温和地区焓差控制对室内热舒适性和节能的影响
Effect of enthalpy difference control on indoor thermal comfort and energy saving in mild regions
摘要
Abstract
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 PMV 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 PPD in the registration hall is reduced by 11.92％,7.89％,5.91％,1.42％,1.47％,26.04％,while PPD in wards is reduced by 2.35％,16.7％,3.90％,0.18％,8.86％and 2.17％,respectively.关键词
