目的：现代医疗建筑中央空调系统运行状况缺少有效便捷的评估方法。文中提出了基于物联网应用，依据室外环境温度和空调末端用户的室内温度数据，分析并完善医院中央空调系统运行状况评价方法。方法以中央空调物联网获取室外温度和各末端用户室内温度的历史数据，在给定的时间窗口内，以室外温度历史数据的方差和各末端室内温度历史数据方差，建立相关性及方差比的数学指标，并从理论上导出用该指标评价空调系统运行状态的正确性和可靠性。通过南京军区南京总医院中央空调系统所采集的数据进行分析验证。结果2个时间段室内外温度的相关系数均随时间呈现一定的波动，但总体上空调运行期间相关系数的平均值为0．305，显著低于空调停运期间的平均值0．585。结论利用室内温度与各末端用户室内温度参数的降低幅度可表征空调系统运行质量的高低。该参数可用于大型医疗建筑中央空调系统运行状态的评价。

Objective A correlation method for evaluating operation quality of air conditioning systems is proposed , based on the outdoor and the indoor temperature history data of the terminal user from internet of things for the central air conditioning system , for lacking efficient way to evaluate . Methods A methematical model is set up based on the variance ratio of the data of the indoor and out temperture obtained from IOT within a given time interval , and theoretically induce the possibility and correctness to employ these index to evaluate the operation quality of the central air conditioning system . Results A typical central air conditioning system of a large sacal hospital is analyzed , the results shows the variance ratio of the indoor and outdoor temperature can reflect the capacity of the central air conditioning system for controlling the indoor temperature . Conclusion The method proposed for evaluating the op-eration quality of the air conditioning system based on IOT system is theotically correct and practically efficient , and can be employed to evaluate the operation quality of the air conditioning system of large scale medical buildings .
