What Makes Remote Jet Units Different
Unlike conventional suspended air-handling units, a remote jet unit does not connect to ductwork. Instead, it delivers conditioned air over a long throw directly into the space, which makes it a strong choice for large, high-ceiling halls and industrial plants.
Core of the Selection Process
The cooling and heating load follows the same calculation as a standard unit, and because the technology is energy efficient you can slightly reduce design values. Thermal performance selection is also similar. The real heart of the design, however, is airflow organization.
Key Requirements for the Jet
- Cold and warm air must reach the intended zone.
- Cold jets must not drop mid-flight and cause discomfort.
- Warm air must travel the required distance and position.
- The terminal temperature difference must meet the design spec.
Layout and Spacing
Once throw distance, mounting height, supply and room temperatures, and airflow are fixed, choose a unit that satisfies the points above. Account for interaction between multiple outlets: diffusion width is about 0.4 of the throw, so density should be a little smaller than that. Ceiling-attached flow extends roughly 1.4 times farther. Keep spacing near 0.4 of the throw, with coverage width 0.3โ0.6 of the throw. Single- or double-sided supply is possible, but verify reach for every building width to avoid short throws.
