Refrigerated dehumidifierThe principle of cooling with compression mechanisms is dewetting, with water in the air entering the thermal exchanger to condensate, and then accumulates and drops out and discharges into the water vent. The dehumidifiers are not the same as the air conditioners. The main function of air conditioners is to cool and heat, and air conditioners with independent dehumidifiers can dewet, but with small dewetting and slow dewetting. Also, during the rainy season in the southern region, the temperature is not high, and it would be rather uncomfortable to dehumidize with air conditioning, when cold winds are blowing out, and when dehumidified, the colder it gets. The air conditioners are in fixed positions and can be dehumidised only in small local areas, while long dehumidization of air conditioners increases the load of compressors, which not only consumes large amounts of electricity, but also can easily damage the compressors and reduce the lifetime of the whole machines. Therefore, air conditioners are not suitable to replace the dehumidifiers. The dehumidifier is internal cooling within the machine, excreting the water from the air, but the temperature is slightly higher in space, but the temperature differentials are less visible and more applicable to the four seasons, and electricity use is saved.

Theoretically, the air passes through the condensing tube, making it cold. But the dehumidifiers themselves operate to produce heat. The temperature in the air is not excreted, so it's still indoors. It's not like the air conditioner takes heat out of the room and the heat from the machine's operation makes it hot. Most of the dehumidifiers use semiconductor systems to force water vapour condensation in the air. There is a special semiconductor material, called thermal exchanger, which becomes cold on one side and hot on the other, which is used in the dehumidifier. After the wind machine blew the wet air over the cold surface of the heat exchanger, the water vapour was condensed and the air moisture was reduced, thus achieving the purpose of the wetting. This is when the dehumidized air is imported into thermal surfaces to enforce the heat exchanger ' s cooling and take the heat from the heat exchanger. The dehumidifier would then work long hours without burning. The air in the vents is the cold heat exchanger, so it's hot. The dehumidifier has a hot wind in the vent, which can be equivalent to a drying agent. Indoors are more humid, driven by hot winds, which are more conducive to the drying of indoor air and can have the effect of drying. In the rainy season, or in cold winters, the laundry is difficult to dry, and the use of a wet-dehumid machine can evaporate the water molecules above the clothing, dry the clothes, and make them fragrance. Wet-deficit machines are by definition used to dewet rather than to cool rooms, and during their operation, vent heat is a normal feature of the operation of the machine, with a low humidity relative to the winter and a marked decrease in the temperature of the vent.

When the dehumidifier is used in a relatively low temperature environment, it is usually at below 18°C, causing thermal exchange system of the dehumid machine to frost, a process that is inevitable, so the dehumidifier is regularly defrosted at lower ambient temperatures. The compressor work is then stopped on the dehumidifier. This time-consuming process is determined by ambient temperature, the lower the ambient temperature, the longer it takes, and during the frosting process, the dehumidifier is not able to perform wetting, so that the dehumidifier does not have the desired dehumidification effect in lower temperatures. New types of wheeled dehumidifiers can be selected for use in dehumidizing environments with lower ambient temperatures.

Attention: When the dehumidifier works in winter, because the temperature of the room is below 18°C, the evaporation unit surface is less hot, it is frosted on the evaporation unit ' s surface, ice is frozen, the machine is automated for some time, if the machine does not automulgate the temperature sensors within the machine, when the machine is shut down, the ice inside the machine is drained through naturalized frost and water is drained out of the machine.There was a misunderstanding about the dehumidifier ' s defrosting principle, and there was a mistake to assume that the windows on the house wall were all frosted and that the defrosting machine was used to defrost the home, which was supposed to have the effect of defrosting the house. This is due to a lack of understanding of the principles of dehumidifiers. The dehumidifier has the same frost-freezing function as the air conditioner, and only means that it automatically removes the frost when it is removed from the inside of the machine.

& nbsp; 1, Wind-in: Whether or not the vent filter is blocked is a very common factor, which, when the wind is blocked, impedes the wind circulation of the dehumidifier, has a very poor humid effect and is often accompanied by a greater sound of the dehumidifier. Wind-in systems include condensers and evaporationers, and if there is dirt in the condensers and evaporationers, the circulation of wind is hampered (especially in the case of dusty, air-smuggling and harsh environments and sites, which is common); and winders themselves cannot have dirty sludge, which would otherwise lead to reduced wind flow.

2. Humidity set: As you know, most of the dehumidifiers are now fully automated, when we find that the dehumidifiers are not working well and work is often stopped, it is likely that we set the humidity too high and need to reconcile the moisture values.

3. Place: The position of the dehumidifier is also important, it is inappropriately located, and it affects the dehumidifier ' s dehumidisation effects, such as whether the dehumidifier is blocked by any barrier before entering the vent and whether the place is in favour of the air cycle (e.g., if the dehumidifier is not placed by the door, it should be placed as far as possible in the middle of the air in which it is not airy).

