西安某商场空调系统能耗模拟与节能研究

Simulation and Study on Energy-saving of Air-conditioning System Energy Consumption of a Shopping Plaza in XI'an

本文采用了调研、测试和EnergyPlus软件模拟相结合的分析方法,对西安市某大型商场空调系统能耗作了研究分析。通过测试对室内外温度以及制冷机冷冻水、冷却水温度进行了分析,发现商场中各楼层存在着温度分布不均匀现象。随着楼层升高,每层的室内温度也升高。同时对机组测试中还发现,冷机处于部分负荷状态下运行,制冷机低效运行。最后通过模拟结果提出了几项节能措施并对其节能效果进行分析。

The method of research, testing, and software simulation analysis by using EnergyPlus was used to study energy consumption of the air conditioning system of a large shopping plaza in XI＇ an in this paper. Indoor and outdoor temperature and the refrigerator of chilled water, cooling water temperature were analyzed. It is found that there is a phenomenon about uneven temperature distribution on each floor in the shopping plaza. With the increase height of floors, each floor indoor temperatures to rise. At the same time it is found that chiller is running under partial load conditions, refrigerator less efficient to run in the test. Finally a number of energy-saving measures were adopted by the simulation results and analyzed its energy-saving effect.
