In the green energy saving and energy saving, the humanity and the intelligent fort living environment is being the new direction of the HVAC development. Of course, the lower base determines the superstructure, the higher level should start from the basic content. Centralized heating system has the advantages of large heat capacity, high heat efficiency, saving labor force and covers an area of small, etc. pared with the previous decentralized heating system, bee the current rapid development of domestic urban heating mode, is recognized as the central heating system is heating heating , customers, and is posed of three parts. The design of the central heating and hot water work design for a normal university in Taiyuan. So the design content is started by the three parts. Heat source: the first grade is the municipal water supply。 the two level work for directly buried installation. Hot user: for school classrooms, dormitories, offices, laboratories, etc., and for the middle and lower buildings. At present, the energy shortage will be the important factor that restrict the economic development of our country, and has been recognized as the universal problem of the whole world. Heating engineering design should start from the point of view to determine the broaden sources of ine and reduce expenditure, the prehensive utilization scheme of suit one39。 ................................................................. 24 水泵與管網(wǎng)聯(lián)合特性曲線 ......................................................................... 25 水力工況的穩(wěn)定性 ................................................................................................ 26 本章小結(jié) ................................................................................................................ 26 第 6 章 運行調(diào)節(jié) ............................................................................................................ 27 運行調(diào)節(jié)形式 ........................................................................................................ 27 運行調(diào)節(jié)原理 ........................................................................................................ 27 運行調(diào)節(jié)實例 ........................................................................................................ 29 本章小結(jié) ........................................................................
