The laboratory process design should reflect the characteristics of standardization, intelligence, humanization and flexibility, while considering the scope of service, customer needs, regional economy, industrial development, etc., and consider the forward-looking nature of future development. Process design determines the advanced nature of the laboratory and is an important part of modern laboratory construction. The civil engineering design is designed according to the process planning and process requirements. Therefore, the process design should precede the civil engineering design. Whether the process design of the laboratory is scientific and reasonable has a significant impact on the laboratory's work efficiency, inspection quality, environmental quality and cross-contamination. On the basis of reference to the design concepts of advanced laboratories at home and abroad, according to the construction experience of the National Quality Inspection Center, the principles of modern laboratory process design are summarized as follows:
1. Scientific and reasonable principles
The laboratory shall hold the design in accordance with the principle of “scientific planning and rational layout” to achieve advanced technology, safety, reliability, economic rationality and quality assurance. The location of the laboratory should be reasonable, the layout should be scientific, and all kinds of houses should be arranged in a centralized manner, so that the functional division is clear, the layout is reasonable, the connection is convenient, and there is no interference. The laboratory design should also fully consider the rational design and configuration of the experimental work space, ventilation system, gas supply system, fire protection system, water supply, strong and weak electricity, equipment and equipment grounding, labor protection and the corresponding air-conditioning HVAC infrastructure.
2. Efficiency and efficiency principle
The functional area and equipment layout are designed to meet the inspection workflow, optimize the laboratory's workflow, shorten the round-trip distance of personnel, and improve operational efficiency. Energy-saving equipment is used to optimize pipeline layout to save construction costs and reduce operating costs. In addition to optimizing the layout of the layout, advanced laboratory management software can be used to optimize the experimental process and improve work efficiency.
3. Safe low carbon principle
The green laboratory is the mainstream of the 21st century laboratory. Safety, health, environmental protection and energy conservation are the elements of the green laboratory. The laboratory design should be simple, transparent and generous, follow the principle of “less modification and less modification”, and consider the application of energy-efficient new technologies such as HVAC energy conservation, solar wind energy utilization, external wall insulation, lighting energy conservation, etc. Safety protection system and waste water treatment system reduce toxic and harmful substances, improve indoor and outdoor environment, and protect personnel health.
4. The principle of human intelligence
Humanized design is to use the laboratory's architectural space to provide a place for staff to communicate, including conference rooms, atrium space, stair space, tea lounge, public service space, etc.; pursue space visual beauty, neat appearance and color, safety Comfortable indoor environment to meet the communication and comfort needs of the staff. Intelligentization is to connect the various instruments and equipments of the laboratory to realize the network of the laboratory, so that the staff can grasp the various information of the laboratory through the information management system; the intelligence should be based on the actual situation of the scale and functional requirements of the laboratory. Meet the requirements of advanced, reliable, standard, integrated, practical, economical, and simple.
5. Forward-looking flexibility
For laboratories with large changes in market demand, a modular layout with adjustable structure can be considered in design, and there is enough space for equipment and equipment, and the supply system (including circuit, waterway, gas path, communication, etc.) can meet future development. It is required to be able to connect or disconnect easily on walls and ceilings. If necessary, the laboratory's workbench can be moved, the service column can be adjusted for movement, and the movable partition wall can be designed for flexible partitioning.
