What is the problem of Gree s one to two inverter air conditioner s poor refrigeration effect

There are three main series in total: Gold Series, Green Series, and Calm King Series. 1.

On the other day, the design of the three series is similar, but the words on the top are different. 2. ;In terms of the internal unit, the Calm King series focuses on silence and adopts a low-speed unit, which is more energy-saving and environmentally friendly; The other two are 1; In terms of price, the three series are different, the gold series is generally high, and the remaining two series are generally low, so that Gree can cover all the ** range and get more benefits.

- Air conditioner refrigerator malfunctioning? With my 7 years of experience in repairing electrical appliances, I will tell you how to solve these faults, which should save you a lot of detours.

First: When the air conditioner refrigerator fails, you can go to the [air conditioner failure** network] to inquire, 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.

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 ———

Generally, the reason for the decline in the refrigeration effect of split air conditioning is caused by the leakage of refrigerant, and then it is necessary to supplement the refrigerant, and the reference ** is generally 80---150 yuan, and there will be differences in different cities.

The piping system is faulty.

Check whether the condenser is clean and clean the filter of the inner machine, as the condensant (freon) may leak. In serious cases, the system is dirty and blocked, the four-way valve is crossed, the internal and external fans are slowed down, and so on.

It is advisable to consult a professional (i.e. the person who repairs the inverter air conditioner) if there is a problem.

After a long time, it is necessary to add refrigerant to achieve the best refrigeration effect.

The slow refrigeration of air conditioners is caused by the lack of refrigerant. After using the air conditioner for more than three years, I found that the cooling signal was particularly slow and the effect was not very good. At this point, it is necessary to consider whether the refrigerant is missing.

You can ask a professional to check if the refrigerant is leaking, or if there is something wrong with the machine itself; If the air conditioner is slow because of the lack of refrigerant, the timely replenishment of the refrigerant can be pure, if it is found that the air conditioner is in the process of use, the leakage needs to find the location of the leak, we need to repair it, and then fill the refrigerant, so as to solve the problem of slow refrigeration. Pants care before start-up: Usually household air conditioners are shut down and deactivated in September, and they are not turned on until May and June of the following year, and they are out of use for more than half a year.

Therefore, before the air conditioner is turned on, a comprehensive "diagnosis" must be done, check whether there is a "problem" with the air conditioning equipment, and do a good job of maintenance and cleaning under the guidance of professional and technical personnel according to the results of the inventory; This maintenance and cleaning should be in place, including the shell, body, and filter of the outdoor unit and the indoor unit, and then start the trial operation to observe the refrigeration speed and effect.

The debugging method is as follows: 1. Check whether all lines (power lines and signal lines) and pipeline connection terminals are loose, and whether the phase sequence of power wiring is correct. 2. Whether the gas and liquid pipe valves are fully opened.

3. Whether there are unknown obstructions around the tuyere of the internal machine and the external unit. 4. Let the compressor be preheated for 8 hours (that is, the external unit is energized.) 5. Confirm that the additional refrigerant in the piping has been completed or more than 70% of the refrigerant addition has been completed.

6. Check the valve switch in the system before commissioning and starting: when the single module is single, the gas and liquid pipe valves and fierce doors are required to be opened, and the oil balance valve is closed; The double or triple module requires that the air pipe, liquid pipe, and mountain bridge oil balance valves are all open. Set the master and slave modules of the external machine

The detailed setting steps are as follows: before the unit is powered, select an external unit as the main external unit according to the wiring, and the SA8 dial code on the motherboard is set to the factory default "00", and the SA8 on the motherboard of the other external units is set to "10". (00" for the master module, "10" for the slave module). Shed annihilation.

Check the following conditions: The mode setting is wrong, the temperature and wind speed settings are unreasonable, please select the mode again, set the appropriate temperature and wind speed The filter screen is dirty, the air inlet and outlet of the indoor unit are blocked, and the angle of the air deflector is too small, please clean the filter, remove the obstruction of the air outlet, and adjust the angle of the air deflector The door and window, exhaust fan, etc. are not closed, resulting in poor room insulation effect, please close the doors, windows, exhaust fans, etc. The room area is large, and the air conditioner selection is small, so it is recommended to increase the wind speed.

1. Check whether the refrigeration mode of the air conditioner is set correctly.

2. Whether the voltage is normal.

3. Insufficient (or) leakage of refrigerant "called "refrigerant" refrigerant "potion" will cause non-refrigeration.

4. If the air conditioner filter is too dirty, clean the filter.

5. If the external unit fails (or) cannot work normally, it will cause non-refrigeration.

6. Professional maintenance personnel are needed to inspect (or) repair at home.

7. There are some unprofessional maintenance companies, perhaps because there is little work (finding) can not do anything, (or) to low-quality work, but a part is damaged (or) materials for charging, in the case of our knowledge, the money is spent in vain, and there may be some problems in our use (process) in the future, and there will be no safety guarantee in the future.

Mine is also this problem, I bought it in May '18 and installed it and didn't use it a few times at the end of June. It's not cool at 26 degrees, and it feels cool below 25 degrees, but the room temperature only drops by one degree after two hours. Looking for after-sales service but said there was nothing wrong, and some of the headlines said that it was very cold at 27 degrees

According to what you say, this situation is normal, because the inverter air conditioner starts to reduce the frequency when the temperature difference between the room temperature and the setting temperature is less than 3 degrees, because you set 25 degrees, when the indoor temperature is lower than 28 degrees, the air conditioner begins to reduce the frequency, and the indoor temperature drops to 26 degrees when the air conditioner is basically at the lowest frequency, and the cooling capacity of the air conditioner at that time is basically very small, and it can only be maintained to 26 degrees, which is normal, when you adjust the set temperature to 23 degrees, the difference between the set temperature and the room temperature is 3 degrees, and the air conditioner will immediately increase the frequency. It's normal, don't worry.

My family bought Gree inverter refrigeration poorly, looking for maintenance and saying that there is no problem, and this side will not be refunded, which is too annoying.

The remote knowledge brothers ascended to the heights, and there was one less person in the dogwood.
