【摘要】 利用相变传热理论,建立起分析热盘管置于封装相变储能材料层中的储能采暖地板热性能的理论模型,采用焓分析法,数值模拟贮热介质在曲边边界条件下、不同的热边界条件的作用,探索蓄能地板在不同的管间距布置、不同的地板覆盖层和不同供热工况等各种因素对储能地板热性能及蓄热效果的影响规律。更多还原

【Abstract】 By the theory of phase change heat transfer,the energy storage model of radiant floor heating with a kind of enclosed phase change material(PCM) is set up.With the method of enthalpy,the actions under different heat boundary conditions and the curve boundary conditions are simulated numerically,influence rules on thermal characteristics of energy storage floor and storage heat effect under different pipe distance layout,different floor covers and different supply heat conditions are discussed更多还原
