How to ensure the cleanliness of air-conditioned rooms

In air-conditioned rooms, ultra-purification workshops, electronic computing rooms and other places that have certain requirements for cleanliness, the following measures should be taken to ensure the cleanliness of the room:

【1】Maintain the positive pressure value of the air-conditioned room. If the room has negative pressure or the positive pressure value is lower than that of the adjacent room, the air in the outdoor and surrounding rooms will seep into the door and windows. Especially in the purification air conditioning system, the higher purification level is higher than the positive pressure value of other rooms.

【2】It is necessary to ensure the rationality of the airflow organization in the air conditioning room. If the airflow tissue is destroyed, not only will the indoor temperature distribution be affected, but also due to excessive snail flow, unclean airflow near the wall corners and ground spreads to the indoor working area. Therefore, the arrangement of the equipment of the workbench in the air-conditioned room should take into account the rationality of the airflow organization. The equipment cannot block the return air outlet, and the return air outlet blinds are strictly prohibited from moving randomly.

【3】The room must be purified to have three levels of filtration: coarse, medium, and high-efficiency filtration. We must strengthen the management of air conditioners for purification. Staff should abide by the systems and operating procedures to ensure that the indoor hygiene meets the purification requirements.

【4】Refrequently or regularly clean the air filter, and clean the medium-coarse and medium-effect foam plastic filters. When the final resistance of the medium-effect filter is twice the initial resistance or a limit value, it should be cleaned. When the resistance of the high-efficiency filter is too large, it should be replaced. After cleaning the foam filter, it should be measured.

【5】Keep the air conditioning processing equipment and the air conditioning room clean.

【6】Dust content and positive pressure value in the room are regularly measured.
