Design Principles of Laboratory Ventilation Duct Engineering

實驗室建設過程中較不能忽視的工程之一就是通風系統了，今天咱們就來說說實驗室建設中通風管道工程的要求和相關參數是什么。

Ventilation system is one of the projects that can not be ignored in the process of laboratory construction. Today, let's talk about the requirements and relevant parameters of the ventilation pipe project in the laboratory construction.

實驗室通風管道工程的要求：通風效果好、噪音低、操作簡便、節約能源，室內壓差和溫濕度大多能保持人體的舒適性。

Requirements of the laboratory ventilation pipeline project: good ventilation effect, low noise, simple operation, energy saving, indoor pressure difference and temperature and humidity can keep human comfort.

實驗室通風工程的重要性：實驗室通風工程是整個實驗室設計和建設過程中，規模較大、影響較廣泛的系統之一。通風工程的完善與否，直接對實驗室環境、實驗人員的身體健康、實驗設備的運行維護等方面產生重要影響。

Importance of laboratory ventilation engineering: laboratory ventilation engineering is one of the systems with large scale and wide influence in the whole process of laboratory design and construction. Whether the ventilation project is perfect or not has a direct impact on the laboratory environment, the physical health of laboratory personnel, the operation and maintenance of experimental equipment, etc.

實驗室通風管道工程的設計原則

Design Principles of Laboratory Ventilation Duct Engineering

實驗室通風管道工程的設計原則：

Design principles of laboratory ventilation duct works:

1．處理設施具備沖擊負荷能力，確保廢氣達標排放。

1. The treatment facilities shall have impact load capacity to ensure that the exhaust gas is discharged up to standard.

2．夏天補冷風、冬天補暖風，保證室內溫濕度的舒適性。

2. Supplement cold air in summer and warm air in winter to ensure the comfort of indoor temperature and humidity.

3．采用智能變頻控制系統，達到操作方便、節能降噪的目的。

3. Intelligent frequency conversion control system is adopted to achieve the purpose of convenient operation, energy saving and noise reduction.

4．非標設備應符合國家或行業相關規范，并保證性能穩定、外表美觀。

4. Non standard equipment shall conform to relevant national or industrial specifications, and ensure stable performance and beautiful appearance.

5．綜合考慮各項因素，采用投資少、運行穩定、運行費用低、運行效果好的成熟工藝。

5. Comprehensively consider various factors and adopt mature processes with low investment, stable operation, low operation cost and good operation effect.

6．在設計中充分考慮噪聲、臭味等，防止二次污染的產生，不給周圍環境造成新的污染。

6. Noise and odor shall be fully considered in the design to prevent secondary pollution and new pollution to the surrounding environment.

7．所選擇的工藝建議滿足現場條件，平面布置簡潔、緊湊、少占地，并方便生產操作和維護維修。

7. The selected process must meet the site conditions, with simple and compact plane layout, less land occupation, and convenient production operation, maintenance and repair.

8．排風和補風系統達到風量平衡，保持室內-5Pa—-10Pa的負壓，防止有害氣體的散溢，保證實驗人員的身心健康。

8. The exhaust and make-up air systems shall achieve the balance of air volume, maintain the negative pressure of - 5Pa to - 10Pa indoors, prevent the diffusion of harmful gases, and ensure the physical and mental health of laboratory personnel.

9．根據大樓的結構特點，就近開設風井，劃分排風和補風系統，管道系統做到“短、平、順、直”，減小系統阻力，降低系統噪聲。

9. According to the structural characteristics of the building, set up an air shaft nearby, divide the exhaust and air supplement systems, and make the pipeline system "short, flat, smooth and straight" to reduce the system resistance and system noise.
