Laboratory construction process:

Laboratory workflow optimization is related to the overall and local layout, and is also closely related to hardware and software conditions. In addition to the optimization of the layout and the placement of the instrument and equipment, some advanced management software can be used to assist the staff to optimize the experimental process, so as to improve the work efficiency and reduce the influence of human factors on the experimental results.

In addition, a sound management system is also an important factor affecting the workflow.


The overall layout of the laboratory:

The layout principle is to meet the needs of workflow optimization and daily management. Design the main considerations of the process, the location of the special and functional, the specific environment of the upper and lower layers of the building, the building structure and other factors. Designers need to fully understand the user's specific needs and various experimental processes, whether to set up special functions, building structural features and other aspects of information and information. From the overall perspective of the building, consider the overall arrangement.

Interior layout:

The principle is to optimize the experimental work flow, reduce the intersection of people flow and logistics, environmental safety, health, color matching, harmonious and beautiful instrument and equipment placement, instrument supporting conditions (water, electricity, gas pipelines, ventilation, etc.).

Fire design:

  It is a special environment, and the requirements for fire protection are much higher than those of ordinary office buildings. Designers should use different fire protection measures to ensure fire safety based on the specific conditions (equipment investment and process characteristics, experimental process requirements, types of stored samples and reagents, and characteristics of buildings).

Power distribution design:

  The power distribution system is designed according to the specific requirements of experimental instruments and equipment, and has been designed by a wide range of factors by professional designers. It is very different from ordinary buildings. Because the requirements of the equipment for the circuit are more complicated, it is not what people usually think, as long as the requirements of large voltage and high power are met. In fact, there are many instruments and equipment that have special requirements for the circuit (such as electrostatic grounding, power failure protection, etc.). In the process of engineering construction, VOLAB found that most users did not fully consider the special requirements of power consumption in the initial stage of design and construction. Even some users and design units considered the power consumption similar to that of a general office. This brings a lot of trouble to the later operation. The design of the power distribution system should not only consider the existing equipment and equipment, but also consider the development plan for several years. Full consideration of the reservation of the power distribution system and future circuit maintenance issues.

 Water supply system selection: According to the requirements of water quality, water temperature, water pressure and water quantity in scientific research, production, life, fire fighting, etc., combined with factors such as outdoor water supply system, it is determined from the comparison of technical and economic indicators. The water quota, water pressure, water quality, water temperature and water use conditions shall be determined according to the process requirements. The water pipe is laid by the civil engineering side under the floor through the pre-embedded pipe and led to the designated position of the central station; for the side platform, the water pipe is buried in the wall by the civil engineering side and led to the designated position. The rest of the work is done by the construction unit.

Pure water system:

The water quality meets the requirements of the secondary water specified in GB/T 6682-1992 "Analytical Water Specifications and Test Methods". Pure water system, resistivity ≥ 5MΩ?cm. Ultra-pure water quality requirements: resistivity ≥ 18.2 MΩ? cm, 25 ° C. In addition, the pipeline transportation problem of pure water should also meet the relevant standard requirements.

Gas supply design:

Many of the equipment operates in a variety of gas supplies, as well as exhaust gases. How to solve the problem of supply and exhaust safely and conveniently is one of the problems that has always plagued staff. The traditional method of gas supply is to place the gas cylinder next to the equipment, and the gas cylinder of the dangerous gas is placed in the gas cylinder cabinet. The exhaust is discharged directly or through a simple pipe to the window. In the development process, with the increase of instruments and equipment, there are often a variety of pipes and cylinders. This treatment has caused a very large security risk and is not beautiful. The correct solution for the supply and exhaust is to treat the exhaust as a system. This system should take into account safety, convenience, daily management, gas cylinder replacement and other issues, while focusing on future development, special technical solutions for special gases.

Cylinder room design:

The gas is dangerous and complicated, and the gas should be specially considered for layout, classification, fire protection, power distribution, etc.

Air conditioning design:

  The general summer air conditioning indoor calculation parameters are: temperature 26 ~ 28 ° C, relative humidity less than 65%. Dedicated air conditioning indoor calculation parameters should be determined according to process requirements. The main function of the air conditioning system is to control the temperature and humidity. The air conditioning system works in conjunction with the laboratory ventilation system to effectively control the effective control of temperature and humidity and room pressure. In short, the requirements for air conditioning systems are different from those of ordinary offices or public areas.

The exhaust and exhaust system is one of the large-scale and widely-affected systems throughout the design and construction process.

  Whether the exhaust system is perfect or not directly has an important impact on the environment, the health of the experimental personnel, and the operation and maintenance of the experimental equipment. Excessive negative pressure, gas leakage from the fume hood, noise, etc. have always been a problem for the staff. These problems cause physical and psychological harm to those who work long hours, even those who work in the surrounding management and logistics. The perfect supply and discharge system is a harmonious, safe and healthy workplace. Noise, the number of air changes in the room, and toxic gas residues in the fume hood are all issues of concern.

The main purpose of the VAV control system is to precisely control the ventilation and air conditioning system. The guaranteed temperature, humidity, frequency of ventilation, and emissions of toxic gases can meet design standards under the premise of energy saving. For special requirements such as biosafety, constant temperature and humidity, it is also necessary to use an automatic control system to strictly control the pressure gradient changes between the various.

  The overall design is mainly elegant and fresh, with simplicity, naturalness, fashion and high-end integration. It not only reflects the modern functional requirements, but also greatly meets the ergonomic norms. When the function is cut off, the load-bearing capacity of the building slab is reduced as much as possible, and the inner partition is made of a light partition wall, and the partitioning treatment is performed according to different materials. Smallpox: The general ceiling uses a keel bracket aluminum gusset ceiling that does not collect dust and is not easy to fall off.

Consider a room with liquid and temperament SEM. Ground: For different types of washing rooms, high greenhouses, gas cylinders, mercury-containing experiments, constant temperature and humidity, clean, large instrument rooms, different ground treatment methods are required. In addition, some special requirements such as biosafety, constant temperature and humidity, etc., need to comply with relevant technical specifications.

The design of the instrument placement is one of the key points and difficulties in the design. The placement of experimental instruments may seem simple, but there are actually many factors to consider. Whether the experimental equipment can operate safely and safely, whether it can be properly protected, whether the environmental impact can be reduced to a low level, whether it has an influence on each other, whether the experimenter can use it conveniently, etc. Consider the issues you need to focus on when placing the instrument. Reasonable layout of experimental instruments not only requires designers to have a good understanding of the special requirements of the equipment, itself, the environment, water supply, gas supply, power supply, waste gas exhaust, etc., but also requires designers to have considerable architectural design. And knowledge of construction management.

  Furniture is a kind of special kind of laboratory furniture. Furniture should not only have excellent use functions, but also have a clean and clear appearance and color to improve the indoor environment and reflect the characteristics of the times. The laboratory design, flexibility and serialization of furniture are one of the building elements and one of the basic conditions. In order to meet the needs of various experimental contents, laboratory furniture should satisfy the experimental functionality, robustness, corrosion resistance, and flexibility of installation and arrangement while pursuing the comfortable and safe experimental environment. Furniture is different from household furniture. Its use is often in contact with water, electricity, gas, chemical substances and materials, as well as equipment. Therefore, higher requirements are placed on the structure and material of the furniture. The design and selection of furniture must be emphasized during construction. type.
