[0002] When the indoor unit of the air conditioner is set at different positions in the room, it will affect the indoor air flow organization. The indoor people's evaluation of the air flow organization is also different. Under different air flow organization conditions, the human comfort and the cooling efficiency of the air conditioner are also different. Therefore, there is an urgent need for an evaluation method to evaluate the comprehensive performance of the air conditioner in order to select the best air conditioner layout point location to ensure that the room can have a ventilation system with better air flow organization, which is conducive to people working in a comfortable environment.

[0003] However, due to the polymorphism and ambiguity of scheme evaluation indicators, which are sometimes subjective and sometimes objective, it is very difficult to establish an evaluation system and determine evaluation indicators. It is difficult to use an accurate evaluation model to evaluate the pros and cons of an indoor air-conditioning layout scheme. Summary of the invention

[0004] The first purpose of the present invention is to provide an air conditioning comprehensive performance evaluation method based on the AHP-entropy weight method, which combines the subjectivity and objectivity of decision makers, effectively reduces the deviation caused by subjectivity or objectivity, improves the accuracy of the evaluation, and can realize the scientific selection of the air conditioning location in the room.

[0005] The second object of the present invention is to provide a computer device for implementing the above-mentioned air conditioning comprehensive performance evaluation method.

[0006] The third object of the present invention is to provide a readable storage medium for implementing the above-mentioned air conditioner comprehensive performance evaluation method.

[0007] To achieve the above first objective, the present invention provides an air conditioner comprehensive performance evaluation method, comprising: step 1, establishing a comprehensive performance evaluation system for air conditioners at different positions in a room, the comprehensive performance evaluation system comprising a target layer, an evaluation layer and a scheme layer; step 2, using a hierarchical analysis method to establish a judgment matrix for the evaluation layer and perform a consistency test, and calculating the weight Q of each evaluation index in the evaluation layer Y1 ; Use the hierarchical analysis method to establish the judgment matrix of the solution layer and perform consistency test, and calculate the weight Q of each evaluation index in the solution layer Y2 ; Combined with weight Q Y1 and weight Q Y2 , calculate the total subjective weight Q of each scheme under the hierarchical analysis method Y , Q Y＝ Q Y1 ×Q Y2; Step 3: Use the entropy weight method to calculate the weight H of each scheme in the scheme layer under each evaluation index of the evaluation layer ij and the weights of each evaluation index in the evaluation layer W j , and finally calculate the total objective weight R of each solution Z ; Step 4, combining the hierarchical analysis method and the entropy weight method, obtain the combined weights of the evaluation indicators of the evaluation layer and the combined weights of each scheme in the scheme layer, evaluate the comprehensive performance of the air conditioner in different positions in the room of the target layer to obtain the optimal air conditioner position, and determine the importance ranking of each evaluation indicator according to the evaluation indicator weight of the evaluation layer.

[0008] As can be seen from the above scheme, the present invention combines the subjective evaluation method with the objective evaluation method based on the AHP-entropy weight method, and provides an air conditioning comprehensive performance evaluation method, which improves the inadequacy of the traditional method that relies on the subjective scoring of experts, and at the same time takes the decision maker's preference for the subjective evaluation method and the objective evaluation method as a reference, thereby improving the accuracy of the evaluation and realizing the scientific selection of the air conditioning position in the room. The air conditioning comprehensive performance evaluation method provided by the present invention is relatively comprehensive, and can effectively reduce the deviation caused by subjective or objective bias, and is very useful in the comprehensive evaluation of multiple factors. At the same time, the present invention combines the AHP method and the entropy weight method and applies them to the selection of the air conditioning position in the room.

[0041] Air conditioning comprehensive performance evaluation method embodiment:

[0042] See also Figures 1 to 4 , the comprehensive performance evaluation methods of air conditioners include:

[0043] Step S1, such as Figure 2As shown, a comprehensive performance evaluation system for different positions of the air conditioner in the room is established, and the comprehensive performance evaluation system includes a target layer, an evaluation layer, and a solution layer. The target layer includes the comprehensive performance evaluation of the air conditioner in different positions in the room; the evaluation layer includes: energy utilization efficiency, air flow uniformity, personnel comfort, sewage discharge efficiency, and ventilation efficiency; the solution layer includes: the position of the air conditioner at position A, position B, position C, and position D. In other embodiments, the evaluation layer may also be at least two of the above-mentioned evaluation layer indicators, and the solution layer may also include at least two preset positions of the air conditioner.

[0044] Step S2: Use the analytic hierarchy process (AHP) to establish the judgment matrix of the evaluation layer and perform consistency test, and calculate the weight Q of each evaluation index in the evaluation layer. Y1 The analytic hierarchy process is used to establish the judgment matrix of the scheme layer and conduct consistency test, and calculate the weight Q of each evaluation index in the scheme layer. Y2 . Combined with weight Q Y1 and weight Q Y2 , calculate the total subjective weight Q of each scheme under the hierarchical analysis method Y , Q Y＝ Q Y1 ×Q Y2 .

[0045] See also Figure 3 In step S2, first, step S2.1 is executed to establish the judgment matrix of the evaluation layer using the AHP method. The judgment matrix of the evaluation layer is U = (u ij ) n×n ; Among them, u ij It represents the ratio of the impact of each evaluation index of the evaluation layer on the comprehensive benefits of air conditioning at different locations in the target layer; n is the order of the judgment matrix U.

[0046] Next, execute step S2.2 to perform a consistency check and determine whether the matrix passes the consistency check.