4. Sealed dehumidifiers are the most effective for the use of damp protection in a well-sealed environment, and if the site and the environment are not well sealed, this can lead to a deterioration in dehumidification, as the humid air from the outside continues to infiltrate the site where our dehumidifiers are used.

Temperature environment: Are the temperatures in the sites where we use the dehumidifiers very low? If the temperature is lower in the site and is below 18°C, the dehumidifier will have a much smaller dehumidity than the environment at 30°C and will have a freezing effect, resulting in the dehumidifier not dehumidizing, which will have little effect. In low-temperature environments, measures to increase ambient temperature can be introduced to enhance the dehumidification effect of dehumidifiers. In particular, it is cautioned that normal work cannot be performed if ambient temperature requirements are below 5°C or above 38°C.

6 Wet-dehumidifier type: We're oversized, too small, so we can have “ the mini-mara ” the dehumidity effect will be poor or less than what we want.

7 Sources of humidity: Are there a large number of sources of moisture in our sites, such as water flowing to the site in the water pump room environment with a dehumidifier, and evaporation of the water will result in increased humidity in our water pump room, which is what we call a source of moisture, which will continue to produce. This is a factor that needs to be taken into account in selecting the dehumidifier, and if it is small, it may result in the poor effect of the dehumidifier.

8- Outflow systems: to see whether we have ventilation and new wind systems in our workspaces for wet-deficit machines, because of the constant exchange of air in our wet-deficit airports by new winds, the external humid air is added to the air, which leads to an undesirable effect on the dehumidifiers, a situation that is common in the environment where central air conditioners are installed.

Fluorinated fluorine or refrigerants are insufficient, and fluorine leaking from wet-deficit machines is also a factor affecting the dewetting effect of wet-deficit machines.

Attention and maintenance methods for the use of wet-deductible machines:

1: The condensers should be cleaned and kept clean from time to time.

2: The dehumidifier shall be placed in the centre of the room. Access to and out of the wet machine shall be blocked by no barrier, the filter shall be cleaned, the water droplets attached to the evaporation unit ' s surface at temperatures below 18°C shall freeze and the dehumidifier ' s effect shall be reduced, and if the surrounding temperature exceeds 38°C, the pressure in the system shall be increased and the compressor overloaded, at which time the overloader shall be cut off, otherwise the compressor motor shall be destroyed. So the optimal temperature range for the dehumidifier is 5°C-35°C. If the humidity in the air is less than 30%, it is too dry and uncomfortable, so it can be controlled by a moisture controller, which can be maintained between 50% and 60%.

3: When used, doors and windows are closed to the extent possible to enhance the use of the dehumidifier. The body shall be placed flat and shall not be tilted or rolled to avoid a malfunction of the machine, and the dehumidifier shall be removed from the source and the water in the drum shall be poured out.

4: It is advisable to leave the dehumidifier two to three hours in silence before it can be used, since the compressor and copper tubes in the dehumidifier contain refrigerants, which after being moved take two to three hours to return to their place of origin.

5: The regular cleaning of the filters (approximately once a week every two weeks) to maintain the machine ' s air intake and to ensure the dehumidisation effect and to extend the machine ' s life. Cleaning of the filtration network is washed with water up to 40°C: cleaners are better, dust is washed, water is washed, and dry is put back into the machine.

6: Cleaning the body with a wet cloth and light-wielding is sufficient, no direct water washing is allowed, electrical circuits are avoided, glues on the surface of the body can be washed with soap water and no petrol, solvents, etc., can be used to avoid paint stripping or colour change.

7: No bar or wire may be used to remove the inside of the machine to avoid malfunction or danger. 8: Power is to be removed when power is out or away for long periods of time.  

1. The failure code indicates that:

(1) Machine display E1, usually temperature sensor failure

(2) Machine display E2, usually wet sensor failure

(3) The machine displays E3 and most of the reasons for its occurrence are either the compressor's activation of the capacitor failure or the refrigerant leak (in a few cases the sensor failure), the failure code is not immediately visible and usually comes on in 10 minutes. (Note: 380V voltage machines have no compressor capacitors, and in the case of E3 refrigerants are more leaking)

(4) Machine displays E4 and the problem often arises with the spectroscopy (a machine with a 380V voltage)

DY-6138EB shows that E4 is mostly a pasta problem.

2. Common phenomena of sensor failure:

(1) The number of the machine display screens - 1, 2, -9 and the temperature humidity sensor is likely to fail;

(2) The machine display screen displays 50 and cannot regulate the humidity up and down, often due to the malfunctioning of the humidity sensor;

(3) The machine display screen is always shown 99, often due to the failure of the humidity sensor.

Three, full of lights:

(1) Water tanks are placed in place;

(2) It may be that the floats in the water tank are stuck and that they can be moved, and if they are not stuck, they are basically water level switches that fail.
