In early works done by authors, performance analysis of refrigeration systems such as power
input, refrigeration load and coefficient of performance (COP) was investigated. In this article a new
function called “Coefficient of Performance Exergy” or COPE has been introduced. Two objective functions
of coefficient of performance exergy and exergy destruction are optimized simultaneously using the multiobjective
optimization algorithm NSGAII. COPE has been maximized and exergy destruction has been
minimized in order to get the best performance. Decision making has been done by means of two methods
of LINAMP and TOPSIS. Finally an error analysis done for optimized values shows that LINAMP method
is preferable against TOPSIS method.
