What is the typical air velocity range through comfort cooling evaporators?

The typical air velocity range through comfort cooling evaporators is indeed in the range of 300 to 500 feet per minute (fpm). This range is established to ensure optimal heat exchange efficiency while maintaining a comfortable environment for occupants.

At air velocities within this range, the evaporator can effectively absorb heat from the air, allowing for effective cooling while minimizing noise levels. Higher velocities can lead to increased noise and reduced comfort, as air movement becomes more noticeable and can create drafts, making a space feel less pleasant. Additionally, velocities that are too low can result in inadequate heat transfer, leading to inefficient cooling performance.

Overall, maintaining an air velocity within the 300-500 fpm range strikes a balance between effective cooling, efficiency, and comfort, which is crucial in both residential and commercial air conditioning systems.
