AUX air conditioner does not refrigerate, you have to hit the portable feeling to cool, why?

According to what you said, it is estimated that there is a problem with the room temperature sensor of the indoor unit, so find someone to check it.

There are many reasons why air conditioning doesn't cool well:

1.The thermostat is not properly adjusted and does not play the maximum function of refrigeration, resulting in the room not being able to cool down, which can be solved after adjusting the thermostat.

2.Poor installation of the air conditioner will also lead to uneven indoor temperature or poor cooling effect, which requires readjusting the installation position of the air conditioner.

3.The power supply voltage is too low, causing the air conditioner to not be easy to start, stop after starting, or blow the fuse. This is not a fault, as long as the cause of power supply is checked, it is the power grid voltage is too low, the user should install a power regulator to make the voltage reach 220V, so that the air conditioner can be used normally.

4.The high temperature of the outside environment and the large number of people indoors increase the heat infiltration from the outside world, increasing the refrigeration load of the air conditioner, and it is very likely that the refrigeration effect is not good.

5.It is also possible that the air conditioner lacks refrigerant, you can check it, and if it is lacking, add fluoride in time.

6.In addition, if the air outlet of your home is not large, this is the air filter has a lot of dust accumulation, blocking the air circulation, so that the refrigeration capacity in the machine can not be brought out by the flowing air in time, resulting in insufficient refrigeration capacity. The filter should be cleaned to return to normal.

The reason why AUX air conditioning and refrigeration are not good: the indoor and outdoor units are too dirty, and the filter screen and finned aluminum foil heat sink are gray and dusty; The fan speed is too slow, the motor itself is not good, and the capacitance capacity is reduced; There is a blockage in the system pipeline; The outdoor unit is not installed in a good position, and at the same time, the heat dissipation is poor, and it is directly exposed to the sun for a long time; The power supply is unstable or too low. Workaround:

Cleaning the exterior of the air conditioner; Add air conditioning refrigerant; Clean the pipes and tidy up the air conditioning lines; Make a baffle to isolate direct sunlight; Ask the repairman to check the power supply. Expand the information of the Yanshan Exhibition: the daily use and maintenance of air conditioners:

The temperature can be set appropriately, because when the air conditioner is cooling, if the indoor temperature and the outdoor temperature difference is too large, it is easy to make people get "air conditioning disease", it is recommended that the air conditioner can be set at an acceptable temperature when it is used. When the air conditioner is cooling, the position of the wind deflector is adjusted to the horizontal direction, and the cooling effect will be better. Keep the air outlets smooth and don't pile up bulky furniture to block air circulation.

Unplug the air conditioner when not in use for a long time, as the standby state will also consume power. Do not place heavy objects on the outdoor unit. There should be no shelter around the outdoor unit.

Before restarting the machine, carefully check whether the drain pipe of the indoor unit is blocked by debris to prevent the phenomenon of stagnant water backfilling. Use a separate socket and cannot be shared with other electrical appliances; Do not change the operating status of the air conditioner while the machine is running. The indoor air inlet filter should be cleaned every 15 days, and the outdoor unit should be dusted regularly.

When the air conditioner is not in use or in case of thunderstorms, the power supply of the air conditioner should be cut off in time to avoid machine failure caused by power connection.

There could be the following reasons:

1.The air conditioner filter needs to be cleaned or replaced, resulting in insufficient air flow and affecting the refrigeration effect.

2.The radiator of the outdoor unit or indoor unit of the air conditioner is covered with dust or debris, which affects the heat dissipation effect and leads to poor cooling effect.

3.There is fluorine leakage or insufficient refrigerant in the dismantling road of the air conditioning refrigeration pipe, resulting in poor refrigeration effect.

4.The outdoor temperature of the air conditioner is too high, which exceeds the cooling range of the air conditioner, resulting in poor cooling effect.

5.The indoor temperature of the air conditioner is too low, which exceeds the cooling range of the air conditioner, resulting in poor cooling effect.

If none of the above methods can solve the problem, it is recommended to contact a professional air conditioner maintenance personnel for inspection and repair.

A leak detector is needed to find out if there is a problem with the refrigerant line, and sufficient refrigeration dose is sufficient after repair. If the compressor has poor working performance, the compressor of the same specification should be replaced to take lead. For other reasons, it is recommended to contact a professional repairer for maintenance.

Reasons for this:

If the refrigerant is insufficient, make up the refrigeration dose according to the regulations, and use a leak detector to find out the leakage of the refrigerant pipeline, sufficient refrigeration dose after repair, and then clean the air filter, remember to replace the capillary tube or filter drier, check whether the compressor discharge pressure is normal, if the compressor has poor working performance, the compressor of the same specification should be replaced, the surface ash of the condenser is too thick, and the condensation heat dissipation effect is poor, resulting in the increase of the exhaust pressure and exhaust temperature of the compressor, so that the refrigeration capacity decreases, the ash on the surface area of the condenser is removed, and the refrigerant is overchargedWhen the working environment temperature of the outdoor unit is too high, the condensing pressure and temperature are too high, so that the refrigeration capacity decreases, and the working environment temperature is changed. This is the most convenient and quick way to do it, remember.

There are various reasons why an air conditioner does not refrigerate:

1. The air conditioning mode is set on ventilation.

2. The starting capacitor of the external compressor is broken.

3. The air-conditioning and refrigeration system lacks refrigerant (freon).

4. The tube temperature sensor of the evaporator of the internal machine is broken.

Turn the air conditioner for 30 minutes (the refrigerant is evenly distributed in the system), see whether the connecting pipe of the external unit is condensed or frosted, and whether the connecting pipe is cold with a hand mold.

The condensation of the connecting pipe of the external unit is normal. Frost is a lack of snow.

The die connection tube is cold and feels normal. The opposite is abnormal.

For details, please call us or make an appointment for maintenance.

The frosting of the thin tube proves that the ice type of the air conditioner is not enough, and also pay attention to the capacitance of the air conditioner.

It's obviously a lack of refrigerant.

If you can't add it, don't add it!
