In a cooling operation, where is the ideal location for a return intake?

In a cooling operation, placing the return intake near the ceiling is ideal due to the natural behavior of warm air. When air is cooled, it becomes denser and sinks, while warmer air rises to the top of the room. By positioning the return air intake near the ceiling, the HVAC system can effectively capture the warmer air that accumulates at the upper levels. This helps in maintaining a balanced temperature throughout the space and improves the efficiency of the cooling system.

Additionally, this placement allows for better circulation of air as the system can effectively replenish the cooler, denser air towards the floor while removing the warmer air that has accumulated near the ceiling. This not only enhances comfort but also minimizes the risk of hot spots in the room, leading to a more uniform and efficient cooling process.
