The temperature and humidity requirements of the purification workshop are different from the temperature and humidity requirements of general central air conditioners. It not only needs to meet the requirements of human comfort, but also needs to meet the requirements of the product production process. For example: in the lens production workshop, the humidity should not be too high, too high will cause the lens to fog, which is not conducive to the production of the product; in the food production workshop, too high humidity will cause the product to deteriorate. At the same time, the temperature should not be too high. If the temperature is too high, the product will be polluted if the producer touches the product after sweating, which will reduce the qualified rate of the product.
However, it is not that the lower the humidity in the purification workshop, the better. Too low humidity will generate static electricity, which will have an adverse effect on electronic products and reduce the product qualification rate. If static electricity is generated in the manufacturing workshop of the electronics industry, it will cause a short circuit; the relative humidity of the purification workshop of the electronics industry should not be lower than 30%. In order to reduce the generation of static electricity, the relative humidity of the anti-static area of the purification workshop should not be less than 50%. At the same time, the temperature of the cleanliness workshop is not as low as possible. The lower the temperature, the higher the construction cost of the purification workshop and the higher the energy consumption for operation. Different industries, products produced have different requirements for temperature and humidity. For example, if there are no special requirements in the dust-free workshop of the electronics factory, the temperature is controlled at about 22 ℃, and the relative humidity is controlled between 55-60%RH; SMT constant temperature The temperature and humidity standard of the constant humidity workshop: temperature, 24±2℃; humidity, 50±10%.
So should all purification workshops be designed as constant temperature and humidity purification workshops? the answer is negative. The temperature and humidity of the purification air-conditioning system must be designed based on the requirements of the production process. If the production process does not require temperature and humidity, it should be based on the comfort of the human body. Because the constant temperature and humidity clean air-conditioning system needs to be equipped with heaters, humidifiers, and PLC automatic control systems, it increases the construction cost, operating cost (increased electricity consumption), and maintenance cost of the purification workshop.
The above is the application scope of temperature and humidity in the purification workshop and the precautions for purchase introduced by Nesta, so please feel free to contact us for more information about temperature and humidity control in the purification workshop.
