利用频域有限元法分析内嵌管式辐射地板频域热特性
Analysis on frequency thermal characteristics of pipe-embedded radiant floor based on frequency-domain finite element method
摘要
Abstract
Analyzing the frequency thermal characteristics of the pipe-embedded radiant floor may give a further insight into its dynamic thermal performance and important guidelines for the system and control design.A frequency-domain finite element model of the pipe-embedded radiant floor is developed.The time-domain model of this structure is also developed by using ANSYS (ANAYS model)for reference.The accuracy of the frequency-domain finite element model of this structure is evaluated by comparing its results with that of the ANSYS model.The frequency thermal characteristics of the pipe-embedded radiant floor are calculated and analyzed by using this frequency-domain finite element model.The frequency thermal responses of the pipe-embedded radiant floor are basically unchanged with the frequency in low-frequency range while change rapidly in high-frequency range.Therefore dynamic calculation method should be adopted in predicting the heat transfer of the pipe-embedded radiant floor especially when high-frequency thermal disturbances are dominant in the room.关键词
