What needs to be considered in laboratory planning and design?

Laboratory design planning is different from ordinary architectural design planning. Laboratory planning should not only consider the purchase of reasonable laboratory equipment, but also consider the overall planning of the laboratory, the reasonable layout of the laboratory, the laboratory process, the laboratory power supply, the infrastructure and water supply, drainage, and the basic conditions of the laboratory. Communication, network, heating, laboratory ventilation, laboratory air purification, safety and fire prevention, environmental protection, etc.

Therefore, laboratory construction is a very complex system engineering. Advanced science and a superior experimental environment are necessary to modernize the laboratory. Intelligence, safety, efficiency, comfort, energy saving, and environmental protection are the ideal elements of laboratory construction.

1. Scalability:

Lab systems are based on additive, modular forms and reusable operating systems that can be scaled up and down without sacrificing certain features or impacting the lab in question.

2.Patency:

Laboratory walkways and entrances and exits will allow easy access to the movement and provide relevant in-country regulations.

3. Flexibility:

There is plenty of space for instruments and equipment in each lab. Each board can also be used independently, so that the module configuration can not be changed without affecting the laboratory involved.

4. Security:

The area configuration in the laboratory needs to be divided according to its potential hazard level. In the higher danger zone, i.e. behind the laboratory (away from the exit), there will be smoke barriers, storage sites for acidic and flammable materials, and space allocated for biosafety batteries. A second layer of protection will be created with a defined space and sufficient waste access to protect the higher danger zone.

The low-hazard zone in each laboratory will be used to arrange various dry desk activities, such as setting up desks, computers and equipment. Wet table activities are placed in dangerous intermediate areas.

5. Economy:

The laboratory takes into account the efficiency of protection, work and configuration of zoning, thus avoiding the waste of area and space.

1) Schematic design.

According to the tasks and basic requirements of laboratory construction, the architectural scheme design is carried out on the basis of the preliminary preparatory work, and the plan is generally required to meet the laboratory function, with a sense of the times in appearance, in line with urban architectural planning, and the design is demonstrated, reviewed and compared by experts, and an implementation plan or the advantages of several schemes are proposed to further make a more satisfactory design scheme.

2) Preliminary design.

The specific implementation plan on the basis of the design scheme is the main basis for the construction drawing design, mainly including: design basis, design concept, general plan, scheme design of major construction projects, main material consumption, process design, three wastes treatment, life organization and labor quota, relevant technical and economic indicators, seismic civil air defense, construction sequence and deadline, etc.

3) Construction drawing design.

According to the preliminary approval documents, give the size of the relevant professional projects in detail, detailed practices, etc., to guide the installation of on-site construction drawings, arrange materials and equipment, and accordingly make a detailed budget for the final stage of the design work, its main contents include: general plan, construction, structure, water supply and drainage, electrical, heating and ventilation and related professional equipment system design, accurate and detailed description of their location net distance, coordinates, elevation, structural form, node details, material practices, size, material model, Equipment specifications or selected standard drawings, component details, quotation marks, technical requirements for construction and installation, and inspection methods for special parts, etc.

Including functional jujube room, ventilation system, HVAC system, gas supply system, water supply system, laboratory furniture, etc. Refine these main parts, and Zheng Qiao can dismantle them with Qi Cong.

The following aspects can be noted.

1. Construction.

The laboratory should be built with fire-resistant or non-flammable materials, and partitions and ceilings should be built with fire protection in mind. The windows should be dust-proof and the interior should be well lit. Doors should be opened outward, and large laboratories should have two exits to facilitate the evacuation of personnel in the event of an accident.

2. Water supply and drainage water supply should ensure the necessary water pressure, water quality and quantity to meet the needs of the normal operation of instruments and equipment. We believe that the main valve in the room should be located in a conspicuous position that is easy to operate. The sewer should be made of acid and alkali corrosion-resistant materials, and the ground should have floor drains.

3. Gas supply and power supply.

Conditional laboratories can be equipped with piped gas. The power supply of the laboratory is divided into electricity for lighting and electricity. Lighting is preferably fluorescent.

In the electricity consumption of the equipment, the electrical appliances such as refrigerators running for 24 hours are supplied separately, and the rest of the electrical equipment are controlled by the main switch, and the electric heating equipment such as ovens and high-temperature furnaces should have special sockets, switches and fuses. Install emergency lights indoors and corridors in case of sudden power outages at night.

4. Ventilation facilities.

Because toxic or flammable gases are often produced in laboratory work, the laboratory should have good ventilation conditions, and there are generally three kinds of ventilation facilities

Local exhaust hood: Generally installed above the part where harmful gases are generated in large instruments. Above the harmful gases generated in the teaching laboratory, a local exhaust hood is set up to reduce indoor air pollution.

Whole room ventilation: exhaust fan or ventilation shaft, the number of air changes is generally 5 times.

Fume hood: This is a type of local exhaust equipment commonly used in laboratory design. The fume hood can be made of fireproof and explosion-proof metal materials, coated with anti-corrosion coatings, and the ventilation ducts should be resistant to acid and alkali gas corrosion.

5. Laboratory furniture.

Laboratory furniture mainly includes laboratory benches, fume hoods, medicine cabinets, explosion-proof cabinets, gas cylinder cabinets, universal hoods, etc. It can be configured according to the functional requirements.
