• Cooling a 25 m work line with concentrated equipment heat
• Reducing equipment and operating costs compared with whole-space cooling
• Precision cool-air delivery focused on workers

Inefficient whole-factory cooling

Only the work line required cooling, but cooling the entire factory demanded excessive equipment capacity and operating costs.

Limited cooling along the work line

Cool air could not be distributed evenly along the full 25 m line, leaving occupied areas insufficiently cooled.

Concentrated machine heat

Heat from large equipment accumulated around workers, creating a need for spot cooling.

Spot cooling along 25 m

Fabric ducts were concentrated above the actual 25 m production line rather than distributed across the entire factory.

Precision discharge toward workers

Laser-hole positions and angles directed cool air into worker areas between machines, creating targeted cooling paths.

Adaptable to line changes

A modular structure allowed flexible adjustment when equipment or production lines moved.

Approximately 24°C in worker zones

Spot cooling maintained approximately 24°C around workers despite substantial machine heat, providing cooling they could feel.

Lower costs than whole-space cooling

Supplying cool air along the 25 m work line reduced unnecessary cooling of unused space and lowered both equipment investment and operating costs.

Suitability for defense manufacturing

The project demonstrated effective spot cooling amid complex equipment and crane routes, establishing suitability for industrial manufacturing environments.
