住宅樓分户采暖与热力站热力管网设计毕业设计说明书.docVIP

太原世纪花园住宅楼分户采暖与热力站、热力管网设计 摘 要 采暖就是用人工的方法向室内供给热量，使保持一定的室内温度，以满足人们对室内条件和工作条件的要求。所有供暖系统都由热媒制备（热源）、热媒输送和热媒利用（散热设备）三个主要部分组成。 本设计主要采用分区供热和分户计量采暖系统，热源由换热站集中供给，散热器给室内的供热方式由对流供热和辐射供热。根据此建筑物的特点采用分区供热，以防止压力过大而超过底层散热器设备的允许值。散热器采用上供下回的连接方式，管道敷设在垫层内，使室内布置更加合理、美观。采暖室内系统采用双管同程式，供热中干管系统采用双管异程式，对于异程式来说上层循环环路长度长阻力大，下层循环环路长度短阻力小，刚好抵消重力作用产生的上层大于下层的附加压力，减小垂直失调的问题。同时在各个用户的入口都有热计量表，用户就可以根据自己的需要来调节热量，这样既满足了人们对生活条件的需要，又符合了经济、节能等方面的要求。 关键词：热能工程；热媒；热源；分户采暖 The Design of Household-based Medium Heating, Heat Exchanger station and Heating-supply pipe network for Taiyuans Century Garden Abstract Heating is to use artificial methods to the indoor heat supply, maintaining a certain level of the indoor temperature to meet the peoples indoor and working conditions demands. All heating systems by the heat of the media (heat), heat-borne transmission and use of heat medium (cooling equipment) of three main components. The main design and use of district heating household metering heating system, heat from the ground floor of a heat transfer station on supply, the indoor heating radiator to form by convection heating and heat radiation. According to the characteristics of buildings used district heating, in order to prevent excessive pressure on the bottom radiator equipment and over the allowable value. The radiator is connected by the means of come the next time, the laying of pipelines in the cushion, the interior layout more rational, attractive. Indoor heating system uses the form of twin-tube in different process. The trunk system of Heating system uses the form of twin-tube in different process.??for the form of twin-tube in different proces, the length and the resistance of upper circulation is great and the length and the resistance of the lower cycle loop length is small and it just offsets the additional pressure and it can reduce the vertical disorders . At the same time in all users have the entrance of meters, users will be able according to their own needs to adjust the heat s
