  • Method and system for evaluating the efficiency of an air conditioning apparatus
    Patent number: 7945423
    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.

  • Method and system for evaluating the efficiency of an air conditioning apparatus
    Patent number: 6973410
    Abstract: Air conditioning chiller operating efficiency is evaluated in response to chiller operating parameters input to a computing device which calculates separately the efficiencies of the condenser and evaporator components of the chiller. Additional efficiency calculations are performed to identify specific causes of inefficiency in the condenser and evaporator. The computing device also adjusts the efficiency calculations as appropriate to account for actual compressor current load conditions. The device determines whether chiller efficiency is being compromised by poor performance of one or more chiller components, calculates inefficiency values, estimates the cost of the inefficiency, identifies specific causes of the inefficiency, and suggests appropriate remedial actions to restore maximum efficiency of the chiller.
