A gravity-driven flapper redirects cooling air to the bulb's upper side, reducing temperature imbalance even when the projector is inverted.

A thermostat varies compressor restart delay from weather and demand signals to cut HVAC energy use and peak load without hurting comfort.

Stored power and low-power control close the projector exhaust shutter during outages, blocking dust and insect ingress.

Split airflow heats one air stream while routing cooler air over the casing, improving flow uniformity and preventing dust-burning odors.

Angled vanes and vane openings redirect plenum air toward IT rack faces for more even cooling and lower airflow energy use.

A shaped blower duct and low-permeability opening region even out airflow over corona wires and grid electrodes to prevent charging defects.

Spiral-formed duct modules nest telescopically to cut transport volume, lower packaging costs, and simplify on-site air conduit assembly.

A left-right divided pipe hood separates inlet and outlet airflow to block recirculation, contamination, rain entry, and support heat exchange.

Warm recirculated air keeps integrated mixer flaps ice-free, cutting separate valves, piping, weight, and pressure loss.

A spiral heater at the snail-casing air exit boosts heat exchange for faster, more uniform bathroom airflow heating without cold drafts.
