ABSTRACT:
A method for determining airflow through an evaporator coil in a vapor compression cycle by measuring the moist air conditions entering and leaving the coil, and various temperatures and pressures in the refrigerant of the vapor compression cycle. The mass airflow rate and the volumetric airflow rate are then determined.
