The pipe network design has a direct influence on operating energy consumption and investment costs in district cooling systems. In this paper, a method of optimal design for pipe network by integer programming is developed, focusing on using 0-1 variables to solve the problem of optimal path and diameter in pipe network. A mathematical model for pipe network planning and diameter optimization is constructed, which includes objective function and constraints. Taking a district cooling system for example, the methods of integer programming and economic friction factor are used respectively. The result of integer programming can make the annual cost save 8.6%, and also validate the feasibility and applicability of the method.
