Therefore, the energy-saving measures of the general air-conditioning system, such as the enclosure structure, the insulation system, the variable flow exhaust air heat, the selection of refrigerator water pump fan equipment, etc., can be applied to the energy-saving design of the air-conditioning system of the clean workshop. At the same time, the air-conditioning system of the clean workshop has its own characteristics, and it also has its own system energy-saving characteristics and methods.
1. The clean air volume is separated from the air volume of the air conditioner.
The function of clean room air supply is that the air conditioner air is treated with temperature and humidity to meet the temperature and humidity requirements of the clean roomThe second is to purify the air filtration to meet the cleanliness requirements of the clean room. In general, the purifying air volume is too large to exceed the air volume of the air conditioner. If the air supply of the air conditioner plays the role of air conditioning and purification at the same time, that is, the air volume of the air conditioner and the air volume of the purification are not separated, all the return air must be processed by the air conditioning box, and when the large air volume passes through the air treatment equipment, the resistance will be great, and the energy consumption of the fan will increase sharply.
2. Reduce the air volume of the air conditioning system.
The high requirements for cleanliness of the PCB dust-free workshop have created a large air volume of its air conditioning system. From the knowledge of aerodynamics, it can be seen that the energy consumption of power equipment such as fans is proportional to its air volume, so reducing the air volume of the system is of great significance for the energy saving of the air conditioning system of the clean workshop.
3. Reduce the amount of fresh air.
Because the fresh air load accounts for a large proportion in the air-conditioning system of the PCB dust-free workshop, it is of great significance to reduce the energy consumption of the clean air-conditioning system by reducing the fresh air volume.
4. System air volume control.
The fan system also operates as usual during non-productive hours, which not only consumes energy, but also has high mechanical wear and tear, which seriously affects the life of the equipment. In fact, when no one goes to work in the clean room, the main pollutants are gone, and the exhaust system only needs to discharge the residual harmful substances with a smaller exhaust air volume, therefore, the air supply volume can also be reduced accordingly, as long as the positive pressure of the clean room can be maintained, in addition, even in the production state, the use of the exhaust system is not the same, therefore, according to the real-time situation of the exhaust system, the air supply volume can be adjusted in time, which can be very effective in reducing the energy consumption of the ventilation and air conditioning system.
The energy consumption of the PCB dust-free workshop air-conditioning system is very high due to its large air volume, fresh air load, high resistance and other characteristics, which is several times that of the general air-conditioning system, therefore, the energy-saving design and operation of the clean room air-conditioning system has a strong necessity and potentialBy reducing and optimizing the airflow organization, separating the purified air volume from the air conditioning air volume and reducing the clean area, the air supply volume of the system can be significantly reducedReduce the fresh air volume of the system by setting up the system exhaust hood and other optimization configuration measures;The use of automatic control and enhanced management can optimize the air volume operation of the system and significantly reduce the energy consumption level of the system.
