货币存在着时间价值,在热油输送管道保温层厚度的设计计算中,为考虑货币时间价值对最优保温层厚度的影响,而将基准贴现率引入热油管道最优保温层厚度的计算公式中,导出了考虑货币时间价值动态最优保温层厚度的计算式。文中对应用公式选择最佳保温材料作了介绍,并将货币时间价值对热输管道最优保温层厚度的影响进行了相应的分析和讨论,指出在确定热油管道的最优保温层厚度时,一般应以“动态”公式作为计算的依据。
In the design and calculation of thermal insulation thickness of hot oil pipeline, in order to consider the influence of currency time value on the optimal thermal insulation layer thickness, the reference discount rate is introduced into the formula of the optimal thermal insulation layer thickness of thermal oil pipeline , The formula for calculating the optimal thermal insulation thickness considering the time value of money is derived. The paper chooses the best insulation material by applying the formula and introduces the influence of the time value of money on the optimal insulation thickness of the heat pipe. It is pointed out that in determining the optimum thickness of the thermal oil pipeline, , Generally should be “dynamic” formula as the basis for calculation.
