It is well known that the rotary dehumidifier and humidity control system of cold storage have high requirements on temperature and humidity for the storage of many products. Some products need to be placed in a low temperature and humidity environment at 2-8 ℃, while some products need to be placed in an environment with lower temperature and humidity, such as:
1. The general temperature of the drug warehouse cold storage is 2-8 ℃, and the humidity is required to be 35% RH-75% RH
2. The general temperature of the food warehouse cold storage is 2-8 ℃, and the humidity is required to be about 55% RH
3. The temperature in the cold storage of seed warehouse is below - 18 ℃, the relative humidity in the cold storage should be lower than 50% RH, and the storage period is 50 years
Warehouse temperature - 4~0 ℃ The relative humidity in the warehouse is lower than 50% RH, and the storage period is 15 years
The storage temperature is 10 ℃, the relative humidity in the warehouse is lower than 75% RH, and the storage period is 3 years
Ordinary dehumidifiers are prone to frosting and have low energy efficiency, which cannot meet customers' needs, so (ZEDO) recommends low-temperature dehumidifiers or rotary dehumidifiers for cold storage, which can effectively dehumidify and meet customers' requirements for temperature and humidity
Model selection of dehumidifier in cold storage: the temperature environment of cold storage is 2 ℃ - 8 ℃, and ordinary dehumidifiers are used at 2-8 ℃, which is easy to frost and cause machine failure; Therefore, (ZEDO) suggests that the cold storage should choose the corresponding low-temperature dehumidifier or rotary dehumidifier to dehumidify, which can continuously dehumidify in a low temperature environment and quickly meet the humidity requirements in the cold storage
Generally, the rotary dehumidifier (ZEDO) is selected for low temperature cold storage, which can easily reduce the humidity to about 35% RH. When the humidity reaches the set value, the rotary dehumidifier will stand by, saving electricity costs. When the humidity value rises, the rotary dehumidifier will start to work again, which can fully and effectively ensure the humidity required by the environment
The dehumidifier runner of the (ZEDO) rotary dehumidifier moves 360 ° in a circular motion at a rate of 12-18rph in the box separating the dehumidifier zone and the regeneration zone. When the treated air to be dehumidified passes through the dehumidifier zone, the moisture absorption material in the dehumidifier runner absorbs the moisture in the air to obtain dry air. When the moisture absorption runner area rotates to the box regeneration area, The water absorbed by the air desorbing and dehumidifying runner heated by the regeneration heater is discharged to the outside, and the moisture absorption and desorption of the runner are carried out at the same time to ensure that the dehumidifying unit can provide stable dry air
The drying air outlet of the dehumidifier is an aluminum alloy four-way air flow regulating air outlet, so that the drying wind energy can be evenly sent to each area of the drying room. The air return outlet is an aluminum alloy air outlet with upper and lower adjustment, which can ensure that the return air is the moist air in the lower layer of the drying room
Working principle and operation diagram of (ZEDO) cold storage rotary dehumidifier
To sum up, many pharmaceutical factories and thermostatic chambers (such as seed cultivation) need dehumidification in a special environment of low temperature and humidity. The ordinary dehumidifier is suitable for the environment of 5-38 ℃. When the ambient temperature is lower than 5 ℃ and the humidity is required to be lower than 30% RH, the ordinary dehumidifier is powerless. Therefore, the (ZEDO) low-temperature dehumidifier or rotary dehumidifier is required
