■ Clean room decontamination project linkage commissioning
The linkage commissioning is generally carried out in two stages, i.e. the air volume distribution stage and the linkage commissioning stage.
1、Air volume distribution：
The air volume distribution means that the air supply, return air, fresh air and exhaust air volume of each clean room are all adjusted to the design air volume according to the design requirements. Because a clean plant may have more than one air conditioning air supply system and exhaust system, or an air conditioning air supply system to bear the air supply of more than one clean room. Therefore, the air volume distribution and commissioning work is a large workload, long time, patient and meticulous work. Air volume distribution debugging work is also the focus of the entire commissioning work. The common method of air volume distribution debugging uses the standard air outlet method.
Standard air outlet method: a clean room may have several, dozens of air conditioning air supply and return air outlets. Because they are connected to each other, when adjusting the air volume of a certain air outlet air supply, the air volume of other air outlets will also change with it. Therefore, the standard air outlet method is used.
The so-called standard air outlet method is to find the most unfavorable air outlet (the air outlet with the smallest air supply) in all the air outlets before the air volume is distributed, with all the valves opened to the maximum, and take this outlet as the standard air outlet. Set up a monitoring instrument on the standard air outlet to test the air volume change of the standard air outlet at any time. Then adjust the air volume of all other air outlets. Because when adjusting the air volume of any one air outlet, it will affect the change of the air volume of the adjusted air outlet; therefore, when adjusting the air volume of any one air outlet, it is necessary to take the air volume of the standard air outlet as the reference air volume at that time, so that the air volume of all the adjusted air outlets will change synchronously with the change of the air volume of the standard air outlet.
When a clean air conditioning system is responsible for multiple clean room air conditioning, the commissioning should be carried out from the end of the clean room as a unit to the total trunk direction, and the relative relationship amount of air supply to each clean room should be adjusted first, and then, the total valve of the system should be used to adjust the air supply to each air outlet and each clean room to the real design air supply.
2、Commissioning of clean room purification project linkage
The linkage commissioning is carried out after the air volume adjustment and single machine commissioning. Linkage commissioning on the purified air conditioning system and all systems serving the purified air conditioning system, namely: cooling system (chiller, cooling tower, water pump and all accessories on the cooling system), heating system (boiler, water pump and all accessories on the heating system), power supply system (distribution box, inverter……) and automatic control system are all put into operation to assess the system's Comprehensive performance and linkage performance. If necessary, set a certain amount of load artificially in the clean room to assess whether the linkage of temperature and humidity probes, intermediate instruments and actuators is sensitive and coordinated; assess whether the temperature and humidity probes are accurate and whether the accuracy is qualified.
