As long as the ventilated environment can make the air refreshing, and this can not be separated from the ventilation project, the whole project will be based on the location of the affirmative plan, and ensure smooth ventilation, which central needs ventilation project?
1. Inside buildings: smoke exhaust equipment should be installed, but mechanical smoke exhaust should be used in rooms, aisles and atriums that do not have natural smoke exhaust conditions. High-rise buildings are mainly affected by natural conditions (such as outdoor wind speed, wind pressure, wind direction, etc.). Mechanical smoke exhaust is commonly used.
2. The following parts of civil air defense works:
1. The center where people often stay, or rooms or halls with more combustibles;
2. Demand ventilation engineering in consumer workshop;
3. Distributed walkways with comparatively long lengths;
In fact, these centers use ventilation engineering relatively more than the central, in addition, all the need for ventilation of the central, but also need it, its application is widespread.
Ventilation Pipeline Plant is a kind of municipal basic equipment for ventilation and air conditioning engineering of industrial and civil buildings, which uses metal or composite pipes to reduce the concentration of harmful gases. There are many kinds of ventilation pipes in Zhengzhou when they are manufactured. The small edition of the ventilation pipes below will share the advantages of the three-way connection and hope to be helpful to us.
The three-way joint is a three-way pipe joint, which is suitable for water, oil, steam, acid medium, etc. The three-way interface is mainly used for the connection of three pipelines to avoid leakage of water and air. Circular spiral duct and fittings, flat spiral duct and fittings are the advanced manufacturing technology of spiral duct abroad. They have the characteristics of small resistance, high strength, corrosion resistance, smooth inner surface, flat surface, convenient equipment, good sealing and strong applicability of circular spiral duct. They are in buildings, supermarkets, tunnels, factories, hotels and ceramics. The ventilation or the transmission of cold and warm air in kiln, dust collection and other operations are generally applicable. The spiral duct has the following advantages: good strength, small resistance, simple and convenient equipment, wide application and wide standard of spiral duct.
