What is the term for heat conveyed on currents of air?

The term for heat conveyed on currents of air is convection. This process occurs when warmer air, which is less dense, rises and allows cooler air to take its place. In this way, heat is transferred through the movement of air masses rather than through direct contact (as in conduction) or through electromagnetic waves (as in radiation).

Convection plays a significant role in various applications, including heating and cooling systems, where air is moved to distribute thermal energy effectively throughout a space. It’s the mechanism that helps to equalize temperatures within rooms and buildings, ensuring that specific areas do not become overly warm or chilly compared to others.

Understanding convection is crucial in the sheet metal industry, particularly when designing ventilation systems. Properly accounting for air movement and heat transfer ensures these systems operate efficiently, providing comfort and energy savings in residential and commercial settings.
