• Ventilation System

  The ventilation system of a clean room is the basis for maintaining a high level of cleanliness. This system usually consists of fans, filters and fresh air systems that work together to maintain the purity of the air inside the shed. Fans are responsible for bringing filtered air into the clean room, while filters, such as HEPA (High Efficiency Particulate Air) and ULPA (Ultra High Efficiency Particulate Air) filters, are used to intercept particles in the air. The fresh air system exhausts the old air from the shed and replenishes it with new filtered air to maintain pressure and cleanliness in the shed.

• Positive Pressure Control

  Positive pressure control is one of the key features of a clean room, which means that the pressure of the air inside the clean room is higher than that of the outside environment. This setting effectively prevents contaminants from the outside from entering the cleanroom.

• Filtration

  Filtration technology is a critical part of a clean room and ensures that airborne particles are effectively intercepted and filtered through a multi-stage filter system, such as primary, secondary and high efficiency filters.

Installation Steps

Pre-Preparation

• Environment preparation: Ensure that the installation area is dry, ventilated and well lit, avoiding direct sunlight.

Material and tool preparation: prepare the required materials such as stainless steel plate, clean plate, etc., as well as tools such as screwdrivers, leveling tape and so on.

• Preparation of construction personnel: Construction personnel need to wear protective equipment such as dust-free clothing, hats, masks and shoe covers to minimize contamination.

Foundation construction

• Ground treatment: Ensure that the ground is level and firm, and if necessary, clean and disinfect the ground.

• Wall construction: build walls, paste bricks and carry out waterproof treatment according to the design requirements.

Frame Installation

• Section steel frame: use section steel to make the frame, ensure verticality and horizontality, and carry out anti-corrosion and anti-rust treatment.

• Roof and wall plate installation: use purification board or other materials that meet the clean requirements to ensure the flatness of the roof and wall plate and the tightness of the joints.

Filtration system installation

• High-efficiency filter: choose the right type of filter and install it according to the direction of airflow.

• Air shower room and ultraviolet disinfection lamp: install air shower room and ultraviolet disinfection lamp to ensure the effectiveness of air purification.

Lighting and Electrical Construction

• Lighting system: Installation of LED lamps and lanterns, etc. to ensure the waterproof and dustproof performance of lighting equipment and the uniformity of lighting.

• Electrical system: Installation in accordance with national standards and industry requirements to ensure stable and safe power supply.

Installation of other facilities

• Doors and windows installation: choose appropriate types of doors and windows, and use sealing materials to ensure sealing performance.

• Ventilation equipment: install exhaust fans, air conditioners, etc. to regulate the temperature and humidity in the clean shed.

Cleaning and Acceptance

Upon completion of the installation, cleaning and acceptance work is carried out to ensure that the clean room meets the cleanliness requirements.

Precautions

• Design requirements: Ensure that the design and specifications of the clean room meet the required cleanliness requirements and application scenarios.

• Installation location: Choose an appropriate location for the installation of the clean room to avoid the presence of large amounts of dust, mold or other sources of contamination.

• Cleaning and sanitizing: Ensure that the cleanroom itself is clean and sanitized prior to installation.

• Power and electrical safety: Connect to the power supply correctly and ensure electrical safety.

• Filter Replacement: Replace the filters in the Clean Shed on a regular basis, determining replacement intervals based on the environment in which they are used and the type of filter.

• Temperature Measurement Standards

  Temperature testing of the clean room should be carried out with high precision thermometers, and attention should be paid to the placement of the thermometers during testing to avoid the influence of external factors. In order to ensure the accuracy, it should be measured several times to take the average value.

• Humidity measurement standard

  For humidity measurement, it is also necessary to use a high-precision hygrometer, and pay attention to the placement of the hygrometer to prevent external interference. As with temperature measurements, take the average of multiple measurements to improve accuracy.

• Noise Measurement Standards

  Noise measurement should be carried out by using an accurate sound level meter, taking into full consideration of the environmental noise when testing, and improving the reliability of the data by taking the average value of multiple measurements.

• Wind speed measurement standard

  Wind speed measurement must rely on accurate anemometers, and in the measurement, attention should be paid to choosing the appropriate measurement position to avoid the influence of local airflow. Averaging multiple measurements is also a key step in improving accuracy.

• Air Quality Measurement Standards

  Air quality testing involves floating dust particles, ground settlement bacteria, falling bacteria and other aspects, you need to use the appropriate testing instruments, such as dust particle counters, etc., and in the appropriate location for multiple measurements in order to obtain an accurate average value.

• Illuminance measurement standard

  Illuminance measurement should use professional illuminance meter, and pay attention to the location of the illuminance meter, so as to avoid interference from external light sources. Taking the average value of multiple measurements is also to ensure the accuracy of the data.

• Testing equipment

  Clean room testing, commonly used instruments and equipment, including but not limited to the U.S. Lighthouse particle counter, the U.S. Emtek bacterial sampler, the Netherlands KIMO differential pressure meter, anemometer, air volume hood, noise meter, illuminance meter, temperature and humidity meter and so on.

• Measurement standard parameters of clean room

  Measuring standard parameters of clean room cover wind speed, air volume, air change times, cleanliness, etc. Specific technical parameters and standards based on the "Clean Room Design Standards" GB50073-2001, "Hospital Outpatient Clean Room Engineering Construction Technical Standards" GB 50333-2002, "Microbiological Safety Laboratory Engineering Construction Technical Standards" GB 50346-2004, "Clean Room Engineering Construction Standards" GB 50346-2004, "Clean Room Engineering Construction Technical Standards" GB 50346-2004, "Clean Room Engineering Construction Standards" GB 50346-2004 GB 50346-2004, GB 50591-2010 and other standards for the construction and acceptance of clean room projects.
