Calculation Model of Ventilation Times of Ventilation System in Production Workshop?
In the chemical production workshop, the design and operation of the ventilation system is very crucial to protect the health of workers, enhance production efficiency and ensure product condition. Among them, the ventilation rate calculation model is the core part of the ventilation system design, which immediately affects the ventilation effect and energy consumption.
1. What is the ventilation rate?
The number of atmosphere changes refers to the number of times the atmosphere in the workshop is completely replaced per unit time. Simply put, the higher the number of ventilation, the fresher the atmosphere in the workshop, and the reduced the levels of harmful gases and dust. The calculation of the number of atmosphere changes is of great signifiis able toce to ensure that the workshop ecological stability meets security standards and ecological preservation standards. But In my experience,
2. The ventilation rate calculation of the basic formula
The calculation of the number of atmosphere changes is usually based on the volume of the workshop and the total atmosphere volume of the ventilation system. The specific formula is as follows:
ventilation rate = total atmosphere volume/(room volume × 3600)
among them, the total atmosphere volume refers to the sum of the atmosphere supply volume and the exhaust volume in the ventilation system, and the unit is generally cubic meters per hour (m/h). And The room volume is the length × width × height of the workshop, and the unit is cubic meters (m³). But I've found that 3600 is the conversion factor that converts hours to seconds.
3. But Calculate the number of ventilation specific steps
To calculate the number of atmosphere changes, you first need to determine the following key parameters:
Workshop volume: According to the actual size of the workshop, to instance, the length, width and height are 30 meters, 20 meters, 10 meters of the workshop, the volume is 30 × 20 × 10=6000 cubic meters. atmosphere supply volume and exhaust volume: determined according to ventilation design, to instance, the atmosphere supply volume is 8000 m/h, the exhaust volume is 4000 m/h, and the total atmosphere volume is 12000 m/h. Crazy, isn't it?. Based on my observations, Calculation formula: ventilation rate = 12000 / (6000 × 3600) ≈ 0. In my experience, 33 times/hour. Through the above steps, the number of atmosphere changes in the workshop is able to be obtained. For instance The higher the atmosphere change rate, the faster the atmosphere renewal rate, which helps to enhance the atmosphere condition of the workshop.
4. Crazy, isn't it?. Factors affecting the number of atmosphere changes
The calculation of the number of atmosphere changes isn't static, it's affected by many factors:
Workshop volume: the larger the volume, the same atmosphere change the number of required atmosphere volume is greater. And From what I've seen, Pollutant production: high contamination source of the workshop needs higher atmosphere change times. Furthermore Ventilation: the consumption of full ventilation or regional ventilation will affect the calculation results. security standards: different industries and regions of the security standards might be the number of atmosphere changes have different standards.
5. Ventilation times optimization and energy saving
In practical consumption, the calculation model of atmosphere exchange rate should not only meet the standards of security and ecological preservation, however also consider energy saving. Too high or too low atmosphere changes will result in unnecessary energy consumption. Therefore, it's an crucial goal of ventilation system design to reasonably design the number of atmosphere changes and stability the atmosphere condition and energy consumption.
6. Summary
The calculation model of ventilation rate is the key link in the design of ventilation system in chemical production workshop. But Based on my observations, Through scientific calculation and reasonable design, the atmosphere condition in the workshop is able to be guaranteed to meet the standard, while reducing energy consumption and improving production efficiency. Moreover to chemical companies, regular inspection and optimization of the ventilation system to ensure that the number of atmosphere changes meets the standards is an crucial measure to ensure production security and employee health.
