【摘要】：随着人们生活水平的提高,人们对于生活环境的要求越来越高,空调是提高房间环境的一个很重要环节。目前生活中使用率最高的空调系统是风机盘管加新风系统和分体式空调系统。对于办公建筑来说,旧建筑一般使用的是分体式空调,而在新建的建筑中风机盘管加新风系统的使用率越来越高。本文所选建筑空调系统存在的主要问题是:不在规定的时间内,主机是不开的,即使有相当多的人需要制冷/制热环境时,也不能满足要求;在规定的时间内开启主机,如果有相当多的人不在,不需要制冷/制热环境,即使关闭了风机盘管,但是主机还是运行的。本文计算出了主机的能耗占整个空调系统能耗的70%左右,这就造成了很大的能源浪费。本文主要目的是平衡能源投入和工作环境之间的关系。风机盘管系统和分体式系统都有自己的优缺点,本文以某高校的一栋办公实验建筑为例,从初投资、运行能耗模拟和计算、运行管理费用、折旧费用、投资利息等方面对于两种空调系统进行了经济上的量化分析。论文得到的主要结论有:(1)分体式空调器的输入功率的主要影响因素有室外温度、室内温度、空调的设定温度等,从这几方面着手推导出空调器输入功率的理论解;(2)计算出所选建筑分别使用风机盘管系统和分体式系统的初投资差,得出风机盘管系统的初投资比分体式空调系统的初投资高得多的结论;(3)对于所选建筑使用分体式空调系统比使用风机盘管系统的运行能耗高一点点;(4)由于风机盘管系统和分体式空调系统的使用寿命周期不同,虽然风机盘管系统比分体式系统的初投资和运行费用总和高,但是由于寿命不同,最终每年的费用两者相差不大;(5)分体式空调对于解决像高校这种老师和学生使用时间不太一致,而且使用时间不是很固定的建筑来说是很有效的,对于本课题所选的建筑这一类型,分体式空调可以很好的协调能耗和学习工作环境之间的关系,但是不同的建筑选择哪种空调系统形式,要根据地域、建筑面积、人员使用规律等多方面综合考虑。本文的研究成果对于办公建筑选择空调系统形式的运行能耗、初投资、舒适性等均有重要的意义。
[Abstract]:With the improvement of people's living standard, people's demand for living environment is higher and higher. Air conditioning is a very important part of improving the room environment. At present, the air conditioning system with the highest utilization rate in daily life is the fan coil unit plus fresh air system and the split air conditioning system. For office buildings, the old buildings generally use separate air conditioners. In the newly built building, the utilization rate of the fan coil unit plus fresh air system is increasing. The main problem of the air conditioning system in the building selected in this paper is that the main engine is not open within the specified time. Even when a considerable number of people are in need of a refrigeration / heating environment, they cannot meet the requirements; if the mainframe is opened within a specified time, if a considerable number of people are not present, no refrigeration / heating environment is required, even if the fan coil unit is closed, However, the main engine is still running. This paper calculates that the energy consumption of the main engine accounts for about 70% of the total energy consumption of the air conditioning system. The main purpose of this paper is to balance the relationship between energy input and working environment. Both the fan coil system and the split system have their own advantages and disadvantages. This paper takes an office experimental building in a university as an example. From the initial investment, operating energy consumption simulation and calculation, operating management costs, depreciation costs, The main conclusions of this paper are as follows: the main factors influencing the input power of the split air conditioner are outdoor temperature, indoor temperature, air conditioning setting temperature, etc. From these aspects, the theoretical solution of the input power of the air conditioner is deduced. (2) the initial investment difference of the selected building using the fan coil system and the split system is calculated respectively. It is concluded that the initial investment of the fan coil system is much higher than that of the split air conditioning system. (3) for the selected building, the energy consumption of the separate air conditioning system is a little bit higher than that of the fan coil system.) because of the fan disk, the energy consumption of the fan coil system is slightly higher than that of the fan coil system. The life cycle of the tube system is different from that of the split air conditioning system. Although the initial investment and operation cost of the fan-coil system is higher than that of the split system, but due to the difference in service life, The final cost per year is not much different (5) the split air conditioning is effective in solving buildings where teachers and students, such as colleges and universities, do not use the same amount of time and do not have a very fixed time to use. For the type of building selected in this paper, split air conditioning can well coordinate the relationship between energy consumption and learning working environment, but different buildings choose which air conditioning system form, according to the region, building area, The research results of this paper are of great significance for office buildings to choose the operation energy consumption, initial investment and comfort of air conditioning system.
