of the room is poor, the doors and windows are not closed, and there are more heat sources in the room.

Maintenance method: to deal with the problem of small power of air conditioning but to provide cooling capacity of large space, it is necessary to match the power of air conditioning with the size of the room providing cooling capacity, and at the same time, there are more heat sources in the room, so it is necessary to improve the use environment of the room and increase the sealing of the space.

If the external compressor does not rotate, it will not be refrigerated, and if there is fluorine leakage, it will not be refrigerated. There is also a low voltage, and the air conditioner does not refrigerate.

Recall malfunction? With my 10 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 inquire when you don't know, down to 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 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.

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 the work to go well, fix the air conditioner as soon as possible, and live a happy ———

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

Okay, why haven't I heard of the Cologne brand?
