How to build a constant temperature and humidity laboratory?
Category: Industry News
Constant temperature and humidity laboratory How should the construction be carried out?
Early planning: The positioning and planning of the constant temperature and humidity laboratory is the basis of conventional laboratory construction. The planning scheme of the constant temperature and humidity laboratory includes laboratory building planning and laboratory process planning, which requires a lot of preliminary research work. It is necessary to clarify its own needs and future development direction, and to conduct a general investigation of the constant temperature and humidity laboratories built by relevant units, and learn from their experience and lessons.
2. Selection of design company: When selecting a constant temperature and humidity laboratory design company, it is necessary to strictly examine its design, R&D, production and construction capabilities and qualification level. It is best to conduct on-site inspections of its completed projects and the company's location. It is best to choose a nearby construction unit.
3. Plane layout design: Plane layout design refers to the reasonable allocation of space according to the needs of the constant temperature and humidity laboratory, optimization of the layout and placement of instruments and equipment, and full consideration of the direction of personnel flow and material flow, etc. Ensure the subsequent design of water, electricity, and wind, rather than a simple combination of instruments and equipment.
4. Laboratory power distribution system: The instruments and equipment in the constant temperature and humidity laboratory have complex requirements for the circuit, and many instruments and equipment have special requirements for the circuit. For the design of the power distribution system, not only the existing instruments and equipment should be considered, but also the development plan of the laboratory for several years should be considered, and the reservation of the power distribution system and future circuit maintenance should be fully considered. In order to ensure the reliability of power supply, uninterrupted power supply or dual-line design should also be considered. The capacity of the uninterrupted power supply should meet the actual needs and ensure a certain expandable range to meet the needs of future development.
5. Laboratory water supply and drainage system: The pipelines of the laboratory drainage system should be resistant to acid and alkali corrosion and the melting of materials by organic reagents, and should be made of PPR or other materials. At the same time, the scheme should be determined according to the nature, flow rate, and discharge law of wastewater, combined with outdoor drainage conditions. Due to the complexity of the sewage pipelines in large laboratories, necessary measures should be taken to prevent pipe blockage and leakage.
6. Laboratory ventilation and exhaust system: The exhaust system of the constant temperature and humidity laboratory is one of the largest and most influential systems in the entire process of laboratory design and construction. Among them, laboratory noise, room ventilation frequency, pressure difference, and residual toxic gases in the fume hood are all worthy of attention. In addition, ventilation and exhaust equipment should be considered in the sample room and reagent room to avoid the smell from the samples affecting the environment.
7. Selection of laboratory equipment: The selection of constant temperature and humidity laboratory equipment mainly involves factors such as desktop material, cabinet structure and material, and color matching. For example, acid-resistant and alkali-resistant ceramic countertops should be used in the pretreatment room, and chemical countertops should be used in the instrument room. The structure of the table and cabinet is mainly divided into three types: steel-wood, aluminum-wood, and all-steel. The support of the test bench can be divided into C-shaped and back-shaped, which should be determined according to the needs of each unit. The layout, type, and quantity of cabinets in each room should also be fully considered. Side tables, center tables, high cabinets, and hanging cabinets should be properly matched to avoid inconvenience in future work. In addition, some details should also be considered, such as the reasonable configuration of computer positions, to avoid inconvenience in future use.
