燃气中央热水供应系统的设计计算和应用OA

Three types of gas-fired central hot water supply systems:instant heating-type,water stor-age-type,and composite-type are introduced,and the water storage-type gas-fired central hot water system is analyzed.The average hot water flow rates of 5 similar hotels are investigated.The peak water flow rate is in the morning and evening,the valley is during the day,and the minimum hot water flow rate is from night to early morning.By performing segmented fitting,the hot water flow curve of the target hotel is obtained in an"M"shape.Considering that the design hourly hot wa-ter consumption may not necessarily occur within an entire hour,according to the hot water flow curve,com-bined with the integral relationship,the design hourly water consumption can be obtained,and the time range involved may span the entire hour,which improves the guarantee ability of the hot water supply system.The hot water supply system of the target hotel is designed according to the calculated design hourly hot water con-sumption,which proves that the water storage-type gas-fired central hot water system has certain promotion and application value in the commercial field.
