Back to the wind in the pharmaceutical engineering design laboratory, preparation room purify price, by regular medicine Design Institute programs generally take into account the way back to the wind, to avoid dead ends, but in the construction often occur due to various factors some deviations, making the return air shaft or air location must be appropriately adjusted. The design of the program, often there will be some problems caused by irregular design units (such as cleanup and construction units), which will affect the cleanliness of the clean room. 1.1 and return air outlet on the same side, depending on air supply, air purification technology systems can be divided into laminar and turbulent systems. Filters and air handling systems turbulence relatively simple, easy expansion, low cost laboratory, preparation room purification Which is good, but the less the number of ventilators. So, usually turbulent system as ten thousand, one hundred thousand air form and three hundred thousand Clean area. Among them, the purification of air between the top side of the multi-way return air corridor ten thousand and 100,000 purification zone sometimes with top air and the wind blowing the way back to the top. Part due to factors such as story mode also uses the underside of the upper air wind back. For a variety of turbulent air in the form of laboratory systems, preparation room purification, require feeding in principle wind through the entire room. If the outlet and return air on the same side, often short-circuited air phenomenon will appear. Supply air, return air may appear on the same side in the following situations: (1) the top and back to the top of the wind blowing air supply; (2) at the same time on the same side of the wall outlet and return air arrangement; (3) return air outlet and the wall on the lower side of the roof to one side of the grave; 2 height appeared in (4) room at specialized laboratories, preparation rooms purification, low roof (or platform) following no air and no return wind. Four cases of air, return air layout will make the room air to form a short circuit within the phenomenon of cleanliness on the other side of it is difficult to guarantee, and will affect other areas. In particular, the fourth most frequently occurring situation, but easily overlooked.
