At higher efficiency with lower condensing temperatures the airflow rate is high and the temperature difference between the condensing temperature and the air stream is small. As the condensing temperature is increased, this difference increases. At lower efficiency with high condensing pressures, since the assumed air flow rate is minimized based R410A Infinite Airflow Matched Airflow 4 5 6 7 8 9 10 11 Cooling COP 19 Average gas cooler [m3/min/kW cooling] temperature diff.
