What are the general features of a dehumidifier?

Cooling Dehumidification

Cools the air below the dew point and then removes the condensed moisture.

Effective where the dew point is above.

Dehumidification by compression

Compresses and cools humid air to separate the moisture.

Effective in small air volumes, but not suitable for large air volumes.

Solid adsorption dehumidification

The use of capillary action will be adsorbed in the solid hygroscopic agent.

Can reduce the dew point, but the adsorption area is large when the equipment also becomes large.

Liquid absorption dehumidification

The use of lithium chloride aqueous solution of spray absorption of moisture.

The dew point can be reduced to about but the equipment is large and the absorbing liquid must be replaced.

Adsorption rotor dehumidification

A thin sheet impregnated with a moisture absorber is machined into a honeycomb rotor for ventilation.

Its dehumidification structure is simple, and the dew point can reach below -70℃ after special grouping.

Suitable range of dehumidification

Principle of air treatment

Continuous supply of dry air. Air treatment is a high-performance dry dehumidifier using a cellular dehumidifying rotor.

Air Treatment's honeycomb rotor continuously repeats the hygroscopic regeneration action as it rotates, providing dry air with an ultra-low dew point on a continuous basis without interrupting the air flow.

Honeycomb type rotor

Kindred's dehumidifier rotor adopts Japan NICHIAS high-efficiency ceramic silicone rotor. Ensure that the dehumidifier rotor passes through the large air volume but firmly does not shed dust. Japan NICHIAS high-efficiency ceramic silica runner is a ceramic base material and silica mixed sintered into a honeycomb cylinder precision cutting and become, the whole runner is a highly efficient moisture absorption body, can handle 100% wet air and does not fall off, not deformed. The service life can be up to 10 years or more, can be cleaned many times, the life is very long.

Basic Structure of Air Treatment

Dehumidification Principle of Air Treatment

The system adopts a honeycomb dehumidification rotor as shown in the figure. The drive motor makes the dehumidification rotor rotate 8~18 times per hour to repeat the action of humidification and regeneration continuously, thus providing dry air.

The rotor is divided into a moisture absorption zone and a regeneration zone. After the moisture in the air is removed in the hygroscopic area, the blower sends the dried air into the room.

The absorbed moisture moves to the regeneration zone, where regeneration air (warm air) from the opposite direction drives out the moisture and allows the rotor to continue working.

The regeneration air is heated by a variety of devices such as steam, natural gas, gas, gas, oil, and electricity.

Due to the special performance of Japanese NICHIAS high efficiency ceramic silica rotor and zeolite rotor, the Kindred series of dehumidifiers can continuously dehumidify the air under a large air volume and can achieve very low moisture content requirements. After the matching combination, the moisture content of the treated air can be lower than 0.0007g/kg

If you want the temperature of the dry air to remain stable, you can cool or heat the air at the outlet of the dehumidifier by installing a cooling device or a heater.

Characteristics of air treatment

During the production process of products, the annoyance caused by moisture to the products is always bothering human beings. The application of solid adsorbent for moisture absorption process synchronized with the adsorbent after moisture absorption regeneration and dehydration treatment, so that the solid adsorbent recycling, the entire moisture absorption work can be carried out continuously. Overcome the static solid adsorption can not be continuous dehumidification and refrigeration condensation dehumidification in low temperature and low humidity can not help the shortcomings. Can play its low-temperature and low-humidity conditions can be continuous and stable, large dehumidification characteristics. Jindry company's rotary dehumidifier is the application of this advanced technology developed, with special features that can not be. The rotary dehumidifier, compared with other dehumidification methods, has its own unique characteristics;

It can simply obtain dry air with ultra-low humidity.

It can continuously provide dry air with ultra-low humidity with dew point below 6℃, which cannot be realized by cooling dehumidification method, at low cost.

Simple operation and maintenance.

The structure is simple, and the drive unit is simple, so it is easy to operate because dry air can be obtained by running only the dehumidifying rotor, regeneration heater, and blower. In addition, it is a dry dehumidification type that does not need to be replenished with hygroscopic agent, so it is easy to maintain, and the cost of operation and maintenance is low.

Superior durability.

In a clean air environment, the performance of the dehumidifying rotor will hardly decline or degrade, and can be capable of continuous operation for years.

A wide range of machines.

We have a wide range of machines that are suitable for a variety of conditions, from standard models for general use to low-humidity models that produce dry air with ultra-low humidity.

Harmless green machine due to the use of ceramic silica and zeolite rotor for non-toxic odorless green hygroscopic agent, so the dehumidifier in the use of the process of safety, environmental protection, clean, no fugitive dust and corrosion-free, but also sterilized, pharmaceutical, food, biochemical and other industries is particularly suitable.

