Clean Room Air Conditioning Duct Introduction

Clean room air conditioning duct has the following important uses:

A. keep the air clean

Highly efficient filtered air: The air that has been rigorously treated by the air conditioning unit is transported to various areas of the clean room through the air duct. The high efficiency filter installed in the air duct can effectively remove small particles, bacteria, viruses and other pollutants in the air, ensuring that the air entering the clean room reaches the required high cleanliness level. For example, in semiconductor manufacturing workshops, clean room air conditioning ducts can filter out particles 0.1 microns in diameter or smaller, preventing them from adversely affecting the chip manufacturing process.

Prevention of cross pollution: Through reasonable air pipe layout and air flow organization design, to ensure that the air flows in a specific direction, to avoid the air between different areas mixed with each other, so as to effectively prevent cross pollution. In the clean room of the pharmaceutical factory, the air flow in the areas of different production links needs to be strictly controlled to prevent drug pollution.

B. Control temperature and humidity

Precise temperature regulation: Heated or cooled air is delivered to the clean room to maintain a stable temperature environment. For some industries with high temperature requirements, such as electronic chip manufacturing, clean room air conditioning pipes can ensure that temperature fluctuations are controlled within a small range to ensure product quality. For example, during wafer manufacturing, temperature changes can cause wafer deformation and affect chip performance, so clean room air conditioning ducts require precise temperature control.

Stable humidity level: The air treated with humidification or dehumidification is fed through the air duct to the clean room to regulate the indoor humidity. In some clean rooms that require a specific humidity environment, such as biological laboratories, pharmaceutical workshops, etc., air conditioning pipes can ensure that the humidity is stable within the appropriate range to meet the requirements of experiments or production. For example, in the biopharmaceutical process, too high or too low humidity can affect the quality and stability of the drug.

C. Keep the air flow stable

Provide uniform air flow: Through a well-designed air duct system, the air flow in the clean room is evenly distributed, avoiding local air flow corners or turbulence. The uniform air flow helps to quickly take away the pollutants generated in the clean room and improve the efficiency of air purification. In a clean operating room, a steady and uniform airflow reduces the concentration of bacteria in the surgical area, reducing the risk of infection.

Maintain positive or negative pressure: According to the different needs of the clean room, by adjusting the air supply and exhaust air volume of the air duct system, the clean room can maintain positive or negative pressure. The positive pressure clean room can prevent the entry of external unpurified air, while the negative pressure clean room is used to prevent harmful gases or pollutants from leaking into the external environment. For example, in the isolation ward of an infectious disease hospital, the negative pressure clean room air conditioning duct can ensure that the air in the ward does not spread to other areas, protecting the safety of medical staff and other patients.

D. Energy saving and environmental protection

Optimize energy use: A properly designed air conditioning piping system can reduce energy loss during air transportation and improve the energy efficiency of the air conditioning system. For example, the use of air duct materials with good thermal insulation can reduce the energy loss of hot and cold air during transportation; Optimizing the layout and size of the air duct can reduce air resistance and reduce fan energy consumption.

Reduce the impact on the environment: Clean room air conditioning piping systems usually use environmentally friendly materials and technologies to reduce environmental pollution. For example, the use of recycled air duct materials and the use of low-noise fans both meet environmental requirements and provide a comfortable working environment for employees.
