Design and construction of ultra-clean room decoration
1. Overview. Ultra-clean room refers to an indoor environment that has been specially designed and decorated with the characteristics of high cleanliness, dust-free, sterile and low noise. Ultra-clean rooms are widely used in electronics, medicine, food, biological products and other fields, as well as some industries with high environmental requirements. The design and construction of ultra-clean room decoration involves many aspects, including air purification, electrical, water supply and drainage, HVAC, fire protection and other professional fields. The following will introduce in detail the key points and precautions for the design and construction of ultra-clean room decoration.
2. Air purification system.
The air purification system is one of the most important components of the clean room, and its main purpose is to bring fresh outdoor air into the room, filter it through a high-efficiency filter, and then send clean air into the room through the air supply system, so as to maintain the cleanliness of the indoor air. In the air purification system, the following points need to be noted:
1.Filter selection: According to the requirements of the clean room and the type of indoor air pollutants, select the appropriate filter, including primary, intermediate and high-efficiency filters. At the same time, the service life of the filter and the maintenance replacement cycle need to be considered.
2.Air supply mode selection: According to the layout and space size of the clean room, select the appropriate air supply mode, including side air supply, top air supply, floor air supply, etc. At the same time, the number and location of the air supply outlets need to be considered to ensure that the air supply is evenly distributed.
3.Exhaust system design: The ultra-clean room needs to be equipped with an exhaust system to exhaust the indoor air outside. In the exhaust system, it is necessary to select the appropriate location of the exhaust fan and exhaust vent, and ensure the airtightness and low noise of the exhaust system.
4.Clean room layout: The layout of the clean room should be reasonable to avoid cross-contamination of ** and logistics. At the same time, auxiliary areas such as buffer rooms and cleaning rooms need to be set up to ensure the cleaning and disinfection of personnel and goods.
3. Electrical system.
The electrical system is another important part of the clean room, and its main contents include power distribution cabinets, cables, wires, sockets, switches, etc. In the electrical system, the following points need to be noted:
1.Distribution cabinet selection: According to the use requirements and power load of the clean room, select the appropriate distribution cabinet model and specification. At the same time, the location and protection level of the distribution cabinet need to be considered.
2.Cable and wire selection: According to the electrical load and current size, select the appropriate cable and wire model and specification. At the same time, the thickness of the insulation layer and the flame retardant properties of the cables and wires need to be considered.
3.Socket and switch selection: according to the use requirements and the number of personnel, select the appropriate socket and switch model and specification. At the same time, the location and number distribution of sockets and switches need to be considered.
4.Lightning protection and grounding system design: The clean room needs to be equipped with lightning protection and grounding systems to protect the safety of equipment and personnel. In the lightning protection and grounding system, it is necessary to select the appropriate lightning protection equipment model and specification, and ensure that the grounding resistance value meets the requirements.
Fourth, water supply and drainage system.
The water supply and drainage system is another important part of the clean room, and its main contents include water supply pipes, sinks, drainage pipes, etc. In the water supply and drainage system, the following points need to be noted:
1.Water supply pipeline selection: According to the water consumption and pressure requirements, select the appropriate water supply pipe model and specification. At the same time, the pressure resistance and sealing performance of the water supply pipeline need to be considered.
2.Sink selection: According to the use requirements and water quality, choose the appropriate sink model and specification. At the same time, the corrosion resistance and easy cleaning performance of the sink need to be considered.
3.Drainage pipe selection: According to the drainage volume and discharge standard, select the appropriate drainage pipe model and specification. At the same time, it is necessary to consider the pressure resistance and corrosion resistance of the drainage pipe.
