Division of clean room air conditioning system

(a) purification of air conditioning system division principle 1, cleanliness, temperature, humidity and its accuracy of the same or similar clean room should be divided into a purification air conditioning system.Easy to control cleanliness and temperature and humidity.2. The clean room close to each other should be classified as a system, which can reduce the length of system pipelines and the crossing of pipelines. 3. When conditions permit, the mixed flow purification air conditioning system can be composed of 4, 5 unidirectional flows and 6, 7 and 8 non-unidirectional flows. 4, clean room should not be combined with the general air conditioning room as a system. 5, use the law and use time is not the same as the clean room is not suitable for a purification air conditioning system. 6, dust production, heat, harmful substances, noise room should be designed as a separate system. 7. Rooms that are highly toxic and cause fire and explosion after mixing shall not be combined into one purification air conditioning system. 8, there are highly toxic and inflammable and explosive a, b room should be a separate system, and should not return the air dc system. 9, a purification air conditioning system is not easy to be too large.In general, the purification air delivery volume should not exceed 100,000 m; otherwise, the air treatment equipment is too large, noisy, the return air duct is large, occupies a large space and area, and the use is not flexible. 10, clean air conditioning system division should also consider the air duct, return duct, exhaust duct and water, electricity, gas and other pipelines layout, as far as possible to make a reasonable, short, easy to use management, reduce the intersection and overlap. 11. The heat, humidity and purification treatment of fresh air in the air conditioning system can be centralized or decentralized The principle of dividing the local exhaust air system of the process equipment 1. The partial exhaust air system of the process equipment should not be too large, and the exhaust air points of each exhaust air system should not be too much, so that the exhaust air management and adjustment are convenient and the exhaust air effect is good. 2. One exhaust air system should not cross two or more purification air conditioning systems. 3. The exhaust air which produces highly toxic, explosive, fire, condensation, crystallization and harmful substances after mixing shall not be combined into one exhaust air system. 4. The exhaust air of different rooms and equipment should not be combined into one exhaust air system. 5.Comparison and selection of air supply type of clean room purification air conditioning system (a) purification and air conditioning air supply combined air supply type, usually also known as the centralized type of air supply.The scheme of purifying air conditioning units (air handling units AHU) set in air conditioning room, purification of all air conditioning supply air purification were conduct...
