307 workshop steam is used for: drying oven, coating machine, fluidized bed, hot water heating, air conditioning system and other equipment. When deviation occurs, only air conditioning system equipment uses steam. According to H5-TM-14055 Technical Manual of Air Conditioning System, during production, the temperature control range is 18℃-26℃, and the humidity control range is 45%RH-65%RH. When the temperature and humidity of the room exceed the control range, an alarm will be given, and all functional rooms in the clean area will give an alarm during steam shutdown. H5-TM-14055 Technical Manual of Air Conditioning System stipulates that deviation treatment is required when the room temperature and humidity alarm time is greater than or equal to 60 minutes, among which the low humidity alarm in 2432 transfer room was submitted for deviation treatment on February 3, 2021, and the temperature and humidity alarm time in other rooms is greater than 60 minutes, so there is no production on site, only materials are stored in the transfer room (2432; 2308)。 See D-TZ-FDF-307-21001-R for details.
