基于昆明基准大气压力高海拔燃具热负荷计算

Heat Load Calculation of High Altitude Gas Appliances Based on Kunming Reference Atmospheric Pressure

基于K-means聚类算法,确定昆明基准大气压力为81.1 kPa。提出昆明实测热负荷和昆明实测折算热负荷的计算公式。昆明实测热负荷与实测热负荷计算结果相同,昆明实测折算热负荷比实测折算热负荷低10%左右。昆明实测折算热负荷与昆明实测热负荷比较接近,两者偏差为4%~7%,实测折算热负荷与实测热负荷偏差为16%~19%。在燃具铭牌上标注标称额定负荷、昆明额定热负荷,表明燃具在不同使用环境的额定热负荷,以利于用户准确选择燃具。

Based on the K-means clustering algorithm,the reference atmospheric pressure in Kunming is determined to be 81.1 kPa.The calculation formulas of the measured heat load in Kunming and the measured converted heat load in Kunming are proposed.The measured heat load in Kunming is the same as the calculated result of the measured heat load,and the measured converted heat load in Kunming is about 10%lower than the measured converted heat load.The measured converted heat load in Kunming is close to the measured heat load in Kunming,the deviation between the both is 4%?7%,and the deviation between the measured converted heat load and the measured heat load is 16%?19%.The nominal rated heat load and Kunming rated heat load shall be marked on the gas appliance nameplate to indicate the rated heat load of the gas appliances in different service environments,so as to facilitate users to accurately select gas appliances.
