【摘要】：中央空调的能耗研究是当今社会空调行业中的热门课题,是国家可持续发展战略中的必备环节,越来越受到国家与社会的广泛关注。本文基于奶粉厂中央空调系统实际运行情况的分析研究,从工程实践中找出设计方案中的不足及可优化的节能措施,为以后食品行业的中央空调设计提供了参考。论文首先整体介绍了中央空调系统的设计情况,通过对系统中主要耗电设备的用电情况进行分析,找出系统中具有节能潜力的关键点;然后对空调主机的耗电量、蒸发温度、冷凝温度等数据进行统计分析,并结合空调主机负荷率、COP值的分布情况,验证空调主机设计选型是否合理;接着是对水泵耗电量运行数据的收集,并对水系统输送能效比进行计算分析,发现水泵变频技术在中央空调系统运用中节能效果显著;最后分析各类末端空调设备的能耗情况,并以JK1-1空调系统为例,重点阐述转轮净化空调机组在奶粉生产车间中的运用,从生产运行的工作制度出发寻找最经济运行模式。论文通过对中央空调系统的运行情况进行分析,发现本工程的空调设计冷负荷取值偏大,在全年运行过程中,空调主机绝大部分时间均处于部分负荷运行状态;在空调水系统设计中对冷却水的处理未能达到令人满意的效果;空调末端设备能耗偏大,存在冷热抵消,换热不均,直接排风等能量浪费情况。通过对本工程中央空调系统设计的不足和可取之处进行总结,为以后空调的节能改造和设计积累参考经验。
[Abstract]:The research on energy consumption of central air conditioning is a hot topic in the air conditioning industry nowadays. It is an essential link in the national sustainable development strategy and has been paid more and more attention by the country and society. Based on the analysis and study of the actual operation of the central air conditioning system in the milk powder factory, this paper finds out the deficiency of the design scheme and the energy saving measures which can be optimized from the engineering practice, which provides a reference for the future central air conditioning design of the food industry. Firstly, the paper introduces the design of central air conditioning system as a whole, finds out the key points with energy saving potential by analyzing the power consumption of the main power consuming equipment in the system, and then the power consumption and evaporation temperature of the main engine of the air conditioning system. According to the data of condensing temperature and the distribution of load rate and cop value, it is verified whether the design and selection of air conditioning mainframe is reasonable or not, and then the collection of the running data of water pump power consumption is carried out. The energy efficiency ratio of water system transportation is calculated and analyzed, and it is found that the pump frequency conversion technology has remarkable energy saving effect in the application of central air conditioning system. Finally, the energy consumption of all kinds of terminal air conditioning equipment is analyzed, and the JK1-1 air conditioning system is taken as an example. The application of rotary wheel purifying air conditioning unit in milk powder production workshop is expounded, and the most economical operation mode is found out from the working system of production and operation. Through the analysis of the operation of the central air-conditioning system, it is found that the design cooling load of this project is on the high side. During the whole year, the main engine of the air conditioner is in part load running state for most of the time. In the design of air conditioning water system, the treatment of cooling water is not satisfactory, and the energy consumption of the air conditioning terminal equipment is too large, the heat and cold is offset, the heat exchange is uneven, and the energy is wasted directly. By summing up the shortcomings and merits of the design of the central air-conditioning system of this project, the paper accumulates the reference experience for the future energy saving transformation and design of the air conditioning system.
