The ventilation warehouse is basically the same as the large warehouse, with three types: ground floor, semi-underground and underground. With long-term use of wood, masonry and other permanent construction, it does not require annual demolition and relocation. The ventilation warehouse has a good thermal insulation device, which differs from the warehouse pits in that it has sensitive ventilation equipment.
It is the use of more fresh and cold air outside the library, to discharge the hot and dirty air inside the warehouse to lower the temperature inside the warehouse. As a result, its cooling performance is better than that of the cellar. Due to the great influence of natural temperature on ventilation, it cannot be applied in summer. In the spring and autumn seasons, the indoor temperature is adjusted by using night ventilation. In winter, insulation is needed to prevent freezing, and heating equipment is sometimes needed.
Ventilation storage should be built in a well-ventilated, well-ventilated area that can quickly reduce the temperature inside the store. It is advisable to extend north and south in the north, which can reduce the direct attack of the cold north wind in winter and avoid freezing the vegetables when the temperature of the reservoir is too low. In the south, it is better to extend in the east-west direction. This will reduce the influence of the western sun and avoid excessive temperature fluctuations in the warehouse.
The plane of the ventilated storage is rectangular. There should be a cold-proof suite at the entrance and exit so that there is a buffer zone inside and outside the warehouse so that the inside of the warehouse will not be directly affected by the external temperature. Ventilation storage must be established into the intake and exhaust. The air outlets are generally located on the top of the library or above the side walls. The air inlet is located in the lower part of the side wall of the storage. Some ventilated storages are ventilated by the natural convection of hot and cold air. In good conditions, the electric exhaust fan is used to force air convection to achieve ventilation.
The main management of ventilated storage is to control temperature and humidity. In the early autumn, the amount of ventilation should be increased to quickly reduce the temperature inside the reservoir. As the temperature decreases, the ventilation opening is gradually reduced to reduce the ventilation. When the winter is cold, you should close the air intake and only open the air outlet. In late spring, night ventilation should be strengthened to prevent the temperature inside the warehouse from rising. The principle is the early cooling, medium-term insulation, and late temperature control.
As a result of ventilation and dehumidification in a ventilated storage room, the general humidity will not be too large. In order to increase the humidity inside the library, water can be sprinkled on the ground, and the sacks can also be placed at the air inlet to use the flowing air to bring in the evaporated moisture to increase the air humidity. If the humidity in the library is too high, in addition to the enhanced ventilation, moisture absorption materials such as lime can be used to reduce the humidity inside the library.
Frequently used ventilated storage warehouses are prone to pests and diseases in the warehouse. Therefore, at the end of storage, they should be promptly cleaned and fumigated with sulfur or sprayed with 0.5% bleaching liquid.

Water is vital to human life. Drinking water, swimming pool water, SPA water, aquarium water, fish pond water, is related to the quality of everyone's life, every day to contact, then how to ensure the quality of water? Water quality test strips, of course. These convenient and easy-to-use strips quickly and accurately test for a range of contaminants and keep you and your family safe.
TEST PROCEDURE
Immerse the strip for 2 seconds and then remove the strip.
Do not shake excess water off, and then hold the strip horizontally for 20 seconds.
Compare against the color chart and read immediately within 30 seconds to get accurate result.
IMPORTANT TO KNOW
1.Test for 30 seconds
When using the Water Test strip, your results are complete (ready to compare) after dipping the
test strip. Upon completion, make sure to compare your results immediately. The strip is no
longer valid outside of the 30 second testing period Discard the test strip after 60 seconds as
any further color change will be meaningless.
2.Prevent altered results
Here`s what you can do to prevent decreased shelf life of the strip and altered results
Do Store in a cool dry place away from direct sunlight.
Do read the instructions carefully before use.
Do Avoid touching or polluting test areas of the strip.
Do not place wet fingers in the bottle.
Do Keep the cap on tight between use.
Do not remove the desiccant pouch.
3.Primary and Secondary water Regulations
The EPA sets legal limits on over 90 contaminants in water test strip. There are two categories,
primary and secondary. Primary contaminants are substances that can be toxic in small amounts
On the other hand, secondary contaminants are less toxic species and would include cosmetic
issues (color, taste, and odor) of water. These strips test for the most commonly found primary
contaminants lead, fluoride, copper, chlorine, nitrite, nitrate) as well as the most commonly found
secondary contaminants(Copper, Iron, Sulfate, Zinc, Manganese, Fluoride, Chloride, and pH)
