What air movement is standard for heat pumps?

In heat pump systems, air movement is commonly measured in cubic feet per minute (cfm) per ton of cooling capacity. The standard air movement for heat pumps is typically set at 400 cfm per ton. This figure is important because it helps ensure that the system operates efficiently, delivering the necessary air flow to effectively transfer heat.

When 400 cfm per ton is maintained, it allows for proper heat exchange in heat pump applications whether they are heating or cooling. If the air movement is too low, it can lead to inadequate heating or cooling and potential system issues. Conversely, excessive air movement can increase noise and potentially lead to inefficiencies in energy use.

This established standard of 400 cfm per ton reflects industry practices, ensuring that the system can adequately manage the thermal load it is designed to handle while maximizing efficiency and comfort.
