结合人员行为的分散式空调系统能耗模拟

Research on Energy Consumption Simulation of Distributed Air Conditioning System Integrated with Occupant Behavior

随着模拟技术的发展和进步,新的应用场景对能耗模拟软件在更短时间内的模拟精度和准确度提出了挑战。分体式空调被大量安装于我国各类建筑当中,对其用能及运行情况进行准确刻画具有十分重要的意义。由于人行为对建筑能耗具有显著影响,并且对于采用分散式空调的建筑,人行为的随机影响更加明显,因此,在分散式空调的模拟当中加入人行为模型变得非常必要。本文针对现有一款主流能耗模拟软件EnergyPlus中对分散式空调系统模拟的缺陷以及并未考虑人员影响因素的问题,从人行为和软件自身空调模块出发,对分体机模块进行改进,并在模拟中加入人行为因素。结果表明改进后的分体机模型能够正确反映出其运行特性及室温波动特点;同时,结合了人行为的改进后分散式空调模型模拟结果与未考虑人行为影响的原有模型模拟结果存在明显差异。

Energy consumption simulation software is confronted with increasing challenges in accuracy and precision with the emerging applications. Split-type air conditioners are widely used in Chinese buildings. Thus, it＇s of great importance to simulate this kind of air conditioners in a more detailed and accurate way. Occupant behavior has been recognized as a significant factor that influences the energy consumption of buildings. In a building that is equipped with distributed air conditioning system, the stochastic impacts of occupants are especially salient. Therefore, it＇s quite necessary to integrate occupant behavior with the simulation of distributed air conditioning system. Specific to the problem that a prevailing simulation program-EnergyPlus, has some blemish in its distributed air conditioner module and lacks consideration of occupant behavior, this research aims to improve the module and add the occupant behavior model in simulation. Results show that the improved model can demonstrate the on-off operation and the temperature fluctuation correctly. Meanwhile, a simulation is conducted in this thesis on a hotel building integrating the occupant behavior model with the modified split-type air conditioner model, results of which suggest that it is necessary to add occupant behavior model in simulation.
