低温送风在空气调节系统的节能和提高体感舒适度上有着独特的优势。但同时,送风温度偏低也带来了冷风下坠、温度场不均匀、热舒适性下降的隐患。本文针对低温送风中存在的这些问题,首先确立了低温送风的气流组织评价标准,并设计了包含制冷系统、冰蓄冷系统和测量系统在内的一整套低温送风实验系统,最后对不同的送风温度下实验结果进行定性和定量的分析,从而得到了相应的解决方法和结论。
Low temperature air supply in the air conditioning system, energy saving and improve the sense of comfort has a unique advantage. However, at the same time, the low supply air temperature also brings about the risk of cold wind falling, uneven temperature field and decreasing thermal comfort. In order to solve the problems existing in low temperature air supply, this paper first establishes the evaluation standard of air flow for low temperature air supply and designs a set of low temperature air supply experimental system including refrigeration system, ice storage system and measurement system. Finally, The experimental results of the supply air temperature qualitative and quantitative analysis, resulting in the corresponding solutions and conclusions.
