Optimal design method of heating pipe diameter based on life cycle

Based on the modern optimal algorithm and the conventional pipe diameter selecting method, presents an optimal design method of pipe diameters. Using this method, firstly selects several feasible layout schemes based on the hydraulic calculation, then determines the optimal scheme, whose network cost in a life cycle is the lowest. The case study analysis shows that this method eliminates the trouble of programming, overcomes the blindness of the traditional method, and is more energy efficient and more convenient to use.
