Gree air conditioner is not cooling, is it an electric fan?

1. The outdoor unit does not work, and the specific reasons include: 1. The refrigeration mode of the remote control is set incorrectly; 2. The set temperature is higher than the ambient temperature of the room; 3. The indoor and outdoor power supply cables are broken; 4. Shutdown protection in case of air conditioner failure, please refer to the complete list of air conditioning failures for specific meanings; 5. The main board of the air conditioner computer is damaged.

2. The compressor does not work, and the specific reasons include: 1. The compressor is damaged and does not start; 2. The starting capacitor of the compressor is damaged; 3. The compressor with poor heat dissipation of the outdoor unit stops working; 4. The compressor is overloaded and the starter is damaged; 5. The compressor power supply voltage is insufficient and too low.

3. There is no refrigerant in the air conditioner, and the specific reasons include: 1. The air conditioner has not replenished the refrigerant for a long time; 2. There is refrigerant leakage in the air-conditioning system (copper pipe or high and low pressure valve of outdoor unit); 3. There is a blockage in the air-conditioning and refrigeration system; 4. Excessive air-conditioning and refrigeration; 5. Poor refrigeration of refrigerants (inferior refrigerants, with moisture);

4. Poor heat dissipation of the outdoor unit, the specific reasons include: 1. The installation environment of the outdoor unit is not good; 2. The outdoor fan motor is damaged and does not rotate; 3. The speed of the outdoor fan is slow; 4. The dust of the fins of the heat dissipation net of the outdoor unit is blocked; 5. The fan capacitor of the outdoor unit is damaged.

The reason why Gree air conditioner is not cooling.

1. There is not enough freon (also known as "refrigerant" is not enough).

This is a normal situation, generally appears in the use of three to four years of old air conditioners, air conditioning is not completely not refrigerated, but the effect of refrigeration is not good enough, this is because the old air conditioners are used as freon refrigerant, long-term use will volatilize, in addition to improper installation caused by freon leakage and the machine itself problems.

Solution: Adding refrigerant can solve the problem of air conditioning not cooling.

2. The voltage of the power supply is not enough.

The power supply voltage is unstable, and it often fails to reach the normal voltage, especially during the peak of electricity consumption. Of course, this kind of problem is obviously not something that a skilled air conditioner maintenance master can solve, and we must start from the aspect of providing a stable voltage to solve the problem.

Workaround: Maintain the normal supply voltage.

3. The power of the air conditioner is not enough.

This is also one of the common reasons for not refrigerating, but there are many reasons for this kind of non-refrigeration, such as small power air conditioning pipes and large area of the room, and some although the air conditioning power and the room area seem to match, but because the room is relatively unsealed (such as doors and windows are wide open, etc.) or there is a heat source in the room (such as a lot of computers), of course, the glass room is also one of the heat sources, etc.

The solution is to match the power of the air conditioner and the cooling capacity required by the space; change the conditions of the environment in which it will be used; Increase the airtightness of the use environment; Reduce the heating source in the environment where the air conditioner is used to solve the problem of non-cooling.

4. The external environment temperature is too high.

This kind of non-refrigeration situation is common in our outdoor unit installed in a relatively closed space or the temperature around the outdoor unit is too high, so it is extremely easy to cause the heat emitted by the radiator to flow away due to the lack of air circulation in the small space where the outdoor unit is located, so that the air conditioner is not refrigerated; There is also a common saying that when the outdoor temperature exceeds 43 degrees, most air conditioners are difficult to transfer indoor heat to the outside through the radiator of the outdoor unit, which will also cause the air conditioner to not refrigerate.

Solution: Change the environment in which the outdoor unit is used (move away from the high temperature environment or make the surrounding air of the outdoor unit more easily circulated).

5. The air conditioner is not cleaned and maintained for a long time.

Because the outdoor unit is installed outdoors, after a long time of use, the radiator will absorb a lot of dust, garbage and other dirt, so that the heat dissipation effect of the radiator is poor and the air conditioner is not refrigerated; In addition, ignoring the maintenance of the air conditioner for a long time will make the room air unhygienic, more susceptible to air conditioning diseases, increase power consumption, and shorten the service life of the air conditioner.

Solution: Clean and maintain the air conditioner to make it easier to dissipate heat from a clean outdoor unit.

6. The copper pipe between the outdoor unit and the indoor unit is too long.

Some air conditioners are too long due to the need for installation or unreasonable installation, so that the heat transfer efficiency is low and will also cause the air conditioner not to refrigerate.

Solution: Minimize the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner.

What is the reason why Gree air conditioner does not refrigerate.

The air conditioning fan will not be refrigerated, the air conditioning fan itself is a product that fools consumers, adding the word "air conditioning" in front of the ordinary electric fan has deceived many consumers, and what air conditioning is 、......Look to keep your eyes open.

