Fuzzy multi-level comprehensive evaluation of air conditioning cold source equipment

Air conditioning cold source equipment;  fuzzy comprehensive judgment;  Membership functions

Based on fuzzy mathematics, the comprehensive performance and economic benefits of air conditioning cold source equipment are comprehensively considered, and a secondary comprehensive evaluation mathematical model of refrigerator is established. The model divides the 9 factors in the factor set into 3 subsets U1, U2 and U3 according to the initial investment, operating cost and safe and environmentally friendly transportation, and then obtains its single-factor evaluation matrix R1, R2 and R3 according to the first-level evaluation, gives the weight distribution of the 3 subsets U1, U2 and U3, conducts the second-level comprehensive evaluation, obtains the best equipment, and gives application examples, and the case calculation shows that the theoretical results are completely consistent with the actual results.
