What problems can be caused by dirty air conditioner filters?

1. Poor refrigeration and heating effect of air conditioning: the filter screen is dirty and blocked, the temperature of the indoor unit air outlet is very low during refrigeration, but the air blowing is not far away, the room circulation is slow, the temperature around the indoor unit is low, and the temperature in the room is high, which is similar to the slow speed of the fan.

2. Plugging the water tray (cabinet machine, hanging machine) The filter screen is dirty and blocked, and the dust gathers on the surface of the evaporator through the gap, and flows into the water tray with the condensate.

3. Blockage of the evaporator (cabinet machine): If the barber shop uses a cabinet machine, the filter screen is dirty and blocked, and the hair is sucked in by the fan and blown to the back of the evaporator, causing the evaporator to be dirty and blocked, even if the filter screen is cleaned, the evaporator needs to be cleaned; If the cabinet is used in a public place in winter, the dust is easily sucked in by the fan and blown to the back of the evaporator, which will also clog the evaporator.

4. Blocking the fan blades (cabinet machine, hang-up) Dust blocks the filter screen, the fan motor runs, the dust adheres to the blades, the spacing becomes smaller, the blowing volume becomes smaller, and the noise will become larger, and the air volume of the air outlet is unstable.

5. Heating overload and non-defrosting: the filter screen is dirty and blocked, the surface temperature of the evaporator is too high during heating, the heating time becomes longer after the motherboard is detected, the condenser is seriously frosted, and the outdoor fan is controlled to stop at the same time.

6. Refrigeration icing: the filter screen is dirty and blocked, the evaporator temperature is very low during refrigeration, and the motherboard enters the refrigeration anti-icing protection after detection, controls the shutdown, and no longer refrigerates.

7. Water leakage of indoor unit: the filter screen is dirty and blocked, and the temperature of the evaporator is very low during refrigeration, if the motherboard is not equipped with refrigeration and anti-icing protection, the evaporator will freeze and the indoor unit will leak.

I hope you can clean the air conditioner filter more to avoid the above problems.

Yes! The dirty filters of the internal and external units of the air conditioner will block the air circulation! There are many times when maintenance personnel say that they are deficient in fluoride in order to make more money! They all cause low voltage alarms!

1. If the air conditioner filter is dirty but not cleaned in time, the dust on the filter screen may gather on the surface of the evaporator along the gap, and then flow into the water tray with the condensate.

2. If the air conditioner filter is dirty but not cleaned in time, the dust on the filter screen may enter the back of the evaporator with the fan, causing the evaporator to be blocked, resulting in water leakage of the indoor unit.

3. If the air conditioner filter is dirty but not cleaned in time, the owner turns on the air conditioner, the fan motor will start running, and the dust may slowly gather on the fan motor blades, which will make the spacing of the blades smaller, the blowing volume will be smaller, and it will make a loud noise.

4. If the air conditioner filter is dirty but not cleaned in time, if the air conditioning refrigeration function is turned on, the air temperature blown out of the indoor unit will be very low, but it will not blow far, which will lead to the phenomenon that the temperature near the air conditioner is low and the temperature of the whole room is very high.

How often should the air conditioner filter be cleaned.

1. Household air conditioners, if they are not in areas with more oil smoke or large wind and sand, it is best to clean the filter once after 300 hours of air conditioning. If it is in an area with a lot of oil smoke or sand, the air conditioner should be cleaned once after 100 hours of use.

2. When cleaning the air conditioner filter, first open the front cover of the air conditioner, then pick both sides of the panel, and pull it open hard to see the filter, the filter screen is without screws, so it is easy to take it off.

3. The filter screen can be cleaned with clean water or a hair dryer, pay attention to the small intensity when cleaning, otherwise it is easy to damage the filter. After washing, let it dry in the shade.

Reasonable use of air conditioners:

Some users flush the baffle of the air conditioner in the process of using the air conditioner, but because the heat is rising, it is easy to cause the indoor temperature to not meet the standard. However, if the air conditioner comes with its own thermostat, the air conditioner will automatically shut down because the ambient temperature of the air conditioner reaches the set standard.

The air-conditioned room should not have too many people, otherwise the cooling capacity will be insufficient, and the temperature will be difficult to drop. Do not open and close the doors and windows of the room frequently, and do not enter and exit frequently, so as not to lose the air conditioner. The glass windows must be closed tightly, and double white curtains should be hung inside to reflect some of the light and heat.

When the room is ventilated, the window can be opened for a short time, and the window opening time is generally not more than 10 minutes.

<> if the air conditioning filter is dirty, it will affect the air conditioning refrigeration, under normal circumstances, if the air conditioning filter is dirty, the air conditioner may stop running, which will lead to the phenomenon that the air conditioner is not refrigerated, and it may also cause the water of the air conditioner to not be discharged, so the air conditioning filter needs to be cleaned in time if it is dirty.

This answer is suitable for most brands of air conditioner models such as Chigo, Haier, Oaks, etc.

This indicates that the system has detected that the filter is dirty.

Further reading: Air conditioner cleaning: Clean the filter directly, then unplug the power and restart it.

Cleaning the filter:

When cleaning the air conditioner filter, the power cord of the air conditioner should be unplugged first to fully ensure safety;

Lift the air conditioner panel and lift it, then we can see the air conditioner filter, then remove the air conditioner filter;

When removing the air conditioner filter for cleaning, if there is not much dust on the filter, you can rinse it directly with clean water, but be careful not to rinse the dusty side, and do not use dish soap with strong acids and alkalis. If a lot of dust has accumulated on the filter screen, you can soak the filter screen in a solution of neutral detergent;

After cleaning the filter screen, the water on the filter screen should be dried, and at the same time, it should be dried in a cool and ventilated place, but it should not be directly exposed to the sun;

When putting the filter back into the air conditioner, you need to wipe the inside of the air conditioner again, so that it will be cleaner when you use it again.

The dirty blockage of the air conditioner is caused by the dirty things entering the air conditioner, and after the dirty blockage occurs, it will affect the refrigeration function of the air conditioner, even if the refrigerant is added, it cannot be solved. If dirty blockage occurs, be sure to clean and dry the inside of the pipe in time. So what happens when the air conditioner is dirty?

The air conditioner is generally blocked by blowing natural wind, not refrigerating, the pressure is too high, the current is too large, some copper pipes are frosted, and they do not return to normal after heating, the compressor working sound is low and muffled, there is a sound of wind transmission, the outdoor heat exchanger is not hot, there is no warmth, the indoor heat exchanger is frost-free, the air conditioner is protected by high pressure for a period of time, and it is restarted after the pressure is equalized, and it is repeated and non-stop.

The formation of dirty blockage is caused by excessive impurities in the refrigeration system. For example, dust and metal debris in the manufacturing process of refrigeration systems, and the oxide layer on the inner wall of the pipe is peeled off when the pipe is welded; During the processing process, the inner and outer surfaces of the parts are not cleaned, the pipeline is not tightly sealed, and dust enters the pipeline; Refrigeration oil and refrigerant desiccant filters contain impurities and inferior desiccant powder; In addition, it is easy to weld the expansion valve nozzle when welding the expansion valve and filter drior.

After starting, if the evaporator can be cooled for a short time, and then the refrigeration function disappears, this is an ice blockage. However, after the dirty plug is filled with refrigerant, it will not be refrigerated at any time.

In other words, the ice can be refrigerated after a period of time, forming a periodic repetition of blocking, closing, clogging, and blocking. When a blockage occurs, it cannot be refrigerated.
