Analysis of influencing factors on indoor thermal-humid environment for radiant cooling and wall attachment jet air conditioning system
摘要
Abstract
Against the backdrop of the global energy crisis and the pressing demand for building energy efficiency,radiant air-conditioning technology has drawn widespread attention for its advantages in energy savings and thermal comfort.To figure out how three panel positions affect room heat transfer under varying water-supply parameters,an experimental platform integrating a radiant chilled-water loop and an attached-jet ventilation system was established.Temperature,humidity and air velocity were measured,and the indoor environmental fields were further analyzed with CFD simulations.The results show that the ceiling-mounted layout delivers the best temperature uniformity:the vertical temperature difference is reduced by about 46%compared with the single-side wall layout,and the non-uniformity coefficient of air velocity in the occupied zone is only 0.12,markedly enhancing thermal comfort.Raising the supply-water temperature by 2℃increases the average temperature on every measured plane by approximately 1.4℃,whereas increasing the flow rate from 0.33 m3/h to 0.75 m3/h lowers the average temperature by merely 1℃;therefore,supply-water temperature should be prioritized in actual operation.All these three layouts can maintain indoor humidity within the range of 40%-60%comfort band,with the ceiling layout providing the most uniform moisture distribution.关键词
