For the renovation of the small and medium-sized dust-free workshop in the workshop decoration, the old workshop is also the small and medium-sized dust-free workshop, so the dust-free workshop cannot be built according to the requirements of the new decoration. But according to the actual situation, combined with the basic principles of air purification, we should design a set of useful transformation scheme, which includes air circulation form and structure form.
1. Air circulation form
The operation mode of this set is that the air enters the static pressure box through the air supply equipment, enters the dust-free workshop after filtration, and then enters the return air passage from the fresh air equipment. Among them, a part of the return air mixes with the air in the fresh air equipment and enters the fan room. The other part of the return air directly enters the air inlet of the air conditioner. After the air is cooled, it enters the fan room through the guide hood and the cooling air pipe. After the two parts of air are mixed in the fan room, the mixed air is sent to the static pressure box through the medium efficiency filter, and then to the dust-free workshop through the high efficiency filter, which forms a cycle.
From the air circulation situation described above, we can know that this air circulation form constitutes a good three-stage filtration condition, and then ensures the overall air quality of the dust-free workshop. On this basis, the structure and layout of the air supply outlet of the high-efficiency filter can be adjusted, together with the corresponding air volume, to adjust the clean form and cleanliness of the dust-free workshop, so as to get used to different needs.
2. Structural form
The general structure of the small and medium-sized dust-free workshop in the workshop is that the wall is made of sandwich color steel plate, and the top is equipped with a fan room, which is equipped with a fan case. All around the fan room are closed, and a medium efficiency filter air inlet for inward ventilation is provided. The fan is installed in the fan case, under which are the static pressure box and high efficiency filter. There is no primary return air filter at the lower side of the dust-free workshop, and there is a return air duct at the outer side. There is a split air conditioner between the return air ducts.
The air outlet of the split air conditioner is provided with a guide cover and a cooling air pipe. One end of the cooling air pipe is installed in the air outlet and the other end is installed in the fan room. As for the model of split air conditioner, the general type can meet the needs of small and medium-sized dust-free workshops. If the air supply distance is remote, fans can be installed on the cooling air duct to add air supply pressure.
