The evaluation system of three levels and six different attributes was constructed and the optimization model based on AHP and VIKOR was established. Meanwhile, the evaluation method and steps were pointed out. Based on this, by the use of established model, ten kinds of low-temperature phase change materials were sorted according to their comprehensive performance. The results show that the established evaluation system and model based on AHP and VIKOR is effective and practical for selecting optimal PCMs. Sodiumacetate trihydrate and stearic acid are found to be the optimal inorganic and organic p
