What impact does excessive supply air velocity have in a heating cycle of a heat pump?

Excessive supply air velocity during the heating cycle of a heat pump can lead to cool air complaints. When the air is moving too quickly, it may not have sufficient time to absorb heat from the heat exchanger, which prevents the air being delivered into the space from reaching a comfortable temperature. As a result, occupants may experience drafts or a chill, leading to discomfort and the perception that the system is not effectively heating the area. Maintaining an optimal supply air velocity ensures that the heated air is properly distributed throughout the space for better warmth and comfort.
