In air-conditioned rooms with certain requirements for cleanliness or ultra-purified workshops, electronic calculation rooms, etc., the following measures should be accepted to ensure the cleanliness of the rooms.
【1】Keep the positive pressure value of the air-conditioning room. If the room is flooded with negative pressure or positive pressure value is lower than the neighboring room, outdoor and surrounding room air will be seeped in by the door and window seams, especially in the purified air conditioning system, purification grade high to be higher than the positive pressure value of other rooms.
【2】To ensure that the airflow organization of the air conditioning room is reasonable. If the airflow organization is damaged, not only the indoor temperature diffusion is affected, and due to excessive snail flow, so that the corners of the walls, the ground around the unclean airflow spread to the indoor business area. Therefore, the air conditioning room in the business desk, the deployment of equipment to think about the airflow organization of the reasonableness. Equipment can not cover the return air outlet, the return air outlet louvers are strictly prohibited to move.
[3] Purification room must ensure that there are three levels of filtration: coarse, medium, and high efficiency filtration. To enhance the governance of purification air conditioning. The staff should comply with the system and operating procedures to ensure that the indoor hygiene to purification requirements.
【4】 Wash and replace the air filter frequently or regularly, and the coarse and medium-effect foam filters should be washed frequently in the new air. When the final resistance of the medium-effect filter is two times the initial resistance or limit value, should be held to wash. When the resistance of high efficiency filter is too large, it should be replaced. After the foam filter is washed, it should be measured.
【5】Keep the air conditioning disposal equipment, air conditioning machine room clean.
【6】 Periodically measure the dust content and positive pressure value in the room.
