- Abstract:
- According to Standard for Design of Building Water Supply and Drainage (GB 50015-2019), the square root method is used to calculate the design peak flow of the water supply for the dormitory with a private bathroom in the room, while the design hour flow of the hot water consumption of the fixed time hot water supply system is calculated according to the simultaneous water supply percentage in water-intensive-use building. In view of the problem of how to select a formula for calculating the design peak flow of the hot water supply when there is a fixed time hot water supply system in the dormitory with a private bathroom, the relationship between the design peak flow of hot water supply calculated by square root method and that converted by the design hour flow calculated by the simultaneous water supply percentage method was analyzed, and found that the calculation result of square root method was small and unreasonable when the number of showers and washbasins was more than 340. Therefore, it is suggested to calculate the design peak flow of hot water supply by the simultaneous water supply percentage method, and the value table of percentage of simultaneous water supply for sanitary appliances was provided.
