The contents involved in laboratory planning and design mainly include plane layout, water source, electric circuit, air circuit, and ventilation.
1. Floor plan
Determine the overall floor plan of the laboratory and clarify the layout of the laboratory. The laboratory is required to be effectively isolated from the office area, the functional areas are clearly divided, the experiments do not interfere with each other, and the evacuation channels are unblocked.
2. Water source
The water supply in the laboratory follows the principle of convenient access nearby, and sets up sinks where necessary. In particular, there must be a sink next to some instruments that require an external water source to facilitate water intake.
3. Circuit
The circuit design must consider the size of the overall power, the requirements of three-phase power, and the requirements of the stability of special instruments. In order to facilitate operation and meet the requirements of safety management, laboratories generally require independent control switches.
A correct and good grounding system is very necessary for the normal, reliable and safe operation of analytical laboratory instruments.
4. Air path
There are two modes of air supply: centralized air supply and independent air supply. The gas pipeline should be laid out along the wall to facilitate installation and maintenance.
5. Ventilation system
Ventilation is an indispensable part of laboratory design. In order to reduce the injury of experimenters, the laboratory must be ventilated.
There are two ways to ventilate the laboratory, namely local exhaust and full room ventilation. Local exhaust is to discharge nearby harmful substances after they are produced. This method can discharge a large amount of harmful substances with less air volume, and is widely used in modern laboratories. For some experiments, local exhaust air cannot be used, or when local exhaust air cannot meet the requirements, full room ventilation should be used. The focus of the ventilation system is the determination of the position of the air inlet and outlet and the pre-buried of the air outlet.
