Bag air duct ventilation system and air conditioning ventilation system

With the expansion of the fiber fabric air distribution system market and the application problems of some special air conditioners, this paper expounds the cooperation between the fiber fabric air distribution system and the clean room air conditioning system.

Clean air conditioning refers to air conditioning systems in places where there is a need for cleanliness. The places with clean demand are clean rooms. The cleanliness levels are different according to the requirements. The design of the corresponding air conditioning system and the selection of equipment are very different. But in general, it can be divided into three categories: low clean demand, high clean demand and ultra high clean demand. Low clean demand refers to clean room below 10,000 cleanliness requirements. High clean demand refers to clean room with 10,000 to 1000 cleanliness requirements. Ultra high clean demand refers to cleanliness requirements above 1000. Clean room.

For clean space with low clean demand, it is only necessary to add a primary or intermediate filter at the air outlet of the air conditioning cabinet. In this case, the fabric duct system can fully meet the requirements of use. The clean air conditioning system of the air-conditioned room required by Gao Jiejing is to install an efficient or ultra-efficient filter at the end air outlet. Since the fiber fabric air distribution system cannot install the filter at the air outlet, the installation before the inlet will reduce the pressure and wind speed, which can not meet the minimum requirements of the fabric duct system. Therefore, we recommend using a drum filter in the clean room. Before the arrangement, the wind pressure and wind speed fully meet the requirements of the ventilation system of the fiber fabric air distribution system!

For example: a project, in the liquid milk filling area 2, because it is a purely refrigeration purification air conditioning area, the project requires low-speed air supply (wind speed less than 0.3m / s), can be cleaned, and required to achieve 300,000 level purification requirements. The traditional Yili milk factory uses a terminal high-efficiency filter. This project is used in conjunction with the fabric air distribution system ventilation system. A drum filter is installed in the rear filter of the AHU, and the fabric air distribution system is successfully used.

A New Star In Goji Berry – Black Goji Berry,

Black Wolfberry is popular in China. If you can introduce it to other countries, I think this is a new business opportunity.

Black goji berry grows in Qinghai-Tibet plateau China,where 3000 meters above the sea level,strong solar radiation, sunshine time up to 3600 hourshas, goodresistance tocold and dryconditions. The black goji berry grows in Gobi where people can not survive, it`s pure natural growth.

Black goji berry is rich in protein, LBP, amino acids, vitamins, minerals, trace elements and other nutrients. Also rich in natural proanthocyanidins, its OPC content more than blueberries (black fruit goji berry containing OPC 3690mg/100g; blueberries containing OPC 330 ~ 3380mg/100g). It is so far found the highest content of OPC in natural wild plants.

If you haven't eaten these small black berries, why don't you contact me, we give you a free small sample, and maybe you would like them.
