Abstract: Measured EER and COP are affected by the load under which an air conditioning, refrigeration or heating system is running; the load is a function of the evaporating and condensing temperatures. The invention makes adjustments for the purpose of maximizing measured EER and COP in a feedback loop utilized to optimize cooling or heating capacity relative to power consumed. The maximum EER is continuously achieved by incrementally adjusting each operating parameter to realize an incremental increase in EER, even as conditions such as ambient temperature are changing.

Abstract: Measured efficiency of an air conditioner or heat pump system is needed to accurately evaluate the economics of operating the system to provide a known amount of cooling. Significant degradation of air-conditioner and or heat pump components increases the operating cost by lowering the capacity of the system and/or increasing the power consumption. The invention provides measurement of the energy efficiency of any operating DX cooling, refrigeration, or heating unit, expressed in standard units by measuring the cooling or heating capacity and the power usage.
