【摘要】：常规建筑能源审计主要关注的是建筑全年总能耗数据的收集,通常是分析能源账单,从总体上了解建筑的用能情况,对总能耗进行简单评价。目前绝大多数的建筑没有分项计量,无法通过常规的能源审计了解空调系统运行及能效情况,不能满足空调系统节能改造的需求。本文结合武汉市以节能改造为目的的医院建筑能源审计项目对医疗建筑空调系统能耗专项审计进行以下几方面的研究:在能耗调查数据基础上,通过与国内不同地区医院建筑能耗对比,分析武汉市部分医院的用能现状;对医院主要建筑概况及空调系统概况进行整理与分析,并结合能耗数据,分析其能耗特征及能源消耗构成。从空调系统能耗专项审计的能耗拆分角度,以武汉市某典型医院建筑为例,应用能耗季节拆分法、当量满负荷运行小时数法及能耗模拟法对该医院的空调、采暖及生活热水能耗进行拆分,探讨不同拆分方法在医疗建筑空调系统能耗专项审计中的适用性,提出能耗模拟法更适合能耗专项审计的能耗拆分。针对能耗模拟法输入参数的不确定性对能耗拆分结果的影响,在典型医院能耗模型上采用单因素与正交试验定量分别分析能耗模型中各不确定参数对能耗拆分的影响,确定影响能耗拆分结果的主要输入参数。参考不确定性分析结果,确定空调系统能耗专项审计测试的方向与重点。分析典型医院直燃机组及锅炉的测试数据,对能耗模型进行参数修正,探讨空调机组重点测试与分析的意义。
[Abstract]:The general energy audit of buildings is mainly concerned with the collection of annual energy consumption data, usually the analysis of energy bills, the overall understanding of the energy use of buildings, and a simple evaluation of the total energy consumption. At present, most buildings do not have itemized metering, can not understand the operation and energy efficiency of air conditioning system through conventional energy audit, and can not meet the need of energy saving transformation of air conditioning system. Combined with the energy audit project of hospital building in Wuhan, this paper studies the energy consumption audit of air conditioning system of medical buildings in the following aspects: on the basis of energy consumption survey data, By comparing the energy consumption of hospitals in different regions of China, this paper analyzes the present situation of energy consumption in some hospitals in Wuhan. The general situation of hospital building and air conditioning system is analyzed and the characteristics of energy consumption and the composition of energy consumption are analyzed based on the data of energy consumption. Taking a typical hospital building in Wuhan as an example, the energy consumption split method, equivalent full load running hours method and energy consumption simulation method are applied to air conditioning in a typical hospital building in Wuhan from the angle of energy consumption split by special audit of air conditioning system energy consumption. The energy consumption of heating and domestic hot water is split, and the applicability of different separation methods in the special audit of energy consumption of air conditioning system in medical buildings is discussed, and the energy consumption simulation method is proposed to be more suitable for the separation of energy consumption in special audit of energy consumption. In view of the effect of uncertainty of input parameters of energy consumption simulation method on the results of energy separation, single factor and orthogonal test were used to quantitatively analyze the effects of uncertain parameters on energy separation in typical hospital energy consumption models. The main input parameters that affect the result of energy splitting are determined. Referring to the uncertainty analysis results, the direction and key points of the special audit test of air conditioning system energy consumption are determined. This paper analyzes the test data of typical hospital direct-fired units and boilers, modifies the energy consumption model, and discusses the significance of key test and analysis of air-conditioning units.
