How to ventilate and cool the wet workshop, especially in the north? This is a headache. Generally speaking, the ventilation in the wet workshop is divided into two types, ventilation cooling and ventilation humidification. The specific requirements depend on the storage requirements of the products. Some are afraid of the tide and need a relatively dry environment. Some are afraid of drying and need a relatively humid environment. To introduce ventilation cooling and ventilation humidification.
(1) Ventilation and dehumidification Some products are afraid of moisture, such as hardware products, need to be ventilated to reduce the relative humidity inside the library. In the case of ventilation and dehumidification, the absolute humidity inside and outside the warehouse should be compared first, and then the relative humidity and temperature should be compared. Generally, only when the absolute humidity outside the warehouse is lower than that in the warehouse, ventilation and dehumidification can be achieved. However, the temperature and humidity changes inside and outside the warehouse are more complicated. Before ventilation, it must be carefully analyzed before it can be carried out. The timing of ventilation and dehumidification generally has the following conditions:
When the temperature and relative humidity of the air outside the warehouse are lower than the inside of the warehouse, it can be ventilated; the relative humidity inside and outside the warehouse is very close, and when the temperature outside the warehouse is lower than that in the warehouse, it can also be ventilated.
When the temperature of the air inside and outside the library is very close, and the relative humidity outside the library is lower than that in the library, it can be ventilated.
When the outside temperature and absolute humidity of the library are lower than the inside of the library, the relative humidity outside the library is slightly higher than that inside the library, and it can be ventilated.
In addition to the above, in other cases, it is generally not possible to cool down.
(2) Ventilation cooling, dehumidification When the temperature outside the warehouse, relative humidity and absolute humidity are lower than the inside of the warehouse, it can be ventilated to achieve the purpose of simultaneous cooling and dehumidification. For example, storing leather products requires simultaneous reduction of temperature and humidity.
(3) Ventilation and humidification Some commodities are afraid of dryness, such as bamboo and wood products, ventilation methods can be used to increase relative humidity. It can be ventilated when the relative humidity outside the library is higher than the relative humidity inside the library. When the outside temperature of the library is lower than the temperature inside the library and the relative humidity is equal to the inside of the library, it can also be ventilated, and the relative humidity in the library can be increased as the temperature is lowered.
After introducing the ventilation cooling and ventilation humidification, let us talk about the knowledge of automatic control and temperature and humidity adjustment.
Usually, the photoelectric automatic control device can automatically control and adjust the temperature and humidity of the warehouse, and automatically record. When the temperature and humidity in the warehouse exceed the specified range of the storage, it can automatically alarm, automatically open the warehouse window, automatically start the dehumidifier, automatically record, and automatically adjust the temperature and humidity in the warehouse. When the temperature and humidity in the library drop to the appropriate conditions, the dehumidifier can be automatically stopped and the ventilation window can be automatically closed.
Some workshops are relatively dry and can be found at http://specific consultation. Achieve everything to create a harmonious workshop cooling environment for you.
1X19 Stainless Steel Wire Rope
The steel wire rope plays the role of bearing the load, and its performance is mainly determined by the steel wire. The steel wire is a round (or special-shaped) wire made of stainless steel, carbon steel or alloy steel by cold drawing or cold rolling. It is used to increase the elasticity and toughness of the steel wire rope, lubricate the steel wire, reduce friction and improve the service life. Commonly used rope core organic fibers (such as hemp, cotton), synthetic fibers, asbestos core (high temperature conditions) or soft metals and other materials. Folding type 1. Round strand wire rope 2. Braided wire rope 3. Flat wire rope.
