DEHUMIDIFIERS

Dehumidifiers, can generally be divided into two categories: civil dehumidifiers and industrial dehumidifiers, which are part of the air-conditioning family. Generally, a conventional dehumidifier is composed of a compressor, a heat exchanger, a fan, a water container, a casing, and a controller.

The working principle is: the humid air is drawn into the machine by the fan, and the heat exchanger is used, and the water molecules in the air are condensed into water droplets, and the dried air after the treatment is discharged outside the machine, so that the indoor humidity is maintained at an appropriate level. Relative humidity.

The main production areas of global dehumidifiers are concentrated in Italy, Japan, China and other places, and China's position in the global dehumidifier market is increasingly prominent. In particular, industrial dehumidifiers are used in medicine, hospitals, electronics, computers, and food industries.

WORKING PRINCIPLE

Defrosting principle of refrigerating dehumidifier

When a compressor-type dehumidifier is used in a relatively low temperature environment (generally below 10 degrees Celsius), it will cause frosting in the dehumidifier heat exchange system, and this process is unavoidable, so the compressor-type dehumidifier is at ambient temperature. In the lower case, the defrosting state is periodically entered. At this time, the dehumidification machine stops the compressor work first, and uses the evaporator heating wire (part of the heat exchange system) to heat the heat exchange plate temperature, and then outputs the fan to produce a defrosting effect. This time-consuming needs to be determined by the ambient temperature. The lower the ambient temperature, the longer it takes. In the defrosting process, the compressor-type dehumidifier cannot perform the dehumidification work, so the compressor-type dehumidifier is dehumidified in the low temperature environment. The effect is not ideal. For a dehumidification environment with a low ambient temperature, a new rotary dehumidifier can be purchased.

How the rotary dehumidifier works

1.The dehumidification runner is made of ceramic fiber paper with a temperature resistance of 500 ° C or higher. After the honeycomb rotor is made through a molding machine, and then the silica gel is coated between the ceramic fibers, the dehumidification runner does not burn and Delilysis and other issues. Since its dehumidification function utilizes physical rather than chemical action, it does not produce any harmful chemicals.

2. The dehumidification principle of the rotary dehumidifier uses the silica gel coated on the runner to physically adsorb the moisture in the air onto the porous synthetic silica gel, and then adsorbs it on the silica gel in the regeneration zone of the runner. The water vapor of the hole is heated and vaporized to the inlet of the AC heat exchanger to form high-temperature and high-humidity air, and then the heat exchanger which has been cooled by the indoor cold and humid air is cooled, and the condensed water is discharged due to the difference in dew point.

MAIN TYPE

Refrigeration dehumidifier

1.1 According to the use of function points, can be divided into: general type, cooling type, temperature adjustment type, multi-function type.

The general type dehumidifier means that the air is cooled and dehumidified by the evaporator, and is heated by the reheater to reduce the relative humidity. The condensation heat of the refrigerant is completely taken away by the air flowing through the reheater, and the outlet air temperature cannot be adjusted. Dehumidifier for heating and dehumidification.

The cooling type dehumidifier means that on the basis of the general type dehumidifier, the condensation heat of the refrigerant is mostly carried away by the water-cooled or air-cooled condenser, and only a small part of the condensation heat is used to heat the air passing through the evaporator, which can be used for cooling. Dehumidifying dehumidifier.

The temperature-regulating dehumidifier refers to the condensation heat of the refrigerant can be taken away in whole or in part by the water-cooled or air-cooled condenser on the basis of the general type dehumidifier, and the remaining condensation heat is used to heat the air passing through the evaporator. Dehumidifiers with adjustable wind temperature.

The multi-functional dehumidifier refers to a dehumidifier that integrates three functions of temperature rising and dehumidifying (general type), cooling and dehumidifying, temperature adjusting and dehumidifying. In the absence of outdoor unit (air cooling) or cooling water (water cooling), temperature dehumidification can be selected. A dehumidifier that functions to dehumidify.

1.2 According to the presence or absence of the fan, it can be divided into: conventional dehumidifier and air duct dehumidifier.

1.3 According to the structure, it can be divided into: integral, split, and overall mobile.

1.4 According to the applicable temperature range, it can be divided into: type A (common type 18 ~ 38 °C), type B (low temperature type 5 ~ 38 °C).

1.5 According to the method of returning the wind, it can be divided into: the hood with the hood, the back and the upper and the back.

