In commercial refrigeration, what is the primary purpose of an air curtain?

The primary purpose of an air curtain in commercial refrigeration is to isolate a conditioned space. An air curtain creates a barrier of air that separates two different environments, such as the interior of a refrigerated area and the external environment. This barrier helps to maintain the temperature of the conditioned space by minimizing the amount of warm air that enters and cool air that escapes.

By effectively isolating the areas, air curtains allow for easier access for customers or staff without significantly disrupting the thermal comfort of the enclosed space. This isolation is crucial in commercial settings to ensure that refrigerated items remain at optimal storage temperatures, thereby enhancing food safety and reducing spoilage.

While enhancing energy efficiency, supporting temperature control, and reducing noise levels are benefits associated with air curtains, the primary function is focused on creating a physical barrier that maintains separation between different temperature zones.
