运用傅立叶级数计算蒸汽蓄热器的必需蓄热量

Using Fourier Series to Compute the Needed Capacity of Steam Accumulator

蒸汽蓄热器是广泛应用于供热系统中的节能设备。其中必需蓄热量的大小直接影响蓄热器的容积，进而影响整个供热系统的投资和经济性。运用傅立叶级数计算的必需蓄热量比传统的计算方法更加合理。

Steam accumulator is an energy saving equipment widely used in heat supply system.Its needed capacity affects its volume,and then the investment of the whole system.The computed capacity by Fourier series in this paper is more reasonable than by traditional methods.It makes engineering design and system running more economical and scientific.
