Laboratory Construction Planning Criteria

Laboratory construction includes the renewal of technology and equipment, the increase of researchers and the improvement of the capacity of existing researchers. The principle of laboratory construction is to meet the needs of optimizing the business process of laboratory work and daily management. The design takes into account the process flow of the laboratory, the choice of location of special laboratories and function rooms, the specific environment of the upper and lower floors within the building, the building structure and other factors.

Introduction of the contents of the standard program for laboratory construction

In recent years, laboratory construction mainly relies on the state's appropriation, because of the slow development of science and technology, the state has raised the issue of laboratory construction, and thus set up national key laboratories and so on, and laboratory construction also mainly refers to the state's scientific research funding support for these laboratories.

Laboratory construction standard program decoration design

The overall design is based on light, fresh tones, simple, natural, fashionable, high-grade into one, which not only reflects the functional requirements of modern laboratories, but also greatly meets the norms of ergonomics. In the laboratory function partition, as far as possible to reduce the load-bearing of the building floor, the laboratory partition selection of lightweight partition wall, according to the laboratory of different partition processing using different materials.

Ceiling: general laboratory ceiling with no dust collection, not easy to fall off the keel support aluminum button board ceiling. Some instruments need to be silent, the ceiling of the choice of sound-absorbing ceiling. Lighting illumination using embedded dust-proof light panels 30Wx3, work area illuminance & gt; 450Lux, aisle illuminance & gt; 200Lux.

Laboratory noise: according to OSHA and ADA specifications, the noise in the laboratory should not be higher than 60 dB. Consider rooms for liquid and gas scanning electron microscopy.

Laboratory floor: For different kinds of laboratories such as washing rooms, high temperature rooms, gas cylinder rooms, laboratories containing mercury experiments, constant temperature and humidity laboratories, clean laboratories, large instrumentation rooms, etc., different floor treatments are required.

Additionally on some such as biosafety laboratories, constant temperature and humidity laboratories and other special laboratories, the decoration needs to follow the relevant technical specifications.

Laboratory construction standard program power distribution engineering design

Laboratory power distribution project is based on the specific requirements of the experimental instruments and equipment, through the professional designers to synthesize a variety of factors to complete the design, and the ordinary building is very different. Because, the laboratory instruments and equipment on the circuit requirements are more complex, and not usually thought of as long as the maximum voltage and maximum power requirements can be met. In fact there are many instruments and equipment on the circuit have special requirements (such as electrostatic grounding, power failure protection, etc.).

In the process of engineering and construction found that most users in the laboratory design and construction of the early stage, are not fully considered the special requirements of the laboratory power, and even some users and design units that the laboratory of the power consumption and general office similar. This brings a lot of trouble to the later operation of the laboratory.

The design of the power distribution project, not only to consider the existing instrumentation, but also to consider the laboratory several years of development planning. Give full consideration to the reservation of the power distribution project and the future maintenance of the circuit and other issues.

Laboratory construction standard program air conditioning system design

Summer air conditioning indoor calculation parameters for general laboratories: temperature 26 ~ 28 ℃, relative humidity less than 65%. Specialized laboratory air conditioning indoor calculation parameters should be determined according to process requirements. The main role of the air conditioning system is to control the temperature and humidity of the laboratory. Air conditioning system and laboratory ventilation system with the laboratory to really effectively ensure that the temperature and humidity of the laboratory and the effective control of room pressure. In short, the laboratory on the air conditioning system requirements, different from the ordinary office or public **** area of the air conditioning system, has its own particularity.

Laboratory fire system design

Laboratory is a special environment, the requirements of fire relative to ordinary office buildings is much higher. Laboratory designers should be based on the specific circumstances of the laboratory (equipment investment and process characteristics, experimental process requirements, the type of stored samples and reagents, the characteristics of the laboratory building, etc.), the use of different fire protection measures to ensure fire safety in the laboratory.

