【摘要】：大型超市在当今城市是不可缺少的一个建筑业态,尤其是在城镇发展飞速的中国,绝大多数在城市中生活和工作的人们把大型超市选为购物的首选之地,所以,大型超市室内的环境品质变得愈发重要。这样一来,商家和消费者对大型超市的中央空调系统的重视程度也变得越来越高。这就使得我们对大型超市的中央空调系统的节能运行管理要做到:不仅要优化设备运行效率,提高电能利用效率,同时还要提高室内环境品质,满足人体热舒适条件,为顾客提供一个满意的购物环境和适宜的购物体验。本文通过对长沙某大型地下超市主要用能设备及中央空调系统运行情况的研究,从中央空调运行管理层面上提出更加适合该超市特点的动态运行方式,使得该超市的空调系统在满足购物人员对室内空气品质要求的同时,降低能耗和运行费用。首先在现在已有的研究成果的基础上,从超市购物的顾客的需求入手,确定该大型超市调研的主要内容,包括:温度、湿度、二氧化碳浓度、噪声等。同时根据购物者在超市内满意度的调查和相关规范标准,对当前室内环境状况经行评价。其次,通过阅读相关文献和实地调研,了解到该大型超市主要能耗设备为:中央空调设备、冷冻冷藏设备以及照明设备等。根据调研结果,本文旨在分析各用能设备的配比与管理运行之间的能耗关系。再次,对超市的客流量的变化和不同卖场区域的客流密度进行统计分析,建立该超市客流量变化的预测模型。在对该超市室外温度监测的基础之上,对比该超市用能设备运行情况和超市客流量变化情况并进行分析研究,得出该超市顾客行为特征是超市空调系统及其他设备能耗的主要影响因素,从而建立起该超市顾客行为特征及客流量与空调系统及其他设备能耗之间的关联模型。最后,基于该超市卖场环境的变化和绝大多数购物者的需求,调整该超市空调系统的运行模式、运行时间、运行参数,在提高设备利用效率的同时降低能耗、削减运行费用,实现超市中央空调系统的节能运行优化管理。本研究通过整合该超市现有中央空调系统的运行管理策略,在调研的基础上提出空调系统优化运行策略,使该超市空调系统运行更高效,环境更优美。为全面推进地区超市空调节能运行起到一定借鉴作用,并相应国家节能减排政策实现能源高效利用。
[Abstract]:Large supermarkets are an indispensable architectural form in today's cities, especially in China, where the cities and towns are developing rapidly. Most people living and working in cities choose supermarkets as the first choice for shopping, so, The indoor environmental quality of large supermarkets is becoming more and more important. As a result, businesses and consumers are paying more and more attention to the central air-conditioning systems of large supermarkets. This makes it necessary for us to manage the energy saving operation of the central air conditioning system in large supermarkets: not only to optimize the operation efficiency of the equipment and to improve the efficiency of electricity utilization, but also to improve the quality of the indoor environment to meet the thermal comfort conditions of the human body. To provide customers with a satisfactory shopping environment and a suitable shopping experience. Based on the study of main energy using equipment and central air conditioning system in a large underground supermarket in Changsha, this paper puts forward a dynamic operation mode which is more suitable for the characteristics of this supermarket from the operation management level of central air conditioning. The air conditioning system of the supermarket not only meets the requirements of indoor air quality, but also reduces the energy consumption and operation cost. Firstly, based on the existing research results, the main contents of the research in the supermarket are determined, including temperature, humidity, carbon dioxide concentration, noise and so on. At the same time, according to the survey of shoppers' satisfaction in the supermarket and relevant standard standards, the current indoor environment condition is evaluated. Secondly, through reading relevant literature and field investigation, we know that the main energy consumption equipment of this supermarket is: central air conditioning equipment, refrigerated refrigeration equipment and lighting equipment. According to the research results, this paper aims to analyze the energy consumption relationship between the ratio of each energy-using equipment and the management operation. Thirdly, the change of the supermarket's passenger flow and the passenger flow density in different selling areas are analyzed statistically, and the prediction model of the supermarket's passenger flow is established. On the basis of monitoring the outdoor temperature of the supermarket, this paper compares the operation situation of the energy-using equipment and the change of the supermarket passenger flow, and makes an analysis and research. It is concluded that the characteristics of customer behavior are the main factors affecting the energy consumption of the air-conditioning system and other equipment in the supermarket, and the correlation model between the characteristics of customer behavior and the passenger flow of the supermarket and the energy consumption of the air-conditioning system and other equipment is established. Finally, based on the changes of the supermarket store environment and the needs of the majority of shoppers, the operation mode, operation time, operation parameters of the air conditioning system in the supermarket are adjusted to improve the utilization efficiency of the equipment and to reduce the energy consumption and operation cost. Realize the optimization management of energy saving operation of supermarket central air conditioning system. By integrating the operation and management strategies of the existing central air-conditioning system in the supermarket, this study puts forward the optimal operation strategy of the air-conditioning system on the basis of investigation and research, in order to make the supermarket air conditioning system run more efficiently and in a more beautiful environment. In order to promote the local supermarket air conditioning energy-saving operation plays a certain reference role, and the corresponding national energy conservation and emission reduction policies to achieve energy efficient use.
