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，大大提高工程设计与运行的经济性和科学性
Steam accumulators are energy-saving devices that are widely used in heating systems. The size of the necessary heat storage directly affects the volume of the accumulator, which in turn affects the investment and economy of the entire heating system. The use of Fourier series calculation of the necessary heat storage than the traditional calculation method is more reasonable and greatly enhance the engineering design and operation of the economy and scientific