Laboratory drainage system design

Water supply system selection: according to scientific research, production, life, fire and other aspects of water on water quality, water temperature, water pressure and water requirements, combined with the outdoor water supply system and other factors, from the technical and economic indicators to determine after comparison. Water quota, water pressure, water quality, water temperature and water conditions shall be determined according to the process requirements. Water pipes are laid under the floor by the civil contractor through pre-embedded pipes and led to the designated position of the center stage; for the side stage, water pipes are buried in the wall by the civil contractor and led to the designated position. The rest of the work is done by the laboratory construction unit.

Pure water system: water quality to meet the GB/T6682-1992 "analytical laboratory water specifications and test methods" in the provisions of the second level of water requirements. Pure water system, resistivity ≥ 5MΩ - cm. ultrapure water quality requirements: resistivity ≥ 18.2MΩ - cm, 25 ℃. In addition to the pipeline for pure water delivery problems, but also to meet the relevant standard requirements.

Laboratory gas cylinder room design

Laboratory gas is dangerous and complex, for different laboratories, the gas should be from the layout, classification, fire, power distribution and other aspects of special consideration.

Laboratory gas supply and exhaust design

Laboratory operation of many devices require a variety of gas supply, but also produce exhaust gas. How to solve the problem of gas supply and exhaust both safely and conveniently is one of the problems that have been plaguing the laboratory staff. The traditional way of gas supply in the laboratory is to use gas cylinders placed next to the instruments and equipment, dangerous gas cylinders placed in the gas cylinder cabinet. Exhaust is discharged directly into the laboratory or through a simple pipe to the window. In the development of the laboratory, with the increase of laboratory equipment, the laboratory is often densely covered with a variety of pipes and gas cylinders. Handling them in this way creates both a very significant safety hazard and an unsightly appearance.

The right solution for laboratory supply and exhaust is to look at the laboratory supply and exhaust as a system. This system should take into account the safety, convenience, day-to-day management of the laboratory, the replacement of gas cylinders and other issues, while focusing on the future development of the laboratory, for special gases should also consider special technical solutions.

Laboratory automation system design

The main purpose of the VAV control system is to accurately control the ventilation and air-conditioning system of the laboratory, to ensure that the temperature, humidity, number of air exchanges, as well as the emission of toxic gases, etc. in the laboratory can meet the design standards under the premise of the most energy-saving.

The biological safety laboratory, constant temperature and humidity laboratory and other special requirements of the laboratory, but also need to use the automatic control system to strictly control the pressure gradient between the laboratory changes.

Laboratory exhaust system design

Laboratory air supply and exhaust system is the entire laboratory design and construction process of the largest and most extensive impact of one of the systems. The supply and exhaust system is perfect or not, directly on the laboratory environment, laboratory personnel's health, operation and maintenance of laboratory equipment and other aspects have an important impact.

Excessive negative pressure in the laboratory, fume hood gas leakage, laboratory noise and other issues, has been a problem for laboratory staff. These problems have caused physical and psychological harm to the personnel working in the laboratory for a long time, and even the management and logistics personnel working around the laboratory.

A laboratory with a well-developed supply and exhaust system is a workplace with a harmonious, safe and healthy environment. Laboratory pressure, noise, the number of air changes in the room, airflow organization, fume hoods toxic gas residues are all issues of concern.

Laboratory instrument placement

The design of laboratory instrument placement is a laboratory design is one of the key points and difficulties. The placement of laboratory equipment may seem simple, but in fact there are many factors to consider. Whether the experimental equipment can be good and safe operation, whether it can be properly protected, whether it can minimize the impact of the environment on the degree of their influence, whether there is an impact on each other, whether the experimental staff can be convenient to use and so on, are in the consideration of the laboratory instrument placement need to pay attention to the issue of location. Reasonable arrangement of laboratory equipment, not only need to designers of the equipment itself, the environment, water supply, gas supply, power supply, waste liquid emissions and other aspects of the special requirements of a very good understanding of the outside, but also need to designers with a considerable wealth of knowledge of architectural engineering design and construction management and other aspects.
