In order to realize the overall ventilation of Jinan ventilation pipeline, mechanical ventilation and natural ventilation can be used. According to different action mechanisms, total ventilation can be divided into dilution ventilation and displacement ventilation; according to different characteristics of the system, comprehensive ventilation can be divided into three categories: comprehensive air supply, comprehensive exhaust and comprehensive supply and exhaust. Do you know what mechanical ventilation methods are? Next, Jinan ventilation pipe processing factory will be briefly introduced in the following, hoping to help you.
1. Displacement ventilation
In the displacement ventilation system, fresh cold air is discharged from the bottom of the room at a low speed of Ji, and the temperature difference of the air supply is only 2-4y. The fresh air in the room diffuses at the bottom of the room like water due to its high density.
The heat convection caused by the heat source makes the room produce a vertical temperature Zen degree. The air flow rises slowly, leaving the work area, pushing the waste heat and pollutants to the top of the room, and then directly discharging through the air outlet on the ceiling or the top of the room.
Indoor air flows like a piston, pollutants are discharged from the top of the room with the airflow, and the working area is basically empty. In other words, the concentration of pollutants in the work area is roughly the same as that in the air. Jinan ventilation pipe manufacturers said that displacement ventilation and traditional dilution ventilation have a big difference. The ventilation effect of displacement ventilation was better than that of dilution ventilation.
2. Local ventilation
Local ventilation is the use of local air flow, so that local areas are not polluted by harmful substances and produce a good air environment. Local ventilation system is divided into local air supply and local exhaust. Local emission is to collect and purify pollutants on the spot and then put them outdoors.
Local air supply is to send qualified air to the local workplace to ensure the local air conditions. As a technical measure to ensure the air quality of working and living environment and prevent indoor environmental pollution, local ventilation should be given priority.

3. Dilution ventilation
Dilution ventilation, also known as mixed ventilation, refers to sending people to mix the air below the indoor pollutant concentration with the indoor air, so as to reduce the indoor pollutant concentration which is difficult to reach the hygienic standard.
This is the end of the three mechanical ventilation methods of Jinan ventilation duct. I believe that you have a deeper understanding after reading these contents. I hope these contents can help you.
