NATE Air Distribution Practice Test

Question: 1 / 400

How should the air flow rate be adjusted in high sensible heat applications to avoid unwanted dehumidification?

Air flow rate should be decreased

Air flow rate should be increased

In high sensible heat applications, increasing the air flow rate is essential to prevent unwanted dehumidification. When there is a significant amount of sensible heat present—such as in environments that are generating or transferring heat—it is crucial to maintain a sufficient amount of air moving through the system.

By increasing the air flow rate, the system can effectively transport more heat without having a proportionate increase in moisture removal from the air. This helps to ensure that the air remains at the desired temperature without pulling too much moisture from the environment, which could lead to increased humidity levels or undesired drying effects.

This approach is particularly important in spaces where maintaining a balance between temperature and humidity is critical. Adjusting the air flow rate appropriately allows the system to handle high thermal loads while managing humidity levels effectively.
