Clean room purification air conditioning system
The clean room exhaust system should take measures to prevent the backflow of the outdoor air; for the exhaust system containing water vapor and condensable substances, the slope and the discharge port should be set; the disinfection and sterilization method of the clean room should use the purification air conditioning system When used as ventilation facilities, corresponding disinfection and ventilation facilities should be configured; the ventilation systems for different purification air conditioning systems and the ventilation systems for areas that emit dust or harmful gases should be set up separately. A reasonable pressure gradient should be maintained between the personnel purification rooms. Unless there are special requirements, the air flow should be ensured from the clean area through the personnel purification room to the air flow direction of the unclean area; the static level of the rear section of the personnel purification room should be corresponding to it. The level of the clean area is the same, the front section should have an appropriate clean level, and the changing of shoes and coats can be located in the clean area; the personnel purification room should have sufficient ventilation; the special pharmaceutical production area, in order to block the air outside the production area In the room for personnel purification, positive or negative pressure air locks should be set as required.
The opening and closing of supply air, return air and exhaust air should be interlocked. The interlocking procedure of positive pressure clean room is to start the supply fan first, then start the return fan and exhaust fan, and the interlocking procedure should be reversed when closing; The system should maintain continuous operation and maintain the corresponding cleanliness level; during non-production periods, the purification air conditioning system can use low-frequency operation and other modes, but it should still maintain the corresponding pharma clean room level and the positive pressure to the surrounding low-level cleanliness area, and shut down for any reason When the air purification system is turned on again, the necessary tests should be carried out to confirm that it meets its specified cleanliness level requirements. The number of air changes in the accident exhaust area should not be less than 12 times/H; the ventilation components and equipment of the accident exhaust system should meet the corresponding anti-corrosion requirements; the electrical switches of the accident ventilator should be set in the clean room and the clean room, which are easy to operate. Location; when the site with accident exhaust does not have natural air intake conditions, a supplementary air system should be set up at the same time, the supplementary air volume should be 50%-80% of the exhaust air volume, and the supplementary fan should be interlocked with the accident exhaust fan. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and sterile workshops.
When mechanical smoke exhaust is installed in the factory building, a supplementary air system should be installed at the same time, and the amount of supplementary air should not be less than 50% of the exhaust volume. Under the smoke warehouse; the smoke exhaust and air supply openings of the clean room should be equipped with anti-leakage measures, and the air inlet and outlet of the interconnected smoke exhaust and supply air systems should be provided with measures to prevent insects from entering; when the noise of the purification air conditioning system exceeds the allowable value , measures such as sound insulation, noise reduction and vibration isolation should be taken, and the noise reduction facilities shall not affect the purification conditions of the clean room. The clean room should be equipped with a device indicating the pressure difference: between the clean room and the non-clean room; between the clean rooms of different air cleanliness levels; the air lock of the material purification room and the changing rooms of different cleanliness levels of the personnel purification room. In the production area of u200bu200bthe same clean level, it is necessary to maintain a relatively negative pressure or positive pressure in the more important operation room; the mechanical method is used to continuously transfer materials into and out of the clean room.
A one-way flow device with a cleanliness level of A-level area, when the one-way flow device has a large area and uses indoor circulating air to operate, measures should be taken to reduce the temperature difference between the air cleanliness level A-level area and the surrounding indoor environment. The temperature in the air cleanliness grade A area should not exceed the indoor design temperature by 2°C, and should not be higher than 24°C; the unidirectional flow device of the air cleanliness grade A should use the lower part of the side wall or the ground grille to return the air; local air If necessary, the outer edge of the one-way flow device with the cleanliness class A should be provided with a fence, and the height of the fence should be lower than the operating surface; when the one-way flow device adopts a combination of fan filter units or laminar flow hoods, the air supply volume should be adjustable; The one-way flow device shall be set up to facilitate installation, maintenance and replacement of the air filter. The air handling unit should have good air tightness. When the static pressure in the unit is maintained at 1KPa, the air leakage rate should not be greater than 1%; the inner surface of the air handling unit should be smooth, corrosion-resistant and easy to clean; the air handling unit should have good thermal insulation performance, No condensation shall be allowed on the outer surface; the air supply fan of the air handling unit should be selected according to the total air volume and total resistance of the purifying air conditioning system. Speed u200bu200bcontrol device; the overall structure of the air handling unit should have sufficient strength, and the unit casing should not be deformed during transportation, installation and operation.
