【 摘 要 】

In the energy efficiency analysis of cooling water system, the fuzzy comprehensive evaluation method is used to establish the energy efficiency analysis factor system. Firstly, it divides the factors into different levels, quantifies the evaluation indexes of factor sets, establishes the weights of each factor and the membership function by using the analytic hierarchy process (AHP), and constructs a complete fuzzy evaluation system. Then through the description and calculation of a specific example, combined with fuzzy theory, the energy efficiency state of the whole cooling water system and each link is obtained. The feasibility and rationality of the application of fuzzy comprehensive evaluation method to the energy efficiency evaluation of cooling water system are explained by analysis, which provides a new way to solve the problem of energy efficiency evaluation of cooling water system.