Air conditioners should not be used instead of dehumidifiers

Many users ask: "Air conditioners can not also dehumidify? With air conditioning, dehumidifier is not superfluous?" In fact, this is a consumer misconception, the main function of the air conditioning unit is cooling and heating, with independent dehumidification function of the air conditioning unit can be dehumidified, but the amount of dehumidification is small, dehumidification is slow; and in the southern region of the rainy season, the temperature is low, most of the time in the 20 ° C or less, this time the air conditioner dehumidification blowing out the cold wind, the more dehumidification is the colder, the more uncomfortable feeling to the person. In addition, because the air conditioner is fixed only in a small local area range of dehumidification, more importantly, when the air wither machine dehumidification increased several times the load running, not only power consumption, but also make the compressor damage, shorten the life of the machine. Therefore, air conditioners should not be used instead of dehumidifiers.

Principle and use of dehumidifiers

Dehumidifier by the compressor, heat exchanger, fan, water container, housing and controller, its working principle is: the fan will be humid air pumped into the machine, through the heat exchanger, the moisture in the air at this point in time condensed into water droplets into a dry air discharged out of the machine, and so on, so the cycle of indoor humidity is reduced.

Therefore, dehumidifiers are widely used in laboratories, computer rooms, measurement rooms, libraries, archives, offices, instrumentation rooms, hospitals, power distribution, banks, material reserves, food and crop warehouses, etc., so that electronic products, optical instruments, precision equipment and valuables to avoid the bad luck of moisture, mold.

In recent years, as the people's living standards continue to improve, people's consumerism is updated, dehumidifiers have gradually entered the family, becoming an indispensable member of many families. Especially in the rainy season, they have become a high-grade clothing and leather goods, high-grade household appliances, the God of protection, into the rheumatism, respiratory and other diseases of patients and the elderly, mothers and infants and children's health care workers, for all the need for appropriate humidity to create a good environment for the user.

House area set dehumidifier reference

General building (room height of 2.3 meters, doors, windows closed normal ground building), the room area set dehumidifier reference: dehumidification 20 liters / day area of 20 square meters ~ 30 square meters or so; dehumidification weight 30 liters / day area of 30 square meters ~ 40 square meters or so; dehumidification 50 liters / day area of 50 square meters ~ 70 square meters. Day for an area of 50 square meters ~ 70 square meters or so; dehumidification weight of 90 liters / day for an area of 100 square meters ~ 150 square meters or so.

Note: the relative humidity requirements of the family and office space can generally configure 20 liters / day ~ 30 liters / day of dehumidifier, and can take turns to ask each room dehumidification; the relative dehumidification requirements of high valuables place should be fixed configuration of the corresponding number of machines.

Notes on the use of dehumidifiers and maintenance methods

Condenser should be cleaned from time to time to keep clean. Dehumidifier should be placed in the center of the room. The air inlet and outlet of the dehumidifier should not be blocked by obstacles, and the air filter should be cleaned. Around the temperature is lower than 15 ℃, attached to the evaporator surface of the water droplets will freeze and make the dehumidifier effect is weakened, if the surrounding temperature is more than 40 ℃ or more, the pressure in the system will increase and make the compressor overload, this time the overload protector should be cut off the line, otherwise the compressor motor will be destroyed. So the best use of dehumidifier temperature range of 15 ℃ ~ 40 ℃. If the humidity in the air is below 30%, it is too dry and uncomfortable, so the reliable humidity controller should be controlled to maintain the range of 50% to 60%. When in use, windows and doors should be closed as much as possible to achieve the dehumidifying effect in the room. The machine body should be placed flat, not tilted or horizontal fall, to avoid machine failure or abnormal noise.

The best way to move a dehumidifier is to leave it in place for four to six hours before turning it on, because the compressor line in the dehumidifier contains cold coal, and the cold coal must return to its original position after four to six hours of moving. Clean the air filter regularly (about once every two weeks) to maintain the dehumidification, dust removal efficiency and life of the machine. Cleaning the air filter can be done with water below 40℃; it is better to clean it with detergent, wash off the dust, rinse it with water, dry it in the shade and put it back into the machine. When cleaning the body, use a wet cloth to gently wipe; avoid directly splashing water to clean up, so as not to damage the electrical insulation. If there is any adhesive on the surface of the body, use soapy water to clean it, avoid spraying it with gasoline, petroleum spirit, solvents or aerosol insecticides to avoid paint peeling or discoloration. Do not use a thin rod or wire to pull out the inside of the machine to avoid malfunction or danger. Please unplug the power cord to maintain the life of the machine when it is out of power or not in use for a long time, or when you are traveling.