[0047] The formula for consistency test of the judgment matrix of the evaluation layer is:

[0048]

[0049] In the formula, C R is the consistency test coefficient of the judgment matrix; C I is the consistency index of the judgment matrix; R I is the average random consistency index; max is the maximum eigenvalue of the judgment matrix; n is the order of the judgment matrix;

[0050] When C R <0.1, the judgment matrix of the evaluation layer is determined to have passed the consistency test, and step S2.3 is executed to calculate the weight Q of each evaluation index in the evaluation layer.Y1 The method for calculating each evaluation index in the evaluation layer is: calculate the eigenvector corresponding to the maximum eigenvalue of the judgment matrix of the evaluation layer, standardize the vector, and obtain the weight Q of each evaluation index in the evaluation layer. Y1 .

[0051] When C R ≥0.1, the judgment matrix of the evaluation layer fails the consistency test and needs to be readjusted and tested again.

[0052] Next, execute step S2.4 and use the AHP method to establish a judgment matrix for the solution layer. The judgment matrix for the solution layer is V = (v ij ) t×t ; where v ij It represents the ratio of the impact of each evaluation index at the scheme level on the comprehensive benefits of the air conditioner at different positions in the room; t is the order of the judgment matrix V.

[0053] Next, execute step S2.5 to perform a consistency check and determine whether the matrix passes the consistency check.

[0054] If the consistency check is passed, execute step S2.6 to calculate the weight Q of each evaluation index in the solution layer. Y2 The method for calculating each evaluation index in the solution layer is: calculate the eigenvector corresponding to the maximum eigenvalue of the solution layer judgment matrix, and standardize the vector to obtain the weight Q of each evaluation index in the solution layer. Y2 .

[0055] If the consistency test fails, the judgment matrix needs to be readjusted and tested again.

[0056] Next, execute step S2.7, combining the weight Q Y1 and weight Q Y2 , calculate the total subjective weight Q of each scheme under the hierarchical analysis method Y , Q Y＝ Q Y1 ×Q Y2 .

[0057] Step S3: use the entropy weight method to calculate the weight H of each scheme in the scheme layer under each evaluation index of the evaluation layer ij and the weights of each evaluation index in the evaluation layer W j , and finally calculate the total objective weight R of each solution Z .

[0058] Step S4, combining the hierarchical analysis method and the entropy weight method, obtains the combined weights of the evaluation indicators of the evaluation layer and the combined weights of the schemes of the scheme layer, evaluates the comprehensive performance of the air conditioner at different positions in the room of the target layer to obtain the optimal air conditioner position, and determines the importance ranking of each evaluation indicator according to the evaluation indicator weight of the evaluation layer.

[0059] At the same time, the final result is determined according to the final combination weight. For example, when the air conditioner is in position B, the comprehensive performance is the best; from the perspective of the evaluation layer, when the air conditioner is in position A, the energy utilization rate is the highest; when the air conditioner is in position C, the cleanliness is the highest; when the air conditioner is in position D, the personnel comfort is higher.

[0060] See also Figure 4 In the above step S3, the method of using the entropy weight method to calculate the weight of each evaluation index and the total objective weight of each scheme is:

[0061] Step S3.1, listing the original data of the scheme according to statistical data and relevant standards;

[0062] Step S3.2, non-dimensionalize the original data and perform positive processing on the index data. Positive processing means that the larger the index, the better:

[0063]

[0064] Among them, x ij represents the value of the i-th indicator under the j-th indicator; Z ij represents the normalized data;

[0065] Step S3.3, calculate the contribution H of the jth factor in the i-th case ij :

[0066]

[0067] Step S3.4, calculate the information entropy E of each factor j :

[0068] Where ln(n)>0, H ij ≥0;

[0069] Step S3.5, calculate the weight W of each evaluation index according to the information entropy of each factor j :

[0070]

[0071] Step S3.6, calculate the objective weight R of each solution under the entropy weight method zi :

[0072]

[0073] In the above step S4, the method for obtaining the combined weight of the evaluation indexes at the evaluation layer and the combined weight W of each scheme at the scheme layer is:

[0074]

[0075] Among them, θ is the relative importance of decision maker’s preference, 0.3<θ<0.7;

[0076] r is the number of weighting methods, and r=2;

[0077] λ is the preference of decision makers for the weighting method, where the preference of decision makers for the analytic hierarchy process is λ1, 0<λ1<1; the preference of decision makers for the entropy weight method is λ2, 0<λ2<1, and λ1+λ2=1;

[0078] W (s) is the weight of the evaluation index under a certain weighting method;

[0079] β is the consistency coefficient of the weighting method. Since there are only two weighting methods, the value is β1=β2=0.5.

[0080] As can be seen from the above, the present invention combines the subjective evaluation method with the objective evaluation method based on the AHP-entropy weight method, and provides an air conditioning comprehensive performance evaluation method, which improves the inadequacy of the traditional method that relies on the subjective scoring of experts, and at the same time takes the decision maker's preference for the subjective evaluation method and the objective evaluation method as a reference, thereby improving the accuracy of the evaluation and realizing the scientific selection of the air conditioning position in the room. The air conditioning comprehensive performance evaluation method provided by the present invention is relatively comprehensive, and can effectively reduce the deviation caused by biased subjectivity or biased objectivity, and is very useful in the comprehensive evaluation of multiple factors. At the same time, the present invention combines the AHP method and the entropy weight method and applies them to the selection of the air conditioning position in the room. The method selects the best air conditioning layout point position, so that the room can have a ventilation system with better airflow organization, which is conducive to people working in a comfortable environment.
