摘要
【目的】旨在对空调负荷参与虚拟电厂调控中用户降负荷后对室内热湿环境影响问题进行分析。【方法】以广州地区某公共建筑为研究对象,采用TRNSYS软件搭建空调系统模型,开发功率受限冷水机组模块,模拟不同负荷率、不同冷水机组输入功率下室内温度变化情况。【结果】结果显示:在100%负荷率下调节冷水机组输入功率为70%、63%、57%、50%、45%;80%负荷率下调节冷水机组输入功率为60%、56%、50%、45%、37%;60%负荷率下调节冷水机组输入功率为50%、44%、38%、25%、22%;40%负荷率下冷水机组调节输入功率为25%、23%、20%、16%、13%时,室内温度比设计温度分别提高了1℃、1.5℃、2℃、2.5℃、3℃。【结论】逐步降低冷水机组输入功率时,室内温度出现不同程度的上升。研究结果可为合理调节空调系统以实现电力负荷聚合交易目标提供借鉴。
[Purposes]This study aims to analyze the impact of air conditioning load reduction on indoor thermal and humidity environments when participating in virtual power plant regulation.[Methods]A public building in Guangzhou was selected as the research object.The TRNSYS software was used to build an air conditioning system model,and a power-limited chiller module was developed to simulate indoor temperature changes under different load rates and varying chiller input power levels.[Findings]The results show that when chiller input power was adjusted to 70%,63%,57%,50%,and 45%at 100%load rate;60%,56%,50%,45%,and 37%at 80%load rate;50%,44%,38%,25%,and 22%at 60%load rate;and 25%,23%,20%,16%,and 13%at 40%load rate,the indoor temperature increased by 1℃,1.5℃,2℃,2.5℃,and 3℃respectively compared to the design temperature.[Conclusions]Gradually reducing the chiller input power leads to varying degrees of indoor temperature rise.The re⁃search results can provide reference for reasonable air conditioning system adjustment to achieve power load aggregation trading objectives.
