Study on Prediction Model of Refrigeration Performance Curve of Open Radiant Ceiling

本文以开式辐射吊顶为主要研究对象,对其制冷量的预测方法进行深入研究。通过经实验验证的模型对开式辐射吊顶在各个影响因子水平下的制冷量进行模拟并收集模拟数据作为回归资料。以ASHRAE标准中闭式辐射吊顶的制冷量性能曲线其为基础并对曲线中的系数C和指数n加以修正作为开式辐射吊顶的制冷量性能预测曲线。利用SPSS软件对回归资料进行整理分析,最终得到可以广泛应用于工程中的开式辐射吊顶制冷量性能曲线预测模型。

This article focuses on the open radiation ceiling as the main research object,and conducts in-depth research on the prediction method of its cooling capacity.Simulate the cooling capacity of an open radiation ceiling at various influencing factor levels using an experimentally validated model and collect simulation data as regression data.Based on the cooling capacity performance curve of the ASHRAE standard for closed radiation ceilings,the coefficient C and index n in the curve are corrected as the cooling capacity performance prediction curve for open radiation ceilings.By using SPSS software to organize and analyze the regression data,a performance curve prediction model for the cooling capacity of open radiation ceiling can be widely applied in engineering.