1.6 According to the control form, it can be divided into: automatic type and non-automatic type.

1.7 According to the special use situation, there are also new wind type, explosion-proof type and so on.

Rotary dehumidifier

The main structure of the rotary dehumidifier is a continuously rotating honeycomb drying wheel. The dry runner is a key component for moisture absorption in the dehumidifier. It is composed of a corrugated medium made of a special composite heat-resistant material. The corrugated medium carries a moisture absorbent. This design is compact and provides a large surface area for adequate contact between wet air and moisture absorbing media. Thereby, the dehumidification efficiency of the dehumidifier is greatly improved.

Solution dehumidifier

The solution dehumidification air-conditioning system is a new air-conditioning product developed based on the active dehumidification air treatment technology that adjusts the air humidity with the dehumidification solution as the moisture absorber and the air temperature with the refrigerant as the refrigerant. The core of the solution is to use dehumidification. The physical properties of the agent, through the innovative solution dehumidification and regeneration method, to achieve efficient dehumidification above the dew point temperature. The system temperature adjustment is carried out completely in a normal-pressure open atmosphere. It has the technical features of simple manufacturing, reliable operation, energy saving and high efficiency. The system is mainly composed of four basic modules. They are the air supply (new air and return air) module, the humidity adjustment module, the temperature adjustment module and the solution regenerator module.

Pipe dehumidifier

The pipeline dehumidifier uses an evaporator to cool and dehumidify the air, and recovers the condensation heat of the system to make up for the heat lost in the air due to cooling and dehumidification. It is an energy-saving dehumidification method, which provides a kind of indoor and outdoor. Pipeline temperature regulation and humidity control method and equipment for heating, cooling and dehumidification indoors to meet indoor temperature and humidity requirements, pipeline dehumidification system mainly consists of cooling and dehumidification mode, temperature and dehumidification mode, temperature rising dehumidification mode, heating mode , automatic defrost composition.

Dehumidifiers are seasonal products. If they are used properly, they can reduce the failure rate and prolong the service life of the dehumidifier.

ways to properly use, maintain, and maintain your dehumidifier.

1. Correctly adjust the set humidity of the dehumidifier: When the user adjusts the set humidity of the dehumidifier, the humidity should be set according to the actual feelings such as the feeling of humidity, the number of people in the space, and the size of the space. Usually, in the state of less activity such as rest and sleep, the relative humidity of the room is around 60% RH, and the human body will feel more comfortable. The humidity setting is too low, except that it will make people feel dry. Because of the large difference in humidity between indoor and outdoor, the moisture is expanded faster, which causes the compressor to start and stop frequently, which shortens the service life of the dehumidifier and consumes more. More energy.

2. Regularly clean the dehumidifier: periodically remove the filter of the dehumidifier for cleaning, which can effectively improve the dedusting effect of the dehumidifier and improve the ambient air quality. Regularly cleaning the heat sink of the outdoor unit can effectively improve the heat transfer coefficient and heat exchange efficiency, and improve the working efficiency of the dehumidifier.

3. Regularly let the professional check the dehumidifier: After the long-term use of the dehumidifier, the electrical circuit and control components in the unit will have different degrees of aging, which will cause serious damage to the unit and the human body. Regularly let the professional dehumidifier The circuit is inspected, the aging components are replaced, and the refrigerant is replenished, which prevents the components from aging and harms the machine and the human body, and keeps the dehumidifier in a good working condition.

4. If the dehumidifier is not used for a long time, it should be protected. When the dehumidifier is not used for a long time in winter or outside, apply a protective cover to cover the dehumidifier to avoid sun, rain and dust deposition, which will cause difficulties in cleaning and maintenance in the future.

Automatic defrost

A. Computer-controlled automatic defrosting device: It adopts advanced computer control technology. It accurately senses the defrosting temperature and ensures that the machine can still operate normally in the environment as low as 5 °C. It is the most advanced and reliable automatic defrosting device for dehumidification. The machine has the ability to work "all-weather".

B. Mechanical temperature control defroster: Thermostat with metal memory chip, because the defrost temperature can not be accurately controlled, the defrost performance is not stable enough, and sometimes the machine can operate normally at around 8 °C, and some However, the frost is stopped at around 13 °C.

Therefore, this defrosting device is not accurate and reliable.

Note: Some Type A designed dehumidifiers install relays on the machine, stopping the compressor at regular intervals (the electric fan remains in continuous operation) waiting for the heat exchanger.
