With the economic development and improvement of living standards, the current in the electronics, pharmaceutical, food, bio-engineering, medical and other areas of the increasingly clean room requirements, clean technology also developed. It combines the technology, construction, decoration, water supply and drainage, air purification, HVAC and other aspects of technology. In accordance with the standards of the People\'s Republic of China GBJ73-84 \"clean plant design specifications\", and air conditioning system related to the main technical indicators:

Ultra-clean line - ultra-clean production line is actually composed of more than 100 layers of laminar flow clean bench combination, but also through the top of the frame covered with 100 layers laminar flow hood to achieve, mainly to meet the modern industry, photoelectric Industry, biopharmaceutical and scientific research and other areas of the local work area of the needs of cleanliness and design. Its working principle is: through the fan air into the pre-filter, through the static pressure box into the high efficiency filter filter, the filtered air to the vertical or horizontal airflow state, so that the operation area to reach 100 cleanliness, to ensure that the production of Environmental cleanliness requirements.

With the rapid development of China\'s information technology, in recent years, large-scale, high-level clean plant (or super clean factory) have been built. This plant is characterized by a large area of clean production areas (or technological layer), the region arranged a specific craft area and the central corridor, the key set of high cleanliness of the product walkway and micro-environment devices. The upper layer of the huge space used to arrange the air duct or used as a hydrostatic tank; its quasi-clean area (or facilities layer) is used to arrange from the clean area out of the equipment, process facilities and central public facilities Pipe network; between the facility layer and the process layer with a return air space; clean area around the shaft for the return air. By the independent fresh air handling system, focus on the fresh air directly to the internal state of the dew point, and then into the circulating air system. The dry air duct is provided in the circulating air passage to handle the sensible heat load in the room. The difference is only the design of the cycle of wind system ideas, which have a corresponding solution.

In the pharmaceutical, electronics, food and other industries of the rapid development of today, these industries on the production plant, production processes and production environment requirements are getting higher and higher. Clean the plant as a solution to medicine, food, high precision instruments sterile dust production premise to ensure that, follow the pace of the times came into being, so its fire design can not be ignored. The reason is that clean plant is a completely closed environment, import and export has a strict control requirements, not free to set up clean room access door, work more free to open the door at random. Personnel need to enter and exit the clean room, must go through the air shower and other staff self-cleaning equipment, goods into the clean room, must be through the cargo Lin room / air shower channel and other equipment can access. Faced with such a complex access to the process, clean room fire there is a hidden danger? This is certainly some, then, how to solve the fire room fire hazards?
