In general, the cooling load of the clean room is also increased in view of the large energy consumption per unit air volume of the single air shower system. The estimation under specific circumstances (1) FFU is suitable for the old buildings to be converted into clean rooms, and its summary economy is generally desirable. When the final filter is full, it is still uneconomical to select FFU for large system in clean room with strict cleanliness requirements, and to compare the significance of small system. (3) For clean rooms with less stringent cleanliness requirements, when the final filter filling rate is less than or equal to 40%, there is no significant difference in economic efficiency. However, for IC plants, the sensitivity of FFU system is the key. The wind shower room reports that FFU system has been widely used in IC factories when the filter full coverage rate is less than or equal to 40%.
The air supply surface must be larger than the working area, each side should be 3-35cm larger, and the size should not be less than 20cm. This is due to the fact that the inlet air flow has a limit layer. (2) Assuming that part of the 100 class area is very small, in order to ensure a satisfactory wind speed on the working face, the outlet speed of the air supply should be increased. (3) In order to ensure the cross-section wind speed and cleanliness of the working area, the single air shower chamber can be equipped with rigid or flexible resistance wall or curtain of appropriate length under the laminar flow hood or part of the 100 grade air supply surface, but it is not vertical to the ground as mentioned above. The intention is to make the downward unidirectional flow continue to the working face. The result of this is to widen the air supply outlet or reduce the interval between the air supply outlet and the working area.
Next, let's learn about the quotation of single hair dryer! A typhoon shower room is composed of one or more air shower units. For large volume air shower equipment, it can be divided into several modules, which makes the production, transportation and equipment extremely convenient, and the single air shower room is fast; high function and high sealing: the imported electronic equipment is selected, the operation function is stable and reliable, the advanced noise reduction and mute equipment system and the selection of EVA sealing data have high sealing function. Cargo shower, also known as cargo shower channel, is a kind of air shower. It is a kind of purification equipment for goods between clean area and non clean area of air shower room. However, associated with other purification equipment, single air dryer has its own characteristics.
Equipment: 1. The equipment should be installed in all levels of purification plant or sealed air conditioning plant. 2。 The equipment address should be away from high-speed dust source and source. 3。 After the equipment, it is necessary to clean the inside and surrounding environment of the equipment with ultra clean vacuum cleaner or things without fiber seizure. After cleaning the equipment in the single blow shower room, qdf-2 hot bulb anemometer can be used to measure the uniform wind speed in the purification work area. When the uniform wind speed is less than 0. When the wind speed is 32m / s, adjust the voltage of the voltage regulator and increase the input voltage of the fan; otherwise, when the uniform wind speed is greater than 0. At 48m / s, reduce the voltage of voltage regulator and the input voltage of fan until the uniform wind speed is kept at 0. It can only be used within the scale of 4m / s ± 20%.
At this point, the article about the quotation of single single hair dryer has been finished. Thank you for your reading.
