采暖系统水力计算方法的适用性分析OACHSSCD

Hydraulic calculation is crucial for heating system design,as it is crucial to ensure that the heating system meets design requirements and operates with energy efficiency.The correct selection of friction coefficient has a direct impact on the final calculation result.In heating systems,the commonly used formula for calculating the friction resistance coefficient in turbulent areas is Colebrook's formula,but its function expression is an implicit function that requires iteration during calculation,making it inconvenient to use in engineering design.Liu Dezhong's formula is an explicit function expression,which is more convenient to calculate and obtain.This paper uses Liu Dezhong's formula to calculate the friction resistance of hot water heating systems,verifying the applicability of Liu Dezhong's formula in calculating the friction resistance of hot water heating systems,thereby ensuring the scientific design of heating systems and achieving energy-saving operation.
