Cold storage refers to the use of artificial means, to create a different environment from the outdoor temperature or humidity, but also for food, liquid, chemical, pharmaceutical, vaccine, scientific tests and other items of constant temperature and humidity storage equipment. Cold storage should pay attention to prevent the relative humidity is too high, then, cold storage humidity is too high how to dehumidify it?
Reasons for high humidity in cold storage:
1, moisture-proof insulation layer is not continuous, or thermal insulation construction has loopholes, resulting in the air outside the library into the cold storage, in the interior of the warehouse in the event of condensation dew, resulting in an increase in humidity in the warehouse, and even water, but also increased the thermal load of the warehouse.
2, the food into the warehouse with its own moisture. For example, before the food into the warehouse has been cleaned (just after the slaughter of fish, meat), or the moisture content of fruits and vegetables with high moisture.
3、Water brought in by fresh air exchange. When the cold storage is stored in the fresh goods, the need for regular air exchange, the library of carbon dioxide content of the air out, the introduction of new air. At this time may be water vapor with the external air into the cold storage.
Methods of dehumidification in cold storage:
To control the cold storage humidity, the first thing to check the cold storage moisture insulation function is intact, otherwise far from constant moisture supplementation, will make the cold storage heat load continues to rise, increase the chiller energy consumption and even affect the quality of goods. Secondly, you need to use a dehumidifier, general frozen dehumidifier in the cold storage will be frequent frost, can not be well applied, so you need to use the rotor dehumidifier.
Rotor dehumidifier is different from general industrial dehumidifier, it does not use the compressor refrigeration, so that the steam condenses into water for dehumidification, but through the new material polymerization of the rotor of the water vapor in the air adsorption, and then through the hot air will be adsorbed to bring the water to the outdoor.
General refrigerated dehumidifier, due to the compressor's working conditions, can only work in the ambient temperature of 5 ~ 35 ℃, even if the special low-temperature dehumidifier, can not be lower than -5 ℃, otherwise the machine will continue to frost, greatly affecting the efficiency of dehumidification; in the case of high temperatures is even more serious, sustained high-temperature work may even lead to compressor burned out.
As the rotor dehumidifier using adsorption dehumidification, do not need to be equipped with a compressor, the degree of adaptation to the temperature is much greater than the frozen dehumidifier, in the -20 ℃ ~ 60 ℃ of the environment are able to work smoothly, and continue to realize the effect of dehumidification, is widely used in cold storage and various types of high-temperature production workshop.
parkoo dehumidifier, focusing on the research and development of dehumidifiers, constantly explore various technologies to enhance the efficiency of dehumidification, and constantly upgrading the products, covering a wide range of fields, to provide customers with more satisfactory products.