It's time to change the water!! See if the other features are faulty!! Be specific.

Isn't it time to add fluoride, you can add it and try it.

1. First of all, confirm whether your Gree air conditioner is a single chiller (some customers buy a single chiller, which can only be cooled but not heated);

2. If the outside temperature is too low, it will also affect the heating of the Gree air conditioner, check the set temperature of your Gree air conditioner (only if the set temperature is higher than the indoor temperature can it work normally).

3. It may be that Gree air conditioner lacks freon, and the lack of freon is also one of the important factors that cause Gree air conditioner not to heat, and it is necessary to add freon to Gree air conditioner. Due to the long-term placement of the external machine, wind and rain, coupled with the lack of maintenance, the copper pipe connecting the internal machine and the external machine is easy to age, the interface is loose, and the freon leakage will be caused by a long time, and the freon pressure in the pipe is insufficient, and the temperature cannot reach the set value.

4. If all of the above are confirmed to be fine, it is necessary to start from the conversion principle between refrigeration and heating of Gree air conditioner, that is, the four-way valve, the problem may lie in the four-way solenoid valve or its control circuit, and it may also be the low fault of the AC contactor, thermostat and over-temperature fuse of the electric heater and its power supply circuit. Check whether there is voltage and four-way valve transfer switch on the coil of the four-way solenoid valve, sometimes the internal air pressure is not enough, and the four-way valve can not be converted.

5. There are also circuit system line control faults are also more common, such as the external machine does not work, most of them are capacitor or temperature probe or motherboard faults.

The air conditioning fan is cooled by circulating water and ice crystals.

Without ice crystals, the high temperature of the water is the same as an electric fan.

If the mode setting is incorrect, and the temperature and wind speed settings are unreasonable, select the mode again and 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: clean the filter screen, remove the obstruction of the air outlet, and adjust the angle of the air deflector.

Doors and windows, exhaust fans, etc. are not closed, resulting in poor room insulation: close doors, windows, exhaust fans, etc.

The room area is large, and the air conditioning type is small: it is recommended to increase the wind speed.

When heating, the electric auxiliary heating function of the air conditioner is not turned on: Turn on the electric auxiliary heating function of the air conditioner.

1. There are many reasons why the air conditioner cannot be refrigerated when it is windy

1. Whether the set temperature is lower than the actual temperature of the room; Because when the set temperature is reached, the compressor will automatically shut down.

2. Whether the compressor is running normally; This is because it is impossible to refrigerate the compressor if it is not running.

3. The compressor cannot be refrigerated after running: the pressure of the refrigerant (fluorine) drops (fluorine leakage).

4. Whether the function setting of the remote control is wrong (whether it is in the refrigeration function).

2. Solution:

2. Try to shorten the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner3. Clean and maintain the air conditioner to make the clean outdoor unit more tolerant of late heat dissipation.

4. Ensure that the voltage at home is stable, especially during the peak period of electricity consumption, buy a higher resistance and voltmeter to monitor the voltage at all times.

5. Change the use environment of the outdoor unit, and try to install it in a well-ventilated place.

Ask how to solve the compressor problem.

Question: The compressor is not working.

The answer is that it does not work: 1. The general situation is caused by long-term operation under the shortage of Freon, and the freon is supplemented for the air conditioner; 2. The air in the system is not discharged clean during installation, there is ice blockage from time to time, and the load of the compressor increases, so the quality should be strictly controlled during installation; 3. If the contact of the power conductor socket is poor, or the diameter of the power conductor is thin or aging, check whether the power conductor is aging; 4. If the electrical line is faulty, the high-voltage disconnection is disconnected, press the differential pressure relay reset button down and wait for the pressure change to close the contact or readjust the disconnection pressure. The compressor is a driven fluid machinery that lifts low-pressure gas into high-pressure gas, and is the heart of the refrigeration system, which sucks low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it through the motor operation and drives the piston, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle.

These are the reasons for pro.

Specifically, it needs to be overhauled.

Causes and solutions for air conditioners that are windy but not cooling:

1. The compressor has no refrigerant, add refrigerant.

3. The solenoid valve is not reversed: detect whether the solenoid valve is normal, and replace the solenoid valve if it is not on/off.

4. System failure: check whether the capillary is dirty, oil or ice blocked, if the air conditioner is not refrigerated when refrigerating, it is generally ice blockage, if the nitrogen blowing pipeline blows out the stolen goods or is not smooth, it means that the dirty plug or oil blockage, if there is no refrigerant in the open system, the refrigerant leakage, check the leakage point maintenance.

5. Compressor failure: the whole machine is not refrigerated, open the system, check whether there is enough refrigerant spray, determine whether it is refrigerant leakage, no leakage, and check whether the compressor is not exhausted.

First, it may be that the refrigerant leakage is insufficient (commonly known as "refrigerant" is not enough), and the refrigerant can be added.

