摘
随着人们生活水平的提高,对建筑环境提出了更高的要求;另一方面,环境污染、资源短缺的问题日益严重。供热作为建筑能耗的主要承担者,面临着节能环保的巨大潜力与压力。
This paper mainly focuses on the design of heating system, heat exchange station for 9th Building and community first-level heat network engineering design of Mudanjiang Guohua Community. In the design of household heating system.First, the heat load of each floor of Building No. 9 is calculated. Based on consideration of the radiator pressure and system vertical misalignment, different heating zones are delineated.The mechanical hot water heating system.was adopted,then the indoor system, unit riser and horizontal trunk are compared and selected . After comparing the characteristics of different radiators, one is chose and layout according to the principle of layout, and to calculate the number of radiator. Perform hydraulic calculations to determine flow, pipe diameter, loop resistance, and unbalance ratio. Explain the advantages of building heat exchange station. According to the district heat load calculation to select the heat exchanger; according to the calculation of flow and head to select the circulating pump and make up the water pump; to select the water treatment equipment according to the flow; to select the decontamination equipment according to the diameter. According to the ratio of the proportion of each building to the area of Building 9, the heat load of each building is estimated. So The flow pipe diameter of each pipe segment is determined. In accordance the principle of maximum span to layout of the fixed bearing, and using the sleeve compensator for compensation of pipe. Between the fixed bearings, the guide bearing is arranged according to the maximum span of the movable bearing, and the horizontal thrust of each fixed bearing is calculated,which is in reasonable context.
