Necessity of dehumidification in cold storage

Food cold storage can get rid of the impact of climate on food, fruits and vegetables, extend the storage time to a greater extent, better preservation and quality.

    Food safety has always been a hot topic. Safe storage is closely related to food safety! However, there is still a big gap between the per capita share of cold storage in China and developed countries, and the storage quality of cold storage is also different. High humidity is a common problem in cold storage, which is caused by excessive air humidity. The humid environment is not conducive to the preservation of food, fruits and vegetables in cold storage, so dehumidification in cold storage can not be ignored.

  Cold storage dehumidifier with low temperature dehumidification function, a good solution to this problem.

  Today, I'd like to introduce some knowledge of dehumidifier for low temperature and cold storage for your reference, which is convenient for consumers to use and buy dehumidifier for cold storage.

Operation principle of low temperature dehumidifier:

      The moist air is drawn into the evaporator by the fan, and the evaporator surface is lowered below the dew point temperature of the air through the compressor refrigeration system. The water in the air is adsorbed on the evaporator surface, and the water will flow along the hydrophilic aluminum foil on the evaporator to the water tank, and then to the water tank or drain pipe for discharge, The dehumidified dry cold air is heated by the heat recovered from the condenser, and then the dry air is discharged from the machine, so that the wet room can achieve the effect of drying. During long-term operation, the evaporator surface will freeze due to low temperature. The system will automatically determine the coil temperature and start heating and defrosting. So as to achieve the purpose of continuous dehumidification of compressor. After defrosting, the system will automatically switch to dehumidification mode.

  Applicable place and environment of low temperature dehumidifier:

  The low-temperature dehumidifier is used in the relevant places of low-temperature refrigeration. The ambient temperature is 2-10 ℃ and the humidity is 50% - 70%. The condenser and evaporator are exchanged according to the fin temperature of the equipment under low temperature to ensure that the compressor does not stop at low temperature.

  9. Humanized design:

  1. The structure of the whole machine is reasonable. It adopts "intelligent fan delay shutdown" system and full automatic microcomputer control. The machine is equipped with humidity and temperature display. The humidity can be set from 30% to 90%. When the humidity reaches the set value, it will stop automatically. When the humidity is higher than the set value, it will start automatically to dehumidify (after the humidity is set, the machine will automatically sense the air, start automatically when the humidity is wet, shut down automatically when the air is dry, full automatic control).

  2. 1-24 hours with self-test function. When you go out, you can rest assured. The timing switch function, 1-24 hours setting, makes it convenient for you to turn off the machine when you go out. There is no need to watch, automatic induction, self dehumidification. The machine is equipped with automatic fault detection function. If there is a fault, the machine will automatically detect the cause and display the corresponding fault code to facilitate maintenance.

  3. The inner thread copper tube has a large amount of heat dissipation. Sufficient materials, good heat dissipation effect of copper tube, long service life.

  4. All copper tube and two vessels. Wet Teng two are made of copper tube, other brands use composite tube, low cost.

  5. Humanized design, easy to operate. Hose connection, automatic drainage. Independent 360 ° Universal wheel. Super quiet eight wheel bearing universal wheel.

  6. Power off memory function. Power off memory function, a set, the machine automatically switch on and off throughout the year, once the power failure, such as power, it will automatically start, do not need to start manually.

  7. Dajin brand compressor has a service life of 8-10 years. We use Dajin brand compressor, first-line brand, brand guarantee, three-year replacement—— Service life up to 8-10 years, professional dehumidifier manufacturers, use more assured.

  8. 300-400 Ping, 240 L / d. Industrial choice, real data, not virtual standard. Calculation formula of dehumidification area of some shops: Power × Dehumidification capacity × Air volume factor ÷ 100 = area, the calculated area will be much larger than the actual dehumidification area, resulting in poor dehumidification effect.

  9. Stainless steel body plate, no rust, durable.

  matters needing attention:

    Keep the sensor clean: for dehumidifier with humidity sensor, the humidity sensor is generally placed on the ventilation surface. If the environment is not good and the humidity sensor is blocked by dust, the sensor cannot display and control the humidity. Please use a soft brush to clean the dust on the sensor and keep the sensor fresh.

    Keep the filter clean: after the dehumidifier is used for a period of time, its air inlet filter will accumulate dust, and the dust accumulation is too dense and thick, which will affect the dehumidification effect. Therefore, it is necessary to clean the filter screen frequently. Make the front and rear ventilation smooth.

      Prevent compressor damage: refrigeration dehumidifier is the principle of compressor refrigeration dehumidifier, because the compressor is a high-tech component, but also the heart of the whole dehumidifier, so the compressor has certain requirements for the quality of the power grid, the compressor is often used in an unstable voltage environment, which will lead to compressor coil short circuit and other faults.
