The purification engineering profession is an evergreen industry that serves high-tech, national economy and people's livelihood. The development of cutting-edge technology and the improvement of the quality of residents' daily life depend on the development of purification technology as its secret support. In recent years, with the gradual progress of people’s living standards, the related technologies of dust-free workshops have gradually expanded from service technology and industrial high-end to serving general work and life fields, in all aspects of food production and circulation, high-end equipment production, high-end commercial office buildings, Large-scale data centers, large-scale event venues, and even cosmetics and cosmetics have been widely used.

Dust-free workshop engineering refers to the provision of effective control of pollutants such as particles, harmful air, bacteria, temperature, humidity, noise, illuminance, cleanliness, indoor pressure difference, air velocity and air distribution, vibration, and static electricity according to customer requirements. Clean and controlled space where all objectives meet the requirements of safe production. The primary effect of the dust-free workshop is the cleanliness of the environment required for product production (such as silicon chips, etc.) and services, as well as various objectives such as temperature and humidity, micro-vibration, noise, and illuminance, so that related products and services can meet The production and operation are carried out in the required, controlled, and outstanding environmental space, so as to achieve the goal of improving the yield of product production and improving and improving the quality of related services.

The dust-free workshop project mainly includes three links related to the planning, construction and operation of the dust-free workshop. Quality comes from planning, and planning is the center. The construction of purification projects is different from general construction projects, including enclosure structure (commonly known as "house in room"); air conditioning purification system; power supply, automatic control, weak current system; pure water, special gas, material supply system; waste gas, wastewater Processing system and related equipment. Operation management includes: real-time inspection, personnel training, and equipment maintenance to ensure that the controlled production and scientific research environment continues to meet the requirements. The three links cover three occupancy states: empty state, static state, and dynamic state; environmental control combines the concepts and procedures of risk assessment and production certification; plus the cross-professional, cross-professional, and cross-disciplinary characteristics of clean technology: make it dust-free Increased difficulty and complexity of workshop engineering. Davis therefore, for the clean room engineering profession, optimize planning, coordination and control of on-site construction environment, accumulation of experience in engineering-related technical details, understanding and realization of customer needs, and the degree of preparation and response to planning changes, etc. Both are important targets for measuring the ability of the construction team in the clean room.
