摘　　要：随着当前社会的发展,人们对于舒适环境的需求逐渐提高,空调系统能耗占比较之前逐步增大。在“双碳”背景下,降低公共建筑能耗和提高室内舒适度的方法尤为重要。基于变风量焓差控制,以某医院为研究对象,对变新风系统的室内舒适度P MV和建筑总能耗展开分析。采用K-means聚类方法区分出6种典型日,进行模拟仿真。结果表明:相比传统的控制方法,变新风焓差控制策略能够明显降低建筑空调能耗8.69%、5.92%、14.05%、5.65%、6.10%、5.33%,同时在6种典型日下,挂号大厅的人员不满意率P_(PD)分别降低了11.92%、7.89%、5.91%、1.42%、1.47%、26.04%,病房的P_(PD)降低了2.35%、16.7%、3.90%、0.18%、8.86%、2.17%。With the development of current society,people's demand for a comfortable environment is gradually increasing,and the energy consumption of air-conditioning systems is gradually increasing compared with the previous.Under the background of“double carbon”,the method of reducing energy consumption and improving indoor comfort in public buildings is particularly important.Based on the enthalpy difference control of variable air volume,the indoor comfort P MV and total energy consumption of a hospital were analyzed by a variable fresh air system.The K-means clustering method was used to distinguish six typical days and simulations were performed.The results show that compared with the traditional control method,the variable fresh air enthalpy difference control strategy can significantly reduce the building air-conditioning energy consumption by 8.69%,5.92%,14.05%,5.65%,6.10%,5.33%.At the same time,in the six typical days,the personnel dissatisfaction P_(PD)in the registration hall is reduced by 11.92%,7.89%,5.91%,1.42%,1.47%,26.04%,while P_(PD)in wards is reduced by 2.35%,16.7%,3.90%,0.18%,8.86%and 2.17%,respectively.
