Clean air conditioning system not only has certain requirements for indoor air temperature, humidity and wind speed, but also has higher requirements for dust content and bacterial concentration in the air; fresh air from outdoor is filtered by filter, mixed with return air from clean room, filtered by primary effect filter, and then treated by constant temperature dehumidification in surface cooling section and heating section respectively After filtering by the medium efficiency filter, it enters the air supply pipe after passing through the humidification section. After noise reduction by the muffler on the air supply pipe, it enters the high efficiency filter at the end of the pipe and then enters the room. Some rooms are equipped with exhaust outlets, which are discharged out of the room. The rest of the air enters the circulation before the primary efficiency filter after mixing with fresh air through the return air outlet and return air pipe.
Clean air conditioning system is divided into fresh air system, primary air return system and secondary air return system according to the form of supply and return air. It is divided into constant air volume system and variable air volume system according to the air volume. It is divided into unidirectional flow and turbulent flow according to the form of supply air flow.
Centralized clean air-conditioning system, in the system, the purification air-conditioning equipment required for single or multiple clean rooms are concentrated in the machine room, and the clean air is distributed to each clean room by air supply duct; decentralized clean air-conditioning system, each clean room in the system is separately equipped with purification equipment or purification air-conditioning equipment; semi centralized clean air-conditioning system, existing centralized purification air-conditioning machine room There are also air treatment equipment scattered in each dust-free room, which is a combination of centralized treatment and local treatment.
The clean air conditioning system consists of heating or cooling, humidification or dehumidification and purification equipment. The auxiliary system includes the air conveying equipment and its pipelines that send the treated air into each dust-free room and circulate it, and the heat and cold sources and their pipeline systems that provide heat and cold to the system.
