What happens when an evaporative cooling fan heats up?

If it is a high-frequency vibration, it is the lack of water in the water tank or the lack of water that causes the pump to dry up; It is also possible that the impeller of the water pump is damaged, resulting in polarization, but the probability is too low;

If there is a sound of water, it is likely that the return hose has fallen off, or the floating mat is hanging on the bottom (if there is a floating mat), in short, the backwater is directly low on the water surface and makes a sound.

In short, if it only sounds when it is refrigerated, it is likely to be a problem with the water pump or the sound of falling water. Now the cooling fan on the market can be called evaporative cooling fan, that is, the ice crystal box is put into the refrigerator in advance and then put it into the water storage tank of the cold fan, so that the water temperature is reduced, and the water in the water tank is continuously pumped out with a circulating water pump, and evenly sprayed on the evaporation filter layer through the water distribution system, and the fan blows the cooled air into the room.

A cooling fan does not cool down because the frozen ice crystal box absorbs the heat from the air.

At present, mainstream manufacturers, Midea, Gree, Emmet, Haier ......Both have cooling fans.

The main point of the cooling fan is that it does not need to be installed and can be moved freely, unlike the air conditioner, which requires an indoor unit and an outdoor unit, and the installation is complex, because it cannot be refrigerated, the cooling effect is limited.

Of course, the cooling fan is also very cheap!

The modulation effect is very good, but if your Gree air conditioner will make a relatively loud noise when it heats up, it may be.

Failures that occur. One is that the reason for the fixed frequency of the compressor of the air conditioner itself is that the sound is louder than the sound of frequency conversion, and the other one.

One reason is that the temperature of the air conditioner is too large and the distance between the indoor temperature is too large, so it is recommended that the user first debug a lower temperature.

Wait for the temperature to go up, and then adjust the next temperature. The quality of Gree air conditioners is generally good, but if there is a failure, we should also deal with it immediately.

1. The wet curtain part is not wet during refrigeration.

Solution: It may be that the water distributor of the air conditioner is blocked, and it can be dredged and cleaned; Or there is no installation level, and the pad must be level.

2. The wet curtain is not wet during refrigeration (the hand control display is normal).

Solution: Check whether the water distributor and the water supply pipe of the distributor are blocked, whether the water inlet of the water pump is blocked, and check whether the water pump is working normally.

3. The refrigeration icon on the handset flashes.

Solution: This information indicates that the water level of the chassis in the machine is not enough, check whether the water inlet pipe valve is closed, the water inlet valve is blocked, or whether the water is stopped. If the water level of the chassis is normal, but it still shows a water shortage fault, it is a water level probe fault.

4. Water leakage. Solution: a. Water inlet pipe leakage: the metal pipe is damaged or there is no sealing ring. Replacement is possible.

b. Water leakage from the overflow port of the drain valve: At this time, the water level is high, and the float of the inlet valve needs to be lowered.

c. Leakage of side panels: If there are foreign objects left on the wet curtain, they can be removed

Summary. Cold storage failure (1) Fault phenomenon: insufficient air volume and wind pressure Cause of failure:

1. Air duct leakage 2, system resistance, local blockage 3, conveyor belt slippage or break 4, motor speed reduction 5, loose fit between the electric blade and the shaft 6, wrong direction of rotation (newly installed fan) Elimination method: 1. Block the air leakage 2, clear the blockage 3, replace the conveyor belt 4, check the power supply voltage or other reasons of the motor 5, check the loose cause for treatment 6, check and adjust the direction of rotation of the cold storage fault (2) Fault phenomenon: impeller damage or deformation fault cause:

1. Loose blade fixing bolts or rivets are loose, corrosion falls off 2. Bearing wear, scenery shaft deviation, serious friction between the impeller and the shell (touching the shell) 3. Hard debris such as stones falling into the impeller Eliminate the blade: 1. Clean the bearing, add lubricating grease 2, repair the deformed blade, replace the bearing 3, clean up the debris, and repair the deformed blade.

Cold storage failure (3) Fault phenomenon: bearing overheating or stuck fault causes: 1, the bearing lacks lubricating grease 2, the working life of the roller bearing has reached 3, the bearing is not well installed or the fan shaft and the motor are not concentric, the bearing is eccentric 4, the bearing is scraped and grinded, and the installation clearance is too small to eliminate the method

1. Qingsen dresses up the bearing, adds lubricating grease 2, updates the new bearing 3, adjusts the concentricity of the motor and fan shaft 4, re-scrapes the bearing, adjusts the gap between the shaft and the bearing bearing, and the Shichun cold storage fault (4) Fault phenomenon: the cause of the irregular vibration failure of the fan: 1.

Evaporative cooling fans are a more efficient and environmentally friendly home appliance than traditional fans, but they also have some common faults. Here are some common faults and their possible causes: Cooling fan won't start or shut down:

This can be caused by a faulty power supply, a loose plug, or a faulty internal circuit of the fan. You need to check whether the power cord is plugged in tightly, whether the power supply is normal, and whether the internal circuit of the cooling fan is damaged. The cold fan becomes louder or unusual

This can be caused by worn motor bearings, deformed fan blades, or an unbalanced fan base. It is necessary to check whether the motor bearings need to be replaced, whether the fan blades are damaged or deformed, and whether the base is stable. Leaking water tank:

This can be caused by a poor tank seal, a broken tank, or a loose connection pipe. It is necessary to check whether the tank is well sealed, whether the tank is damaged and the connecting pipe is tight. The water pump is not working:

This can be caused by a damaged water pump, loose connection lines, or a blocked water pump. It is necessary to check that the pump is functioning properly, that the connection lines are tight, and that the pump is not blocked. The filter element needs to be replaced

The filter element is an important component of the Kobu Chigishu within the cooling fan, which can help purify the air and keep the water tank clean. If the filter becomes dirty or expired, it may affect the performance and effectiveness of the cooling fan. Filter cartridges need to be replaced regularly according to the instructions for use.

The above are some common faults and possible causes of evaporative cooling fans, if you have problems with your cooling fan, it is recommended that you refer to the above content to troubleshoot. If it cannot be solved, it is recommended that you contact the after-sales service center for repair.