Second, the power supply voltage is not enough, and the compressor cannot operate normally. It is recommended to install a voltage regulator.

3. The refrigeration power of air conditioning is small and the room area is too large; Room insulation is not effective. Take these factors into account when choosing an air conditioner.

Fourth, the external ambient temperature is too high, and the refrigeration time is longer than usual.

5. The air conditioner is not cleaned and maintained for a long time. Wash in a timely manner.

6. The copper pipe connecting the indoor unit and the outdoor unit is too long. Find a professional for commissioning.

The air conditioner fan is to put ice cubes in it to blow out cold air, and there is no cooling capacity. The air conditioner fan does not have a refrigeration system. It is actually an electric fan with a water cooling unit.

It has no compressor, does not use freon, and relies on a built-in water pump to keep water circulating through the machine, cooling the surrounding air. In this way, the wind emitted by the fan blades has an icy cold feeling. There may be several reasons why the air conditioner fan is not cooling:

Too much dust in the air conditioning fan: Generally speaking, the refrigeration effect of the air conditioning fan is not good, partly because there is too much dust in the air filter, and foreign objects block the air outlet of the internal and external units. The function of the filter is to absorb dust from the air.

If there is too much dust and it is not cleaned up in time, it will block the air circulation, resulting in a decrease in the air outlet volume, resulting in the refrigeration capacity in the machine cannot be brought out by the flowing air in time, resulting in insufficient refrigeration capacity. When purchasing an air conditioning fan, we should pay attention to the following aspects: (1) When purchasing an empty potato rolling ling fan, we should pay attention to whether the three guarantees are complete.

It must be marked with 3C, and only products with 3C have quality and safety guarantees. (2) It is best to buy an air conditioner fan with ice crystals to refrigerate. This air conditioner fan with ice crystals cools better than other types.

Other refrigeration methods include water curtain refrigeration, which has the advantages of small size, low power consumption and low power consumption. Pump refrigeration has the advantages of low noise and uniform refrigeration, but it is high.

1. There is too much dust in the air conditioner. Generally speaking, the refrigeration effect of air conditioners is not good, partly because the air filter has too much dust and the vents of the internal and external units are blocked by foreign objects. The function of the filter is to adsorb the dust in the air, if the accumulated dust is too much and not cleaned in time, the air circulation will be blocked, resulting in the reduction of the air outlet volume, resulting in the heat production in the machine can not be brought out by the flowing air in time, resulting in insufficient heating capacity.

2. Lack of fluoride. At present, the air conditioner commonly used by people works by absorbing heat from the outside air when freon evaporates. If there is a lack of fluorine, it will not be able to absorb heat and will not work normally.

When the outside temperature is low, the temperature difference with the evaporation temperature of Freon is small, and the heat exchange effect becomes worse. In addition, if the nut at the copper pipe horn is not tightened during the installation of the air conditioner, or the machine has been moved, fluorine deficiency should be considered.

3. Line control failure. For example, if the external unit is not working, it is most likely due to the failure of the capacitor, temperature probe or motherboard.

4. Improper use and maintenance. Nearly eighty percent of the air conditioner stool heating failure is not a machine problem, mainly due to the user's use, improper maintenance and other factors to make pure leather, for example, daily use is not carried out in accordance with the instructions for use, and there is no habit of caring for household appliances, when the climate is bad, do not pay attention to check the environment where the air conditioner is located.

5. The voltage is unstable. In winter, the amount of electricity used for heating will increase greatly, which may lead to poor voltage instability or too low voltage, causing the air conditioner to not work normally.

The reason why the air conditioner is not refrigerated, one is that the air conditioning filter should be cleaned, and the other is that it is time to add fluoride to Tanpi, it is recommended that you first send a letter to clean the filter and congratulate it, if it is not refrigerated, you can ask a professional to come and take a look.

1. Reason: The air conditioner of the air conditioner under normal operation, the temperature difference between the supply air and the return air (indoor temperature) should be more than 8, if it does not reach the buried orange, it means that the refrigeration capacity of the air conditioner is not enough, and the reason should be identified. The common causes may be:

1) The refrigeration load is overloaded or the room is too large.

2) The installation site is inappropriate, the airflow circulation is not sufficient, etc.

2. Solution:

1) First of all, find out whether it is caused by the excessive liquid load of the air conditioner of the air conditioner, and try to reduce the refrigeration load or increase the cooling capacity of the air conditioner.

2) Then look at whether the air conditioner of the air conditioner is properly installed, if it is not suitable, the cold air will not blow around the person, so that the person does not feel cold. When the airflow circulation of the air noise regulator is not smooth, such as the evaporator has a lot of dust, the gap between the fins is blocked, or the air filter is blocked by dust, the circulating air is reduced, and the cooling capacity of the air conditioner of the air conditioner can not be fully utilized.
