In constructing a cleanroom, it is essential to remove airborne particles, harmful air, bacteria, and other pollutants within a certain space, and to control the indoor temperature, cleanliness, air pressure, air velocity and distribution, noise vibration, and lighting within a specified range. To prevent external contamination from侵入, it is necessary to maintain internal pressure higher than external pressure. In the engineering of cleanroom construction or in air conditioning systems, the requirements for ductwork emphasize both economy and efficiency. The former is reflected in low cost, ease of construction, and low operational costs with a smooth inner surface for reduced resistance. The latter refers to good airtightness, no leakage, no dust generation or accumulation, no contamination, and resistance to fire, corrosion, and moisture. The composition of a cleanroom is made up of the following systems (each is indispensable in the molecular composition of the systems), otherwise, a complete and high-quality cleanroom cannot be formed.

The outlook for cleanroom engineering is very promising, with strong market demand. This is due to the rapid development of industries such as pharmaceuticals and electronic information in our country, which have driven the growth of the cleanroom engineering sector. It's important to note that since the revision of our country's medical GMP-2010 regulations was released, it has not only promoted the development of biomedicine and food chemistry industries but also indirectly spurred the growth of the cleanroom engineering sector. Moreover, the support from relevant parties has greatly enhanced the development opportunities for the cleanroom engineering industry. The 10-grade cleanroom is primarily used for semiconductor industries with bandwidths less than 2 micrometers. Its air purification requirements are second only to the 1-grade, sterile cleanroom, and our country's semiconductor technology is also advancing, with an increasing demand for purity in the future. The higher the relative humidity, the more difficult it is to remove adhesives. In a 100,000-grade cleanroom, however, particles are easily adsorbed to the surface when the relative humidity is below 30% due to the effect of static electricity, and a large number of semiconductor devices are prone to breakdown. The temperature range for silicon wafer production is 35-45%.

The specific requirements for temperature in various processes will be listed later, but as a general principle, due to increasingly refined processing accuracy, the tolerance for temperature fluctuations is becoming narrower. For instance, in the photolithography process for large-scale integrated circuit production, the difference in thermal expansion coefficients between the glass used as the mask material and the silicon wafer needs to be minimized. The rise of cleanroom technology is a phenomenon from the last century, and the cost of cleanrooms may have varied, but the significant role of cleanroom technology today is evident. As products continue to improve, the dependence on cleanrooms in Tongling is also increasing. Level 1: Dust can easily cause chip failure or reduced stability; when metallic dust falls onto an integrated circuit, it may cause a short circuit. When acidic ions in the air fall onto the circuit, they may corrode it, making the cleanroom air conditioning system crucial for the microelectronics industry. Additionally, the production of liquid crystal and optical fibers also requires Level 1 cleanliness.
