The pressurizer is a wind delivery device that is not very common or common in our lives, and that may not be known to many people, but is closely related to our lives. There are many malls, offices, hospitals, etc., where pressurizers are installed to prevent occasional need in case of fire. The pressurizers increase the rescue time for firefighters and play an important role in critical life-saving moments. The following is a summary of the price, operation and application of the pressurizer。
Description of the price of the pressurizer
Wind-repression opportunities vary according to the size of the gas-replacement area, and work and materials vary from plant to plant and therefore cannot be generalized。
The working principles of the pressurizer
The pressurizer is also called the positive pressurizer, most of which is a transducer-modifiable wind machine, which works by relying on the boost generated by the rotation of the wheel, and by moving the air along the axis from the inhaled side to the windway. It's pressuring the wind so that indoor smoke doesn't reach the stairs, creating conditions for people to escape. The pressurizer
When there is a fire, the power opportunities inside the pressurizer open the wind, the temperature smoke or a manual fire alert is opened, the tower roof is automatically open, the wind wells are pumped up, and the front room of the stairs is constantly ventilated to the front room, keeping the front room under pressure to ensure that the smoke does not spread in the area but gives space to escape. When the temperature is above 280°c, there is no chance of escape, the internal melting machine will melt and the wind vent will be automatically closed to prevent the fire from spreading。
Scope of application for pressurizers
1. Smoke-proof stairs, fire-fighting elevators, front or shared front rooms that do not have the natural means of smoking. 2. A smoke-proof stairs with a natural smoke-free front room. 3. Closed shelters. In all three cases, mechanical pressurization systems were not installed。
The pressurizers are normally installed on top of buildings and are associated with the pressurized wind valves on various layers. The air is usually drained out of bathrooms, bathrooms and kitchens, while fresh air comes in from the living room, bedroom, etc. At the beginning of the fire, the wind valves were opened, the pressurizers were activated, the stairwells and elevator halls were put in a state of normal pressure, which resulted in the release of polluted air from bathrooms, bathrooms and kitchens, while fresh air was brought in from the living room, bedrooms, etc。
The factors to be taken into account in the procurement of the pressurizers are the length of time spent, the amount of noise generated, whether the amount of wind blowing is sufficient and the ease of installation. Following recent technological updates, the use of new pressurizers produced by many manufacturers is now broader. In the event of a fire, the pressurizer provides fresh air for the safe passage, discharges smoke, and is more conducive to the escape of trapped persons and the rescue of firefighters。
