Heat exchange efficiency (percentage) = (outflow air temperature - inflow air temperature) ÷ (inflow cooling water temperature - inflow air temperature), that is, P(%)=(T _{air outlet} -T _{air inlet} )÷(T _{water inlet} -T _{air inlet} ).

Taking the experimental data of this creation as an example, the temperature of the airflow flowing into the high-efficiency heat exchanger E from the first direction is measured as 23 degrees Celsius (that is, 23°C), and the temperature of the cooling water flowing into the water inlet 5 is measured as 21°C After heat exchange, the temperature of the airflow flowing out of the high-efficiency heat exchanger E from the second direction is measured to be 21.04°C, and the heat exchange efficiency is calculated to be 98% through the above heat exchange efficiency calculation formula.
