Abstract
The applicant describes a system and methods of calculating the overall operating efficiency of an air conditioning chiller that evaluates efficiency of the component parts of the chiller and generates an overall efficiency based on these component efficiency values. If the overall chiller efficiency is less than the maximum attainable chiller efficiency, the cost of the inefficiency is calculated and presented to the user. Recommendations for corrective action to restore maximum chiller efficiency are identified and presented to the user. The system also adjusts the efficiency calculations as appropriate to account for actual compressor current load conditions.
