冬季空调间歇运行室内温度特性及节能潜力的理论与实验研究

本文通过对冬季空调房间空调开关机过程试验得到的室内环境温度数据进行分析,建立了温度变化的理论模型,分析结果表明,房间内气温随时间呈指数规律变化,且时间越长,室内温度越趋于稳定。通过对开关机过程中室内PMV值进行计算,在对人体热舒适影响不大的条件下,得到了试验房间空调间歇运行较佳的启停时间组合方式,与常规连续运行方式相比节能潜力最高可达40%。

Temperature characteristics in room in winter and theoretical and experimental research of potential energy saving by air conditioning intermittent operation

By air conditioning start-stop testing in room in winter,the temperature data in room analysis that temperature changes during the theoretical model.the results showes that the temperature with time exponential changing,and time longer,the temperature more stable.PMV values calculated on the air conditioning start-stop process,in little impact on thermal comfort,have been testing the better time of interval combination by air-conditioning intermittent operation,energy saving up to 40% compared with the conventional continuous operation.
