Points out that the current energy efficiency evaluating system using the indices like total annual electricity consumption for air conditioning and electricity consumption per unit area for air conditioning cannot provide a full and correct evaluation of a central air conditioning system. Puts forward a new evaluating and tracking system, which can track, monitor, count and display real-time refrigerating output, real-time power, real-time electricity consumption, real-time energy efficiency, average historical integrated energy efficiency, real-time load ratio, average historical load ratio, etc. Provides some examples to illustrate the application of the new evaluating system.
