A better way to evaluate the KBEM is to compare its optimization results with those obtained by the state-of-the-art method.
Case Studies that Compare the KBEM with the Existing Method
In order to compare the KBEM with the state-of-the-art method, we use the KBEM to optimize the two cases that are studied by the existing method (Domanski et al.
Figures 5a and 5b show the optimal RC provided by the KBEM and the existing method (Domanski et al.
Figures 6a and 6b show the optimal RC provided by the KBEM and the existing method (Domanski et al.
In order to evaluate the adaptability of the KBEM for different heat exchangers, two other different heat exchangers, including evaporator and condenser, are selected as test cases.
As the KBEM is developed by adding the KOM to the IGA, the difference between the KBEM and the IGA mainly depends on the effect of the KOM.
The figures show that the RC solution obtained by the KBEM within ten generations is better than that obtained by the IGA, even at 200 generation.
Figures 9a and 9b show the RC designs recommended by the KBEM for Case C with uniform inlet airflow and nonuniform inlet airflow, respectively.
Figures 11a and 11b show the RC designs recommend by the KBEM for Case D with uniform inlet airflow and nonuniform inlet airflow, respectively.
This further proves that the KBEM has the ability to consider the feasibility of manufacturing the RC designs but lacks the capability to consider how to reduce the difficulty.
