1、 基于污水热利用的供需侧负荷动态匹配研究 重庆大学硕士学位论文 （学术学位） 学生姓名：于祥雷 指导教师：张华玲 副教授 专 业：供热、供燃气、通风及空调工程 学科门类：工学 重庆大学城市建设与环境工程学院 二 O 一四年五月 The Research of Dynamically Matching the Load of Supply And Demand Side Based on the Sewage Heat Utilization A Thesis Submitted to Chongqing University in Partial Fulfillment of the Requ
2、irement for the Masters Degree of Engineering By Yu Xianglei Supervised by Prof.Zhang HuaLing Specialty: Heating, Gassing, Ventilation and Air-conditioning Engineering College of Urban Construction in the days that each country is promoting energy conservation and emissions reduction, urban sewage w
3、hich has low grade heating and cooling capacity has become a hot spot in the area of construction application of renewable resources. How to implement the more construction application of urban sewage heat and cold resources has become one of the current issue research and application of sewage-sour
4、ce heat pump project. The traditional sewage-source heat pump technology is mainly based on static using of sewage cooling and heating capacity, when the maximum sewage flow dont meet the requirements of the designing cold and hot load form building, people often deny the feasibility that wastewater
5、 is being as air conditioning heat and cold source, failed to make full use of urban sewage resources. This paper from the dynamicanalysis point of view, based on the rule that cold and heat resources from urban sewage is changed by the time, combined with dynamic characteristics that construction d
6、emand for cooling and heating capacity, analysis the contradictions between the demand of the building and the supply of urban sewage in time and quantity, explore how to more fully and better utilize the heat and cold resources of urban sewage in a dynamic way. In this paper, the results of the stu
7、dy for promoting the development and utilization of the heat and cold resources from urban sewage in a larger scope have a certain guiding significance. This paper has carried out three aspects of research work. First of all, the paper analyzes the dynamic relationship between the available cold and
8、 heat capacity from urban sewage and building cold and hot load, reveals the contradictions between urban sewage and building cold and hot load both in time and the number. From the dynamic characteristics that building load demand for cold and heat capacity, in the case of hotel buildings and shopp
9、ing malls, analyzed various parameters that influencing the changes of building load, through the Dset simulation software to simulate the dynamic load of two kinds of architectural in design day and month by month; Research every months air conditioning energy consumption of 7 hotels in Chongqing,
10、verify the load fluctuation features of hotel building from month to month。 Secondly, this article make a analyze and put forward matching methods based on three relations of sewage cooling and heating capacity and construction load in time and 重庆大学硕士学位论文 IV the number. When the sewage flow is great

13、 the initial investment and operating cost of sewage-source heat pump system ,and evaluate those three ways.When the sewage flow did not meet the requirements of the building in most of the time, the limit conditions are given for building application of composite sewage-source heat pump, energy sav
14、ing benefits of composite sewage-source heat pump system are analyzed relative to the conventional system under the condition. Finally, based on the two specific engineering as examples, make a detailed calculation and analysis using dynamic matching method proposed by paper for each project based o
15、n building cooling and heating load and sewage application conditions. And comparing various matching scheme, and concluded the optimal scheme of dynamic matching supply and demand side. The engineering case from the paper can provides the beneficial reference for the actual engineering application of sewage-source heat pump.
