多种固体蓄热装置放热特性的数值模拟研究

Numerical Simulation Study on Heat Dissipation Characteristics of Multiple Solid Regenerative Devices

为缓解国家电网压力,根据国家民用建筑供暖标准,设计了3种不同结构的固体蓄热装置。用数值模拟的方法研究了不同结构对蓄热装置放热特性的影响。结果表明,在蓄热体总体积一定的情况下,2块长方体蓄热体所在的正方体框内的空气温度最高,其次是2块球形蓄热体所在的正方体,而1块球形蓄热体所在的正方体框内的空气温度最低。

In order to reduce the pressure of national state power grid,responding to the offpeak electricity utilization policy,solid regenerative devices with three different kinds of structures are designed according to the national civil building heating standard.The influence of different kinds of structures on the heat dissipation characteristics of the solid regenerative device is studied by the method of numerical simulation.The results show that when the total volume of heat accumulators is constant,the air temperature in the cube with two cubic heat accumulators is the highest,followed by two spherical heat accumulators.The air temperature in the cube with one spherical heat accumulator is the lowest.
