Clean air conditioning systems can be encountered in many places, in factory workshops, hospitals, and even in some high-class restaurants. Clean air conditioning system is an indispensable part of pharmaceutical clean engineering. The quality of clean air conditioning system can directly affect the quality of products and the asepsis of the space environment. Then today Xiaobian will introduce the working principle of clean air conditioning system, common problems and corresponding treatment methods in detail. The principle of a clean air conditioning system is to send clean air to the room by the air supply port. After the dust bacteria produced indoors are diluted by clean air, they are forced to enter the return air pipeline of the system by the return air port. In the mixing section of the air conditioning equipment, the fresh air is mixed with the filtered air introduced from the outdoor, and then sent to the room after being treated by the air conditioner. This repeated circulation of indoor air can control pollution at a stable level for a considerable period of time.

The working principle of clean air conditioning system, the composition of clean air conditioning system:

1, the composition of clean air conditioning system: mainly composed of combined air conditioning unit, refrigeration system, steam system.

2, combined air conditioning unit: by a number of functions according to the need to combine into the air treatment unit, usually used in the functional section: fresh air filtration, air mixing, primary filtration, table cooler, heater, fan, filter, humidifier, return fan and other basic combination units.

3, Refrigeration system: mainly by chiller, cooling tower, water replenishment system, cooling water circulation pump, frozen water circulation pump.

4, steam system: induced draft fan, slurry pump, boiler, dust pump.

Classification of clean air conditioning systems:

1, centralized clean air conditioning system: in the system of a single or more clean rooms needed to purify the air conditioning equipment are concentrated in the machine room, with the air supply pipe will be clean air distribution to each clean

Clean room.

2. Decentralized clean air conditioning system: each clean room in the system is separately equipped with purification equipment or purification air conditioning equipment.

3, semi-centralized clean air conditioning system: in this system, there are both centralized purification air conditioning room, and scattered in the clean room of the air treatment equipment, is a centralized treatment and local treatment combined form. Clean air conditioning system is a very important part of the control of outdoor substances that affect the clean environment in clean rooms, such as dust, smoke, microorganisms, etc., which are used in medicine and health, food processing, microelectronics engineering.
