  • In order to evaluate the energy efficiency of the ammonia refrigeration system, a novel two-dimensional matrix model was proposed. Based on thorough analysis of the popular evaluation methods, analytic hierarchy process-fuzzy comprehensive evaluation and information entropy method, a new combination weight evaluation method was put forward with the least squire. What's more, for better performance comparison, necessary actual cases were conducted and it proved that the new method has better precision, higher linearity and greater consistence with actual energy efficiency. Also, the energy efficiency state can be assessed instantly with this method and by adjusting necessary parameters the system can operate more optimally with less energy consumption.
