Delta T is needed to calculate the efficiency of a specific condenser/heat exchanger, but it is not directly relevant to defining an overall system efficiency because EER/SEER/COP do not refer to the condenser alone. They quantify the total cooling/heating effect relative to compressor and fan input electrical power. Two different units may have the same EER but differing condenser delta T’s at the same entering water temperature.<o:p></o:p></span></p><p class=MsoNormal><span
