Definition & meaning

The term "air-curtain angle" refers to a specific measurement used in the context of commercial refrigeration equipment. It describes the angle formed by two lines when viewed in cross-section:

For equipment without doors and lacking a discharge air grille or honeycomb, the angle is between a vertical line drawn from the highest point on the manufacturer's recommended load limit line and the load limit line itself.
For all other doorless equipment, the angle is between a vertical line and a straight line connecting the inside edges of the discharge air opening and the return air opening.
