In the clean engineering, the selection of ventilation ducts is very important. The cleanliness and air tightness of the pipeline itself are very high, because the wind pressure in the ventilation duct in the purified air conditioner is doubled compared with that of the ordinary air conditioner, so everyone can't pay attention to it.

The large-scale development of China's clean air-conditioning industry began in the mid-1970s. "The purification of air conditioners was a new topic for most people at that time. Everyone attached great importance to them. Of course, in engineering applications, ventilation The pipeline is also very important; the cleanliness and air tightness of the pipeline itself are very high, because the wind pressure in the ventilation duct in the purified air conditioner is doubled compared with the ordinary air conditioner, so everyone can't pay attention to it; indeed, the pipeline is clean. Degree and air tightness directly affect the operation of the entire purification system. It affects the wind pressure, air volume and even airflow organization, cleanliness, operating power and noise of the system.
At that time, due to the underdevelopment of the basic materials, the choice of materials was quite narrow. The use of steel-zinc steel plates for ventilation ducts was very advanced (at that time, most air conditioners used black steel plates to make pipes). Due to the high enthusiasm of the workers and the strong sense of responsibility, the craftsmanship is also very good. The airtightness of the pipes they make, such as the connection of the bite, is quite good, and the protective layer is also very regular. Small cold storage price
The testament is that the ventilation ducts for purifying air conditioners are still made today with steel-zinc steel plate bitings, angle steel flanges are connected, and the quality of the pipes is sometimes not guaranteed, as indicated in some investigation reports. : If the bite slit is not treated, the air leakage is more than 50%, and the most air leakage is 13%. This is a big waste in operation. However, in actual engineering, how many construction units are serious Handling this bite slit? Built cold storage price
