In order to prevent cross infection and dust accumulation during the construction of the purification project, the decorative materials for ceiling, wall and floor should be wear-resistant, dust-free, easy to clean and corrosion-resistant. In the purification project, it is required that the junction between kick and ground be rounded. In order to avoid accidents, it is also required that the sunny corner be rounded, and the wall be made of collision-proof plate. Exposed wood and gypsum materials are easy to absorb moisture, deform, crack, accumulate ash, grow bacteria and store bacteria, so it is required that these materials should not be used in purification engineering. In order to prevent air pollution, hanging automatic push-pull doors should be installed in the doors entering the workshop to reduce the interference of external air flow and avoid the occurrence of groove fouling on the ground.
Purification engineering requires special and strict air-conditioning system. It is forbidden to use common fan coil units or air conditioners in purification engineering, to avoid mildew and bacteria, and to emphasize humidity control in the whole clean workshop. Fresh air volume shall be determined according to regulations and its maximum value shall be taken. Air conditioning pipes should be short, straight and smooth, minimizing fittings, using pipes with good air flow performance and small eddy current area and static pressure box, piping system should not use hoses. The air supply outlets located on the top of the test-bed should be centralized in the class I-III clean workshop, so that a certain area including the test-bed should be located in the main stream area formed by the clean air flow. All clean workshops shall adopt bilateral lower return air, and shall not adopt four corners or four sides return air. Indoor return air is adopted, and no residual pressure valve is set to return air to corridor. The return air in this room is solved by circulating the return air pipe in this room.
The water supply in the purification project needs both hot and cold water, water supply should be uninterrupted, water quantity and pressure should be guaranteed, and water quality should be reliable. Clean workshops with high requirements for water quality standards should install water disinfection sterilizers, such as bacteria filters and ultraviolet rays, in addition to drinking water standards. Water supply pipes cannot be directly connected to any sanitary appliances and equipment that may cause pollution unless air partition devices or effective backflow preventive devices are left in the connection system. The floor drain should not be installed in the purification project. The floor drain should be set beside the brushing room and toilet utensils, and must be encrypted and sealed. In order to prevent the blockage of drainage pipeline, the daily maintenance can be reduced by increasing the diameter of drainage pipeline in purification project.
Purification engineering
Because the construction of air-conditioning purification system and envelope structure is not undertaken by a unit in the construction of purification project, which causes hidden dangers to the quality of the project, it is especially emphasized that the construction of the project must take air-conditioning purification as the core and conduct the construction in a unified way. In order to ensure the quality, after the acceptance of the building where the purification workshop is located, it should also be acceptance separately. Because the clean workshop is a multi-functional integrated whole, the single index of air cleanliness or bacterial concentration can not reflect the overall performance of the purification project which can be put into use; and because the completion acceptance mainly examines the construction quality, the comprehensive performance evaluation mainly examines the design quality, so it can not replace each other, and only the purifier. A comprehensive assessment can be made only after the project has been completed and accepted.
